Great Ships of 2004

Ship Name Almarona

Ship Type LPG

Ship Owner Qatar Shipping

Ship Builder STX Shipbuilding

STX Shipbuilding officially broke into the LPG Tanker market with the deliver of Almarona, the first of two Vessels to

Qatar Shipping, in May. This new opti- mized LPG Tanker has three pairs of cargo tanks and each cargo tank has two deepwell cargo pumps with the capacity to discharge the cargo in approximately 13 hours based on 98 percent of tank volume and density of 0.97 ton/cu. m., and cargo pump (6 sets x 350 cu. m./hr.) and ballast pump (2 sets x 600 cu. m./hr.) are fitted.

Almarona is designed primarily to carry the fully refrigerated liquefied gases into the tanks that are designed for a maximum density of 0.97 t/cu. m., a maximum vapor pressure of 0.25 bar and lowest temperature of -48oC.

The STX-MAN B&W 6S50MC (MK6) installed in engine room devel- oping 12,900 bhp full power at 127 rpm is intended to burn fuel of 380 cSt at 50oC.

This engine, which is well matched with STX designed propeller, produced a sea trial speed of 17.04 knots, 0.5 knots higher than guaranteed.

Free and forced vibration analyses were performed using a 3-D finite ele- ment model to investigate all the possi- ble vibrations of the vessel. And the global vibration measurement during the sea trial was done in accordance to the stepwise RPM sweeping method as rec- ommended in ISO 4867.

The electrical supply derived from three sets of main diesel generator pro- duces 900 kW at 900 rpm each and one oil-fired composite boiler supplies

Ship Name Bilbao Knutsen

Ship Type LNG

Ship Owner Knutsen OAS/Repsol YPF

Ship Builder Izar Sestao

Izar Sestao delivered Bilbao Knutsen to Knutsen OAS, which will operate it for Repsol YPF. The ship has an LNG capacity of 138,000 cu. m. and it is the second ship with these characteristics built by the yard, following the FOC Inigo

Tapias. The burgeoning gas carrier segment is a key market for

Izar, which has ample technical and industrial capacity in

Sestao and Puerto Real. There are two more LNGs under con- struction at Izar's Puerto Real shipyard. Bilbao Knutsen was launched in September 2002. The ship underwent sea trials in

November and the gas trials in December, which consisted on the cooling, loading and unloading of the tanks. For this pur- pose 5,000 cu. m. of LNG from Bahia de Bizcaia were used.

Propulsion28,000 kW at 83 rpm generated by one Kawasaki-IZAR steam turbine, pro- vided by IZAR's Turbine Factory. This factory, located in Ferrol, has also provided the condenser of the propulsion plant. steam. The wheelhouse is equipped with a console incorporating navigation, con- trol and alarm system. Cargo loading is monitored to ensure the ship's condition is within strength and stability criteria limits.

Accommodation is provided for a complement of 18 officers and six crew, plus six Suez crew in the aft superstruc- ture with one set of gravity type lifeboat handled by fixed electric motor driven lifeboat winch.
