AUK Alpha Platform, UK

Case Study

REPSOL SINOPEC RESOURCES UK

Auk Alpha Platform – Offshore North Sea

The Auk ‘A’ (Alpha) platform is an integrated drilling, production and living quarters facility supported on an eight leg jacket structure. The drilling derrick has since been removed. It was operated by Shell UK in 50% partnership with ESSO until October 2006 when it was bought by Talisman Energy, and is now licensed by Repsol Sinopec Resources UK Ltd.

 

PROJECT OVERVIEW

The client approached ICE when a number pipework failures within the offshore accommodation on board the AUK Alpha platform resulted in personnel cabins having to be temporarily closed off. ICE were commissioned to carry out an offshore survey. Our team used a borescope camera, discovering that both the black and grey drainage pipework was in a very poor condition. There were visible cracks and in some areas holes where the pipework had become corroded beyond repair. We submitted a detailed technical and commercial proposal offering a solution to the issues. The workscope was agreed and the project started in April 2020.

 

“I would like to say the effort from the guys has been outstanding and a real credit to ICE. They have first and foremost worked very safely, very conscientious and take a great deal of pride in doing a first-class job.”

THE SOLUTIONS

The decision was taken to replace all the black and grey water drainage pipework from level 1 to 3 that serviced the fourteen affected cabins. We installed high quality plastic drainage pipework and the associated fittings. Fire collars were installed at all penetrations between decks. The project also included lifting several tiled shower floors to access the floor drainage and replacing these areas with a new floor covering.

The project required the movement of night shift personnel to the adjoining PLQ cabins due to noise disturbance and the need for wet room access. This was managed in conjunction with the facilities manager. As part of the project, our team water jetted an existing part of the drainage system to remove any potential blockages.

THE TEAM
The project was planned, procured and managed by our onshore project team then executed by our offshore team. The offshore team included two plumbers and a floor layer.
THE OUTCOME
The work was completed over a six week period to minimise disruption. The project was completed on time, within budget and with no health and safety incidents.
