At Diveworks International Ltd, we operate as a leading diving contractor in the UK and overseas. We deliver specialist wet welding and underwater fabrication services across all environments.
Additionally, our experienced team of coded commercial diver‑welders is equipped to undertake complex subsea welding operations. Therefore, we provide safe, efficient, and fully compliant solutions for marine and offshore infrastructure projects.
From underwater structural repairs to full subsea fabrication and installation, we support clients across the UK with high-quality, reliable welding services in demanding environments.
As a commercial diving contractor in the UK, we provide a complete range of wet welding and subsea fabrication services. This includes:
♦ Wet welding (subsea welding using direct current techniques)
♦ Subsea fabrication and installation of steel structures
♦ Underwater burning and exothermic cutting
♦ Structural reinforcement and repair of marine assets
♦ Modification of submerged infrastructure
♦ Surface preparation, inspection, and weld-ready cleaning
Furthermore all works are carried out by qualified diver-welders in accordance with HSE and IMCA standards, ensuring integrity, durability, and full regulatory compliance.
Our welding services are designed to support projects in:
♦ Ports and harbours
♦ Offshore energy installations (including wind and oil & gas)
♦ Marine civil engineering works
♦ Bridges, quay walls, and subsea structures
♦ Inland waterways and confined environments
However, we also understand the complexities of working subsea, including reduced visibility, tidal influences, and access constraints. As such, we implement strict planning, risk management, and safety procedures to ensure high-integrity welding outcomes in high-risk subsea environments.
