The Port Authority issues Local Notices to Mariners (LNTM). Upon issue these are published on the Port website, and notified to all pilots authorised by the Port Authority, all current Pilot Exemption Holders (PEC) holders and Masters of vessels regularly visiting the port who are not subject to compulsory pilotage. Where relevant, shipping agents are also included so that they are alerted to any relevant changes.
