We are perhaps best known as a leading ocean carrier for the transport of cars — carrying nearly two million vehicles each year. But take the “car” out of cargo and you will discover that Wallenius Wilhelmsen transports a whole lot more. Not just cars Wallenius Wilhelmsen transports all types of static cargo, which by definition includes any cargo that must be lifted or towed on board using special trailers. We are experts in the field of transportation of general break bulk products and other non-containerised cargo, which often require special handling and specialised solutions. Wallenius Wilhelmsen takes great pride in providing both. Flexible vessels Smart ocean transport of huge volumes of a wide variety of cargo requires smart vessels. Our vessels are designed with specific transport needs in mind and with the flexibility to accommodate as many different types of cargo as possible. To keep pace with our customers’ changing needs, we are continually in the process of evaluating and updating the design of our vessels. Innovative cargo handling As cargoes have become less standardised, they have also become more challenging to transport. We at Wallenius Wilhelmsen are committed to accepting this challenge. If our existing equipment does not meet your cargo requirements, we ask design engineers to craft a solution. This creative approach to cargo handling is why customers with non-standardised cargo requirements rely on Wallenius Wilhelmsen — time and time again. Seaworthy handling Delivery in perfect condition Quality is the hallmark of cargo handling at Wallenius Wilhelmsen. No matter how unusual the cargo, quality for us is synonymous with delivery in perfect condition. Delivery in perfect condition is a fundamental way of thinking at Wallenius Wilhelmsen. This is because cargo care is not only a business imperative, but a way of life for many of our employees. It is not unusual, for example, to find a few of us on hand to witness the loading or discharging of an unusual item of cargo — even when duty does not warrant our presence. Confidence characterises the way in which our customers entrust Wallenius Wilhelmsen with their cargo. This confidence stems from our zero-tolerance policy towards cargo damage, which is rigorously enforced through the application of best practices and the continual improvement of handling procedures. Wallenius Wilhelmsen also encourages the “lesspack” concept of minimal cargo packaging, which is based on the philosophy that the more we can see of the cargo, the better we can cater to its special needs. The less-pack concept also has the added benefit of reducing packaging costs. Above all, customer satisfaction is the determining factor behind Wallenius Wilhelmsen’s cargo handling policies and procedures. Handling 5 Damage prevention programme A belief in having the best policy, however, means little unless this creed is put into practice. Through practical hands-on procedures, the Wallenius Wilhelmsen damage prevention programme ensures excellent quality of cargo handling and safe, efficient transport. We have systems in place to measure performance in order to be in a position to continually improve our operations. Wallenius Wilhelmsen provides strong operational supervision while handling cargo. At all major ports Wallenius Wilhelmsen’s staff, together with the vessel’s crew, oversee operations to ensure damage-free loading and discharging of cargo. This ensures proper cargo handling procedures are applied at all times. In all other ports, the vessel’s crew oversee loading and discharging operations. In addition, our customers provide us with feedback on our performance on a regular basis. We want to be the first to know about any problems as well as be the first to receive acclaim. As a consequence, we have an ongoing dialogue with our customers to establish what improvements they would like to see. Wallenius Wilhelmsen also encourages input from our employees as well as from stevedores and lashing subcontractors. Because these individuals work on the front line, they have first-hand experience and knowledge of what can go wrong and can make recommendations about how to improve handling procedures. Handling 7 A personal commitment to quality Secure handling can only be guaranteed through the expert knowledge and dedication of the people who take care of your cargo. Every individual at Wallenius Wilhelmsen, whether working directly with the cargo itself, or having responsibility for its transport from a distance, makes a personal commitment to quality cargo care. This commitment is reinforced through continuous training and education. Our