Versatile, efficient products tanker Kihu, built by Wartsila's Turku Shipyards, is powered by

Wartsila/Pielstick diesel engine with maximum continuous rating of 9,776 bhp.

Crude/Chemical/Products Tanker

Delivered By Wartsila's Turku Yard

The Turku Shipyards of Oy

Wartsila ab in Finland recently de- livered the 19,999-dwt products tanker Kihu to Neste Oy, the na- tional oil company of Finland. Less than a year elapsed between her keel laying and delivery. The ship is classed by Lloyd's Register of Ship- ping + 100 Al, Chemical Tanker, + LMC, IGS, Ice Class 1A. She is an

IMO type II/III chemical tanker for worldwide trading of crude oil, re- fined petroleum products, and type

II/III chemicals including benzene, styrene monomer, caustic soda, mo- lasses, urea, solvents, and alcohols.

The vessel has an overall length of about 528 feet, molded beam of 75.8 feet, molded depth to upper deck of 46.6 feet, and draft of 33.2 feet.

Total cargo tank capacity (100% full) is 26,644 cubic meters.

Main engines, auxiliary engines, boilers, and inert gas generator are all designed to run from start to stop on one grade of fuel oil—3,500 sec- onds Redwood at 100 F.

The Wartsila/Pielstick 6PC4.21- 570 main engine is coupled through a reduction gear to a KaMeWa con- trollable-pitch propeller. The en- gine has a maximum continuous rat- ing of 9,776 bhp at 400 rpm; service speed operating at 82 percent of mcr is 15.5 knots. The ship is fitted with a controllable-pitch bow thruster powered by a 1,340-hp electric mo- tor.

Three Wartsila-Vasa 6R22HF auxiliary diesels are direct-coupled to Stromberg alternators of 935 kva, 450 volts, 60 Hz each. Two oil-fired steam boilers and one exhaust gas steam boiler are installed for ship's service, which include heating of cargo and ballast tanks and cargo tank washing water.

The hull is divided, by two longi- tudinal and 11 transverse bulk- heads, into 10 center tanks and eight wing tanks for cargo, six wing tanks for water ballast, and two slops tanks. Transverse bulkheads are stiffened by corrugations; longi- tudinal bulkheads in the center car- go tanks are smooth, with stiffeners in the wing tanks. The center tanks are coated with pure epoxy; cargo side tanks are coated with zinc sili- cate.

Despite being a ship of less than 150 meters BP (492 feet) and less than 20,000 dwt, the Kihu incorpo- rates some of the more stringent requirements applicable to larger vessels. Her damage stability meets most requirements valid for ships above 150 meters; she is fitted with crude oil washing and inert gas sys- tems; and she has segregated ballast water tanks with capacity sufficient for the ship to operate in heavy ice conditions. Hull and propulsion ma- chinery are designed for these con- ditions, above the requirements of

Lloyd's Register Ice Class notation.

The four segregated cargo system are designed for efficient operation; discharging time is about 12 hours, and loading and deballasting time is about five hours. A cargo computer is connected on-line with level transmitters of cargo, ballast, and bunker tanks, cargo tank tempera- ture system, draft sensors fore and aft, and an inclinometer.

Each cargo tank is equipped with one vertical, centrifugal, hydrauli- cally driven pump of Thune Eureka manufacture. For cargo heating, 18

Sunrod heaters are installed on the main deck. One Maritime Protec- tion inert gas generator is installed in a deckhouse aft. Its capacity is 3,300 cubic meters per hour with a maximum pressure of 0.2 bar.

Big Ship Radar Line

Introduced By Furuno

Furuno is now offering a full line of 12 and 16-inch radars designed to meet all current IMO requirements for ocean-going vessels. These new radars offer the most modern tech- nology, with features such as digital signal processing for an extremely bright steady picture, an interscan system for continously visible elec- tronic bearing line, "echo stretch" technique for positive target defini- tion, video processing for clutter suppression, hybrid microwave IC receiver circuitry for high sensitivi- ty, and log amplifier for enhanced target detection at all ranges, even during heavy weather.

Furuno can provide a variety of system configurations: the trans- ceiver may be mounted aloft in the scanner gearbox or below in a sepa- rate enclosure; both 25-kw X-band and 60-kw S-band frequencies are available and can be interswitched;

X-band antennas can be specified from 6.5 to 10 feet, while the S-band units feature a 12-foot antenna. All models offer dual VRM's and 10 range scales to 120 n.mi., plus a 12- mile True Motion scale. The presen- tation can be head-up, north-up or course-up and the picture can be offcentered by as much as 70 per- cent in any direction. The 12-inch units are used as primary radars for vessels under 10,000 grt or second- ary radars for vessels over this size.

The 16-inch units have been devel- oped as primary radars for vessels of any size.

Convenient options include an- tenna de-icer, radar alarm, reflec- tion plotter, North-up and True

Bearing modules, performance monitor, inter-switch, and ARPA interface.

CSSRA Annual Conference

Scheduled For February 19 1985 In Montreal

Plans are moving ahead for the 37th Annual Technical Conference of the Canadian Shipbuilding and

Ship Repairing Association to be held at the Queen Elizabeth Hotel in Montreal, Quebec, on February 19, 1985. The program will be pre- sented in two separate halls—one primarily for the shipbuilders, the other of more general interest to both shipbuilders and allied indus- tries.

This annual conference, always held in Montreal, is by far the larg- est and best-known CSSRA event, and is well attended by members of the marine community.

For additional information on the conference, contact CSSRA secre- tary/treasurer Mrs. Joy Mac-
