Passage planning guide SOMS

[Code: WITH 213]
Hardcopy only

This publication provides passage planning guidance for Masters and navigating officers when transiting the Straits of Malacca and Singapore.

The guidance applies in either direction through the Straits between One Fathom Bank (OFB) and Horsburgh and includes an overview of the navigational references for each leg of the route. It is suitable for all classes of ship.

This new edition has been fully revised to incorporate the latest guidance and practical advice for ships transiting the region, with reference to high vigilance areas, Straits Pilot Services, TSS and VTS information. It also includes a tidal streams supplement booklet containing high quality diagrams to provide mariners with information about the tidal conditions they are likely to encounter during their transits through the Straits.

The Guide illustrates areas where high vigilance is required and lists the pre-emptive measures that should be taken by the ship. These areas have been revised and expanded, with input from the pilots who regularly navigate these challenging areas, to include the area around Muda Selatan. Also included are a number of case studies that examine the causes of various groundings and collisions in the Straits.
