Abstract
With an increasing demand of a renewable energy, new offshore wind turbine farms are being planned in some parts of the world. Foundation installations need a significant cost of the total budget of offshore wind turbine (OWT) projects. Hence, a cost reduction from foundation parts is a key when a cost-efficient designing of OWT budget. Mono-piles have been largely used, accounting about 78% of existing OWT foundations, because they are considered as a most economical alternative with a relatively shallow-water, less than 30m, depths. And OWT design codes such as EC, GL, DNV, API, and Eurocode are being developed in a form of reliability based limit state design method. In this paper, reliability analysis using a response surface and simulation methods for an OWT mono-pile foundation were performed to investigate the sensitivities of mono-pile design parameters, and to find practical implications of reliability analysis.ce, a cost reduction from foundation parts is a key when a cost-efficient designing of OWT budget.
