Fine mesh finite element analy- sis (FEA) was employed in the design of the long and large hull form, and ClassNK undertook its own independent analyses to con- firm this as part of the plan approval process. The ensuing design provides for a 14-row underdeck cellular stowage, with 16 rows accommodated on the weatherdeck and hatchcovers in tiers of up to six.

NYK Antares had the added dis- tinction of being fitted with the world's most powerful, single- engine diesel installation, in the shape of a Japanese-made 11- cylinder model of the Swiss-devel- oped, Sulzer RTA96C type.

Driving a single, FP propeller, the plant has a nominal rating of 82,170-bhp (60,390-kW) to ensure a laden service speed of 23 knots.

ClassNK technical staff oversaw testing of the two-stroke engine at manufacturer Diesel United's works in Aioi, and measured nitro- gen oxide (NOx) emissions during shop trials. They were found to be within the limits prescribed under new IMO Marpol requirements due to be implemented from

January 2000.

However, the propulsive energy incorporated in NYK's liner fleet flagship is set to be surpassed by the machinery subsequently com- pleted and tested at Aioi for supply to the first of the 6,674-TEU new- buildings ordered by P&O

Nedlloyd.

Weighing 2,030-tons, the mas- sive, 12-cylinder Sulzer RTA96C engine will give a record-breaking 89,640-bhp (65,880-kW), to power the ship at speeds up to 25-knots.

The recipient vessel, the first of four from IHI's Kure yard in west- ern Honshu, is due to be phased into the trade between eastern

Asia and Europe during the spring of 1998.

The program of RTA96C produc- tion at Diesel United, jointly owned by IHI and Sumitomo

Heavy Industries, is indicative of the long and close ties between the

Japanese licensee and the Swiss engine designer, now part of the

Wartsila NSD Corporation.

A distinguished record of culti- vating business with leading for- eign names has also been demon- strated by IHI with the delivery of the 4,062-TEU, Champion-class containership Sea-Land

Lightning.

The new vessel marked the com- pletion of the latest four-ship con- while two more boxships of the type are scheduled from MHI, along with one from MES during the first-half of 1998. Built to a 131-ft. (40-m) molded breadth and to Nippon Kaiji Kyokai (ClassNK) rules, the new design has been capacity-optimized within dimen- sions governed by draft restric- tions and the outreach of post-

Panamax dockside gantries already in place at ports on NYK's

Asia/Europe express route.

As an element of the exercise in optimizing revenue-generating vol- ume, NYK Antares has been con- structed to a girderless design.

This has allowed an additional row of containers to be carried below decks, compared with the usual box girder arrangement, which provides longitudinal rigidity and support for the container load.

The requisite reinforcement has instead been achieved through closer attention to the design of the hatchcovers, upper deck, cross deck members and longitudinal and transverse bulkheads, and scrutiny of the hatchway corners to
