ATLAS RADARS and TANKERS...

BSRA Receives Support For

Research Into Quieter Ships

Against a background of increasing con- cern for the seafarer from the disturbing and sometimes harmful effects of noise, the

Ship and Marine Technology Requirements

Board has given its support to a Shipboard

Noise Project proposed by the British Ship

Research Association.

The project is aimed at improving proce- dures for predicting noise levels in ships at the drawing board stage. It will be concerned in particular with accommodation spaces, and extensive tests and trials onboard ships are planned by BSRA. A full-scale model of an accommodation space will be built to al- low measurements under controlled condi- tions to be made on various materials and for various cabin arrangements.

The move follows the successful comple- tion of an earlier three-year project begun in 1975. As in the previous project, total funding will be provided by the Department of Industry.

The Department of Trade has recently published a Code of Practice for Noise Levels in Ships, and has taken an active and sup- porting interest in both of the BSRA proj- ects. In the introduction to the Code, the point is made that the technology necessary to ensure that every vessel meets its re- quirements is still in the course of devel- opment. It is with this technology that the

British Ship Research Association projects are directly concerned.

ATLAS 6500 BCA lengths (25kW for X-Band, 30kW for S-Band) and rugged narrow beam antennas (.8° for X-Band, 1.7° for S-Band). 16 inch display includes nine ranges from .3nm to 72 nm, "ships head-up" or "North-up" presentation and gyro driven True

Bearing Scale.

All readouts and important control settings are conveniently displayed on an Information Panel around the PPI.

The ATLAS 6500 BCA comprises a complete advanced radar system loaded with all neces- sary features — there are no extras or options available. (A lot of Captains feel that way)

Here's why:

The ATLAS 6500 BCA protects against "sud- den surprises off the starboard bow" through early target detection with Dual Guard Zones.

Plotting is made easy by paralax free flat re- flection plotter, digital 10 minute plot clock and

Speed/Time/Distance table. Precise and fast range and bearing measurements displayed on digital readouts make careful target evaluation simple. Threatening target is kept under surveil- lance by gyro-stabilized electronic marker.

Exceptional picture presentation and target discrimination are achieved by advanced power- ful solid state transmitters with four pulse

Halter Crewboats Delivered

For Indonesian Operations

Halter Marine, Inc., New Orleans, La., has delivered three 65-foot all-aluminum crew- boats to Billiton Metals, The Hague, Nether- lands. Billiton, a subsidiary of the Shell Oil

Company, will operate the vessels in Indo- nesian waters in support of tin mining oper- ations.

Each of the three new vessels, powered by two GM 12V71TI diesels, will operate in Indonesian waters.

The new vessels, PB1, PB2 and PB3, have overall dimensions of 65 feet in length, with a 17-foot beam.

Propulsion in each vessel is provided by two GM 12V71TI diesel engines, and reverse/ reduction gears are MG514 with a 2:1 ratio.

Controls are by Morse.

Auxiliary machinery includes a 20-kw Del- co main generator, a Conselect switchboard, and three tons of Barmar air-conditioning.

Communications and navigation equipment includes a Sailor VHF RT 144 AB, a Scien- tific Radio MD210 single-sideband radio, and

Decca 110 radar.

The 36-passenger-capacity vessels are

Lloyd's classed, 100A launch. They were built at the Chalmette, La., Division of Halter

Marine, Inc., one of 10 shipyards owned and operated by Halter in the Southeastern

United States.

Halter is the world's largest builder of supply vessels for the offshore oil and gas industry.

RECHRISTENED—Rechristening of Matson

Navigation Company's newly renamed S/S

Manulani (ex-Hawaiian Progress) is per- formed by the Reverend Abraham Akaka in

Honolulu. Assisting in the traditional Ha- waiian ceremonies are, left to right: Gilbert

E. Cox, president of Alexander & Baldwin,

Inc., Matson's parent company; Capt. George

B. Cardew, master of the Manulani, and R.J.

Pfeiffer, Matson's president. The Manulani's sistership, the S/S Manukai (ex-Hawaiian

Enterprise) was rechristened on Septem- ber 27. 12 Maritime Reporter/Engineering News
