Loading and Discharging

Jetty Fire Fighting Facilities

The oil loading jetties are each equipped with two independent fire fighting systems, one for water alone and the second for either water or foam. Hydrants are spaced along the jetty access road and jetty head.

Monitors are installed to provide a water curtain in the area of the jetty head and between the access tower and manifold area. Elevated monitors are also positioned at the top of the access and monitor towers. A sprinkler system protects the access tower.

The hose couplings are 2.5” standard instantaneous female type and the fire main in the access tower can accept international connections.

Fire Precautions

Every vessel's fire fighting appliances including main and emergency fire pumps, must be kept ready for immediate use with at least one fire pump maintaining pressure on the deck fire main.

Before deballasting and loading/discharging operations commence, and during periods when permitted repair work is being carried out, at least two fire hoses must be uncoiled and connected to the fire main. One of the fire hoses must be sited forwards and the other abaft the manifold.

The vessel should ensure that an International Shore Connection is available on the vessel’s fire main in the vicinity of the gangway.

Cargo Measurement

Meters are installed for cargo measurement. Bill of Lading quantities are calculated from meter readings.

Dirty Ballast Reception Facilities

The discharge of any dirty ballast into the waters of Sullom Voe is prohibited. All dirty ballast or non-segregated ballast will be discharged ashore for treatment. Non-segregated ballast includes ballast contained in any tank designed for or capable of being used for the carriage of crude oil. Tanks having a permanent connection to the cargo piping system are not considered to be segregated ballast tanks. Additionally, any ballast from segregated ballast tanks with high levels of mineral or chemical pollutant will be deemed ‘dirty’.

The Terminal can accept dirty ballast whilst providing the vessel with cargo.

The Terminal is unable to accept tank washings or slops from a cargo with API of less than 17.5.

Discharge of Clean Ballast Water

The discharge of ballast water from segregated or permanent ballast tanks into the waters of the Harbour will be permitted provided that:

For Further UK Guidance see MGN 363 (M+F) The Control and Management of Ships' Ballast Water and Sediments and MGN 81 (M+F) Guidelines for the Control and Management of Ships’ Ballast Water to Minimize the Transfer of Harmful Aquatic Organisms and Pathogens at http://www.dft.gov.uk/mca/mcga07-home/shipsandcargoes/mcga-shipsregsandguidance.htm


The Port Safety Officers of the Harbour Authority will, on occasions, board vessels carrying segregated ballast to obtain samples. The Harbour Authority may, as a result of information so obtained, refuse permission for the discharge of segregated ballast water taken on board in certain locations.

Permission for the discharge of ballast water must be obtained from the jetty staff.

Inert Gas

A random check of the quality of the inert gas in several of the vessels tanks will be made on arrival alongside to ensure the vessel complies with the statutory requirements regarding inert gas. If any of the tanks are found to have an oxygen content in excess of 8% the vessel will be required to vacate the berth and return to sea to complete inerting.

Purging of tanks whilst alongside is not permitted. Vessels must arrive at the berth with positive inert gas pressure.

Hydrogen Sulphide

Tests will also be taken to ensure a hydrogen sulphide content of less than 5 ppm. If higher levels are found the vessel will be returned to sea to purge.

Crude Oil Storage

Crude oil is stored in sixteen conventional floating roof storage tanks each with a capacity of 600,000 barrels.

Bunkering Facilities

There are no bunkering facilities available for tankers calling at the Port of Sullom Voe, other than for the Schiehallion shuttle tanker service.

Fresh Water

Potable water can be supplied to tankers at Sullom Voe. A charge is levied for the use of the facility. Vessels requiring fresh water should inform their Agents prior to arrival.

Dry Cargo Facilities

Construction Jetty

A concrete pier suitable for coastal traffic is located in Garths Voe, east of No.1 tanker jetty. The pier is orientated on a 108/288 degree axis, is 100 metres long and can accept ships on both north and south faces.

The north berth is equipped with a fixed ro/ro ramp, which has a width of 14.0 metres, a total length of 23.7 metres, and a fixed gradient of 1 in 22. The height of the sill is 1.67 metres above MHWS.

The pier is fendered with patent fenders and tyres. The depths at the pier range from 9.9 metres at the eastern extremity, decreasing to 5.0 metres at the ro/ro ramp.

Bunkers can be supplied to vessels using this jetty by road tanker.

There is no permanent dock force available on site but stevedoring services can be obtained via the local ship's agent or receivers of cargo, as appropriate.

Tug Jetty

Harbour tugs and pilot launches are stationed at an L-jetty located on the southern shore of Garths Voe adjacent to Sella Ness. The jetty is of cellular design and constructed of steel and concrete. Fendering arrangements consist of used tyres suspended at intervals along the jetty face. The minimum depth off the main face of the jetty is 6.9 metres. The jetty is suitable for coastal traffic but is not used as such on a regular basis.

Limited supplies of gas oil are available from a bunkering point on the jetty. Further supplies are available via road tanker.
