Abstract
Abstract Risers play an important role in the drilling, production, and transportation of hydrocarbons and other fluids associated with offshore oil and gas production. For a floating production system, risers provide the link between the surface facility and the subsea flowlines / pipelines that in turn link to the oil/gas wells, and to the on shore storage and export facility. Risers are one of the most challenging aspects of deepwater projects, and also have a direct influence on the selection and design of both the floating facility and its mooring system. There are a number of deepwater riser concepts. The most economical solution is typically Steel Catenary Risers (SCR) which are made up of welded rigid pipe sections. The main advantages of SCRs is that the steel pipe has a relatively low cost and there are relatively few other components to consider. However, the construction and long term fatigue performance of the SCRs present significant challenges to the engineer. The environmental conditions in the deepwater areas of East Kalimantan, Kutei basin can prove suitable for the application of SCR riser concepts. The first application of SCRs in the Kutei basin is on the West Seno Floating Production Unit (FPU). This is also the world's first application of SCRs supported by a barge type floating structure. This paper presents an overview of the application of SCRs in the Kutei basin with reference to West Seno field experience. The following areas are addressed: Design and engineering;Material selection;Welding issues, qualification of welding procedures and fatigue tests;Construction, inspection, NDE, acceptance criteria;Pre-installation, hook up and as installed configuration verification
