Our Business
Plant Engineering / Specialised Projects
From time to time, we secure specialized projects, which may not involve infrastructure for the transmission and storage of oil and gas. These projects require high engineering expertise where our engineering knowledge and construction experience are applied. Thus far, our involvement in such projects are in relation to specific engineering steps such as engineering design, installation, testing and commissioning.

• Lubricating Oil Blending Plants
In 1990s, when Lubricating Oil manufacturers moved into Singapore, WEC, with its versatile and experienced engineering workforce, had successfully won some 70% of the market to construct lubricating oil blending plants. These were turnkey projects, involving submissions of all authority approvals, engineering designs, procurements, construction and commissioning of the complete plants.

• Petro-Chemical and Pharmaceutical Plants
From time to time, we were involved in the construction of civil works and installation of underground pipelines and above ground piping works with associated instruments and controls for petro-chemical complexes in Singapore. These projects were generally managed by multi-national project management companies like Bechtel International, Foster Wheeler, Stone and Webster Asia Inc and WorleyParsons.

In 1994 WEC was awarded the engineering designs, and construction of a plastic compounding plant for GE Plastics China Ltd (part of the General Electric group of USA) in Nansha, Guangdong Province, PRC.

• Offshore Engineering & Installation Works
In 2004, we successfully completed the installation of a multi-deck offshore facility platform for oil production owned by CNOOC SES Ltd for an aggregate contract value of US$5.2 million. This marked our successful foray into the offshore oil and gas industry. For this project, we provided our customer with project management services and experienced in-house engineers and supervisors to oversee the installation works.
