Your job is not on the list?
Describe in a request what needs doing on or under water. We will tell you whether we take it on and how.
What the price of diving work depends on
There is no ready price list for underwater work. Similar jobs cost differently on different sites, so we price each job on its own.
- The kind of work. An inspection with a video report, hull cleaning, welding or raising a sunken vessel each take a different crew, equipment and time.
- The scope. The hull area to clean, the length of a pipeline route, the number of piles or stations to inspect.
- The depth. Dives below 12 m go under a certified diving physiologist, with our own decompression chamber for a working pressure from 1 MPa.
- The site. Current, visibility, the seabed and the rules of the harbour decide how many divers work and how long a dive lasts.
- The reporting. Photo and video, the ON-LINE TV feed, depth maps, a report for the classification society.
What to tell us to order a diver
The more we know about the job, the closer the estimate. Photos and documents are easiest to send in a messenger.
- What the object is: a vessel, a berth, a pile, a pipeline or a cable.
- Where it is and at what depth the work is.
- What needs doing and what report you need, for yourself or for the classification society.
- When the work should start and by when it should be done.
- Photos, drawings or earlier reports, if you have them.
