Shipyard De Hoop wins African vessel dealYard News // March 26, 2014
Shipyard De Hoop in the Netherlands has secured an order for the design and construction of what it describes as an "intermix/transmix vessel."
The contract is for a newly-designed 68.23 x 15.77m offshore support vessels for Awaritse Nigeria Limited (ANL).
Designed to operate in oilfields operated by Shell Nigeria and Chevron offshore Nigeria, the vessel will be deployed for the discharge of Transmix liquids, a by-product of oil-production and oil-transport through pipelines. Delivery of the vessel is scheduled for the last quarter of 2014.
ANL chose a diesel-electric propulsion concept to achieve enhanced flexibility and economical operation. 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. "The resulting impressive tank capacities make this vessel stand out in its size range," said De Hoop.
Providing accommodation for a total of 30 persons, the DP2 class vessel has a cargo tank capacity of 800m3 and space for 500m2 of deck mounted cargo. With a beam of almost 15.8m the vessel has a deadweight of 2,600 tonnes.
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 knuckleboom cranes are fitted: one on starboard side aft and one on portside amidships both with a capacity of 10 tonnes at a maximum outreach of 15m.
