Oject-oriented methodology for subsea project execution
MetadataShow full item record
Object-orientation refers to the holistic description of a component (object) as a single entity in a single database. By modeling real world entities in their true to life representation and using the object model as a data platform, one can create a common understanding and communicate about complex systems more efficiently. Through literary research and interviews with key personnel in Aker Solutions ASA, this study revealed that the company’s subsea organization has a document-oriented approach to project execution, where engineering deliverables are planned and measured primarily based on the status for documents included in the master document list (MDL). Information contained in the MDL documents collectively captures the life cycle information (LCI) required by operators to install, operate and service the supplied hardware. Dividing the information in documents allows for a manageable way to create progress plans, split the workload, execute document reviews, revision control and monitor the engineering progress. However, the document-oriented approach also has several challenges. One being that the document contained information cannot be automatically extracted and exchanged, which results in a static information library. In addition to the challenges related to the document-oriented approach, Subsea also has challenges associated with its IT system architecture. Primarily that they do not have a unified software platform for system and application engineering. Instead they are relying on multiple stand-alone software solutions, which inhibits data consistency, information exchange and reuse of engineering. The goal is to solve these challenges by implementing object-orientation in the subsea project execution model. It exists several software solutions based on object-orientation, but COMOS is the preferred software platform for Aker Solutions. This is partially due to historical decisions which have resulted in the company’s existing IT architecture. Naturally there are challenges with implementing object-orientation that need to be addressed, but this thesis concludes that object-orientation methodology has the potential to significantly improve productivity and quality for subsea project execution, if implemented correctly and used in its full capacity. Keywords: Operational excellence, object-orientation, digitalization, project control, collaborative engineering, knowledge management, standardization and reuse.
