MARCH 25, 2014 — Shipyard De Hoop, which has shipyards in Lobith and Foxhol in the Netherlands,has won an order to design and construct a 68.23 m x 15. 77 m offshore service/support vessel ANL (Awaritse Nigeria Limited).
Designed to operate in the Royal Dutch Shell (Shell Nigeria) and Chevron oil fields offshore Nigeria, the OSV will be deployed for the discharge of Transmix liquids, a by-product of oil-production and oil-transport through pipe lines.
The delivery of the OSV is scheduled for the last quarter of this year. De Hoop this will be able to deliver the vessel within this time frame thanks to its experience with this type of work vessel. It says that customizing proven concepts and keeping things simple is the secret behind the straight forward design, which is competitive in overall costs (investment and running costs) and operational reliability.
ANL has chosen a diesel-electric propulsion concept for the vessel to achieve enhanced flexibility and economical superiority. The hull shape is based on a proven De Hoop design with excellent DP capabilities. The generators are located on the main deck, which not only allows much larger cargo volumes, but also easier access for maintenance.
Providing accommodations for a total of 30 persons, the DP2 class vessel has a cargo tank capacity of 800 cu.m and 500 sq. m of deck cargo space. Deadweight capacity is 2,600tons.
To provide ample cargo pump capacity, there are two pump rooms: one in the aft ship (forward of the thruster room) and one in the forward area, just aft of the bow thrusters. The combination of pumps provides a Transmix transfer capacity of 1,000 barrels per hour. For hose handling and loading or unloading deck cargo, two knuckle boom cranes are fitted: one on starboard side aft and one on portside amidships both with a capacity of 10 tons at a maximum outreach of 15 m.
While its primary role will be the transportation of Intermix/Transmix liquids, the vessel will also be suitable for oil recovery and a vast range of offshore inspection, maintenance and repair work, taking advantage of its cranes and large work deck area.
