DUC’s new Multi-Purpose Support Vessel ‘Solution’ is perfectly suited for operations such as Buoy Installations, SPM Maintenance, Bathymetric Survey, Soil Investigations, UXO Survey and Clearance, Cable Removal, Debris Removal, Grouting Works and Bubble Curtain Deployment. The vessel is also strong enough for beaching during Cable Projects.
‘Solution’ has a length of 55 metres, a draft of minimum 2.80 metres and maximum 3.50 metres, and a cruising speed of 12 knots. She is diesel-electric powered by a combination of six Volvo Penta D13 diesel engines delivering 475 kW each; two 650 kW electric Omega Verhaar azipods providing aft thrust, and two 450 kW electric thrusters at the bow.
One of the bow thrusters is the swing-up type. The vessel is equipped with a DPII system for superior positioning with an impressive DP-capability plot. At ‘Solution’’s stern, there is a six-metre-wide roller, with the option to install a 50 ton tugger winch. A 20 ton A-frame and two Ø1,20 m moon pools is also included to facilitate survey work.
‘Solution’ can accommodate a sizeable crew, with sleeping arrangements for 42 people and capacity for additional client offices on the vessel’s upper deck. Extra measures have been taken to avoid noise and vibration in the accommodation areas, and all cabins are equipped with TV, internet and air-conditioning.
Time and cost efficient
DUC is committed to helping its customers save time and money. ‘Solution’ is designed to optimise mobilisation and take advantage of the best day rates. Once equipment is on location, a full dive spread can be mobilised in just under six hours, because strongpoints for containers and LARS systems are already in the correct position. The accommodation provision also makes the vessel suitable for 24/7 operations. On DPII, ‘Solution’ has a 25-day endurance, and on 4-point mooring, an endurance of 40 days.
Solution’s heave compensated crane, economical day rate and efficient fuel capability provide attractive advantages for ROV support operations.
Solution’s Ø1,20 m moon pools, general manoeuvrability and extended endurance make it an ideal vessel for survey work. Where smaller vessels may need to seize operations during bad weather and high sea states (over 1 m), ‘Solution’ is designed to keep going. The large survey desk in the bridge or office on the main deck can be used to place equipment and review data or data processing.