cargo handling specialists stay abreast of advances being made in best practices and apply this knowledge by sharpening their practical skills under real operational conditions. Wallenius Wilhelmsen also ensures that any cargo handling knowledge acquired over the years is shared throughout the company. Our instructions manuals cover everything our personnel need to know about handling cargo — from what clothing is required during loading, lashing and stowage procedures to the supervision of operations, to safety issues applicable to all areas of the handling process. The proof of our commitment lies in what we have accomplished, which is demonstrated by our sound track record for delivery in perfect condition. It is also evident in what we set out to do: to continually improve cargo handling procedures. Continual improvements After analysing cargo handling data and feedback information from our customers, employees and subcontractors, we at Wallenius Wilhelmsen are then in an ideal position to identify and implement improved handling practices throughout the organisation. All data compiled is made available to Wallenius Wilhelmsen staff around the world. This enables us to recognise trends that may help prevent future damage and to determine the root cause of problems should they occur. To ensure quality, we constantly monitor changes in procedures, thus guaranteeing that improvements to cargo handling operations are fully realised. If and when required, we refine our handling practices to enhance technique and performance. Moving cargo across land and sea Longer, taller, heavier… it’s all on its way As a global operator, we are able to transport almost any product to almost any destination around the world. The transport of cargo that requires special know-how is an area in which we at Wallenius Wilhelmsen are experts. Our cargo team looks after a variety of static cargoes that require special attention throughout the voyage. Special cargoes call for vessels that offer a degree of flexibility. Our vessels are highly adaptable and capable of accommodating a wide variety of cargoes. In addition, we develop our own handling procedures and methods for securing materials to reduce handling times and to minimise risks. The following is a brief presentation of the wide variety of special considerations applied by Wallenius Wilhelmsen when handling static cargo. Static Cargo 9 Boats and yachts Sailing on board a Wallenius Wilhelmsen vessel is an unusual mode of transport for most yachts, sailing and trailer boats. However, these boats and yachts will, most likely, never experience a smoother journey. Wallenius Wilhelmsen provides the utmost care and attention to ensure safe and secure ocean transport. Wallenius Wilhelmsen offers several methods for loading and discharging yachts, sailing and trailer boats. Most often, smaller boats and yachts arrive at the port of loading on their own trailers and are carefully towed on board. In cases where larger boats and yachts reach the port in cradles, Wallenius Wilhelmsen loads both the cradle and its cargo onto a rolltrailer for stowage on board. At the port of discharge, we can also lift or deliver boats and yachts directly into the water using either a floating crane, a mobile crane or a port crane. Below deck stowage Wallenius Wilhelmsen RoRo vessels can accommodate boats and yachts including cradle as tall as 5.25 m (17 ft, 6 in) below deck. This measurement takes into consideration the height of a standard rolltrailer and a clearance of 20 cm (8 in) between the top of the cargo and the deck above, which is required for safe operations. Wallenius Wilhelmsen secures cradles to rolltrailers by using lashing chains, and then secures the trailers with its cargo to the deck of the vessel. When transporting a boat or yacht on its own trailer, the height of the trailer and the roof clearance must be taken into consideration. On deck stowage Almost any cargo which exceeds the maximum height of 5.25 m for stowage below deck can be transported on the upper deck. Loading directly out of and discharging directly into the water is possible with the use of a crane. Large yachts travelling on the weather deck are secured with additional lashing from the hull of the yacht to the deck of the vessel. Creative weather deck transport Occupying almost all of the space nearest the stern on the weather deck is a 33-m-long by 17-m-wide catamaran. While sailing in the Southern Ocean, its mast broke and the task of returning the cargo to its home port in England was entrusted to Wallenius Wilhelmsen. The Operations Director of the U.K.