  6. Determination: Anemometer (in Knots) holding at the specific wind speed or above for Not less than 5 minutes.
  7. If the vessel is already underway and the visibility drops, further action of continuing the passage or proceeding to anchorage shall be based on the discussion between the pilot and the master of the vessel.
  8. Pilot transfer operations shall be suspended if pilot boarding is difficult due to high swell or any other adverse weather condition.

    2. Minimum Under Keel Clearance
    3. Squat
    4. Vessel load condition and response
    5. Visibility, Weather and current
  5. Under tugs assistance, speed of the vessel shall not exceed 4 knots at any given time.
  6. Whilst passing and within the confines of the breakwaters, speed of any vessel shall not exceed 5 knots.

  8. Vessel’s owned/operated by the Authority or by the Port operator are exempted from the above restrictions.

 

8.2.2 - Mubarraz Approach - Limitation of Speed

Near the Pipeline

Speed should be limited to a maximum of 8 knots for one mile proceeding and for one mile beyond the buoy (1) as 42” submarine pipeline lies 1.5 meter above seabed on ZADCO and crossing tanker the channel buoy (2) as submarine pipeline between CFP and Mubarraz Island.

Pipe Line Position

i. Near the buoy No.1, in position approx. Lat.24-49.44N, Long.053-17.29E

ii. Near the buoy No.10, in position approx. Lat.24-29.95N, Long.053-40.40E

Other Area

After the Pilot/Loading Master boarded, the vessel is able to proceed with Sea speed as far as buoy No.7 and then shall reduce to at Harbour speed in accordance with Pilot’s instruction.

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
