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.
