Saudi Arabia-based marine services provider Zamil Offshore Services has contracted Dutch naval architecture firm Conoship International to design a 76.2-metre dive support vessel (DSV) with a maximum draught of 2.5 metres for shallow-water operations in the Persian Gulf region.
The project scope covers the concept and basic design, with the engineering package intended for subsequent yard selection and construction.
The vessel is intended to assist with maintenance of subsea infrastructure as well as offshore oil and gas operations.
The DSV will have a beam of 17 metres, a deadweight of about 950, and accommodation for 76 people.
For station keeping, the vessel will rely on a DP2 system, two azimuthing thrusters and twin spud poles. The poles will provide an alternative positioning method for shallow-water work, while the propulsion specification includes a diesel-electric arrangement for DP operations.
The 360-square-metre reinforced working deck will be used to carry heavy cargo. Offshore work will be supported by a knuckle boom crane with a 22-metre reach and a lifting capacity of 20 tonnes.
A dedicated diving deck and control room will accommodate a launch and recovery system, a remotely operated vehicle, and other dive support equipment. Five dry bulk tanks are intended to carry supplies to offshore operations.
The DSV will be designed to comply with American Bureau of Shipping class rules and the Special Purpose Ships Code. Conoship’s design approach will include a lightweight structure, optimised hull lines, stability work, and resistance reduction.
