Port of Ras Laffan LNG berths

Ras Laffan Port was constructed in the early 1990s and is now one of the world's largest LNG exporting ports.

The port was designed as an export facility for Liquefied Natural Gas (LNG), condensate and sulphur derived from the processing of gas landed from the North Field Gas Reservoir situated 67 km NNE of the Port.

Ras Laffan is planned to expand rapidly over the next few years and have identified the need for new multi-user liquid product berths from which
Gas-to-Liquids (GTL) products can be exported from amongst many products.

Designed for two vessels

The berths are designed to enable simultaneous berthing, mooring and loading of two vessels from 20,000 to 300,000 DWT.

The berths have a common approach jetty with approach road and have pipe racks on either side leading from the Lee Breakwater to the loading platform area.

The loading platform will accommodate eleven loading arms for each berth.

Constructon

The berths are constructed using mass concrete blocks and similar to the existing 2A and 2B Liquid Product Berths.

They consist of breasting and mooring dolphins, quick release hooks, catwalks for access to the mooring dolphins, navigation lights, fenders, fire fighting facilities, ship-to-shore gangway and lighting among other topside facilities.

The buildings consist of a common control building, an electrical sub-station and firewater pump house as well as pipe racks and other piping structures.

Design worksCOWI's design works included the following:

  • Investigation of the existing site conditions
  • Mooring analysis and development of a mooring layout in accordance with OCIMF guidelines considering the range of ships to be berthed. Base on this study the location, number and type of mooring equipment was determined.
  • Detailed design of mass concrete block wall and capping, mooring dolphins, earth and granular fill and scour protection.
  • Design of the tie-in to the existing Lee Breakwater including connection to existing pipe racks.
  • Design of new concrete pipe racks including loops and anchors along the access to the berth and steel pipe bridges at substation, control building and loading platform.
  • Design of loading structure, relieving platform, metering area structure and meter proving structure.
  • Design of civil infrastructure including access road, crash barriers and duct crossings, drainage, lighting foundations and signage.
  • Design of buildings, consisting of control building, substation and firewater pump house. All buildings were designed to be blast resistant.
