Yard: Hanjin Heavy Industries

Ship: Hanjin Pyeong Taek

Type: LNG Carrier

Owner: Hanjin Shipping Co. Ltd.

The 130,600-cu.-m. Hanjin Pyeong Taek is reportedly Asia's first LNG carrier with a GT membrane type containment system. The ves- sel was built by Hanjin Heavy Industries for the purpose of importing liquefied natural gas (LNG) from Indonesia for the Korea Gas Corp.

With the Gaz Transport (GT) containment sys- tem, liquid natural gas is carried at -163 degrees Celsius and atmospheric pressure in a tank made of a thin membrane in the form of metallic sheets, which are constructed of a 36 percent nickel alloy in thicknesses of .7 mm (Invar). The coefficient of thermal expansion for the Invar is very low, therefore high thermal stresses do not occur in the membranes.

The insulation layer of the GT system is com- prised of plywood boxes containing expanded perlite. This system is designed to sustain the liquid pressure, static and dynamic loads, and to keep the low daily boil-off rate of 0.15 percent of the total cargo volume.

Within each tank, the pumps and filling line are arranged on a tripod mast. Cargo loading is carried out by shore pumps, and vapor produced in this process is returned to shore by the ship's high duty compressors. Cargo unloading is car- ried out by two Ebara electric, submerged cargo pumps, located at the bottom of each tank.

The Centralized Administration and Control

Center (CACC/provides a central command sta- tion for cargo,and ballasting operation, as well as monitoring, remote control of the propulsion plant, integrated automation and shipboard man- agement systems.

The ves/el is outfitted with two entirely sepa- rate TDC 3000 Basic systems from Yamatake-

Honeywell, one for cargo/ballast operations, the other for machinery/electric generation

The total navigation systems (TNS) were inte- grated by Mitsubishi and Atlas Elektronik.

Mitsubishi supplied a TNS, Atlas Elektronik sup- plied three 960 radars, a 9600 S-band ARPA, a 9600 X-band ARPA, an Echograph 481 echosounder and a DOLOC 23 doppler sonar & docking system. Full GMDSS communication equipment was supplied by JRC. The ship also offers Sea-Tel's satellite television reception system. innovato

The CS Cable Innovator is the world's largest purpose built cable ship. With a gross tonnage^ of 14,000 tons and a deadweight of 9,4( tons, the ship has an overall length of 477i (145.4 m), a breadth of 79 ft. (24 m) and a < of 28 ft. (8.5 m). This new generation ofytable \yin0 ship was developed especially for the ng fiber optic submarine cable market. It is intended for world-wide trans-ocean cable lay- ing. The vessel features a fully stern-working ncept, designed to enhance operational per- ormance. The propulsion is arranged through a diesel-electric plant. The ^hip is fitted with a dynamic positioning system/VThere is accom- modation provided for up to 80 chuv and cable representatives, all in single berths.

Crew cabins, including a gymnasium and two recreation rooms, are arranged on the main deck amidships and forward. Aft of this area on the main deck is the machinery control room work- shops, the cable drum, the central store and cable equipment holds.

The ship's control center, a combined wheel- house/operations control room, is located on the navigation bridge deck above the bridge deck.

This combination is a new and improved feature.

The ship is equipped with a dynamic position- ing/joystick control system including taut wires, acoustic and Differential GPS connection. The dynamic positioning system, type DPS901, is ipplied by Cegelec.

The Cable Innovator has a diesel-electric power station machinery with five diesel-genera- tors supplying the common busbar. The marine diesel-generators consists of three Wartsila

Vasa 9R32E/3,645 engines, each driving a 4,160-kVA/60Hz ABB Marine AC generator.

The ship has two 2,700-kW (0-1,000 rpm) ABB propulsion motors which are driving a KaMeWA fixed pitch propeller in a steerable nozzle through a twin input, single output Valmet reduc- tion gear. Four electrically driven thrusters are installed for ease of maneuverability.

The ship is designed to allow lay of all types of submarine communication cables and associ- ated repeaters, regenerators, equalizers and joints. Onboard the ship there are two cable lies, one 13.1 ft. (4 m) diameter electrical cable drum and one 21 wheel pair linear cable engine.
