From non-structural underwater welding and underwater demolition all the way through to advanced coded structural underwater welds. Our Deep Bight Marine team of experts can professionally do it all.
If you need an underwater welding or cutting requirement on your project, get in touch with our friendly team today for expert solutions and advice.
Deep Bight Marine are the experts in underwater wet-welding. We are equipped with the latest welding technologies and are strategically positioned to deliver outstanding results for our clients.
Wet welding involves the use of shielded arc-welding techniques by a highly qualified diver/welder.
The welding system is specially designed for subsea use, including fully-insulated cables, hand-pieces, and electrodes.
To ensure our diver’s safety, we only use DC current in performing wet welding, with a knife-switch breaker employed on the surface to allow the dive supervisor to immediately cut the current flow as required.

Deep Bight Marine specializes in underwater demolitions using the powerful Broco® underwater cutting system.
Broco® thermal lancing is the most efficient & cost-effective means of completing almost any form of underwater cutting, gouging and piercing operations.
Utilizing extremely high cutting temperatures (5000c), Broco cutting allows the diver to easily cut through any material including concrete, steel, wood, and rock.
These rods cut through marine growth, rust, and mill scale, eliminating the need for pre-cleaning and helping to lower operating costs and reducing bottom time.
Passing a DC current of approximately 150A through the insulated system to the diver along with a stream of pressurized O2 which increases appropriately with depth, with the use of an isolation knife switch, the supervisor can disengage the current and the diver can continue cutting as soon as an arc is achieved, keeping the diver safe and minimizing risk of electric shock.
