JSMDA DEVELOPS NEW ENERGY-SAVING DEVICES. "T" STERN FORM AND NO-ENGINE ROOM SYSTEM

The new stern shape, designed to match a larger-diameter propeller, features a tunnel extending from the midship bottom section to the stern bottom. This improves the flow of water around the stern, and at the same time increases the deadweight capacity as much as the engine and fuel tank space can be reduced. Comparison with conventional hull form is given for a 74000 dwt bulk carrier. With the "no-engine room system", the effect is to be doubled by the combined use of electrical propulsion system based on multi-level engine room arrangement.
