passage planning

Witherbys maintains relationships with Maritime Administrations, Port Authorities and Pilotage Authorities/Organisations to continually develop and update comprehensive Passage Planning Guides to:

Baltic Sea

Great Barrier Reef and Torres Strait

English Channel, Dover Strait and Southern North Sea

Turkish Straits

Panama Canal

Straits of Malacca & Singapore

Suez Canal

Each of these publications is updated on a regular cycle through workgroups involving Port Authorities, pilot groups, industry representatives and shipping companies. Each workgroup will meet ahead of the update to reflect on changes to regulations or AtoNs in their area and the resultant impact on routing.  During the update cycle, Witherbys' technical advisory team will undertake passages on board merchant ships to verify changes and discuss issues with the officers regularly transiting each route.

Passage Planning Guides for other regions are currently in development.
