Our solutions for offshore and shipbuilding.

Steel quality that breaks waves.

Steel plays a central role in the construction of new passenger and commercial ships, yachts and offshore facilities such as production platforms, drilling rigs and FPSOs – but also in repairs and conversions. UnionStahl is your reliable partner when it comes to meeting the highest quality standards in offshore and shipbuilding.

Steel with its high-performance properties is the most important Steel grades for the construction of new cruise ships, yachts, large container ships and tankers, and is also used for repairs and conversions. The construction requires thin sheets with large widths and excess lengths that are easy to weld. You will find these in our portfolio of normal-strength and higher-strength shipbuilding steel grades.

Foundation and construction of offshore facilities

Offshore installations are structures for the extraction of gas and oil, such as production platforms and drilling rigs. As the deposits of crude oil and natural gas in the open sea are difficult to access, the steel grades used must be suitable for low temperatures and be characterized by high toughness values.

The installation vessels required for the foundation and construction of offshore facilities also need these Steel grades properties. Jack-up vessels are a special type of installation vessel characterized by their hydraulic legs (jack-up rigs). These legs allow them to position themselves at a fixed location independent of the seabed. This enables them to work in deep water.

Other ships used to extract oil and gas are FPSO (Floating Production Storage and Offloading) ships. They take the oil and gas from the offshore installations, process it and pump it onto tankers for shipment.

With our extensive stock of offshore steel gradesand our capabilities for mirror cutting and close tolerance production, we are your qualified supplier. The stored Heavy plates fulfill the options of EN 10225 product analysis (option 5), CEV and _Pcm (option 8), stretch ageing test (option 11), tensile test in thickness direction Z35 (option 12) and information on weldability (option 17).

As a reliable partner for offshore and shipbuilding solutions, we have adapted to the high requirements with our full range of products and tailor-made services:

• Plates in shipbuilding steel grades 3.2 certified by all common inspection organizations
• Bulb Flat Steel Profiles
• Offshore steel grades according to EN 10225 and Norsok MDS-120 with options 12, 13 and 18
