This paper provides a general insight into the importance of proper hull maintenance and suggests an optimal maintenance strategy for ship operators from both an economic and environmental point of view. Results of life cycle assessment show that significant cost reductions can be obtained by renewing steels every 10 years within the proposed hull maintenance strategy. The assessment also indicates that annual hull inspections and re-coating can contribute to reducing hull resistance and hence fuel consumption, thereby reducing the overall operating costs and emissions. This paper provides ship owners a direct relationship between effective hull maintenance and the reduction in maintenance cost. It also provides information to inform policy makers of the benefits of following a maintenance optimization strategy. This study shows that life cycle assessment can provide information to shipyards and owners to facilitate reliable long-term maintenance decisions.


Life cycle and cost assessment on engine selection for an offshore tug vessel
Oğuz, Elif; Wang, Haibin; Zhou, Peilin (2017-10-11)
The objectives of this paper are to find the most cost effective and environmental friendly engine configuration and its application on an offshore tug vessel in aspects of cost-benefit and environmental impact. This aim was achieved by a comparison of two different engine configurations applicable to the propulsion system for a case ship, which is currently at design stage in a Turkish shipyard. Options of engine selections are to choose either two large medium speed diesel engines or four small high speed...
Experimental and numerical analysis of a TLP floating offshore wind turbine
Oğuz, Elif; Day, Alexander H.; Incecik, Atilla; Amate Lopez, Juan; Sánchez, Gustavo; Gonzalez Almeria, Gonzalo (Elsevier BV, 2018-01-01)
This paper describes an experimental and numerical investigation of the Iberdrola TLP wind turbine concept, TLPWINID, in realistic wind and wave conditions. The TLP was coupled to the NREL 5 MW reference turbine and was designed to operate in a water depth of 70 m. The test campaign included free oscillation tests, tests in regular and irregular waves and simulated wind conditions.
Evaluating coastal scenery using fuzzy logic: Application at selected sites in Western Black Sea coastal region of Turkey
Ergin, Ayşen; Sahin, Fatma (Elsevier BV, 2010-05-01)
Coastal areas of the world are under treat due to the conflicting requirements of functions such as habitation and/or recreation, which affect the strategic asset of coastal scenery itself. Coastal managers, together with planners, need coastal landscape inventories, where the quality of coastal scenery is a part of the inventory. In order to provide an evidence-based approach for sound coastal management decisions, Ergin et al. (2004, 2006) developed a novel technique 'coastal scenic evaluation' (CSE), whi...
Benefit-cost analysis for retrofitting of selected residental buildings in İstanbul
Erdurmuş, Salih Buğra; Erant, Engin; Department of Civil Engineering (2005)
During the evaluation of the seismic retrofitting option for risk reduction/mitigation measures to be applied over buildings, Benefit Cost Analysis is an often-used method. During this study of Benefit Cost Analysis, the condition that the earthquake can happen just after or sometime after retrofitting will be taken into consideration rather than some approaches that focus on the benefits and costs regarding the annual probability of the occurrence for possible earthquakes. The analysis will use conditional...
Life cycle and economic assessment of a solar panel array applied to a short route ferry
Wang, Haibin; Oğuz, Elif; Jeong, Byongug; Zhou, Peilin (Elsevier BV, 2019-05-10)
This paper was to investigate the potential benefits of solar panel systems if applied for obtaining propulsion power of a short route ferry operating in the Marmara Sea. The life cycle assessment was applied to evaluate the long-term environmental impact of the solar power systems on-board in replace of conventional diesel engine systems. The cost and benefit of such systems were evaluated through the economic assessment where the life cycle cost relative to installation, operation and recycling of the sol...
