Proposed Design & Build for Liquid Bulk Terminal (LBT5) at Westport, Pulau Indah, Port Klang.

LBT5 is the first independent refrigerated LPG terminal in Malaysia, jointly developed by Global Petro Storage (GPS Group) and Equinor to handle and distribute LPG products to domestic and international consumer market. Antara Koh submitted the winning design proposal for the jetty structure and was awarded the design & build project by port owner Westports Malaysia Sdn Bhd.

The terminal facility has a capacity to turn over 1.5 million tons of LPG each year, with a combined storage of 134,000m³ of refrigerated LPG. The new jetty was designed to handle the berthing of Very Large Gas Carriers (VLGC) and Q-max LNG carriers. In addition, a secondary trestle was constructed to connect the new jetty to an existing jetty which was upgraded to facilitate the berthing of a 5,000DWT LPG carrier.

On the whole, the terminal consists of a 380m length Main Approach Trestle with a Fire Pump Platform, a 385m length Secondary Trestle, a 1200m² Loading Platform, 2 Breasting Dolphins and 6 Mooring Dolphins. The dolphins are connected to one another by steel walkways.

The jetty foundation employed a combination of concrete spun piles and steel tubular piles with lengths from 50m to 60m. These piles were driven in one single length by our 60m and 80m height fixed tower piling barges equipped with Hydropro GPS system that enables accurate pile positioning on waters. The steel piles were protected against corrosion with marine grade coating and cathodic protection system. The superstructure of the jetty was mainly comprised of precast shell members or precast planks with reinforced concrete finishing. These precast members were creatively designed with an interlocking system that minimizes the temporary support required. They weighed between 5 - 40tons and were installed by our 150ton and 250ton crane barges.

Upon completion of the civil works, we installed the fender systems, QRH mooring hooks and navigational aids that furnished the jetty. We also assisted GPS Group to transport and install the pipe rack structures, pipe spools, fire-fighting equipment, local control station, Marine Loading Arms, Gangway Tower and Fire Monitors.

The engineering design was carried out based on the latest version of Eurocodes for maritime structures, and international ship and port facility standards. Antara Koh was involved in the process of local authorities’ submission from the beginning stage of Building Plan (BP) Approval to the final stage of obtaining the Certificate of Completion and Compliance (CCC).