-based specialist freight forwarder responsible for bringing the catamaran home is on hand to watch the discharging. This is not the first time he has relied on Wallenius Wilhelmsen for quality service. “Wallenius Wilhelmsen provides good service, otherwise we would not have worked with them this long or this closely,” he says. “The company is probably the number one supplier in terms of getting the job done right at the right time.” The massive size of the catamaran does not leave much room to manoeuvre. The huge floating crane that has been called in to lift the catamaran off the deck places it gently into the water. Though this catamaran is the largest boat ever to be shipped on a Wallenius Wilhelmsen weather deck, it most definitely will not be the last. Static Cargo 11 Machinery and machine tools Wallenius Wilhelmsen carries large volumes of machinery and machine tools around the world. Often fitted with sophisticated electronics, these loads require careful handling. Consignments can vary from individual machine tools to full production lines or even whole factories, with sizes and weights that may differ with each shipment. Wallenius Wilhelmsen provides strong operational supervision while handling this valuable cargo. Supervisors are on hand to ensure delivery in perfect condition so that the production lines or factories that require this equipment can open on time and without any delay. Wallenius Wilhelmsen encourages shippers to send cargo using minimal packaging. Apart from a sturdy base, consignments are often just wrapped with plastic sheeting, which enables us to clearly see the cargo for proper handling and stowage. This also reduces the costs for our customers. Other cargo, such as printing machines and printing presses, are transported in crates on rolltrailers. Handling Machinery. The size and weight of the machinery being shipped determine the type of equipment used to load, stow and discharge the cargo. Wallenius Wilhelmsen handles most machinery using standard rolltrailers that have a gross capacity of up to 120 tons. For cargo weighing between 120 and 180 tons, Wallenius Wilhelmsen uses its own specially designed Samson heavy lift trailer. Wallenius Wilhelmsen utilises jack-up trailers, also known as cometto trailers that are configured to the exact requirements of the cargo weighing in excess of 180 tons. For the heaviest cargo, Wallenius Wilhelmsen uses a 12-axle jack-up trailer. Towing or trailering cargo on board eliminates the risk of potential damage that is ever present during lift-on/lift-off operations. Machine tools. Machine tools include any machinery used for cutting, shaping or forming of metal. These include sophisticated production units for the automotive and aircraft manufacturing industries, some of which are fitted with sophisticated computer units. Any machine tools that come in cases, wooden crates or steel crates are generally carried on rolltrailers or bolsters. Stowage Wallenius Wilhelmsen usually stows cargo on rolltrailers, but bolsters are also used for smaller sized cargo. Cargo is securely lashed to the rolltrailers and bolsters, which in turn are secured to the deck of the vessel. Due care and consideration are given to secure cargo to avoid mechanical stress which can cause damage. Static Cargo 13 Mining equipment Wallenius Wilhelmsen offers excellent transport solutions for mining equipment. We transport large volumes of cargo, either as complete units or as individual components. Our vessels which offer a high degree of flexibility are built to accommodate a wide variety of unwieldy, heavy cargo — from drilling machines and mine roof supports to conveyor belts and mining construction equipment. Our RoRo carriers have stern ramps that are capable of supporting a weight of up to 420 tons and stern ramp openings that are 12 m wide by 6.4 m high. Wallenius Wilhelmsen encourages shippers to send cargoes ‘as is’. No additional packaging is required. This enables our cargo handling specialists to clearly see the cargo and to ensure proper handling and stowage, whilst also reducing costs for the customer. Handling Wallenius Wilhelmsen handles most mining equipment using rolltrailers which have a capacity to handle up to 120 tons. For cargo weighing between 120 and 180 tons, we use our own specially designed Samson heavy-lift trailers. For cargo that exceeds the capacity of our own equipment, Wallenius Wilhelmsen utilises jack-up trailers, also known as cometto trailers, which can be configured to the exact requirements of the cargo. Towing or trailering cargo on board eliminates the risk of potential damage during lift-on/lift-off operations. Stowage On most