Project Background

BP Valhall Accommodation/Hotel Platform Project

The Valhall platform is located in the North Sea off the coast of Norway and is one of the largest offshore brownfield projects ever attempted across the globe. The $2.4billion project was to build a new accommodation/production platform, preserving a proportion of the existing infrastructure which was pending eventual decommissioning and to stop reservoir subsidence in order to extend field life to 2049.

The new production and hotel platform – has a design life of 40 years. It is sized for production of about 120,000 barrels of oil and 143million cu ft of gas per day; water handling capability of 200,000bpd; a topsides weight of some 16,000 tonnes, and jacket weighing in at 7,500 tonnes.

Project Details
Working with renowned SLP Engineering, Gooding Aluminium were contracted to supply aluminium wall cladding Type WC2, combining perforated and plain aluminium sheets, for the atrium accommodation facilities module (Perforated Aluminium Sheet GA P1632 & Plain Aluminium Sheet GA 1539).

The living quarters house 180 people, they are powered from offshore for additional energy efficiency, but more importantly, the Gooding Aluminium lightweight, powder coated finish perforated sheets weigh 1.38 kg/m2, and the plain aluminium sheets are 5.5 kg/m2. The lightweight nature of the panels helped to bring the platform within the specified weight limit, contributing to the ongoing subsidence control programme.

In total, over 950 aluminium panels were supplied, manufactured and delivered in 4 stages. Each stage delivered ahead of schedule and once again celebrated Gooding Aluminium’s enviable 100% quality control, whereupon no panels were rejected.


“I chose the Goodings system in preference to a variety of acoustic linings for the following reasons:-
a. Weight/performance met our strict criteria.
b. Reasonably easy to be installed by abseilers i.e. the fixing method and durability provided perfect product.
c. Cost
d. Repairable paint finish
e. Contractor experience of GA.
f. Crisp precise detailing and the system allows acoustic and non acoustic panels in the same coherent system.”

Aluminium awareness information
Key Facts:

  • Aluminium is great for incorporating into weight sensitive applications, such as this one.
  • Environmentally friendly aluminium is the only recyclable material that more than pays for it’s own recycling costs!
  • Recycling aluminium into new forms only requires 5% of the energy that originally produced it.
  • All manufactured aluminium is effectively a stored energy bank for future generations.
  • Aluminium is only 1/3rd the weight of steel.
  • Aluminium’s surface has a self generating and repairing oxide coating which makes it corrosion resistant and therefore less expensive to maintain than steel and other corrodible metals.
