This research investigates the subject of current shipbuilding practices and two offshore structures projects, focusing on information transfer between project process phases. Large construction projects, as offshore structures, are often subjected to substantial economic and environmental risks. A holistic approach to the project execution could help mitigate some of the problems that yards, engineering firms and marine contractors face today. Research has been conducted into the area of EPC offshore structures projects and the need for predictability, shortened lead times and increased flexibility. The literature study performed as background to this research, shows that there are few studies covering information management between offshore structures project phases. A case study was performed to further explore and enrich the empirical findings. Concluding that information is insufficient between project phases, looking ahead, the question is raised: In what way can information be improved between project phases?
