Decommissioning Power Supply Installation

The Project

A 40m bridge link was constructed to facilitate the decommissioning scope from the walk to work vessel. Pre-mobilisation, Dron & Dickson assembled a range of flying leads with pre-terminated hazardous area connectors allowing for rapid connection and disconnection. Junction boxes were pre-terminated with connector interfaces in advance of the vessel mobilisation to allow quick connection once in situ. This ensured power was available for decommissioning scopes to commence rapidly and safely.

• Dron & Dickson engaged with a number of manufacturing partners in advance of the scope to ensure the optimum products were utilised and were appropriate for each power application.
• Reduced distributor terms were provided through Dron & Dickson for all sourced cables, glands, connectors and consumable products.
• All flying leads were pre-terminated with connectors onshore at Dron & Dickson’s facility by competent time-served Technicians.
• Offshore installation was provided by Dron & Dickson’s Engineering Services Team.

The Result

Utilising this system, the operator reduced the amount of time required for the walk to work vessel, subsequently significantly cutting decommissioning costs. Further time and cost savings were also realised by the reduction of offshore installation time from alternative cabling and glanding.

The NUI was successfully decommissioned on time and under budget.
