Das Zirku & Mubarraz Ports are located off the coast of the Emirate of Abu Dhabi. It consists of DAS Island terminals, Zirku Island terminal and Mubarraz Island terminal. The port contains a number of marine terminals for exporting crude oil, LNG, LPG and Paraffinic Naphtha. The port provides facilities for cargo handling, storage and distribution. The port area also accommodates an extensive industrial complex.
DAS Island lies 90 miles North West of the city of Abu Dhabi, capital of the United Arab Emirates. DAS Island is the terminal for processing, storage and export of crude oil from the Zakum, Umm Shaif, Bunduq and ABK oil fields by ADNOC Offshore; and for liquefying the associated gas and sulphur, processed by ADNOC LNG.
Mubarraz Island includes the export terminal for crude oil produced by Abu Dhabi Oil Company Limited (Japan) (hereinafter referred to as “the Company”). Crude oil produced from the Company’s Mubarraz Oilfield is transport to Central Facilities Platform (CFP) situated approximately 19 miles east northeast of Mubarraz Island by 4” to 14” flow lines, thence relayed by 14” transmission line to the island. Other crude oil produced from the West Mubarraz oil field is transported through an 8” pipeline under the causeway to a storage tank. Both crude oils are blended and exported from the Island as Mubarraz Blend crude oil. The company has tank storage capacity of 2,240,000 barrels of crude oil on the Island. Average API Gravity of crude oil to be loaded is 39 degrees and flash point is below 0º Centigrade.
The port is well equipped for handling hydrocarbon cargoes.
The port is open all year around and only rarely closed due to severe sand storms, wind or fog.
The port is constantly improving. Major developments are described at the PPA website:

PPA recognizes the provisions of the International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWM convention) as adopted by IMO on 13th February 2004 and gives full effect to ROPME requirements for Ballast Water Management for the ROPME Sea Area as issued by the IMO on 2nd February 2009, vide MEPC 59/INF.3
This convention recognizes two standards:
Regulation D-1 Ballast Water Exchange Standard and
Regulation D-2 Ballast Water Performance Standard. Eventually most ships will need to install an on-board ballast water treatment system.
PPA is currently working towards issuing a new set of regulations governing the management of ballast water until such time as the BWM convention enters into force, the requirements set out below shall apply.
This section shall apply to all vessels calling at any Petroleum Ports/Terminals for any purpose; of GRT 400 tons and above, with sea water ballast on board originated from outside the ROPME sea area (RSA).
Note: Vessels below GRT 400 tons, with sea water ballast on board originating from outside the ROPME sea area (RSA) shall endeavour to exchange ballast water prior to entering into UAE waters as far as practically possible.
The following vessels are exempted from the requirements of this section:
Other than for vessels arriving from zones affected by cholera or outbreak of similar contagious epidemics/pandemics, the Authority may grant exceptions to vessels from the requirements of this section in the following circumstances:
Except in emergency cases, PPA does not currently offer a reception facility for discharge of sea water ballast or sediments.
Vessels that arrive at any of the Petroleum Ports and found to be in violation of the above requirements, may be denied entry into the port, be prohibited from discharging her ballast or become subject to the appropriate proceedings and sanctions under the laws of the UAE, including, applied fines or detention and shall be reported to its flag administration.
Except for undue delay or detention, which will be avoided as far as practically possible, no compensation will be considered for delays incurred as a result of extended investigation of ballast water contents on board, or for a vessel being not in compliance with the above requirements.
The Authority may under special circumstances, e.g. increased risk of introduction of alien species, impose more stringent requirements than those laid down within this section.
Vessels intending to call at Das Zirku & Mubarraz Ports should have the following publications on board in either Paper or approved Electronic format:

