... Abstract Presently, drilling riser joints are inspected every five years. This is usually accomplished by rotating 20% onshore every year to be dis-assembled and inspected. This requires extensive boat trips from a mobile operating drilling unit (MODU) to onshore and trucking of the riser...

... Abstract In the current low oil price market, innovative low cost solutions are necessary for development of new fields and life extension of existing fields. For deep water applications, Steel Catenary Risers (SCRs) and Steel Lazy Wave Risers (SLWRs) provide low cost alternatives to flexible...

... The Anasuria FPSO was installed in 1995 to allow production from the Teal, Teal South and Guillemot developments. The risers and bend restrictors were pulled in through the chain table. Divers that were based on the FPSO secured the bend restrictors to the chain table with a combination of nuts...

... Abstract The paper addresses the use of steel chains in a lazy wave configured flexible riser system to provide an alternative flexible riser configuration for use in challenging environments including large vessel offsets and motions, and large ranges of riser internal fluid properties. While...

... The arrangement of the turret system will enable anchor line and riser installation without the need for diving. The turret structure will be designed for a minimum 25-years life. Similarly, swivel seals may require change-out in the course of the operations. Seal change-out will be possible...

... Abstract The design and operation of an FPSO in remote locations requires detailed information on the structural response of the vessel within the local environment offshore. Monitoring of critical components including the risers, hull and mooring lines simultaneously with the local...

... The riser is tensioned at surface via a riser tension system (as shown in Figure 1 ) located on the CTU Deck. The system consists of a tension table with 4 hydraulic cylinders and an air operated HPU control unit. The tension is applied to the riser via a ‘C’ plate and slim-line tension ring...

... to provide close up inspection, do not provide real-time information in the event of a mooring line failure or problem with the risers. Through the application of multibeam sonar technology, operators can now have real-time 24/7 information on the presence and position of mooring chains, risers...
