Product catalog summary

General Description: The DLV 4200 is a self-propelled derrick lay vessel developed by Ulstein Sea of Solutions BV. It is designed for offshore operations, offering a combination of ship design packages and solutions for various vessel types. The vessel is associated with quality and innovation, reflecting the Ulstein brand's long-standing reputation since 1917.

General Specifications: The DLV 4200 is a derrick lay vessel with a transit speed of 13 knots. It features a 10-point mooring system and an optional DP3 class positioning system. The main propulsion consists of two 5500 kW engines, with additional retractable azimuthing thrusters and a tunnel thruster. The main crane is an AmClyde Model 80 with a lifting capacity of 4200 sT fixed over the stern and 2680 mT fully revolving.

Principal Dimensions: The vessel measures 196.9 meters in length overall, with a beam of 43.4 meters and a moulded depth of 19.6 meters. It has a design draft of 7.5 meters and a main deck area of approximately 3,000 m2. The accommodation capacity is for 350 persons.

Pipelay Equipment: The vessel is equipped with three 125-ton tensioners, a 400-ton A&R winch, and various welding and dope stations. It includes a comprehensive pipelay system with redundancy to ensure continuous operations. The S-lay pipelay system features a center double joint firing line and double joint fabrication areas, providing a clean and dry environment for pipelay equipment.

Operational Features: The DLV 4200 is designed for efficiency and cost-effectiveness, capable of operating in water depths up to 150 meters using its mooring system and in deeper waters with its DP system. The vessel's layout ensures that pipelaying operations are not affected by vertical motions due to roll, optimizing performance.
