Ennsub completes Wheatstone LNG work

LNG Industry,

Ennsub has completed the design, manufacture, testing and installation of bespoke sealing systems for the Wheatstone LNG platform off the coast of Australia.

Ennsub was approached to design an external and internal sealing system for 64-off 8 in. NS ballasting pipes located at each corner of the LNG platform.

The company was responsible for the design and supply of all equipment, including downline recovery winches, remote disconnect heads and isolation plugs. Four Ennsub engineers were mobilised to Australia to perform the installation of the 128-off bespoke sealing systems, following an intensive factory-acceptance test programme, which simulated the offshore conditions.

The Ennsub solution replaced the alternative grouting solution, which was being considered by the end user. Ennsub successfully completed the installation in half the time allocated.

Scott Macknocher, Managing Director of Ennsub, said: “This was a great opportunity to demonstrate our design, innovation and supply capability on such a prestigious project. Our experienced design team gained a real understanding of the industry and project application.

“We are very pleased with the success of the operation and performance of both the equipment and our experienced offshore technicians. The solution significantly reduced the planned installation time and had major cost saving benefits for the end user. This project is an excellent example of our capability to deliver bespoke solutions on similar projects.”
