Diving and underwater engineering

Spotlight

A multi-level, deep-water loch provides the perfect training conditions for diving and remote-operated vehicle piloting.

The Underwater Centre at Loch Linnie, Fort William, offers conditions and depths similar to those in the North Sea making it an ideal test bed for sub-sea equipment and technology. Last month Adus, a group based at the University of St Andrews, used the site to test a new sonar deployment system, which enables the group to produce accurate site plans and make comprehensive assessments of submerged archaeological sites, such as wrecks and crashed aircraft.

Earlier this year Invent Water Features installed what is believed to be the highest seawater floating jet fountain in the world, in Dubai. Underwater maintenance and repair specialists, UMC International, were recently brought in to carry out underwater paint coating repairs on the fountain.

UMC's Dubai office branch manager Simon Doran said that after identifying the area with paint abrasion damage and removing the marine fouling, UMC prepared a sacrificial pretreatment brush before applying UnderC 11SW solution in two coats to the damaged areas.

A diver prepares to enter the water to begin an hour-anda-half stint of laying cables off the coast of Denmark. The project was carried out earlier this year by underwater specialist Falmouth Divers on the world largest wind farm:

Horns Rev. Working in shifts was limited to an hour and a half because of the unusual conditions of working in open water.

The divers laid interconnecting cables that linked each turbine in the array together. A single transmission cable then linked the wind farm with the shore, aiding Denmark's drive for renewable energy.
