8.3 - UKC

  1. Crossing Subsea Pipelines

    When crossing over any subsea pipelines, all vessels and crafts must ensure that, they maintain a minimum Dynamic under keel clearance of 3 meters. If under exceptional circumstances, vessels, crafts or rigs are required to cross such pipelines with an under keel clearance of less than 3 meters, a detailed procedure for such operation is to be submitted to the Harbour Master in advance and crossing may proceed only after written permission is obtained, in which case under no circumstances may dynamic under keel clearance be reduced to less than 1 meter.

  2. Navigating within port limits and in channels

    Vessels may enter or leave port at any time during the day or night subject to limitations on the minimum dynamic under keel clearance, i.e. taking into account the effect of extreme adverse weather conditions, ship’s sinkage due to effect of squat at the prevailing speed, bank effect, ship size & load condition, list and trim.
    To ensure safe channel passage, the following minimum dynamic under keel clearance shall be maintained for all ships entering or leaving the port:

    A Up to 100,000 SDWT 0.92 meters / 3 Feet
    B Up to 250,000 SDWT 1.22 meters / 4 Feet
    C Up to 350,000 SDWT 1.52 meters / 5 Feet
    D Over 350,000 SDWT 1.83 meters / 6 Feet


Unless otherwise directed by the Harbour Master:

  1. Passenger Vessels will have priority over and above all other vessels navigating within the Port Limits.
  2. Loaded vessel regardless of its direction of passage will have priority over partially loaded or vessel in ballast ( Port Regulation 4.2.4)


Overtaking in channels is not allowed unless it is extremely necessary and if the following conditions are met:

  1. Harbour Master express permission has been secured;
  2. Prevalent weather and visibility conditions are suitable;
  3. Maximum passing distance is maintained between the vessels;
  4. Both vessels are operating without any engine or steering gear deficiency; and
  5. There is a significant difference in speeds between the vessels to keep the interaction time whist passing to a minimum.


  1. Passing within channels is not allowed except under exceptional circumstances with prior approval from the Harbour Master.
  2. Passing of vessels within the port limits shall be subject to, vessels passing each other at a safe speed, sufficient to maintain steering, maximum safe distance off, appropriate to their size and the prevailing conditions of weather, currents and visibility.
  3. Pilots shall ensure that vessels approaching or leaving any berth shall transit while keeping ample distance away from vessels at berth. They shall navigate at a safe speed to avoid any surging effect on moored vessels.


Vessels shall, at all times, comply with the International Code of Signals and display flags, shapes and lights as required by the International Regulations for Preventing Collision at Sea.
