SHIPBUILDING 316 Wartsila Delivers Combination Tanker xTavi' To Neste Oy The Turku shipyard of Oy Wart- sila Ab recently completed the 19,999-dwt crude oil/chemical/ products tanker Tavi (shown above), first of two ordered by Neste Oy, the Finnish national oil compa- ny. The vessel was delivered less than 14 months after keel-laying. The Tavi is built to Lloyd's Regis- ter of Shipping classification +100 Al, Chemical Tanker, +LMC, UMS, IGS, Ice Class 1A. She is an IMO type II/III chemical tanker for worldwide trading of crude oil, oil products, and type II/III chemicals including benzene, styrene non- omer, caustic soda, caustic potaska, molasses, urea, white spirits, sol- vents, and alcohol. The cargo list comprises 72 different chemicals most widely transported by sea. The tanker has an overall length of about 528 feet, beam of 76 feet, depth to upper deck of 46 Vi feet, and design draft of 33 feet. Propul- sion is provided by a Wartsila/Piel- stick 6PC4.2L-570 diesel engine Each cargo tank is fitted with a Thune Eureka deepwell pump. For cargo heating, 18 Sunrod heaters are installed on the main deck. One Maritime Protection inert gas gen- erator is installed in a deckhouse aft. The generator has a capacity of 3,300 cubic meters per hour with a maximum pressure of 0.2 bar. Despite being a ship less than 150 meters (492 feet) and of less than 20,000 dwt, the design of the Tavi incorporates some of the more se- vere requirements applicable to larger vessels. These include dam- age stability, segregated ballast water tanks, crude oil washing, and the inert gas system. coupled through a reduction gear to a KaMeWa controllable-pitch pro- peller. The engine has a maximum continuous output of 9,776 bhp at 400 rpm. The ship is also fitted with controllable-pitch bow thruster driven by a 1,000-kw electric motor. Three Wartsila-Vasa 6R22HF aux- iliary diesels are direct-coupled u> Stromberg 935-kva alternators. Main and auxiliary engines, boilers, and inert gas generator are all able to run with one kind of fuel on board—3,500 sec Redwood at 100 F. The hull is divided, by two longi- tudinal and 11 transverse bulk- heads, into 10 center tanks and eight side tanks for cargo, six side tanks for water ballast, and two slop tanks. Transverse bulkheads are stiffened by corrugating; longitudi- nal bulkheads are smooth in the center tanks with stiffeners in the side tanks. Center tanks are coated with pure epoxy; cargo side tanks are coated with zinc silicate. SweetWater RO Unit Selected For Antarctic Expedition By British Peter A. Malcolm, Marine Co- ordinator of "In the Footsteps of Scott," a British expedition to the Antarctic, has selected the Sweet- Water 400 RO (reverse osmosis) unit as the onboard water supply for this historic, two year voyage. Bob Daniels, president of Mar- land Environmental Systems, mak- ers of SweetWater Systems stated: "I'm excited and proud that the British have chosen a SweetWater RO Water Purification unit. Sweet- Water systems are dependable workhorses, capable of delivering a continuous supply of pure, clean potable water, from any ocean in the world, even under adverse condi- tions, such as found in the Antarc- tic." SweetWater units are complete purification and water production systems. The main frame and the precise pre- and post-filtration com- ponents necessary for the RO mem- branes to function at maximum lev- el are included. The SweetWater 400 unit will be installed in a converted Islandic trawler recently used for oil pollu- tion control. It will be reconditioned to meet Lloyd's standards of an Ice Class III vessel for this expedition.
