Confined Spaces

Our experienced team of divers and marine civil engineers are qualified to perform services in a wide range of confined spaces, both at sea and on land.

Our Services

RS Divers has fully trained confined space teams able to mobilise at short notice to undertake inspection and remedial works in confined spaces such as tanks, culverts, tunnels, sewage tanks and outfalls. We have access to the latest underwater Remote Operated Vehicles (ROVs) to use in pipelines and outfalls too small for a diver to enter.

Here are some of the services we provide:

Underwater Confined Space Services

We perform inspections, surveys, maintenance, repairs, welding and construction projects in a variety of confined spaces, such as:

Our Confined Spaces Work

Our recent work includes:

What is a confined space

A confined space is a relatively small or enclosed area with limited access and egress, not designed for continuous occupancy, and where potential hazards may exist due to its design or contents. 

These spaces can be found in various industrial, construction, and manufacturing settings and may pose significant risks to workers or anyone entering them. Confined spaces can be dangerous due to factors such as restricted ventilation, the presence of hazardous substances, and limited escape options.

Some common examples of confined spaces include:

  • Tanks and vessels
  • Manholes and sewers
  • Boilers and furnaces
  • Tunnels and pipelines
  • Pits and trenches
