Marine engineering refers to specialized water-related engineering tasks and planning, which constitutes HSL’s core strength. In its early years, HSL started as a sand dredging and landfill operation with a single ship which the company was named after – the Hock Seng Lee, or “good business” in the local Hokkien dialect. Since then, HSL has progressed to become a leader in this niche field.
It now undertakes mass land reclamation for industrial estates, townships and other infrastructure projects. Sarawak’s swampy terrain means reclamation is an essential precursor to most construction activity.
The Mark III, HSL’s fully computerised hydraulic cutter suction dredger in action.
HSL has extensive experience in dredging as well as a comprehensive marine engineering equipment ﬂeet. It has invested in specialised suction dredgers, including a fully computerised hydraulic cutter suction dredger, the Mark III, pictured above. Obtained for RM28 million, the vessel has served the company for over three decades, and is still going strong.
The company remains the only contractor in Sarawak to own such equipment, giving it the advantage of faster, more efficient sand extraction, haulage and filling than its competitors. It also has a ﬂeet of tug boats and steel barges mounted with clam-shell bucket cranes to perform sand extraction. Water-related infrastructure projects which draw on HSL’s marine engineering skills are an area in which it excels.
These can range from mini-dams and weirs to ﬂood mitigation and sea wall protection. Rural water supply, water intake and processing facilities as well as centralised sewage systems are areas of ongoing growth for the Group.
The Group’s decades-long experience in the field contributes to its ongoing success in its projects across the board, including the Kuching centralised sewerage project and Pan-Borneo Highway project, the latter of which includes the construction of several bridges.
HSL continues to be active in projects that draw on its competitive edge in marine engineering, which includes a flow of infrastructure demands from the SCORE initiative and from power generation needs, along with undertaking weir and port construction, flood mitigation, sewerage/ tunnelling works and various water-reticulation and shore protection activities.
