Abstract
This paper presents a case study of a semisubmersible drilling unit regarding the fatigue analysis. Drilling operation in deep water, harsh environment and remote locations becomes a key trend for the offshore industry to fulfil increasing demand for energy. For operational conditions wave induced loads are more significant for the offshore installations. Therefore, to ensure integrity and structural safety, the wave induced loads have to be taken into account. One of the approaches to accomplish this task is to perform a fatigue analysis with the extreme environmental loading on the offshore platform using rules and practices recommended by classification societies.
