In the case of an emergency, our expert divers can be on-site within hours to help get your operations back on schedule as soon as possible. We also offer comprehensive preventative maintenance and routine work on vessels of all sizes.
Inspections & Surveys & Repairs
We use the latest imaging technology to carry out surveys and can provide still and video CCTV footage to give you a clear picture of what is happening to your vessel. For discovered or existing defects, RS Divers can also replace hull fittings, cut off and weld on fittings and panels, and undertake most repairs that do not require dry docking.
Propeller & Thruster Clearance
From basic prop clearance to removing a bow thruster grate, clearing any debris, and replacing the grill, RS Divers can cover all of your propeller needs and be on-site within three hours.
At RS Divers, we can fit any type of anode in water to save on dry docking costs. We have access to coded welders, too, if this is required.
Discharge & Intake Blanking
We have a variety of standard-size and custom-built bungs and coffer dams to blank off any inlet or outlet to enable ships’ engineers to undertake repair works without the need for dry dock.
Our multispeed hydraulic power packs enable us to use any kind of tool required to clean even the most stubborn of growth from propellers.
Our Shipping Work
Our recent work includes:
- Cutting off the rudder from a large merchant ship in Southampton.
- Replacing underwater cables on a survey vessel in Lowestoft.
- Inspecting the hull of a survey vessel for new owners in Shoreham.
- Blanking outlets on an RN warship in Hull.
- Supporting blanking work on the Queen Elizabeth Carrier in Portsmouth Harbour.
- Carrying out underwater hull surveys in Portland.
- Freeing ROVs from the propellers/shafts of cruise liners etc.

How do you weld underwater?
Welding underwater, also known as underwater welding or hyperbaric welding, is a specialised and challenging process used for various applications such as repairing underwater structures, pipelines, and offshore platforms. There are two main methods for underwater welding: wet welding and dry welding.
Wet welding, the more common and straightforward method, involves welders working underwater with specialised diving gear and waterproof welding equipment to create a shielding gas around the weld area, protecting it from water contamination. It is often used for temporary repairs or when setting up a dry welding environment is impractical due to cost or complexity.
Dry welding, also known as hyperbaric welding, is a more complex and costly technique that occurs in a sealed, pressurised chamber, eliminating the risk of water contamination and allowing for high-quality welding.
The choice between wet/dry welding depends on factors like the specific underwater welding application, budget constraints, and the desired level of quality. Underwater welding is a highly skilled and hazardous profession, and welders must undergo training and certification to ensure safety and proficiency.
What do you use anodes for?
Anodes are essential for cathodic protection on ships, a method designed to prevent or reduce the corrosion of a ship’s metallic hull and submerged metal components. This process is necessary because ships spend considerable time in corrosive saltwater, leading to galvanic corrosion, where metals like steel rust as they release electrons into the surrounding water.
To safeguard critical ship components, sacrificial anodes made of materials like zinc, aluminium, or magnesium are strategically attached to the hull and other submerged parts. These anodes corrode intentionally instead of the ship’s metal, releasing electrons and creating a cathodic effect, which effectively prevents corrosion. However, anodes are not permanent and require periodic replacement, depending on factors like water quality and anode size, necessitating regular inspections and maintenance to ensure continued protection.
