Loading and Discharging

While a vessel is alongside the main engines must be maintained in a state of readiness at all times for vacating the Terminal at short notice. Vessels undertaking approved repair work as detailed in Regulation 19 of ‘Jetty Safety Regulations’, may be allowed to immobilise under controlled conditions.

Load Line Regulations

For tankers departing between 16 October and 31 October and 1 April and 15 April inclusive the MCA has confirmed that vessels can load to summer marks providing they precede southerly after rounding Ramna Stacks or Muckle Flugga. If they proceed on a northerly course to the USA or Canada above 60º north after departing then North Atlantic Winter Season Zone 1 applies, i.e. winter marks.

Jetty Facilities

There are four jetties located in deep water on the northern shores of Sullom Voe. The jetties are numbered one to four in sequences from East to West:

• Number one jetty has facilities for both crude and LPG the vessel sizes below.
• Number two jetty has crude oil loading facilities only in the size range set out below.
• Number three jetty is used solely for the import and export of crude oil from the Schiehallion oilfield west of Shetland.
• Number four jetty is currently not in service, but can be used for lay-by for certain vessels.

Larger tankers may be accepted at the discretion of the Harbour Master and Terminal Operator.

Capacity of Jetties at Sullom Voe

Liquefied Petroleum Gas (LPG) Ships

There is a single LPG insulated pipeline from the LPG storage area to Jetty one for tanker loading. The LPG tankers range in size from 10,000 to 75,000 cubic metres capacity and they transport butane and propane under refrigerated conditions as in the onshore tankage.

All jetty LPG drains and ships’ scuppers whereby LPG can, in case of spillage, escape to the Harbour shall be open before loading or discharging commences and shall be kept open throughout the procedure.

All vessels calling at Sullom Voe Terminal must be in possession of a certificate of fitness under the terms of the IMO code for the construction and equipment of ships carrying liquefied gasses in bulk, and be in possession of an appropriate Classification Society’s Certificate.

Loading Systems

All crude loading arms are 150 ASA 16 inch hydraulic connections. This includes number one jetty where 16 inch connections are attached to 12 inch arms. All LPG loading arms have 300 or 150 ASA camlock connections.

Loading Arm Size

Connection of Loading Arms

Vessels should arrive with the required spool pieces fitted to their manifold for either crude or LPG lifting. Manifolds should comply with the latest OCIMF Standards. As a minimum there must be 500mm between faces of reducer/spool presented for connection. Reducers must be equally tapered.

Failure to present correct reducer/spool will result in delays. The Terminal does not have reducers but does have 16” to 16” spool pieces. Should it be necessary to use the Terminal’s spools a charge will be levied.

Manifold Heights Above Chart Datum

Note: Maximum allowable pressure on lines and connections is 150 pounds per square inch.
