Loading Software for Jack-Ups
Autoload-Jack up version is developed for the specific need for monitoring and simulation of stability and
strength both for free floating (transit) condition as well as jacking up / preloading and elevated conditions.

Key Feature
r s
Handle intact and damage conditions
Handle wind in any direction (360 degrees)
Maxvcg curve and margin bars or direct
stability analysis (or combination)
Compare vessel condition with preset strength
and stability limits
Simulate crane loading and unloading with 3D
crane model
Calculate weight of wire paid out, buoyancy
from submerged cargo
Graphical editing of deck cargo
Booking list
Cargo manifest report with graphical layout of
deck cargo
User controlled Library for standardized
deck cargo
Graphical loading of pipe, including water in
pipe calculations
Calculate Dynamic motion parameters
Perform ballasting sequence
Perform loading / unloading sequence
Perform crane ballast sequence, or any
other sequence
Automatic ballast calculations, based on target floating
position input by user
3D window showing vessel with correct deck load, crane
position / load and vessel floating position
Customizable alert system
Automatic or manual Draft survey, based on draft sensors
or observed drafts at marks. Draft marks and draft sensor
positions are configured in the 3D vessel model and
ensure accurate calculated results, especially if the
vessel is not upright
User-control of sea water density
Connects to onboard tank sensors, draft sensors, winch
tension sensors and any other sensor readings available
in the vessel IAS, such as chain paid out, wind and risers
Correct tank volumes calculated in vessel 3D tanks with
current heel and trim, based on pressure sensor input
from IAS
One license of Autoload for a specific rig can be installed
on unlimited number of computers onboard and onshore,
with exchange of loading data (for emergency response
and redundancy) with no extra cost
Create readily printable reports, can be exported to
Microsoft Word
Additional Features for Jacking and Preloading Mode
Individual leg penetration curves saved for each field
Monitoring of online load / penetration during the preloading phase
Load / save / report / print penetration curves
Additional Features for Elevated Mode
Calculated Spud can load
Measured Spud can load
Max allowable load (set for each field)
Alarm for max allowable Spud can load
Calculate Overturning moment and check against Max allowable
tipping moment
Allows independent sea depth for each leg
Calculate constant (unknown) weight based on measured leg loads
Autoload 3D-viewer
Graphical 3D presentation of crane operation and deck load. Weight crane and hooked load, wire and buoyancy
are accounted for during crane lifts. Monitoring of vessel COG and tipping moment, alarm triggered if exceeded.
Crane online or simulation (planning).
Free Floating Mode
Leg heights can be set either graphically or numerically. Since Autoload immediately updates the floating position
and constantly monitors critical values such as stability and maxvcg a change in leg height will trigger a round of
calculations based on the new leg height and the effect on buoyancy, center of gravity and wind area.

Main screen overview of the vessels status in all operation modes, both free floating and jacked up
Jacking and Elevated Mode
The vessel is considered as semi-floating and in Elevated mode while jacking the vessel is considered not freefloating. In either of these modes a ‘Jack up window’ is used to monitor and simulate all the relevant aspects of
operating the vessel in this way. Additionally, various alarms, such as longitudinal strength and over-pressure of
the foot pads may be configured.
3rd Party Integration
Autoload can either be fully integrated into the vessel control system or receive sensor data via standardized
communication protocols, for tank loads, draft, mooring loads, chain paid out, (chain in lockers), risers, wind or any
vessel load measured with sensors.
When on-line, all sensor data are automatically updated to reflect real conditions. Or the operator can choose to
work off-line to carry out simulations (what if situations).
