Cutting fire insulation costs

November 13, 1998, 08:00 CET

A new type of fire insulation for components offshore and on land offers Statoil annual savings of NOK 7-10 million.

Developed by the group together with Rheinhold & Mahla Isolering, this product is intended for piping, valves and other technical equipment, reports staff engineer Eivind Robert Oen in the core team for surface treatment.

Maintaining a number of components has hitherto been complicated by the need to remove a steel insulation capsule before work can be carried out.

The new solution functions as a kind of "insulating jacket" which is simple to remove and replace.

It comprises several layers of different materials. While the outer layers provide protection against wind, weather and fire, the inner ones help to maintain a stable temperature.

The insulation can be provided with inspection hatches which provide easy access to valves without having to remove the entire jacket.

This solution has been developed at a cost of NOK 1 million within the supplier development programme (LUP) pursued by the Industrial Development business area. Statoil and its partner shared the investment 50-50.

The group has initially adopted the new product on its Gullfaks satellites project in the North Sea, and it has also been purchased by Norsk Hydro for its Visund and Troll C installations in the same waters.