trade routes, equipment weighing up to 340 tons can be stowed below deck. Depending on the type of cargo, equipment may be securely lashed and stowed on blocks and beams, or alternatively, it may also remain on the trailer used to load the equipment for the entire duration of the ocean voyage. Static Cargo 15 Power generation equipment Power generation equipment is exceptionally large and heavy cargo. As such, it requires exceptional attention to detail for secure handling and safe transport. Wallenius Wilhelmsen provides both. Every day Wallenius Wilhelmsen is involved in transporting all types of power generation equipment — from 144-ton generators to 305-ton turbines — somewhere around the globe. This experience, in addition to giving us insight into exactly how each type of equipment should be handled and stowed, also ensures operations can be run more efficiently. Then there is always the unexpected challenge. We have encountered our fair share and can rely on both our ingenuity and expertise to come up with innovative transport solutions. Tackling these challenges is part of our commitment to delivering your cargo in perfect condition, every time. Handling Wallenius Wilhelmsen cargo specialists are on hand every step of the way to ensure proper handling and stowage. Different types of trailers, our own as well as leased, are used to transport the equipment. Rolltrailers handle cargo, such as generators and power plant equipment in crates, weighing up to 120 tons. Samson heavy-lift trailers, specially developed by Wallenius Wilhelmsen, carry heavier equipment such as transformers that have a gross weight of up to 180 tons. Even heavier loads can be accommodated on 12axle jack-up trailers, popularly known as cometto trailers. These sectional jack-up trailers are configured according to the size and weight of the cargo. Stowage Equipment, such as generators, turbines and transformers, are stowed below deck. Wallenius Wilhelmsen is able to stow cargo weighing up to 340 tons below deck. Equipment may be stowed and securely lashed on blocks and beams, or alternately, it may also remain on the trailer used to load the equipment for the entire duration of the ocean voyage. Static Cargo 17 Wind turbine equipment Wallenius Wilhelmsen transports increasing volumes of wind turbine equipment around the globe. Because construction and maintenance costs are similar whether the turbine is large or small, utility companies are building the largest feasible turbines to gain competitive advantage. Our job is simply to deliver. Whether just-in-time delivery for a new wind farm site or ongoing transport of replacement parts, Wallenius Wilhelmsen is up to the challenge. Our cargo specialists pay great attention to details — to every aspect of loading, stowage and discharging of tower sections, individual nacelles and hubs or complete wind turbines. For example, we know that blades of all sizes are susceptible to windage. Therefore when placing blades on the weather deck, our crane operators exercise extreme control to ensure proper, incident-free loading. Transport to wherever the wind blows Wallenius Wilhelmsen moves wind turbine equipment. Here are a few examples: Three 39-metre replacement windmill blades in a single shipment. Eighteen 22-metre windmill blades in a single shipment. Shipment of a 40,000-kg nacelle, a 25,000-kg hub and a 43,000-kg drive chain. Three tower sections of varying weights and sizes: Weight 44,500 kg 39,500 kg 31,500 kg Size 15.2 m x 4.11 m x 3.78 m 26.55 m x 3.87 m x 2.9 m 15.25 m x 3.78 m x 3.78 m Static Cargo 19 Below deck stowage On deck stowage Nacelles and hubs. These are usually packed in fibreglass moulds for protection. Wallenius Wilhelmsen usually loads and transports an 80-ton nacelle and a 10ton hub together on a 40-foot rolltrailer. Chains secure the cargo onto the rolltrailer, which in turn is lashed with chains onto the deck of the vessel. Loose blades with deck supports. Blades that are longer than 25 m are usually lifted by crane onto and off the weather deck of the vessel where they rest on deck supports. Loose blades with deck supports. Loading windmill blades requires open space for safe and efficient operations, which is why loose blades that are wrapped in plastic are often the first cargo to go on board at the port of loading. Blades with deck supports are loaded onto 25-m shuttle trailers. Once on board, Wallenius Wilhelmsen uses specially manufactured bottom lifting devices to stow the cargo. Blades are stowed and secured side by side, turned tip to base, to ensure the most efficient utilisation of space. Blades in stackable frames. Shippers