Decommissioning

Having successfully completed structural engineering analysis, design, coordination and CAD detailing for decommissioning, de-complexing and simplification projects on a variety of ageing offshore gas platforms within the Southern North Sea, Pinnacle have built significant knowledge and expertise in providing cost effective, innovative and intelligent structural engineering solutions whilst maintaining the highest standards of safety.

Safe solutions

Working closely with clients Pinnacle align themselves with the owner/operator’s desired objectives and drivers in order to ensure the most appropriate and safe structural removal methods (piece small, modular, single lift) as well as the longevity and life span of the retained structures, where appropriate. Benefiting from experience in the brown field arena Pinnacle use continuous learning to find the best solutions, with minimal waste (time and material). In addition to detailed engineering Pinnacle also provide project front end concept design studies offering different alternatives, along with recommendations, for the structural works. This can be invaluable in building a robust plan.

Specialised knowledge

Pinnacle has valuable and specialised knowledge and is ahead of the market in working within ageing assets on de-complexing and simplification projects as well as the structural engineering preparation for total decommissioning.

Significant offshore experience

Completed projects have included the removal of major structural items from ageing platforms ranging from and including total and part deck removals, helidecks, plant, equipment, flowlines, vessels, cranes, vent masts and accommodation modules. Where platforms were to be maintained, following a radical simplification approach, Pinnacle have designed and fully detailed extensive refurbishment, replacement and repairs to the retained platform topside structures including walkways, gratings, stairs, handrails, deck support steels, pipe supports, boat landings, blast walls and the support and installation methodology for hybrid power systems.

As well as cutting edge design solutions, Pinnacle’s significant experience and expertise helps to ensure that your project will be fully coordinated and planned for smooth delivery of the structural engineering thereby saving programme time and money.
