Investment in Dcsiizn for power requirements up to a stunning 108,920-bhp (80,080-kW). The 19,280- bhp (14,200-kW) step-up in maximum unit output secured by the uprating in combination with the inclusion of a 14- cylinder model offers a 25-knot, single- engine, single-screw answer for vessels of up to 10,000-TEU. It also enables faster speeds to be engendered in exist- ing sizes of post-Panamax container car- rier, assuming that the space and weight penalties can be offset by the speed gains. After all, increased power of the mag- nitude offered will necessarily mean higher engine weight and increased engine room length. Furthermore, there may be something of a psychological barrier to be crossed by shipping compa- ny engineers in adopting a 14-cylinder format of crosshead engine. But radical engineering steps are needed to secure the advances in linehaul vessel capacity demanded by shipping economics. The industry's clear preference for sin- gle, diesel prime mover installations gives a pragmatic commercial basis to the Wartsila move, complementing the technical case. In fact, rival MAN B&W has conceptualized 13- to 18-cylinder in-line versions of its large-bore K98 engines, which could potentially cover the needs of a future generation of 25- knot vessels with stow capacities up to 18,000-TEU. Experts believe that ship sizes between VT Chosen By The Royal Navy Vosper Thornycroft has won the com- petition to build a trio of Offshore Patrol Vessels in Southampton for the Royal Navy together with related logistic support. The contract calls for the lease of three ships over an initial five-year period together with a full support package. The vessels will be used by the Royal Navy to replace existing ships involved with Fishery Protection Duties. The design has been especially prepared for the Royal Navy's requirement but will have export prospects in the growing Economic Exclusion Zone market.

(15.3 m). As it stands, nowhere in Europe has the production capability for the 14- cylinder Sulzer engine proposed by Wartsila. The Finnish power system supplier's largest factory, the former Grandi Motori Trieste plant in Italy, can build diesels up to the 8RTA84C size, of some 44,000-bhp. The RTA96C accord- ingly falls exclusively within the province of Far Eastern licensees. Hyundai, the world's most prolific marine diesel engine manufacturer, has recently taken a global lead by readying its global works to fabricate and test two-stroke engines in excess of 100,000-bhp.
