11.1 To the extent practical, States and port
authorities should aim to ensure smooth flow of ships going in and
out of their ports to avoid keeping ships waiting offshore so that
anti-fouling systems can operate as effectively as possible.
11.2 States may apply other measures on ships
within their jurisdiction for the purpose of providing additional
protection for their marine environment, or in emergency situations.
In managing emergency situations for biofouling, States should consider
the guidance document for ballast water emergency situations (BWM.2/Circ.17).
11.3 States should take into account these Guidelines
when developing other measures and/or restrictions for managing ships'
biofouling.
11.4 Where other measures are being applied, States
should notify the Organization of the specific requirements, with
supporting documentation, for dissemination to other States and non-governmental
agencies where appropriate.
11.5 The application of other measures by States
should not place the safety of the ship and crew at risk.
