Proposals that require static sea surface infrastructure or that significantly reduce under-keel clearance must not be authorised within International Maritime Organization routeing systems unless there are exceptional circumstances.
1. This policy focuses on proposals that result in static infrastructure that may have a presence at the sea surface and/or may reduce keel clearance to the extent that it will impact on vessel traffic.
2. Proposals should show that they have consulted with the Maritime and Coastguard Agency to define ‘significant’ reduction of under-keel clearance in relation to their proposal during the scoping process.
3. The policy does not preclude non-permanent static sea surface infrastructure eg jack-up vessels, which are subject to operational requirements such as notifications to mariners to ensure safe operation.
