Multi-purpose dry cargo vessel INNOGY SPRITE

According to HSB International September 2002

The 19,300 dwt vessel was completed by Damen Shipyards and delivered to Carisbrooke Shipping Limited in 2003. In the world today flexibility is the key factor, therefore vessel is entirely fitted to carry containers, bulk fertilizers, dangerous goods, steel and paper cargoes. Cointainer capacity is 1232TEU: 530 TEU in holds with stack loads 100t/TEU and 130t/FEU, and 702TEU on deck with stack loads 50t/TEU and 65t/FEU.

The vessel is provided with three Liebherr cylinder-luffing cranes 60t/18m, 40t/32m. She has two box holds; the Hold No1 with a length of 37.68m and the Hold No2 of 72.84. The width of both holds is 20.20m and their height under the hatch covers is 12.28m. The holds are ventilated mechanically with a capacity of 12 air changes per hour. The tanktop is strengthened generally to 15t/m2 and maximum up to 20t/m2 according to loading pattern. Six tiers of lashing eyes are fitted flush with the cargo hold side platings.

Both holds are closed by MacGREGOR high stowing folding type hatch covers, operated by means of external hydraulic cylinders. A pontoon type hatch panel, operated by the deck cranes, is placed between the forward and aft folding panels closing the Hold No 2. The holds are provided with lift-away steel pontoons forming non-weatertight tweendeck (uniform load 5t/m2). Pontoons can be locked in two positions. They can be used as grain bulkheads.

A Framo anti-heeling system is fitted in between the cargo holds. The system automatically provides compensation of angles due to cargo handling with the deck cranes. The system features 1120m3/h reversible propeller pump operating in both directions by reversing the electric motor. In case of heavy cargo handling, pre-heeling can also be carried out.

The prime mover consists of a two-stroke engine rated 7860kW driving a 5.10m diameter four-blade CP propeller. Service speed of 14.9 kt on 30t HFO (IFO 380).

A 1500kW shaft alternator of 1875kVA, 400VAC, 50Hz is driven by a tunnel gear-based power take-off. A highly elastic torsionally Vulkan Rato-S flexible rubber shaft coupling is fitted between the diesel engine and the tunnel gearbox. Furthermore, two generator sets are installed, each consisting of an ABC diesel engine and A. van Kaick generator, output 820 kVA, 400 VAC, 50Hz. A harbour/emergency generator set of 330 kVA is installed on the boatdeck.
