Transport of China, claimed to be the first newbuilds of this type or- dered by Asian owners from a Euro- pean yard. The vessels have sleep- ing accommodations for 938 passen- gers, as well as a capacity for 215 cars and 80 trucks. Two 5,760-kW Stork Wartsila W38 engines will provide the power, turning a pair of Lips CP propellers. A 900-kW bowthruster is also fitted. Isle of Innisfree, which entered service with Irish Ferries in May this year, illustrates the time-sav- ing advantages of the standard de- sign principle. The 596-ft. (181.6- m) vessel was delivered within 14 months of design work completion. The customer—in an effort to maxi- mize profits during the peak sum- mer season — decided to stretch the ferry by inserting an extra 49-ft. (14.85-m) mid-section. This deci- sion was made at the tank testing stage. The result is a highly effec- tive ship with day accommodations for 1,650 passengers and more than 100 articulated freight vehicles. Four Sulzer ZA40S engines — de- veloping a total of 23,000 kW — drive a pair of KaMeWa highly skewed propellers via Lohmann and Stolterfoht gearboxes. A pair of 1,500-kW KaMeWa bowthrusters are fitted, and powered by ABB shaft alternators. In contrast, the 10th RoRo is not like any of the previous nine. Real- izing the limitations of its 76.7-ft. (23.4-m) beam, and seven-vehicle lane, the company began the devel- opment of a new eight-lane stan- dard design in 1993. Although this work was nearing completion, the team had to make a complete reap- praisal when the Estonia sank. Modifications were made, and in April, Stena Line ordered a 595-ft. (181.5-m) x 91-ft. (27.8-m) RoRo/ train/passenger ferry with a pro- jected delivery date of May 1996. The vessel will have a train track length of 1,870 ft. (570 m), a trailer lane length of6,900 ft. (2,100 m) and will be able to accommodate 1,500 passengers and 550 private cars. Damaged stability on the new design has been tackled by a variety of measures. The design includes two 11.5-ft. (3.5-m) high longitudi- nal bulkheads which stretch three- quarters of the ship's length. Top- hinged watertight doors at each end form two enclosed freight vehicle lanes on each side of the ship. A second inner bow door will be incor- porated, and a new bow door/ramp arrangement — devised by Kvaerner Ships Equipment — will be fitted. This is a system which meets all the new Scandinavian re- quirements, including: the ability to withstand higher sea loads; im- proved locking devices; and separa- tion of the inner and outer parts of the ramp when stowed. Subsequently, the yard's finan- cial situation has improved. In 1993 it was able to sever all fiscal ties to the Dutch government, and addi- tional investment has been made or is planned. The CAD/CAM system originally installed in 1990 was re- October, 1995 cently upgraded to the TRIBON system from Kockums Computer Systems. A new plasma cutting machine began work at the begin- ning of the year, and a shot-blasting and painting hall is currently under construction. The next project is to extend the existing outfitting quay by around 200 ft. (60 m). ouatech Stainless Boat Shafting 21 st.Century Shafting Technology Since all stainless steel boat shafting made of certain alloys must meet or exceed federal and ABYC requirements, what's the difference between brands?
