PART III | 8 Port Navigation


8.1.1 Permission

Navigation / movement within the Port limits are permitted subject to prior permission being granted by the Port Authority.

8.1.2 Nautical Publications

Vessels visiting the port area must have on board, a sufficient range of current navigational charts and other nautical publications (such as light list, tide tables, pilot books, etc.) relevant to the area either in paper format or SOLAS approved electronic form. These charts and publications must be of the latest edition and kept up to date with regard to notice to mariners and other notices promulgated for the area.

Environmental Operational Limiting Conditions for Cruise Vessel Manoeuvring
Manoeuvre Wind Direction Wind Speed [knots] Current Direction Current Speed [knot]


  • Above recommended environmental operational limiting conditions for vessel manoeuvring are applicable for both berths {(Berth 1 {NE Berth} & Berth 2 {SW Berth})} with vessels either Port or Starboard side alongside.
  • Environmental operational limiting conditions have been conservatively determined on the basis that these will occur at the same time.
  • Environmental operational limiting condition are applicable at the berth and turning circle.
  • Vessels are permitted to stay (dwell) at the berth for up to the 1 in 1 year return period condition defined for various incidences in the most probable sectors:
  • NW Sector: wind speed of 17m/s (or 33 knots) combined with a significant wave height Hs=0.9m with incidence of 45°N
  • NE to SE Sector: wind speed of 12.5 m/s (or 24 knots) combined with a significant wave height Hs =1.3m with incidence from 77.5°N

It is very important to understand that the limits stated above are for guidance purposes only and following contributory factors shall be taken into consideration before making any operational decision:

  • Sea State (swell, wave)
  • Tugs powers, movement and tug masters evaluation of the situation (Securing position) & evaluation of working conditions.
  • Vessel Condition (engine, steering, etc.)
  • Mooring boats

In all cases, evaluation of the situation to be conducted prior any decision reverting to the above parameters and subject to Pilot discretion.

Determination: Anemometer (in Knots) holding at the specific wind speed or above for not less than 5 minutes.

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.

Pilot transfer operations shall be suspended if pilot boarding is difficult due to high swell or any other adverse weather condition.

*** For Borouge terminal, depending on the business criticality, berthing may be allowed at wind speed of maximum 25 kts- NW’LY (gusting up to or steady at) under following conditions:

  • Only senior pilot to carry out the berthing operation.
  • The operations are recommended during daylight hours.
  • Berthing operation in 25 kts wind of a westerly or easterly direction to be avoided for the channel transit.
  • Formal Risk Assessment to be carried out before such conditional berthing operation.


  1. The maximum speed of any Craft/Vessel whilst navigating within the Jebel Dhanna Ruwais Port should not exceed safe speed but in no case shall exceed 15 knots.
  2. Vessels navigating within Channels (excluding the Channels highlighted below) shall not exceed speed of 12 knots:
    • Ruwais Approach and Borouge Channel – 7 knots each
    • ADNOC Gas Processing SHT II Channel shall not exceed 8 knots
  3. Vessels shall comply with the UKC policy as set out by PPA and as amended.
  4. In determining the maximum speed following shall be taken into consideration:
    • Maximum Draft
    • Minimum Under Keel Clearance
    • Squat
    • Vessel load condition and response
    • 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.
  7. Speed during embarking/disembarking of Pilots shall not exceed 4 knots.
  8. Vessel’s owned/operated by the Authority or by the Port operator are exempted from the above restrictions.

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 lunder-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

    1. Vessels using Dynamic Under keel Clearance (DUKC) service for arriving or departing Jebel Dhanna Ruwais Port
    2. a- Vessels using DUKC service offered by port authority approved service provider are not required to comply with the UKC requirements as per (ii)below.

      b- Vessel intending to use the DUKC service must submit the DUKC application form at least 72 hours in advance to the Harbour Master office, after confirmation from the Harbour Master office that a sailing window is available for the requested draft the Master of the vessel can request for usage of DUKC services directly from the approved service provider via their agents.

      c- By sending the application from to the HM office, vessel Master agrees to pay for the service irrespective of whether they use the service or not.

      d- Port authority will take all possible measures in ensuring high availability of the DUKC system. However, in case of any failure of the system or unavailability due to reasons beyond Port Authority’s controls, the Port authority shall not be held liable to any extent and the Vessel Master shall remain fully accountable and responsible in ensuring the safety of Life, Vessel, Cargo and the Environment.

      e- In case of usage of the services, the license fee must be agreed and settled between the Master and the service provider directly.

    3. Vessels not using DUKC service
      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.
  3. 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

    8.4 RIGHT OF WAY

    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. When two Vessels are ready to enter and leave the Port simultaneously, the outgoing Vessel shall have priority over the incoming Vessel provided that, by so doing, the safety of navigation or the International Regulations for the Prevention of Collision at Sea are complied with.


    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
