What are Points To Be Kept In Mind during Passage Planning?

  • Maximum permissible loading draught by the Company is restricted to 20.50 meter, while transiting the Malacca / Singapore Straits
  • Follow Local regulations as per Rules for the Straits of Malacca & Singapore Straits
  • VLCCs on her laden voyages can pass BUFFALO ROCK (Singapore) during the Daytime High Tide only.
  • Minimum allowable UKC to maintain when passing entire passage is 3.50 meter (One Fathom Bank and Buffalo Rock),

EXCEPT when passing EASTERN BANK, in the season of North-East Monsoon at the South China Sea, where Minimum allowable UKC to maintain is 4.00 meter.

Tidal window

Where the waters are affected by large tidal variation, adequate UKC may sometimes be attainable only during the period that the predicted tide has achieved a given height and vessel would need to wait for the suitable time to Cross the Bar.