also deliver pairs of blades in stackable frames with each end of the blade secured within the frame. These frames can be efficiently stacked below deck. Towers. Wind towers are generally divided into three sections in lengths of approximately 25 m each. Each section can weigh anything between 15 and 40 tons. Tower sections are usually handled on rolltrailers and secured for transport on the weather deck. Railway equipment Though not an obvious means of transport, a large number of railcars are transported each year by sea. Wallenius Wilhelmsen is one of the industry’s leading railcar carriers. Wallenius Wilhelmsen has developed two unique concepts for handling railcars, one for fully assembled railcars with bogies and one for railcar shells without bogies. Rolltrailers, also known as mafi trailers, are also used to transport railcars. Rubber Tyre Bogies Wallenius Wilhelmsen carries railcar shells without bogies on board our RoRo vessels using Rubber Tyre Bogies. These are customised to fit the specific railcar model to be transported. During typical operations railcars are lifted only twice: once onto the Rubber Tyre Bogies and once off. Once situated on the Rubber Tyre Bogies, railcars are then towed on board for stowage below deck. Rubber Tyre Bogies are equipped with air brakes for road use. If road permits have been granted in the exporting country and in the country of destination, Wallenius Wilhelmsen can offer door-to-door delivery of railcars. Wallenius Wilhelmsen Rubber Tyre Bogies have been granted road permits for use in the United States. Tight space, tight deadline How do you get a 31-m railcar to withstand a much steeper climb than it has been built for and then turn it more or less 90 degrees inside a 32-m-wide vessel? This was the challenge that Wallenius Wilhelmsen was faced with in Bremerhaven, Germany. A special design team quickly created the perfect solution by simply shortening two rolltrailers and fitting each with a turntable. These were then placed under each end of the railcar in a way that relieved the sensitive bogie sets from any stress. Once inside the vessel, the turntables made it possible to swing the railcar with very little radius, contributing to the success of loading and discharging operations. Air Shuttle The Air Shuttle trailer is specially designed by Wallenius Wilhelmsen for loading and discharging fully assembled railcars with rail bogies attached. Fitted with rails on top and a pneumatic system, the Air Shuttle can raise and lower the trailer bed to ground level, eliminating the need to lift the cargo. Instead, railcars weighing up to 47.5 tons can be towed from rail tracks directly on to the Air Shuttle. Once the railcars are wheeled onto the vessel, the shuttle is removed and deployed elsewhere, saving time, cutting costs and improving the overall quality of service. Greenhofer Greenhofer is the Air Shuttle’s “little brother” and functions very much in the same way. However, the Greenhofer can only transport a maximum weight of up to 15 tons, which makes it ideal for the transport of railcar shells and light railcars with exposed rail bogies or with rail bogies in crates. Static Cargo 21 Natural rubber Wallenius Wilhelmsen transports significant volumes of natural rubber. Though not extremely heavy, high or bulky, this sensitive cargo requires special handling procedures. Through years of practical experience, Wallenius Wilhelmsen has learned about the unique characteristics of natural rubber, especially its sensitivity to moisture. Due to this sensitivity, this type of cargo is always loaded and stored under cover. Wallenius Wilhelmsen has developed secure handling procedures to ensure that natural rubber retains its key properties and characteristics necessary for the onward manufacture into finished products. Handling and stowage Wallenius Wilhelmsen handles consignments of natural rubber that are packed in steel or wooden crates or shrink-wrapped on wooden pallets, by using trucks or road trailers to transport the pallets or crates on board. Small forklifts are then used to lift and stow the cargo. Shrink-wrapped units and wooden crates are carefully stacked, three high, below deck. When stacked three high, shrink-wrapped units may be staggered. Strong plywood boards are placed between the layers to provide extra support. Metal crates may be stacked four high and cardboard is placed between the layers. Sturdy lashings secure the cargo, and corner protectors prevent damage to the edges. To prevent damage to cargo, the dew point is constantly measured below deck and proper ventilation facilitates the prevention of excess