Detailed Description :

Background :

The scope included a review of the Camelot CB platform to determine the scope of work for the removal of all hydrocarbons and decommissioning of the platform for the HLV contractor to remove the topsides and jacket. The pipelines and wells had been previously disconnected.

The work consisted of the detail review of all equipment on board, determining what hydrocarbons remained and developing procedures for the removal of all hydrocarbons and the cleaning of the equipment. Equipment had to be cleaned to such a degree that the platform could be brought onshore for disposal without presenting a hazard to the environment. In addition ode produced a plan for the overall decommissioning project. A HAZID and HAZOP addressed the risks associated with the lifting and removal of equipments as well as the potential to produce explosive atmospheres.

ode was responsible for all off-shore supervision of the decommissioning process and produced detailed work-scopes and detailed job cards for offshore implementation including:

• The removal of submersible pumps
• Cutting of the caissons
• Isolation of process equipment
• Testing of Padeyes
• Phased removal of the control and telecommunications system to allow remote watch during periods when platform was unmanned.
• Phased removal of the electrical system, Navigational Aids and safety equipment; ensuring platform conformed to the safety case up until the point of removal.
• The sea fastening of all remaining panels, generator exhausts and loose equipment.

ode was responsible for closing out all of the offshore workpacks and producing completion certificates to demonstrate that all of the work had been undertaken correctly and completed satisfactorily.

A detailed inventory including types of material, weights and coatings of all steel, pipework, electrical and instrumentation equipment, cladding, insulation etc was produced to ensure that as much as possible would be recycled by the disposal contractor.

Although the jacket and platform was transported to Teesside ode prepared detail plans and located potential sites in the Great Yarmouth area where the jacket and platform could have been landed and stored. This required discussions with the local councils, port authority and environmental agencies.
