Abstract Incorporating reliability in the early stage of a design process is important to reduce the chance of overlooking functional requirements that, if not included, will require redesign at a later stage. Reducing such risk in early design phase relies on the ability of reliability analysts and designers to cooperate very closely. Key actors in subsea oil and gas industry have pointed out that available frameworks are not so detailed on how this can be achieved for novel and specialized products. The purpose of this paper is therefore to propose a framework for the handling of reliability in subsea design, and to suggest how to develop the reliability specification in close collaboration with the system design team. A novel subsea design concept is adopted as a case study to demonstrate the application of the proposed framework.
