MOTION COMPENSATED FEATURES Motion compensated cable lay can extend the weather window far The Touch Down Point (TDP) of the cable on the seabed can beyond the operational limits of conventional cable laying vessels. shift over a large distance, which can cause damage to the cable, especially when the lay trajectory is following a bend. In that case the cable is dragged laterally over a large distance ¡ Weather window can be extended by approximately 50% and can snag around obstacles. Variations in cable tension can more operational days ¡ Motion compensated cable lay reduces the risk of cable...

D CABLE LAY FULLY MECHANIZED QUADRANT HANDLING QUADRANT CURSOR SYSTEM The quadrant is fully restrained from the start of the operation The quadrant handling system is equipped with a cursor until it is released below the splash zone system. The quadrant motions are fully restrained until deployed ¡ Increased weather window beneath the splash zone ¡ Controlled and time efficient operation ¡ The cursor system avoids damage to the quadrant ¡ Increased safety ¡ Reduced catenary dynamics MODULAR DESIGN, SHORT MOBILIZATION TIME The system can be installed swiftly because of its modular design and simple...

MOTION COMPENSATED FEATURES ADJUSTABLE QUADRANT RADIUS CONTROLLED TOUCH DOWN POINT LOCATION The radius of the quadrant can be adjusted from the MBR to Motion compensation keeps the touch down point of the cable straight during lowering within a smaller target box ¡ Cable can be abandoned without uncontrolled drop onto ¡ A smaller target lane requires less survey and target lane the seabed. Cable tension is controlled during the complete operation ¡ Quadrant can be retrieved when cable is straight on the seabed avoiding torque variations that can cause cable failure clearing activities ¡ Dragging...

D CABLE LAY REDUCED RISK OF CABLE FAILURE DURING EFFICIENT CPS STORAGE SYSTEM CPS strings are loaded on board in containers and transferred Motion compensated cable lay reduces the tension variations to the firing line using a gutter system in the laid cable to a narrow bandwidth ¡ Containers allow for easy transport and loading facilitating trenching ¡ Height adjustable ramp to extract a CPS from different elevations ¡ CPS gutter system independent of cable routing, allowing parallel operations ¡ Safe access for personnel to containers General Maximum line pull including dynamics Minimum product...
