Cargo-handling operation is carried out at the cargo-handling room located in front of the accommodation quarters, where the Kawasaki IMCS (integrated
Management Control System) is installed for monitoring and controlling the cargo handling operation as well as monitoring engine conditions. The
Kawasaki IMCS is very easy to use since it was developed by incorporating experience and suggestions from many operators.
The 145,700 cu. m. Liquefied
Natural Gas (LNG) Carrier LNG
Enugu, which Bergesen DY ASA ordered to DSME for the world-wide transporting LNG, is registered in
Bermuda and was delivered on October 28, 2005. The ship is designed and con- structed to meet the requirement of
Lloyd's Register (LR) with the class notation +100A1, Liquefied Gas Tanker,
Ship type 2G, Methane in Membrane tanks, Maximum vapor pressure 0.25 bar, Minimum temperature -163 oC,
ShipRight (SDA) *IWS, LI, +LMC,
UMS. NAV1, IBS with descriptive notes "Pt. Higher Tensile, ETA,
ShipRight (FDA, CM, BWMP(S),
SCM, TCM). LNG Enugu has a contin- uous upper-deck with aft sunken deck, a raked stem with bulbous bow, a bow thruster, a semi-balanced rudder and fixed pitch propeller driven by marine steam turbine. Four cargo tanks are designed as GTT membrane type (GT
No 96 E-2 system) and are designed to keep the LNG at -163 oC under the con- dition of maximum daily boil-off rate less than 0.15% of fully loaded cargo volume. Primary/secondary barriers of 36 percent nickel-steel alloy (Invar, 0.7mm thickness), which have a low thermal expansion coefficient, are installed in cargo tanks and plywood boxes filled with expanded perlite are used for the primary/secondary insula- tion.
Through the cargo tank length, under- deck passageways are arranged port and starboard in trunk space and also center passageway (pipe duct) with trolley sys- tem is arranged in the double bottom.
These passages are used as pipe & cable passages and for inspection/mainte- nance. A six-tier deckhouse located aft provides accommodation for 40, includ- ing Suez crews. The vibration levels in living areas are designed especially low at normal operating condition.
Cargo handling systems are designed to be capable of loading or discharging the LNG using eight cargo pumps with capacity of 1,650 cu. m./h and four stripping/spray pumps.
Liquefied cargo handling equipments such as two sets of main cargo pumps, one set of spray/stripping pump, one set of capacitance type level gauge includ- ing back-up capacitance type top/bot- tom sensor and one set of float type level gauge are fitted in tripod mast con- struction which forms a complete assembly unit per cargo tank by incor- porating all outfittings and piping in cargo tanks. Vapor cargo handling equipments such as two high duty com- pressors, two low duty compressors, one main vaporizer, one forcing vaporizer and two boil-off/warm-up heater are arranged in cargo machinery room which is effectively arranged so as to be readily accessible, easy operation and maintenance.
The main propulsion unit is a Cross compound steam turbine (MCR: 33,700
PS x 86 RPM) with high pressure tur- " D D V S B U F 5 I J D L O F T T .
