Subsea 7 Presents Two Technical Papers at Offshore Europe 2009

09 September 2009

Subsea 7 Inc, one of the world's leading subsea engineering and construction companies, will present two technical papers on Thursday 10th September at the Offshore Europe Conference in Aberdeen, Scotland.

The first paper, "The development of Subsea Grouted Tee for Subsea Live Pipeline Intervention”, will be presented as part of the Facilities and Infrastructure session in the Gordon B room at 11.30hrs by Paul Booth (Engineering Manager) and Dan Vu (Project Engineering Manager) of Subsea 7.

Grouted Tee™, which is DNV approved for subsea use, is now a proven and accepted method of carrying out live intervention on large diameter transmission pipelines, without the need for hot tap welding. The branch sizes can be equal to the diameter of the main pipes and therefore suitable for total flow isolations applications. Compared to alternative methods, it is therefore a safer option with reduced risk and offers zero disruption to production throughout the installation process.

The paper details the Subsea Grouted Tee™ (SSGT) conversion programme and design parameters, together with client and industry benefits. It reveals key design features for diver depth capabilities which are adaptable to ROV deployment, making diverless live intervention in deepwater pipelines a closer reality. It will also give details of the successful offshore trial which took place in June 2009.

The second paper, "Jura Fast Track Project”, will also be presented as part of the Facilities and Infrastructure session in the Gordon B room, at 12.00hrs by Phil Simons (Operations Manager), Subsea 7 and Jerome Lesgent and Jimmy MacIntosh of Total.

This paper focuses on Total E&P UK's strategy for the fast track development of the Jura Project in the North Sea and the resultant challenges. Subsea 7 was the lead subsea contractor on the project which has advanced pipeline bundle technology through new fabrication, transportation and integration techniques.
