Offshore plates for oil & gas

Our offshore plates for the oil & gas industry are used worldwide under the harshest conditions. Living continuous development of new products to meet more stringent requirements, we are able to provide prequalified arctic steel for extremely low temperatures. Using toughcore® TMCP plates with extreme high toughness, you are able to increase the level of safety for your offshore structure up to 140 mm thickness.

High-strength plates

As structures and machines become larger, the stresses in the components increase. High-strength steels with minimum yield strengths of 700 MPa or even higher up to 1100 MPa are capable of supporting these higher stresses and simultaneously lead to a decrease in the weight of structural members.

Thermomechanically rolled high-strength fine-grained steels combine excellent toughness with a very low carbon content and the low carbon equivalent and for an optimized weldability.

Chords & racks

In addition to supplying heavy plates, heads and cones, we produce specific pressed parts for the offshore industry. In a specially designed production process, we manufacture high-strength hot-formed components called chords for jack-up rigs. Additionally we offer extremely thick plates for gear racks.

A high-quality package

We are a single-source supplier of shell plates, heads and cones made of plain carbon steel, in roll-bonded clad design and for sour service. 

Our answer to corrosion

Clad plates are the economic alternative to expensive high-alloy and non-clad plates. Roll-bonded clad plates are our answer to corrosion and explosion. 

With a cladding capacity of 60,000 tons a year, we are World´s leading producer of roll-bonded clad plates.

Heads and cones, high quality pressed parts

Offering shell plates, heads and cones from a single source, made of carbon steel and roll-bonded clad plates.

In our own Single-part and multi-part heads and cones, special pressed parts

We manufacture custom-made heads as a single part or welded from multiple parts. Multi-part heads and cones are available in head gauges of up to 160 mm and diameters of up to 14,000 mm.

We supply higher strength & lighter weight

alform® heavy plates find their applications wherever high workability and weldability coupled with high strength and weight savings are in demand. Utilization of the higher yield strength of high-strength fine-grained steels as opposed to conventional structural steels results in lower cross-sections. This leads on the one hand to cost savings in lower component weights as well as reduced expenditures for transports, assembly, foundations, component manufacturing, especially in welding as a result of minimized seam cross-sections.
