Ulstein Sea of Solutions develops new derrick pipelay vessel

Abu Dhabi based National Petroleum Construction Company Ltd. (NPCC) has awarded Dutch design office Ulstein Sea of Solutions the basic design contract for their new large derrick pipelay vessel DLS-4200.

The new vessel (loa 196.9m, beam 43.4m) will be one of the biggest vessels of its kind, combining S-lay double joints pipelay operations with 4,200 sT lifting capacity.
The design of the vessel is a modified version of the SOC 3000 design of Ulstein Sea of Solutions (USOS) and will be equipped with an Amclyde Model 80 crane.
DLS-4200 will be designed to operate worldwide, but will initially be equipped with a mooring system to operate in the Arabian Gulf and India. However, a future DP2 upgrade is envisaged and catered for in the design to minimise the technical impact in the future.
