The research complex on the RRS

James Clark Ross comprises nearly 400 square meters of wet, dry and environmentally controlled labora- tories, workshops, cool and cold rooms, computer and data prepara- tion suite, underway instrumenta- tion and control room and confer- ence/library facilities.

The cargo facilities consist of two holds capable of carrying 1,800 cu- bic meters of general cargo, as well as bulk aviation fuel and cargo die- sel fuel tanks.

The propulsion system is diesel electric, based on the "power-house" principle comprising four Wartsila

Vasa engines, two 8R32E models and a pair of 6R22/26 units, gener- ating a total of 11,800 bhp at 160 rpm. This system provides the nec- essary power to permit the ship to break level ice up to 800 mm thick at a constant speed of 2 knots.

The centerpiece of the navigation equipment is a SeaNet fully inte- grated system supplied by Sperry

Marine, which includes navigation and voyage management worksta- tions, two Rascar touch-screen con- trolled ARPAs, a pair of interlinked

MK 37 gyrocompasses, an

Aquaprobe MK 5 electronic log, and an SRD-421S dual-axis doppler log.

A Trimble 4000 GPS receiver and a 501 SatNav receiver, Loran C and

Decca navigators, and an adaptive autopilot are integrated into the system.

JO ASPEN

SEC

Circle 84 on Reader Service Card

The first of eight chemical/parcel tankers, the 12,600-dwt Jo Aspen, was delivered by Societa Eserizio

Cantieri (SEC) of Viareggio, Italy, to Jo Tankers of Norway.

Double-skinned and double-bot- tomed, the Jo Aspen has transverse cofferdams and is equipped with fully segregated ballast tanks. For worldwide chemical parcel service, the 456-foot Jo Aspen has a beam of 70 feet, depth of 34-1/4 feet, draft of 26-1/2 feet and cargo capacity of 14,000 cubic meters. She can handle up to 25 different grades of chemi- cals or a full cargo of high specific gravity chemicals, such as phospho- ric or sulphuric acid, at any one time.

According to the builders, she is one of the first of her size to have each of her 25 completely segregated cargo tanks built of stainless steel, making her suitable for food prod- ucts, chemicals and general petro- leum products. All her tanks can carry IMO II cargoes, while her two center tanks, separated from the others, are rated to carry IMO I cargoes.

Main propulsion is provided by two Wartsila 8R32D medium-speed engines, developing a total of 8,160 hp, coupled to a single Lips control- lable pitch propeller through a single reduction gear with two power take- offs for two shaft alternators rated at 1,650 kw each.

The Jo Aspen is equipped with a

Saab MaC501 remote controlled combined cargo handling/monitor- ing system, which enables the op- erator to control all pumps and main cargo valves. The system also houses a Saab TankRadar level indicator system, alarms and tank tempera- ture system.

Titovo Shipbuilding

Circle 92 on Reader Service Card

The third in a series of paper/ container/general cargo carriers, the

Lys-Skog, was delivered this past year to Lys Skog A/S of Oslo, Nor- way, by the Titovo Brodogradiliste

Shipyard, Kraljevica, Croatia.

The 295-foot Lys-Skog has a beam of 56 feet, draft of 19 feet and ton- nage of 3,900.

The machinery is fully computer controlled by an integrated ship con- trol system supplied by Norcontrol

Automation, and is visually moni- tored by a closed circuit TV system in the main engine room and four in the cargo hold. The Lys-Skog has the highest automation class and is operated by a crew of six.

Propulsion is provided by a single

Wartsila Diesel 6R32E diesel en- gine, which drives a Wartsila-

Wichmann four-blade stainless steel (continued on page 41)
