What WEC Engineers & Constructors Pte Ltd does

WEC Engineers & Constructors Pte Ltd is a Singapore-headquartered EPCC service provider founded in 1972, specializing in aviation fuel system engineering, plant engineering for oil & gas and petrochemical facilities, and infrastructure projects. The company delivers turnkey solutions from conceptual design and FEED through engineering, procurement, construction, and commissioning, with specialized capabilities in fuel hydrant systems, emergency shut-off systems, SCADA, cathodic protection, and skid-mounted systems. It maintains offices in Singapore, Vietnam, Indonesia, Japan, and Sri Lanka, and serves a blue-chip enterprise client base including Changi Airport Group, ExxonMobil, Merck Sharp & Dohme, Lubrizol, Singapore Petroleum Company, and Public Utilities Board Singapore.

WEC's revenue model is project-based, with lump-sum or cost-plus EPCC contracts, supplemented by consultancy services and custom skid manufacturing. The company has progressively expanded its technology portfolio through strategic partnerships: with Biazzi (Switzerland) for hydrogenation and gas-to-liquid reaction processes, with Sakowin for methane plasmalysis hydrogen production, and with HeatVentors for thermal battery technology. Sustainability offerings (Green Compass trademark registered in 2023) and hydrogen production solutions represent a deliberate addition to the traditional aviation fuel and oil & gas core. Founder-led since 1972 by Managing Director Lee Chak Meng, the company employs 58 people and operates without disclosed institutional investors or public listing.
