PROJECT DESCRIPTION

December 2561 – May 2564

NSC Consortium (NSC and SPAN) involved in tender design and detailed design and construction engineering services of the marine structures which consist of approximately 5 km length of the approach jetty trestle with 24 m typical span length, and 5 m width of roadway.

The jetty trestle is supported by precast the prestressed concrete I-girder of 1.60 m depth. This trestle will be connecting the jetty head or Berth platform to the LNG receiving terminal located onshore. At jetty head, there will be 2 units of Berth structures which include and berthing facilities, such as unloading arm, gangway tower, mooring and breasting dolphins, etc. All these structures at Berth platform area will be controlled by Jetty control room, situated on a separate platform. In addition, there will be also the tie-in structures that will be connecting the LNG main pipes from Berth#2 to the on- shore terminal while construction of Phase II has not been commenced yet.

The project also included the design of Seawater intake and seawater outfall structure located both onshore and offshore. These structures will receive the seawater through the double concrete tunnels (3.20 m diameter, 1350 m length) constructed by pipe-jacking method, after the process in terminal plants, these seawater will be passing back to the sea via another double concrete tunnels (3.20 m diameter, 1150 m length) and steel diffuser pipe of about 400 m length. In addition, NSC also performed the design of reinforced concrete retaining wall of 7.75 m height, and 575 m total length.
