Marine Aluminium - Aluminium Helidecks, Gangways, Offshore Modules and Safety Systems

Marine Aluminium is one of the world’s leading companies within engineering, design and fabrication of aluminium structures and products for the offshore and shipbuilding industry, as well as other segments. After more than 50 years in the business, we have particular competence in the fields of material technology, extrusion tooling and welding techniques.

Extensive knowledge and experience are decisive factors in our ability to supply products of a consistent quality. Modern production facilities, highly skilled personnel and a network of partners ensure that results comply with all specifications and requirements.

Marine Aluminium is located on the west coast of Norway, with easy access to the open sea. Our site includes spacious indoor facilities for building and assembling a wide range of products, as well as a deep water quay with the possibility to load out large structures and modules.

ALUMINIUM HELIDECK SYSTEM

Marine Aluminium is the world's leading producer of aluminium helicopter decks. Our decks can be tailor made to fulfil the customer's requirements - the delivery can range from a package for container transport to a completely installed turn-key helicopter deck including lighting, fire fighting and more.

Aluminium helicopter decks offer substantial benefits over other materials. This make them particularly suited to marine, offshore and other weight-sensitive structures.

The alloy used for helidecks has the same mechanical properties as mild steel and merely one-third of its weight. In addition, the extrusion technology provides the designers with possibilities that are impossible with steel. The aluminium alloy used also requires less maintenance, due to its corrosion resistance.

With more than 400 decks installed from the first in 1974, customers include: DONG, BP, Modec, StatoilHydro, Petrobras in the offshore field, Aker, Vulcano, Samsung, Kleven and many other shipyards.

TELESCOPIC GANGWAYS

Our telescopic gangways provide a very important safety feature, and are widely used for personnel access between offshore installations. An additional feature is that the gangway can support transfer lines for fuel, mud, electricity, water and more.

The gangway can be used to bridge fixed and floating installations and also between two floating installations.

The telescopic bridge ensures the safety of personnel even during the roughest conditions, as the bridges also have automatic disconnection in the event of an emergency. Customers include Prosafe, Odfjell Drilling, StatoilHydro, Haliburton, Sedco forex, Seatruck Group and many others.

OFFSHORE MODULES

Marine Aluminium can supply a wide range of custom built offshore modules complete with design, engineering and production services. Our offshore modules can be used for various purposes such as:

• Accommodation
• Office space
• Recreational areas
• Workshops
• Containers
• Storage areas
• Control room modules
• Heli-guard areas
• Helicopter hangars
• ROV hangars
• LER/LIR

All modules can be supplied ready outfitted and insulated to any fire-rating. Low weight makes installation easier by reducing the amount of work required offshore. The modules can be fully outfitted and still be lifted using existing cranes on the installation.

Customers include StatoilHydro, Leirvik MT, Aker Solutions, Stena Drilling, Shell, Aibel and many others.

FRICTION STIR WELDING

This unique process makes it possible to weld extruded aluminium profiles through friction heating without the need for either shielding gas or filler metal. The lower heat required for welding the profiles means less distortion, and the technology produces panels with better mechanical properties than fusion welding.

By welding many profiles together, one can produce panels up to 20m in width. Using certified aluminium alloys and welding speeds in the process, the surface of the resulting panels is smooth, and requires no further grinding or brushing to improve the finish.

Marine Aluminium has one of very few commercial machines for friction stir welding in Northern Europe. Continuous technology improvements in recent years have resulted in improved welding speed, logistics and QA systems. The FSW machine is capable of manufacturing panels with a maximum size of 16m by 20m and thickness from 1.8mm to 12mm.

HANDRAIL SYSTEMS

Marine Aluminium has developed a site-built railing system based on our former SAR system. The new handrail system is highly versatile and can be adapted to any structure.

The reasons for using site-built railing systems are minimum weight, easy installation and easy modification work. The system can be installed offshore without any hotwork.

FLEXIBARRIER SAFETY SYSTEM

FlexiBarrier is especially developed to cope with rough handling of goods and containers offshore, and consists of hinged and energy-absorbing posts and horizontal railing with flexible interconnection.

The system’s unique design, low weight and high corrosion resistance offer great advantages over comparable steel constructions.

FlexiBarrier is delivered with footplates for either welding or bolting to steel or aluminium decks, and the railing can be supplied in different heights and with an optional number of rails. FlexiBarrier can also be extended to a larger flexi-wall structure.
