Our divers are trained to identify and report hull conditions such as paint blistering, corrosion, fouling and superficial structural damage. We also inspect, cathodic protection systems, bilge keels, sea chest, strainers along with propellers, exposed shafting and rudders.

We can provide a comprehensive hull survey report for shipping companies and for Ship Classification Societies as we are certified to perform class surveys for Lloyd’s Register, Det Norske Veritas (DNV), Bureau Veritsas (BV), Rina and American Bureau of Shipping (ABS) and have carried out inspections to the specifications required.

All discrepancies are recorded on tape and provided to the client with a written report upon request.  Underwater color CCTV or video camcorder services are available for hull inspections if requested. Our equipment and expertise has a wide range of applications in a wide range of circumstances not at first associated with diving.

3. Salvage

From a shovel to a ship” sums up the range of objects and vessels we have salvaged, recovered or re-floated. We have lifted water-carrying vessels whose weight exceeds the 1000-ton mark and have carried out minutely painstaking search and recovery operations for highly valuable small items.

Most recently we carried out the salvage of AST 23 of Overseas AST in Abu Dhabi, U.A.E. This was a careful recovery and represented a difficult logistical problem under the harsh scrutiny of the World’s press and local authorities and environmentalists, working closely with Oil Spill Prevention teams.
We have also recovered valuable cargo and items on behalf of owners and have lifted such disparate objects as:


  • Sunken dockyard cranes.
  • A statue.
  • Aircraft.
  • Mobile cranes.
  • Articulated HGV's.
  • Fishing boats and vehicles.

 


We own a large array of salvage gear such as pumps, lift-bags, cutting gear, patching equipment and tools and can mobilize as quickly as is needed to an emergency via our genuine 24hr callout procedure.

4. Video/Photography


We are equipped to carry out all types of underwater and confined space inspection projects as we own an inspection ROV, underwater video systems and underwater stills photography cameras. We can produce good quality prints, slides, video and reports under most conditions. The video system are operated from 8 feet by 8 feet air-conditioned containers with lighting and built in power. The advantage to the client of being able to see exactly what the underwater situation is at any time on his site is an enormous advantage that can save time and money on subsequent works.
