Two energy saving indices have been used to evaluate the energy saving performance of a number of large <200,000 dwt class> tankers and bulk carriers built by IHI, Japan. The results of the case study suggest four main considerations for the planning of energy saving ships, viz. 1. Reduction of Service Speed; 2. Improvement in Hydrodynamic Performance; 3. Improvement of Propulsion Plant Efficiency; 4. Increase in Deadweight Capacity. The specific measures to implement each of these factors are described in detail. They include the IHI LV hull form, A.T. <additional thrusting> fin for recovery of energy loss due to rotational flow and SSG <Super Economical Shaft Generating System> Mark II for recovery of waste heat energy.
