Key facts

Offshore logistics covers all the work needed to ensure that construction proceeds smoothly, safely and on time.

Construction management covers a wide range of services including contract management, health and safety and marine coordination. In many cases contractors are embedded in the construction management team, and this may include sole traders. In addition, to fulfil the insurer’s requirements, a marine warranty surveyor (MWS) has to be appointed. The MWS ensures that all activities are compliant with the approved procedures and delivers the Certificate of Approval.

Specialist software tools are available to plan and monitor offshore activity.

Weather and metocean forecasting services provide visibility of weather windows a few days in advance. While meteorological buoys are typically owned and operated in the UK by the Met Office, third-party providers with their own forecasting algorithms also offer services.

Support vessels include guard vessels (potentially drawn from local fishing fleets), CTVs and accommodation vessels. These vessels may be contracted by the developer or the marine contractor.
