Custom Offshore Steel Fabrication & Welding Services

Wind, Marine, Oil & Gas, and Civil Engineering Solutions

Weldmetcon is a specialist offshore steel fabrication and welding company, delivering custom-engineered steel structures for the wind energy, oil & gas, marine, and civil engineering sectors. From structural design to final installation, we provide end-to-end offshore fabrication services built to perform in the most demanding marine environments.

Offshore Wind Farm Steel Structures & Fabrication

As global demand for renewable energy grows, offshore wind farms are expanding rapidly — with larger turbines deployed further out to sea. These projects demand precisely engineered offshore steel fabrication, from turbine support structures to specialised transport and installation equipment. Constructing these energy systems requires meticulous planning and robust, custom-fabricated steel structures for both the turbines themselves and the vessels that transport them.

Weldmetcon’s offshore wind fabrication services include:

  • Sea fastening frames – secure steel frameworks mounted on vessels to stabilise equipment and components during maritime transport
  • Wind turbine component storage – custom steel structures for safely storing and transporting turbine parts, including blade racks and assembly frames
  • Grillages – heavy-duty offshore foundations engineered to support turbine installation in challenging seabed conditions
  • Decommissioning structures – fabricated solutions for the safe and efficient dismantling and removal of offshore wind platforms and foundations

Offshore Oil & Gas Platform Fabrication & Decommissioning

Despite rapid growth in renewables, the oil and gas sector retains extensive offshore infrastructure that frequently requires upgrades, structural repairs, or decommissioning support. Weldmetcon provides steel fabrication services for offshore oil and gas platforms throughout their full operational lifecycle — from active service through to safe retirement.
Our oil and gas fabrication services include:

  • Sea fastening frames – protective steel frames engineered for the secure marine transit of heavy offshore equipment
  • Platform construction & components – railings, gangways, cranes, walkways, support frames, boat landings, transport supports, and flare systems
  • Offshore storage solutions – custom racks, containers, and bunkers for specialised platform and vessel needs
  • Decommissioning fabrication – engineered steel structures for the safe disassembly and removal of obsolete offshore platforms and foundations

Offshore Marine Vessel Refit & Steel Fabrication

Refitting or upgrading an existing vessel is often a more cost-effective solution than a new build. Weldmetcon partners with vessel owners and operators to overhaul, upgrade, or refit marine vessels for new roles through bespoke steel equipment and custom-fabricated installations.

Our marine fabrication capabilities include:

  • Vessel equipment & machinery – winches, sheaves, railings, walkways, cranes, stairways, conveyor systems, suspended frames, boat platforms, transport frames, and flare systems

  • Specialised offshore storage structures – dosing hoppers for fallpipe vessels, custom cargo racks, and offshore storage bunkers

  • Subsea steel structures – grillages and heavy-duty steel frameworks engineered for underwater and subsea operations

  • Sea fastening solutions – custom steel frames to secure heavy loads safely during marine transport

  • Salvage fabrication – custom lifting frames and barge constructions designed to support heavy lifting and marine transport operations

Offshore Welding Steel Constructions

Offshore Civil Engineering Steel Structures & Support Systems

Temporary or permanent custom steel structures are often critical to the success of large-scale civil engineering projects — providing foundational support, enabling safe access, or facilitating essential structural maintenance.

Weldmetcon delivers innovative, project-specific steel fabrication solutions for:

  • Bridge support structures – temporary and permanent steel support systems engineered for bridge construction, repair, and maintenance projects

  • Jetty & pier construction – custom steel frames and structural components for the creation or restoration of jetties, marine access roads, and bridge links
