Minimum manning, reduced costs and maximum safety
Some oil and gas installations need costly manned intervention to complete a variety of activities; primarily maintenance, modification, well services, inspection and fabric maintenance.
The amount of work required to complete inspection and maintenance activities on ageing assets, tends to increase with time.
Larger installations generally have accommodation and are manned throughout the year, but smaller installations tend to be normally unmanned (NUI).
These NUIs require engineers to be deployed by helicopter to deliver the required work. Longer interventions, particularly for NUIs, can require the support of large accommodation vessels at high additional costs.