humidity. Static Cargo 23 Steel Whether in sheets, coils and cable reels or as pipes and beams, all types of special steel are transported on board Wallenius Wilhelmsen vessels. We move large lots of low-grade steel as well as smaller lots of highgrade steel, such as stainless steel, all over the world. To accommodate these heavy loads, our RoRo vessels have deck strengths on the tank top of up to 10 tons per square metre. Wallenius Wilhelmsen is well aware that steel is highly susceptible to corrosion and therefore we ensure that this corrosion-sensitive cargo is always loaded and discharged in dry weather conditions or under cover. We also know that steel coils are particularly sensitive to mechanical damage and to pressure derived from excessive handling and that any distortion is detrimental to further processing. To prevent damage, we therefore prefer to load sheets and pipes on bolsters. Handling Coils. Depending on their size and weight, coils are handled with forklifts with special attachments. For large steel coils, we use a forklift attachment fitted with a large rod. Smaller coils are handled with a forklift fitted with a suitable piece of pipe threaded onto the prongs. Sheets. Bolsters or rolltrailers are used to transport stainless steel sheets. To prevent the wavering of the sheets, sufficient interlayer dunnage is placed underneath each sheet or pack of sheets. Edges and corners are also protected. Stainless steel is always stored under cover in the terminal on flat, dry, clean surface areas. Pipes. Small to medium-sized pipes are carried on bolsters, which may be used for door-to-door transport. Pipes are secured to the bolster with wire or chains of sufficient strength, and the length of the pipe may sometimes exceed that of the bolster itself. Exceptionally large pipes are generally handled as loose cargo, while smaller pipes may be bundled for handling by a medium-sized forklift. Stowage Due to its weight, steel is generally stowed in the lower hold. These holds are protected from weather and seawater to minimise the risk of corrosion. Smaller volumes may be stowed under ramps. Static Cargo 25 Bridging distances from shore to sea Reliable equipment to pull it off Loading, stowing and discharging cargo are delicate operational procedures that demand both experienced personnel as well as purpose-built equipment. The longer, the taller and the heavier the cargo, the greater the demands. Whatever your shipping needs, Wallenius Wilhelmsen can supply the equipment necessary to ensure that we handle your cargo in the safest and most efficient manner possible. If the equipment does not exist to handle your particular cargo, our design specialists use their ingenuity to customise a solution. Our range of well-adapted equipment facilitates loading and discharging operations. Our equipment is clean, readily accessible and undergoes scheduled maintenance and inspections. Wallenius Wilhelmsen personnel make sure that operations are conducted safely and without incident in keeping with our zerotolerance policy. Here are some examples of the reliable equipment that we use to handle your cargo. Equipment 27 Technical specifications Dimensions* Maximum gross weight 92 tons Capacity (gross) 60 - 120 tons Maximum length (in feet) 20, 40, 60, 80 Maximum width 2.50 m (8 feet) Maximum height when stowed 0.85 m Maximum height with cargo 5.6 m (PCTC) 5.5 m (RoRo) Acceptable rear trailer overhang 3 m (10 feet) * Based on standard 100-ton rolltrailer Rolltrailers For large, heavy cargo Rolltrailers, which are also known as mafi trailers, are designed for RoRo transport of large heavy units, but can also be used for most types of general cargo and containers. Rolltrailers are also frequently used for transporting cargo into and out of the lower decks of a vessel, where the cargo is taken off the trailer and stowed loose and secured. Securing cargo Wallenius Wilhelmsen rolltrailers have wooden floors and rubber mats to provide a non-skid surface. Lashing rings or bars are located on both sides and at the front and rear of the trailer. Depending on the type of cargo, Wallenius Wilhelmsen uses chains, wires or web lashings to secure the cargo to the rolltrailer. Additional lashings from the cargo directly to the deck of the vessel are used to secure large and heavy cargo and rolltrailers are secured to the deck with chains. For longer, shorter or narrower cargo Wallenius Wilhelmsen has solutions for heavy cargo that is longer, shorter or narrower than our standard rolltrailers. For longer cargo, rolltrailers can be extended by adding a bolster that is positioned 3 m (10 ft) from the rear end of