bintulu samalaju submarine pipeline

SYS was tasked with the procurement, construction, and testing of a marine outfall pipeline for the Tokuyama Malaysia polycrystalline silicon manufacturing plant, located in Samalaju Industrial Park, Bintulu, Sarawak. Chiyoda Malaysia Sdn Bhd, the EPC contractor, engaged SYS for the supply and installation of the wastewater marine outfall pipeline, with engineering oversight provided by Jurutera Jasa (Sarawak) Sdn Bhd.

The project involved the installation of a 1,000-meter onshore and 800-meter offshore HDPE pipeline system. The offshore section ended in diffuser outlets situated at a seabed depth of -3.8 meters, with the entire pipeline being secured with concrete sinkers. The scope included supplying 1,800 meters of 630mm OD PE80 PN12.5 HDPE pipes, and rock trenching up to a maximum depth of 4 meters. Additionally, a navigation light tower was constructed to mark the marine outfall.
