Towage Guidelines

Tug usage guidelines for vessel movements in the port of Singapore.

The tug assignment guidelines are intended to assist the port user to determine the number of tugs to be assigned to a vessel requiring the assistance of tug(s) to manoeuvre within the port waters of Singapore.

A vessel equipped with a suitable bow/stern thruster(s), in good working condition, may dispense with the need for a tug in that position. Owners, masters or agents of vessels equipped with thrusters must confirm the capabilities and performance of the thrusters at the time of booking for pilot and tugs. Notwithstanding the above, the number of tugs required is determined, among other factors, by the size and shiphandling characteristics of the vessel, the peculiarities of the berth and its approaches, and the prevailing conditions e.g. tidal streams, wind and weather. The pilot upon boarding may thus, in consultation with the shipmaster, cancel or order additional tugs.

For operations purposes, harbour tugs are classified under 4 categories depending on their bollard pull:

  1. 10 to 16 tonnes bollard pull = small tug
  2. 17 to 24 tonnes bollard pull = medium tug
  3. 25 to 45 tonnes bollard pull = big tug
  4. Above 45 tonnes bollard pull = x-big tug

Unless otherwise stated, the number of tugs assigned in these guidelines are for vessels operating under their own power.
