Supervisory Control And Data
Acquisition (SCADA)
The operational efficiency and safety of any equipment
depend on a clear and highly reliable user interface.
So Aker Solutions has developed the multiWOCS™
SCADA system.
Designed and built in-house by a dedicated engineering team, the SCADA
system is based on best practices from
the nuclear and power industries and
incorporates years of hands-on operational experience of Aker Solutions’
engineers.
The human machine interface (HMI)
provides a comprehensive overview of
all modes of workover operations in an
uncluttered format that makes irregular
notifications, such as alarms, immediately identifiable.
Full redundancy of subsea control is
achieved through two independent
communication channels. The SCADA
system is constructed from commercially available off-the-shelf components, making it easy to maintain.
A reference laboratory with a replica
SCADA system enables the SCADA
development and test team to conduct
rigorous hardware-in-the-loop (HIL)
testing of the system. Hardware simulators for software development testing
complement the HIL test facility. Automated test routines ensure accurate and
extensive testing of the SCADA system.

riser connector for use on standard and special workover
riser joints.
riserLOCK™ 7.10
riserBIND™
The riserLOCK™ 7.10 system provides a step
change in safety and riser running efficiency.
The riserBIND™ automated connection tool
has been developed to make up and break
out the riserLOCK™ 7.10 workover riser connector. It is designed for remote operation,
giving the driller access to operational data
and information from his chair.
The riserLOCK™ 7.10 workover riser connector is used on standard and special riser
joints. The connector is based on upset pipe
technology. It eliminates the need for welding
and provides optimal fatigue life and recertification performance in open-water and inriser applications.
„„ 7 3/8” bore diameter
„„ 10k working pressure
„„ Non-welded riser
„„ No load bearing threads
„„ Optimized for fatigue capacity
„„ Eliminates manual makeup
„„ Nace (sour service) compliant
A radio control panel is available for contingency operations. This automated tool enables quick make and break, accelerating the
run time and minimizing the risk of injury to
personnel.

The riserLOCK™ Family - Safety Joint
The Aker Solutions safety joint is a newly qualified product,
developed to minimize or prevent the impact of structural
damage and permanent leakage of well barriers caused by
abnormal load conditions.
The safety joint is designed to break off
before any load combination of effective tension, bending moment and internal overpressure exceeds the yield capacity threshold of
the permanent well barriers. It enables safe
and quick disconnection of the riser string in
case of any accidental scenario listed below:
„„ Failure or lockup of riser tensioners or
heave compensator
„„ Dysfunction in mooring line or dynamic
positioning (DP) causing the vessel to
move off location
„„ Loss of stickup and stroke margin causing
stroke-out and high riser tension
In combination with Global Riser Analysis
(GRA), this safety joint has several unique
features which bring significant operational
and HSE improvements:
„„ Increases
operational envelope and
safety margins. The pressure-balanced
design ensures a consistent release load
independent of internal pressure
„„ Limits the impact of recoil energy as the
safety joint releases. In case of safety
joint separation, the water dampers prevent instantaneous strike-out of the riser
and potential hazards to workers and rig
infrastructure.
„„ Ensures safer well control via automatic
initiation of Emergency Shutdown (ESD).
The control system on the Emergency
Disconnect Package (EDP) monitors the
breakaway part of the safety joint and
initiates shutdown of the well barrier elements in case of separation of the breakaway part.
„„ Reduces risk of spillage. Inner and outer
barrels of the safety joint are of telescopic
design and allow sufficient time for closure of well barrier elements and well
containment, preventing leakage of riser
content to sea.
„„ Allows the riser to be run in harsher
weather and environmental conditions
thanks to a strong mode functionality that
temporarily increases joint capacity.

The riserLOCK™ Family - Heave Eliminator
The Aker Solutions heave eliminator is designed to limit the relative
movement between the rig and topside equipment, improving
safety for offshore personnel during rigging and tool building. The
heave eliminator also provides greater flexibility and efficiency as
operations normally performed in the derrick can be carried out on
the drillfloor.
The heave eliminator makes it possible to latch
onto the marine riser telescopic joint and to latch/
unlatch the workover riser inside. When unlatched,
the telescopic joint is free to move and hence eliminates much of the relative vertical movement of the
Surface Flow Tree (SFT).
Features and benefits:
„„ Enlarges the operational window when rigging
tool strings to 4 meters heave and beyond
„„ Reduces the need for work at height on top
of the SFT and Coiled Tubing Tension Frame
(CTTF), as the entire intervention tool string can
be built in advance on the drillfloor while all the
intervention equipment, SFT and landing joint
are not connected with the rest of the riser system
„„ Obviates the need for a tension joint and a tension ring adapter as it is replaced with a heave
eliminator, which latches onto the base of the
marine riser telescopic joint.
„„ Utilizes the drilling riser telescopic joint, flex
joint and diverter system already existing on the
rig
„„ Avoids positioning high-loaded joints in rotary
during storm hang-off as the riser system can
hang off in the flex joint by disconnecting the
HP riser from the HP latch
„„ Enables easier and quicker repair or replacement of the seals compared with other heave
eliminator solutions
Main system components:
„„ High-pressure (HP) latch - A ’dog type’ con-
nector which enables the landing, latching and
sealing of the HP sleeve
„„ HP sleeve - An assembly of standard workover
riser pipe with the SFT on top and an interface
to the HP latch at the bottom
„„ Transition/cross-over to a marine riser telescopic joint