the rolltrailer and secured by a twist lock. For shorter cargo, steel beams or heavy timber may be placed length-wise beneath the cargo and on top of the trailer to distribute the weight. For narrow cargo that is less than 3 m wide, the cargo is placed on steel beams or on heavy timber blocks extending from side beam to side beam. One of the world’s largest fleets Wallenius Wilhelmsen operates one of the world’s largest fleets of rolltrailers, more than 1,200 in all. It is a diverse fleet ranging in length from 6 to 24.38 m and in capacity from 25 to 120 tons. Equipment 29 Technical specifications Dimensions Jack-up trailer For exceptionally heavy cargo Maximum gross weight Up to 340 tons Configuration Units in four-axle sections Maximum configuration 12 axles long x 8 m wide Maximum size Customised Maximum weight Customised Jack-up, or cometto trailers are built to carry exceptionally heavy cargo weighing several hundred tons. A jackup trailer consists of four-axle sections that can be configured to carry cargo of almost any size and weight. The largest configuration is 12 axles long by 8 m wide and rests on 192 wheels. Before transfer onto a jack-up trailer, the cargo is placed on beams and support blocks in the terminal. Steel support blocks are required for heavy units that weigh 120 tons or more. For cargo weighing less than 120 tons, heavy timber support blocks may be used. Cargo specialists use the built-in hydraulic system to lower the trailer into position to take on cargo, carefully placing the trailer beneath the cargo. Once in the correct position, the trailer is elevated, carrying the full weight of the cargo and steel beams. The support blocks are then removed and the trailer is towed on board by one or more heavy-duty tow trucks. Once the trailer is in the correct position on board, support blocks are placed under the beams. The trailer is lowered until the full weight of the cargo rests on the support blocks. The trailer is then removed and the cargo secured. This operation is reversed at the port of discharge. Equipment 31 Technical specifications Dimensions Maximum payload (gross) 180 tons Samson heavy-lift trailer For small and medium-sized cargo Maximum cargo length 8 - 11 m Maximum width 3m Turning radius 43 m (141 feet) The Samson heavy-lift trailer is well suited for small and medium-sized lifts, such as transformers, generators and turbines. Specially designed by Wallenius Wilhelmsen, this heavy-duty trailer consists of a platform with two-wheel bogies with two axles each. Many of our vessels can accept a four-axle trailer with a gross weight of 180 tons, without exceeding the maximum permissible axle load. Before loading, cargo is placed on the platform of the trailer. The trailer with the cargo is then transported by two tow tractors to a stowage location on board. Using an electric hydraulic pump which raises the integrated hydraulic pistons, the platform is elevated to enable the positioning of heavy timber or steel supports. Heavy timber or steel blocks are placed under the side beams of the platform, after which the platform is then lowered so that it rests on the blocks. The bogies can now be pulled out from underneath the platform and used for the next lift. At the port of discharge the procedures are reversed. Wallenius Wilhelmsen has manufactured 12 Samson heavy-lift trailers: eight 8-m-long flats and four 10-mlong flats. All platforms are 3 m wide. Wallenius Wilhelmsen has five sets of bogies with electrically powered hydraulic pumps. Equipment 33 Air Shuttle Technical specifications Dimensions Maximum payload 47.5 tons Maximum length (adjustable) 21.35 m Maximum width 2.45 m Maximum height (when stowed) 0.55 - 0.84 m Maximum height (with cargo) 6.3 m (PCTC) 6.2 m (RoRo) Greenhofer Technical specifications Maximum payload Maximum cargo length Maximum width Maximum height when stowed Maximum height with cargo Dimensions 15 tons 25 m 2.45 m 0.55 - 0.84 m 6.3 m (PCTC) 6.2 m (RoRo) Air Shuttle trailer and Greenhofer For railcars with bogies attached The Air Shuttle trailer is proof of Wallenius Wilhelmsen’s ingenuity at work. Designed by employees in Bremerhaven, these trailers transport fully assembled railcars or railcar shells with rail bogies attached. The Air Shuttle eliminates the need to lift heavy assembled railcars, trams and subway cars by crane onto rolltrailers for transport. The Greenhofer is a smaller variant of the Air Shuttle and as such, it functions much in the same way. However, because of its lighter construction, the Greenhofer carries a maximum payload of 15 tons while the Air Shuttle can carry loads of up to 47.5 tons. The