Hidd Pipeline Project - Bahrain

Kraken played a very important role on the HIDD project in Bahrain carried out by a Joint Venture of Christiani & Nielsen & Nass Contracting. Kraken was specified to transport a proportion of the pipes on the surface as well as to provide underwater lightening buoyancy to reduce the winch load on the 4km x 4 pipes bottom pull.

A most unfortunate fatal accident with the winch in the early stages of the pull resulted in a complete change of method which involved the Kraken being used exclusively to not only transport all the pipe to the lay position up to 7km away, but also to hold it on the surface while it was welded as well as perform the controlled sinking into 5/7m of water.

While not without some problems, Kraken performed this quite unexpected and un-planned task, and 5 months later the contract was completed using no other form of pipe transport or control whatsoever.
