Subsea Tiebacks are one of the offshore field development methods. The explored hydrocarbon is transported via pipelines and connected to the 3rd party infrastructures, either subsea, platform structure, or onshore.
The world's 10 longest subsea tieback projects are introduced in OE magazine in December 2017 issue, as follows:
DNV GL has updated its standard "Submarine Pipeline Systems" DNV-OS-F101 and renamed as DNVGL-ST-F101.
Its revision takes into account the findings from joint industry projects such as pipe-in-pipe (PiP) systems and reflects the conclusions on selection of safety classes, limit-state criteria, etc.
Various requirements related to linepipe fabrication, welding and non-destructive testing have also been updated due to advances in technologies and laboratory tests on materials, corrosion, flow, and failure, etc.
The requirement to fill the empty pipeline with water is now removed in the new revision, which can reduce the cost for pipeline operators, although additional work will be necessary to prove an equivalent safety level.
Jay delivered one day lecture at KITECH (Korea Institute of Industrial Technology) on Offshore Pipeline Systems as part of the government funded offshore plant training program for engineers.
The KPC 2017 was a big success for the first attempt in the oil crisis. It was a memorable event to see many industry and academia experts in pipeline sectors both onshore and offshore, from around the world. Thanks to the organizers, KOSA and KIMEX, and committee members including session chairmen for their dedication. Hope to see this event every year to come. Jay was very proud with serving the conference as a chairman of the committee members.
Remitite is a world-renowned fire-resistant rubber products manufacturing company in Korea. Jay Lee met with the company's president a few years years ago before Remitite established their branch office in Houston, in early 2017. Since then, Jay is helping Remitite as a technical adviser. His job is to link/introduce Remitite to North America market, especially Houston based offshore/onshore energy companies/contractors.
