As oil and gas (O&G) activities are moving north in the Arctic region, new challenges for the offshore logistics have arisen. These challenges will impose more stringent requirements for the logistics system, especially on the design and operation of vessels, which will drive the cost and environmental impact of offshore logistics. Copying the logistics system and vessels designed for the North Sea is not a sustainable way forward. Without making major changes to the logistics when moving into remote Arctic areas, Statoil believes that the logistics cost will easily increase from 20% to 35% of the total well costs. Logistics is thus considered a major obstacle for further field development in the Arctic. Hence, the project vision is to contribute to the realization of the development and value creation of O&G activities in the Arctic region, through finding new solutions for offshore logistics which ensures a safe, environmentally friendly and profitable operation. In the development of new solutions, there are some important questions that need to be investigated: - Onshore or offshore supply base? - Conventional rigs or area-specific and highly self-supported drilling vessels? - Single, dual or multi-purpose service vessels? - Optimize ship design for efficient transport or for dynamic positioning (DP) capability? - How should the vessels be scheduled in terms of routes and speeds? - What is the impact of safe transport of personnel? This project aims to answer such questions by building knowledge, methodologies and analytical tools that enable robust feasibility studies and verification of expected performance of alternative logistic solutions. Such achievements can only be done in joint effort between experts within O&G field development, offshore shipping and offshore vessel design. All together with world-leading researchers within maritime logistics system and ship design. In 2015, the project focused on gathering data about existing logistics systems, operations and vessel designs. This was summarized in an AS-IS report. Further, the feasibility study phase was started, building cost-benefits models for assessment of logistic system alternatives. 3 two-days workshops with attendance from all consortium partners were arranged in 2015. Late May 2016, the 4th workshop in project was arranged. The delivarbles for this workshop included a methodology and model for feasibility studies, together with two case studies performed with these tools. Additionally, two sketches of new ship concepts were presented together with an assessment of winterization requirements and consequences of the Polar code. The activity in the autumn of 2016 focused on two case studies, one from Newfoundland and one from the Barents Sea. This continued early 2017, where also an activity on designing ship concepts with personell-carrying capacity was started. The last phase of the project has focused on developing a simulation model for virtual testing and evaluation of new logistic and vessel concepts for offshore supply. This model has gone through successful pilot testing by the industry partners of the project.
