Dumai (IDDUM)

Dumai Port, is a key hub for crude oil exports. In addition to its primary role in oil shipments, the port handles general cargo and has a significant trade in log exports, making it a vital gateway for regional trade and industry.

Tropical.

The port of Dumai is located on the S side of Rupat Strait, on the mainland coast of Sumatera.

Harbour: LOA 229.13m, beam 36m, draught 8.5m, 85,594DWT. Offshore: LOA 251.56m, draught 15m, 115,829DWT.

Approximately 6,800,000t of cargo, 5,300 vessels and 196,000 passengers are handled annually.

If a vessel is not met by a pilot launch on arrival or not instructed to berth on arrival it should proceed to the anchorage area. The general anchorage area for Dumai is N and W of the oil wharves. The minimum depth of water in this area is 13.7m. Holding ground in the anchorages is considered to be good, the bottom being clay. Cargo vessel anchorage in mid channel, NW of the cargo wharf. Tankers in ballast and deep draught loaded tankers in the N part of Selat Rupat, NW and N, respectively, of the alongside berths. Anchorage is prohibited N of the alongside berths. Two mooring buoys are laid 1nm WNW of Dumai. Mooring dolphins are provided to all jetties.

Approach to the port of Dumai: The port can be reached by deep draught vessels by proceeding from Malacca Strait into Bengkalis Strait and following a buoyed channel on a S'ly course for a distance of 22nm to the junction with the Rupat Strait. Vessels must then turn approx 180° to enter the Rupat Strait and then proceed W'ly for a distance of 33nm to Dumai. The Bengkalis and Rupat Straits fairways have been wire dragged clear to a depth of 24.0m and 18.3m respectively (LWS). Based on that survey, a draught limitation of 17.0m and a max LOA of 315m has been imposed.

Each of the four CPI wharves is equipped with a docking sonar for monitoring the approach speed and distance of approaching vessels. Terminal personnel relay the information to the pilot or Master onboard the vessel by portable radio.

Sea pilotage and harbour pilotage are compulsory. Berthing and unberthing throughout 24 hours. Sea Pilots: Pilot boards vessels in position 4nm E of the shore station. Vessels waiting for the pilot should anchor from 3-3.5nm E of the pilot station. Six hours prior to arrival at Dumai Harbour area, all vessels should contact Dumai through VHF Ch 16, 12, 14. Harbour Pilots: A government harbour pilot will board a vessel on arrival if a berth is available and will advise and assist in proceeding to the berth. Pilot boards in the Cargo (Berthing) Anchorage (01°42.5'N 101°26.0'E) or on arrival at Lightbuoy No 18 (01°40.0'N 101°37.8'E) if a berth is available.

The E limit of Dumai pilot area is the meridian of 101°30'E.

Bad weather is rare and fog is virtually non existent in this area. Visibility is normally good except during heavy rain-squalls.

Mean tidal range is approx 2.4m and 0.8m at springs and neaps respectively. High Water Spring: 3.6m, Low Water Spring: 0.4m. Tidal Streams: In the E part of Rupat Strait, the stream sets: ..... Direction Rate Duration E going 2kts 4-5hrs W going 3kts 7-8hrs There is no slack period during spring tides and only a brief period of slack during neaps; the stream reverses direction almost immediately.

Five diesel tugs available, 3,200hp. Tugs are normally stationed near the oil jetties.

Ballast: For safe manoeuvring it is compulsory for tankers to arrive with sufficient clean ballast water onboard to meet the requirement for minimum safe manoeuvring draught. All ballast water onboard tankers, other than domestic tankers, loading at Dumai must be pumped overboard after arrival at a berth and prior to loading. If after arriving alongside a vessel is found to have dirty ballast water onboard the vessel will be sent to sea to accomplish the necessary tank cleaning. Such action will be to the vessels account and Caltex PI will not accept responsibility for the resulting delay to the vessel or any claims of the result thereof. A new Notice of Readiness to load must therefore be tendered. "Load on Top" procedure is expected to be carried out by each vessel loading at Dumai. Minimum draughts: Minimum draughts recommended for various tonnage tankers are as follows: ..... DWT Tonnage Forward (m) Aft (m) 1. 12,000-22,000 3.66 6.10 2. 22,000-32,000 4.88 7.32 3. 32,000-45,000 5.49 7.92 4. 45,000-60,000 5.79 8.23 5. 60,000 and over 6.71 8.53 The above is recommendation only and the Master should use his own discretion in order to have safe manoeuvrable draught on arrival and while berthing. Responsibility: Vessel's personnel are at all times responsible for the safety of the vessel and must therefore make provision to exercise all necessary precautions. Constant Readiness: When alongside a berth, a vessel's engines and propulsion machinery must be maintained in a state of readiness to enable the vessel to leave the berth at short notice. Signals: Vessels bound for the oil terminals at Pelabuhan Dumai or Pelabuhan Sungaipakning must show the following from time of passing Gosong Raleigh (02° 07'N 101°53'E) until arrival at the terminal. .....
