FPSO Topside Standardisation

The objective of the paper is to explain the need of standardisation in design and construction of Topsides for FPSO. The main target is to reduce design error, improve engineering process, support procurement and ensure repeatability. The scope of this paper focuses on the complex design process that is required to be performed at conceptual and FEED stage, then further carried over to Detailed Engineering, Procurement, Construction, Commissioning and Operation stages. This s focuses on specification and standardisations involved across all disciplines including mechanical, piping, structure, instrumentation and electrical. The utilisation of the standard will be taking place at all levels, namely Module, System and Equipment. The approach concentrates on the deployment of these engineering standards and specifications early on so that they can be used throughout the project. The information is to be made available in the form of guidelines. The second part of standardisation is at component or product level. In order to streamline the diversity of the options, the standardisation is the substance to reduce variety by specifying the component that will be associated with the equipment, system and module. There is tremendous reduction of work when commonality is implemented across the topside. ‘Construction hat’ thinking was one of the features in standardisation. We encourage two-way discussion and feedback with fabrication and construction. Apart from ensuring the constructability, the ability to source the material is one of the important benefits. Similarly, for Operation, close relationship with the operator will ensure the operability and maintainability of the asset that has been constructed. Through the implementation of these engineering standards and specifications, one avoids performing unnecessary basic engineering works. For example, piping specifications that we generate are based on pipe specification from standards (e.g. API, B31.3). Specific project requirements may result in changes to these standard industry specifications.
