Production capacities

Marketex Offshore Constructions is your reliable partner in providing complex turnkey solutions for the offshore oil and gas industry. We manufacture structures from carbon steel (including HARDOX and WELDOX), stainless steel and aluminum. Hydraulics, electrical, piping, outfitting and lining are part of the services performed on turnkey projects.

Over 400 of our highly qualified staff, including indirect labor, are working in 7 production workshops with a total area of more than 28 500 m2. All of our welders have certificates by major Classification Societies and/or DVS (German Welding Society).

All workshops are equipped with a wide range of welding and other types of machines. Within our production workshops we are capable of producing large and heavy steel and aluminum structures or other elements with dimensions up to 32m in height and 22m in width. We are also equipped with a 120 m long covered slipway where we are capable of producing floating constructions of up to 1 100 tons of weight.

Facilities and Capacities
