Ulstein offers Capex-friendly shallow water work horse

Ulstein has introduced a dynamically positioned multipurpose construction vessel suitable for shallow water operations.

It says the main driver for the new 115.4 m x 30.8 m S182 design was to develop a "very CAPEX friendly" DP vessel with good capabilities to support various offshore operations, including cable lay and offshore construction.

The result is described as "a very versatile workhorse" that is capable of shallow water DP operations (at 4.5m draft) including beaching.

The design features a large open work deck that can accommodate up to 30 m ø carousel, a large cargo hold below deck and approximately 10,000 DWT capacity. A main offshore crane of up to 400 t can be located in the side of the vessel, while a passage way below main deck between the aft casings and accommodations avoids people having to cross the open work deck.

The vessel is capable of supporting a wide variety of operations:

Cable laying
