Abstract:

Basic characteristics of an efficient transportation are safety, cost effectiveness and friendliness with the environment. According to various environmental impact assessments, ocean-going vessels, as the most important part of maritime transportation industry, will have increasing influence on the global ecosystem in the near future. In the modern approach to ship design the problems related to energy efficiency and environmental protection must not be left aside. A methodology for estimating the attainable speed in moderate and severe sea is proposed. Reliable ship speed loss estimation under real environmental conditions allows a more accurate prediction of the power increase and fuel consumption as well as gas emissions from ships.

The objective is to improve ship design and performance taking into accounts the environmental issue, creating a so-called eco-efficient or “green” ship design. The problem is multidisciplinary and requires the joint work of experts in the naval architecture, mechanical engineering, marine engineering and other engineering field.