Name - Mubarraz Island Terminal - ADOC (Crude Only)
Tanker loading is accomplished by means of a Single Point Mooring (SPM) system installed about 8 nm offshore east of the Island. The berth is a single point mooring system consisting of a buoy 50.83 feet (15.25 meters) in diameter, moored to six pendant legs of 3” high strength chain shackled to anchor piles at a radius of 1100 feet (330 meters), and having a rotating deck carrying the pipeline and mooring connections.
Lat. 24º 26’ 05. 1” N, Long. 053º 31’ 35. 9” E
16.5 meters (55 feet)
The SPM is suitable for tankers up to 330,000 MT SDWT, the maximum trim for manoeuvring is 3 (Three) meters by the stern
Attached to the mooring connections on the berth are two 18” Nylon double braided ropes (144 mm dia. calculated breaking strength 440 Tons). These ropes are 60 meters long, and have at their free end a length of stud link chain, which includes an enlarged end link for fixing to the chain stopper on the deck of the tanker. From the outer end of this chain, there are two mooring lines consisting of pick-up ropes and a towing rope (port side only). The nylon rope is supported by lace floats and the chain is hung by polyurethane buoy 1.5 m in diameter.
Once picked up on the forecastle, the two mooring chains are made fast to the vessel’s chain stoppers. The size of the Panama hole should be at least 300 mm diameter applied with OCIMF standard.
One 32” crude oil line has been laid approximately 52,500 feet (16 km) from the shore to a position close under the buoy. From the underwater manifold, the crude oil goes to the buoy through a 20” underwater hose. The connection between the turret piping of the SPM and the tanker manifold consists of one hose string composed of 24” & 20” x 875’ floating hoses and two hose strings composed of 16” x 180’ tail and tanker rail hoses.
The maximum loading rate of crude oil is 34,000 bbls/hr or 5,400 kl/hr. Normal loading rate is (5,400 kl/hr).
The Pilot & Loading Masters provided by the Marine Service Provider will undertake pilotage, mooring and unmooring of the Vessel. The Loading Master are also authorized to control all the loading operations.
The Pilot & Loading Master will advise the Master of vessel on approaches to the SPM, Mooring, unmooring, connecting and disconnecting cargo hoses and all other operations within the Port area. All manoeuvring of vessels within the Port area shall be done only in accordance with the advice of Pilot & Loading Master, subject to the understanding that in all cases and circumstances the Master of the vessel shall remain solely responsible for the safety and proper manoeuvring of the vessel.
When the vessel is ready in all respects for loading, the vessel’s Officer must inform the Loading Master who will transmit the necessary messages to the Mubarraz Terminal on the Island.
All Vessels arriving at this port are required to have on board sufficient segregated ballast to give a safe draft for manoeuvring purposes. Vessels arriving with insufficient ballast may be required to increase the quantity, should the Pilot consider that it would not be safe to berth the vessel for loading. As a general rule, Vessels shall not start discharging ballast until mooring is completed.
Vessels must submit the following documents:
All cargo documents and shore figures are usually prepared at Mubarraz Island Terminal office. Early Departure Procedure (EDP) is normally used at the Mubarraz Island Terminal. The Master is required to sign the cargo documents provided by PPA / Port Master as the Company’s representative and on behalf of the Vessel’s agent.
To mean all waters encompassed by a line joining the following positions and shall include all jetties, wharves, structures, sea berths (SPM), ZIRKU Island and the part of the Separation Zone situated within the Port limits.

The cool winter season extends over November to February with mean daily maximum temperatures of 25 to 30° C and night temperatures of 10 to 15° C. The lowest recorded temperature being 4° C. Ground frost can occur inland. The hot summer season extends over May to September with maximum day temperatures between 40 to 45°C, the highest recorded being 48° C, Night temperatures are about 20 to 25° C, Therefore, it is important that during the hot season the temperature within the visiting tankers accommodation shall not exceed 25° C whilst moored at the SPMs.
Relative humidity is high throughout the year averaging between 50 to 60 per cent by day and 75 to 80 per cent by night. Heavy dew may be experienced throughout the year. Rainfall is usually associated with thunderstorms which are prevalent from November to May giving a total annual rainfall of 10 to 50 mm. Rain is rare during the remaining months while in some years there is none at all.
Throughout the year the prevailing winds are from the West to North North East sector. They are strongest between November and April when they occasionally reach gale force. Gusts of up to 50 knots have been recorded (April) and a 24-hour mean wind speed of 32 knots from the North-West is on record (January). The shamal or strong North West wind may blow for periods of up to three days and raise a rough sea with waves up to 4.5 meters. Land and sea breeze is experienced throughout the year.
Visibility is 10 nautical miles for 70 per cent of the time and less than 2 nautical miles up to 5 per cent on occasions due to dust, haze or radiation fog. Fog can occur during any month of the year but is most frequent in winter; normally it develops during the night and early morning and clears by 10.00 hours.
Sea temperatures at 3 meters depth range from 20 ° C (in winter) to 32° C (in summer). During the summer the 15 meters depth temperature is only a degree or so lower than that at the surface.
Prevailing winds are from the North West. However there are occasions, when sudden gusts of local ‘Shamal’ winds may be experienced where winds can go as high as 50 kts. or higher. Rise of tide can be up to 2 meters but the usual variation is 1 meter. The highest average, spring high tide is about 2.0 meters above chart datum. The lowest average, neap high tide is 1.0 meter above chart datum.
Prevailing winds are from the North West. Rise of tide can be up to 2 meters but the usual variation is 1 meter. The highest average, spring high tide is about 1.4 meters above chart datum. The lowest average, neap high tide is 1.0 meter above chart datum.
The maximum tidal level in this area is 7 feet; the average tidal level at the Spring tide 3 feet and the Chart Datum is 0.8 feet below I.S.L.W. Tidal current is variable according to the lay of the land. But the flowing tide usually runs South-eastwards and ebbing tide North-westwards. Speed of the current is around 2 knots at the highest. “Tide and Current Table” is published annually by the Company applicable to Mubarraz Island and the surrounding area and may be obtained on application to the company.
At Zirku Island tidal currents are semi diurnal. Roughly the flood runs from west to east and the ebb runs from east to west.
Eddies are created at the vicinity of any obstacle (breakwater, jetties, etc.) especially close to the south sandy island. Currents can reach a speed of 2 knots. These predictions may be found to be considerably altered by strong winds, especially the Shamal.
