Marine Aluminium AS is an internationally recognized supplier of innovative and sustainable access solutions. Since 1953 Marine Aluminium has been designing, manufacturing and supplying in aluminium to satisfied offshore, marine and onshore clients.

Marine Aluminium AS produces Accomodation Ladders, Turn-Key Helidecks, Gangways and Friction Stir Welded Panels (FSW).

FSW Panels offer substantial benefits. The flatness of the panels, free from distortions and buckling will ensure the highest efficiency during fabrication and this will save man-hours/cost and improve quality. The technology has been approved by all major classification societies. Marine Aluminium AS has been approved and issued with the certificates covering the FSW machine and method. Our highly automated FSW machine makes it possible to weld large size panels up to 15 meters in length. The alloys used are all seawater resistant and have the mechanical strength of mild steel at roughly 1/3 of it’s weight.

The solutions we offer can be tailor made to suit the customer’s requirements.

Marine Aluminium AS has a unique competence in producing large modularised panel systems for both the superstructure and hull of ships. The panels are produced by Friction Stir Welding of large aluminium profiles, rather than the more traditional methods based on manual welding of sheet metal.

The absence of melting during welding gives a modularised panel free from thermal distortions, and with a plane and smooth top surface. There is no need for after work such as grinding and brushing on friction stir welded panels. This results in a process that is cheaper overall with substantial weight reductions and an end product with a superior finish.

Typical use for FSW panels are:
• Ship hulls and superstructure
• Elevator shaft and stair tower walls
• Modules
