Ship Hull Repair

Wet underwater welding provides an effective solution for many emergency and temporary repair applications where immediate intervention is required. Performed directly in the water, this method enables rapid response to damaged structures, helping shipowners stabilise defects and maintain vessel operations until permanent repairs can be completed where necessary.

Our experienced commercial divers perform wet welding using proven underwater welding techniques in accordance with approved repair procedures. Depending on the nature of the damage, wet welding may be used for crack repairs, structural reinforcement, temporary steel repairs and emergency repairs across a wide range of vessel types.

Every wet welding project is carefully assessed to ensure the selected repair methodology meets operational requirements while maintaining the highest standards of diver safety and repair quality.

For permanent structural repairs requiring high-quality welds, Dive Marine Services utilises its proprietary Flexible Habitat Technology to create a controlled dry working environment underwater. This innovative solution removes water from the repair area, allowing certified welders to perform dry welding using conventional welding procedures while the vessel remains afloat.

Dry underwater welding offers significant advantages over conventional dry docking by reducing off-hire time, avoiding unnecessary deviations and allowing vessels to remain within their trading schedule wherever feasible.

Successfully deployed on technically demanding projects around the world, Flexible Habitat Technology has enabled Dive Marine Services to complete class-approved repairs including stern tube seal renewals, hull steel renewals, structural repairs and other complex underwater welding applications that were previously only possible in dry dock.

No two underwater repairs are identical. Every vessel presents unique engineering challenges influenced by its design, the extent of damage, operational schedule and classification requirements. As a result, many repairs require bespoke engineering rather than standard repair procedures.

Our engineering team works closely with vessel owners, technical superintendents, classification societies and original equipment manufacturers (OEMs) to develop practical repair methodologies tailored specifically to each project. From fabricated steel inserts and doubler plate installations to structural reinforcement and specialised underwater welding procedures, every repair solution is designed to restore structural integrity while maintaining the vessel’s operational schedule wherever possible.

By combining engineering expertise with decades of underwater repair experience, Dive Marine Services delivers innovative repair solutions that reduce downtime while ensuring the highest standards of safety and quality.
