Hyundai Heavy Industries Co., Ltd. (HHI) delivered a 177,000 cu. m. Tri-

Fuel Diesel Electric LNG carrier, the At- lantic Max LNG carrier that permits ac- cess to the majority of Atlantic terminals, to Mitsui Osk Lines (MOL) on Japan in

February 27, 2010. Abdelkader is 298 m long, 46 m wide and 26.8 m depth with a designed draft of 11.9 m. Equipped with four Mark membrane cargo tanks, the vessel is designed and constructed as a type 2G ship specified in IGC code, suit- able for carrying LNG of which vapor pressures are within the range from at- mospheric pressure to 0.25 bar g. The vessel has continuous deck with trunk/without forecastle and to have a bulbous bow, lowered mooring deck, transom stern, open water type stern frame, single screw propeller driven by two electric motors. Tank insulation is of

GTT Mark system which has a 270mm thick to satisfy the low boil off rate of 0.15 % by volume of the total cargo per day. A shore manifold is provided on each side of the upper deck between

No.2 liquid dome and No. 3 vapor dome.

A compressor room is arranged in the area in way of No. 4 tank. The cargo dis- charging is performed by pumps in tank having each capacity of 1,750 cu. m./hr.

The supplementary gas during discharg- ing is coming from shore or produced by onboard LNG vaporizer to maintain cargo tank pressure. An emergency cargo pump is used when cargo pump in tank is failed.

One LD compressor and one spray pump as fuel pump is running to supply fuel gas to the engine room under normal sea going condition. The main propulsion machinery of vessel has four sets of main tri-fuel engines, two 50% reversible syn- chronous motors (each with power con- verter and associated transformers, control and excitation system), including one reduction gear (twin input/single out- put) with one propulsion shaft/propeller.

The vessel has redundancy that failure of any motor drive auxiliary system shall not result in a total loss of propulsion motor.

The propulsion system is tri-fuel diesel electric, capable of burning a fuel gas (natural boil off gas (NBOG) and/or forced boil off gas (FBOG)) or Maine

Diesel Oil or Heavy Fuel Oil. The power generating plant utilizes all available

NBOG and makes up the required power by burning additional Heavy fuel oil or

Marine diesel oil or FBOG. Main diesel engines are fitted with exhaust gas econ- omizers as waste heat recovery system.

A gas combustion unit is provided for pe- riods when natural boil off gas (NBOG) cannot be burned in the tri-fuel diesel en- gines or when NBOG consumption is low and the cargo tank pressure rises. A fuel oil supply unit is provided for flexi- ble operation of each Tri-fuel diesel en- gine.nThe Tri-fuel diesel engines are to be fully compliant with MARPOL

Annex VI regulation 13 and the NOx

Technical code. The machinery or engine control room and the cargo control room contain all facilities to permit centralized operation of the plant and equipment and allow unattended operation of the ma- chinery plant under all operation modes.

The control console containing IAS (In- tegrated Automatic System) which is de- signed and implemented as to ensure a high level of fault tolerance such that the single failure of any component, power supply or device not to prevent normal system operation, nor compromise the integrity of the system. Besides, a Cargo

Control Room (C.C.R) which is arranged in the accommodation deck allows the centralized control of loading, discharg- ing, ballasting, de-ballasting and contin- uous monitoring and control of the cargo handling system including LD & HD compressors.

FEATURE GREAT SHIPS 2010

E.R. Brandenburg

The 180,000 DWT Bulk Carrier E.R.

Brandenburg built at Hyundai Heavy

Industries Co., Ltd. (HHI) was deliv- ered to E.R. Schiffahrt, Germany on

March 3, 2010. The ship has one con- tinuous freeboard deck from stem to stern with f’cle deck, in way of the cargo space. Special attention has been paid to the ship's maneuverability re- sulting in a large rudder being fitted.

It is designed to carry coal and ore cargos. The ship to have nine cargo holds and water ballast tanks at double bottom, top side and peak tanks. No. 1, 3, 5, 7, and 9 cargo hold to be designed for ore cargo loading.

No.6 cargo hold may be used as water ballast tank for ballast voyage under heavy weather. The vessel is, among others, equipped with the highly advanced navigation system such as ECDIS for collision and grounding avoidance and navigation monitoring. The vessel has an overall length of 292m, width of 45m and depth of 24.7m with a design draft of 16.5m. It is powered by a Hyundai-

B&W 6S70MC-C7 main engine with an MCR output of 18,660kW at 91 rpm, enabling it to sail at a service speed of 15.4 knots. Electric power is supplied by three main diesel genera- tors with an output of 730 kW and one 130 kW emergency generator.

The ship is classed by DNV +1A1,

Bulk Carrier, ESP, ES(S), CSR, BC-A (Holds 2,4,6 and 8 may be empty),
