Ballast Water Management
Despite strong tidal currents around the Orkney Islands, the inner waters of Scapa Flow are largely unaffected by tidal currents and consequently the water exchange process is very slow.
To minimize the potential for pollution resulting from oil, chemical, heavy metals and transfer of non native aquatic organisms and pathogens which may be contained within ships ballast water and associated sediments, the OIC Harbours in association with the Flotta Oil terminal, operates a stringent policy on the control and management of ships' ballast water; to provide protection for this important marine environment and the rich natural marine biodiversity within Scapa Flow.
The procedure applies to all vessels over 400GRT within or using the Scapa Flow Oil Port or Anchorage Facility. These port procedures enhance on the International Convention for the 'Control and Management of Ships' Ballast Water and Sediment' adopted in 2004, and the guidelines issued under IMO Resolution A.868 (20).
