Austal is able to evaluate the natural frequency of plate panels and plate stiff- ener combinations, taking into account the panels' edge constraints and other variable such as water on one side of the plate panel. Various panels are then turned to ensure their harmonics are out of phase with the natural operating fre- quencies generated. In addition to this vibrational design approach, the global waterjet structure is designed to satis- factorily transmit the waterjet thrust and steering loads into the surrounding structure. The design group then creates detailed finite element analysis structur- al models and the results are assessed to ensure that the fatigue life of the struc- ture is optimized. Particular attention is paid to structural detail in order to avoid discontinuities and other stress raising features.

Increased Power

For The Sulzer RTA96C

Wartsila Corporation has increased the power outputs available from Sulzer

RTA96C low-speed marine diesel engines by approximately four percent, and also added a 14-cylinder model to bring the maximum output available up to 80,080 kW (108,920 bhp).

The higher powers and the 14-cylinder engine are intended to meet the require- ments of shipowners and shipbuilders for both large, fast post-Panamax con- tainerships and the next generation of larger ships of up to 10,000 TEU. The

RTA96C now gives 5,720 kW (7,780 bhp) per cylinder maximum continuous output at 102 rpm. Thus the power out- put of the 12-cylinder RTA96C is increased from 65,880 kW (89,640 bhp) maximum continuous output to 68,640 kW (93,360 bhp).

The RTA96C is the most powerful in the Sulzer RTA series of low-speed marine diesel engines. The new

RTA96C engines have the same dimen- sions and masses as the existing

RTA96C engines built to the latest design standard.

They also have exactly the same brake specific fuel consumption (BSFC) and cylinder lubricating oil feed rate. Their times between overhauls are expected to be three years for major components.

The NOx emissions of the RTA96C are within the limits set by the IMO regula- tion in Annex VI of the MARPOL 73/78

Convention.

Four Sulzer 12RTA96C low-speed diesel engines have been ordered by

Odense Steel Shipyard A/S in Lind0,

Denmark, for installation in four large post-Panamax container ships building there for A.P. M0ller. The four ships are of A.P. M0ller's S-/C-class, each having 1-800-231-3628 281-448-5800
