GREAT SHIPS OF 1998

Hyundai's Front Century (Continued from page 49) approach to structural needs, promises long-term gains in main- tenance needs and ship integrity.

Front Century and the second

VLCC in the series are classed with Lloyd's Register, and the whole array of notations conferred includes ShipRight procedures as regards structural design assess- ment (SDA), fatigue design assess- ment (FDA) and construction mon- itoring (CM). The ensuing three C- generation ships are being built to

Det Norske Veritas' class require- ments, including CSA-1 structural strength and fatigue strength notations.

Subdivision of the revenue- earning section of the hull by lon- gitudinal and transverse bulk- heads is such that Front Century offers a loading capacity of 350,060 cu. m. in five center cargo tanks, five pairs of side cargo tanks, plus

The intra-hull spaces, used throughout to provide much of the enormous water ballast capacity required by such a vessel, are dimensioned to Marpol-dictated criteria, giving a width of 11.5 ft. (3.5 m) in the wings and a 9.8 ft. (3 m) height in the double bottom.

A maximum outturn rate of 15,000-cu. m. per hour is offered by three steam turbine-driven verti- cal, centrifugal cargo pumps, and loading can be achieved at up to approximately 20,500-cu. m. per hour through the central manifold.

Three grades of oil can be handled simultaneously with two-valve segregation, and ullaging of the cargo tanks is undertaken using a

Saab tank radar level gauge sys- tem.

Fixed monitoring equipment detects any hydrocarbon gas released in the pump room and ballast spaces. The strong posi- tion of the MAN B&W marque in the Korean shipbuilding two- stroke engine stakes is reflected in the adoption in the Frontline

VLCC of the seven-cylinder

S80MC diesel, one of the most pop- ular choices for large crude carrier propulsion. Manufactured at

HHI's engine works on the ship- yard estate, the unit offers a maxi- mum continuous output of 34,650- bhp (25,485-kW) at a slow-turning 79 rpm. The installation provides scope for a service speed of up to 15.7 knots in fine weather.

Electrical power is derived from three gensets based on Wartsila 8L20 diesels rated at 1,414-bhp at 720 rpm, while steam require- ments are met by two Mitsubishi marine boilers and a Kang Rim exhaust gas economizer.

Indicative of the level of automa- tion incorporated in the new breed of Frontline VLCCs is the adoption of an advanced cargo handling and planning system called Super

Cargo, which is supportive of one- man operations, and a machinery predictive diagnosis and mainte- nance tool known as Super plant.

The latter uses sophisticated arti- ficial intelligence (AI) and data acquisition techniques.