Air Shuttle and Greenhofer significantly reduce the potential for damage that can result from lifting heavy cargoes that may contain sensitive computer equipment. Railcars simply roll on to and off of the trailers. This process saves time, cuts costs and improves the overall quality of service provided. How it works Fitted with rails on top, the Air Shuttle has a pneumatic system that can lower the trailer bed to ground level. This enables direct transfer of railcars from rail racks to the Air Shuttle trailer via a ramp. Railcars can also be lifted onto the trailer. Horizontal transfer to or from another trailer is also possible. The distance between the frames on which the wheel bogies rest can be adjusted. The Air Shuttle lifts the railcar and frames off of the frame supports and transports the railcar to a stowage location on board. There the trailer is lowered so that the frames again rest on the stanchions. The Air Shuttle is now free to load the next railcar. At the port of discharge the procedures are then reversed. Only two Air Shuttles are required for a major contract, one located in the port of loading, and one in the port of discharge. Equipment 35 Technical specifications Dimensions Maximum number of units 2 per railcar shell Rubber Tyre Bogies For railcar shells Maximum gross weight 45 tons Maximum length Customised Maximum width Customised Maximum height Customised The Rubber Tyre Bogie concept was originally developed for below-deck RoRo service of railcar shells shipped without bogies attached and equipped with air brakes. How it works Each railcar shell requires two Rubber Tyre Bogies, which together can accommodate a load of approximately 45 tons. Wallenius Wilhelmsen customises the bolsters on top of the Rubber Tyre Bogies according to the technical specifications of the railcar shell. The customised bolsters act as the coupling that connects the railcar shell to the Rubber Tyre Bogies. The railcar shell is lifted onto and coupled at each end of the car to the Rubber Tyre Bogies. A railcar shell is lifted only twice, onto Rubber Tyre Bogies when loading and off again when discharging the cargo. A terminal truck tows the Rubber Tyre Bogies with the railcar shell on board. For safe manoeuvring, the bolster on the front bogie remains unlocked to facilitate turning while the bolster on the rear bogie is locked. Stowage Once the railcar shell is on board the vessel, the tow truck is usually disconnected. The rear bolster is then unlocked. Two small forklifts, one at each end of the shell, manoeuvre the railcar into its final stowage position. Both bolsters are then locked to hold the shell securely in place, eliminating the need for lashing the shell. Timber stanchion blocks are placed, both fore and aft, under the bolsters on both sides. The Rubber Tyre Bogies are securely lashed with chains and binders to rings that are welded to the deck of the vessel. At the port of discharge, this operation is reversed. Door-to-door service Door-to-door service can be provided as long as road permits for the bogies have been obtained in the exporting country and in the country of destination. Wallenius Wilhelmsen’s Rubber Tyre Bogies have been granted road permits for use in the United States. This enables the delivery of railcar shells on bogies directly to the factories. Shippers can pick up Rubber Tyre Bogies from the terminal and transport them to their sites. Shippers can also transport railcar shells to the Wallenius Wilhelmsen terminal for mounting by our stevedores. After transport, shippers simply return the empty Rubber Tyre Bogies coupled in pairs to the Wallenius Wilhelmsen terminal. Wallenius Wilhelmsen currently owns approximately 250 Rubber Tyre Bogies.

Bolsters For heavy, bulky cargo Bolsters, or flatbeds, are well suited to ensure damagefree handling of heavy, bulky cargo. This includes cargo such as components, pallets, bales, bundles, reels or crates. Heavy-duty forklift trucks and trailers move and stow the bolsters. Cargo on bolsters is always stowed below deck and may be stacked, depending on the type of cargo. To secure the cargo, web lashings or chains are threaded through the lashing eyes on all four sides of the bolster. For fragile cargo, Wallenius Wilhelmsen places corner protectors under the lashings. Bolsters are secured to the deck of the vessel. On request, shippers can collect bolsters for stuffing. Empty bolsters are transported in bundles of six units per truckload. Consignees can pick up the loaded bolsters at our terminals in the port of discharge for transport to their warehouses. Wallenius Wilhelmsen owns approximately 5,000 bolsters.
