Annual

Halter Marine To Build Anchor Handling/Towing Supply Vessels For Seacoi

NIGHTSIGHT,

C-MAP are major suppliers of digital nautical charts, a crucial element in the improvement of safety of navigation at sea.

The C-MAP digital chart library which includes over 3000 digital copies of original paper charts is being continually expanded. The CM93 data format fully conforms to IMO's S57/DX90 specification and as authorised digital charts data become available it will be possible for these to be incorporated in C-MAP's database.

A number of major marine electronics manufacturers have selected C-MAP CM93 digital charts for their ECDIS systems. If you are planning to invest in safety and efficiency by installing an ECDIS system, contact your system supplier or call us to check that your system can use C-MAP's unique database.

Each vessel will be equipped wi a Furuno GPS and a Robertsc

DPS. Maneuverability and static keeping will be aided by a pair (

SMI, 800-hp bowthrusters, an one SMI, 800-hp stern thruster.

Anchor handling equipment wil include a Smatco double drun winch with 500 tons, or one million pounds of pull per drum. The ves- sels will also be equipped with

Triplex shark jaws, chain lockers with 18,000-cu.-ft. of storage space and two wire storage reels.

Electrical power will be generat- ed by two 2,000-kW, gear-driven generators or a 400-kW generator driven by a Caterpillar 3508 diesel with 190 kW of emergency power generated by a Caterpillar 3306B diesel. Each vessel will be outfit- ted with a Skum fire monitor with 2,600-gpm capacity, expandable to 10,600 gpm.

Halter Marine signed a contract worth approximately $45 million for the construction of two, 255-ft. (77.7 m), 14,000-bhp anchor han- dling/towing supply vessels (AH/TS). The 14,000 bhp will be produced by four GM EMD 16-645-

F7B diesel engines driving Berg

CP propellers in Kort-type nozzles through Reintjes compound reverse/reduction gears. This con- figuration is designed to ensure a bollard pull of approximately 160 metric tons.

The compound gears give the captain the flexibility to disengage two of the four engines for greater fuel economy. The boats' 2,000-kW
