Toyo Engineering Corporation (President and CEO: Eiji Hosoi, "TOYO") has been awarded two expansion projects by Aster Chemicals and Energy Pte. Ltd. (Group CEO: Erwin Ciputra, "Aster") for its ethylene plant on Singapore's Bukom island. Aster is an integrated energy, chemicals, and infrastructure provider in Southeast Asia, strengthening energy resilience through rejuvenation and innovation investments.
The ethylene plant was originally constructed by TOYO. Having won the contracts to strengthen and expand its capacity reflects the high recognition of TOYO's expertise and deep experience.
Revamp Project 1: Ethylene Chiller Unit Revamp Project
TOYO has been awarded a contract by Aster for the rejuvenation of the ethylene chiller unit as part of Aster's plan to double its export capacity.
Last year, TOYO was awarded the Front-End Engineering Design (FEED) for this project, and following that, will now be responsible for detailed engineering, procurement service, and construction management (EPsCm*).
The export capacity expansion aims to double the ethylene export capacity of the existing plant and forms part of Aster's initiative to strengthen Singapore's role as an energy and petrochemical hub in Southeast Asia.
Revamp Project 2: Gas Turbine Unit Integration Project
In addition, TOYO has been awarded a contract by Aster Power Pte. Ltd., an affiliate of Aster, for the integration of a gas turbine unit at the same ethylene plant.
TOYO will be responsible for Front-End Engineering Design (FEED). This gas turbine integration project aims to enhance the overall energy efficiency of the existing plant by reutilizing the high-temperature exhaust gas as combustion air for the plant's existing heaters, thereby reducing fuel consumption. It is expected to make a significant contribution toward the realization of a decarbonized society.
TOYO has a proven track record of implementing this gas turbine integration technology both in Japan and overseas, and the contract award was achieved in recognition of its experience and expertise.
TOYO will leverage its extensive project experience in the petrochemical plant sector and its global management capabilities to contribute to the development of the rapidly growing Southeast Asian market.
* EPsCm: Engineering, Procurement service, Construction management
A service that provides detailed engineering and practical support during procurement and construction phases, including assistance in selecting equipment manufacturers and contractors, quality and delivery management of materials and equipment, and quality and schedule management of construction work.
