Design and Installation of Auger Steel Catenary Risers
2020Co-Authors: E.h. Phifer, Frans Kopp, R C Swanson, Don W Allen, C.g. LangnerAbstract:The Auger export pipelines are connected to the TLP by steel catenary Risers (SCRs). This is believed to be the first time steel pipe has been used for catenary Risers. SCRs offer advantages over tensioned Risers, since SCRs need no heave compensation and no subsea connections, and over Risers made of flexible pipe, since SCRs are much less expensive. However, significant design effort was required to prove that the SCRs could safely withstand environmental loads and the effects of TLP motions. The design effort consisted of extensive dynamic analyses as well as full scale fatigue testing of both the Riser Joint welds and the flexible Joint that connects the Riser to the TLP pontoon. Devices which suppress vortex induced vibrations were also tested. SCR installation is accomplished by lowering the Riser on the abandonment and recovery cable from the J-Lay installation vessel and transferring the Riser on a chain that is run through a chain jack hung from the TLP upper deck structure. A special Installation and Maintenance System was built for this purpose.

First offshore composite Riser Joint proven on Heidrun
2020Co-Authors: Bjørn Melve, Petter Fjellheim, Stig Raudeberg, Siv Arna TanemAbstract:Demand for strong yet lightweight materials able to stand up to the harsh subsea environment has spiked, with a corresponding peak of interest in composites. Composite Risers have been an aim because they can offer real performance benefits vs. traditional steel, especially as offshore production moves to deeper water.

Composite Drilling Riser on Heidrun: A Decade in Operational Experience
Volume 6: Materials Technology; Polar and Arctic Sciences and Technology; Petroleum Technology Symposium, 2012Co-Authors: Bjørn Melve, Kristin Nedrelid, Siv Arna Tanem, Lasse Kroknes, Stein H. MyrmelAbstract:A drilling Riser Joint with carbon fibre in the main structural body and titanium end flanges was put into service at the Heidrun TLP in 2001. The Joint has an internal titanium liner. The Joint was the first implementation of an offshore composite Riser and was the end result of the CompRiser project.The composite Riser Joint has an internal diameter of 560 mm (22”) and is 15 m (48 ft) long. The Joint is a part of the marine Riser. The Joint has been in service for ten years and has been treated as its metallic counterparts.At the periodic inspection done in 2010, it was decided that the external layer needed refurbishment.Inspection and pressure testing showed that the properties of the Joint had not changed during service.Copyright © 2012 by ASME
