Abstract | PhD | Øystein Mejlænder-Larsen

The oil and gas industry is characterized by large and complex projects and has invested heavily in the development of new technology. Project execution models (PEM) have been introduced as a structured way of executing multidisciplinary work processes through all project phases. Building information modeling (BIM) is utilized in the coordination of complex projects and is part of the work processes defined in a PEM. This has been the basis for the first research question: How are PEM and BIM utilized in major oil and gas projects in the cases studied? The trend towards larger and more complex projects in the construction industry means that actors in the construction industry would benefit from acquiring knowledge and learning from the oil and gas industry. This has been the basis for the second research question: How can experiences from the cases studied be relevant for improvements in construction projects?

A case study research method is used. Data is collected through interviews, document studies and observations. The data is analyzed using the stepwise-deductive-inductive (SDI) method. The cases are offshore projects in the oil and gas industry through three ongoing projects ‒ the topsides of the Eldfisk, Edvard Grieg and Johan Sverdrup offshore platforms.

The first research question has generated three main themes, while the second research question has generated a basis theme. Research in the basis theme indicates that it is possible to generalize findings related to PEM and BIM through case studies, and that it is highly relevant to adapt the findings from the case projects to projects in the construction industry. In main theme 1, a flowchart with describes the principles in a change control system, for managing and controlling design change requests, supported by a change management process, is developed. In main theme 2, a three-step process for reporting progress in detail engineering with the use of BIM is developed. In the first, necessary preparations are made in building information models. In the second, both visual and overall progress can be reported using BIM. In the third, the overall progress is connected towards an engineering schedule. In main theme 3, a combination of three aspects increases collaboration between engineering and construction in detail engineering. The first is related to how the parts of the building information models that are frozen determines the degree of parallelism between engineering and construction and how engineering can adapt a construction sequence using a PEM. The second is related to the transition towards relational contracts and selecting and developing the engineering team. The third is related to constructability and how an engineering contractor can split building information models in accordance with the requirements of the main contractor towards fabrication.
