A wholly owned subsidiary of UTOC Corporation in Japan
was established in Singapore since January 1989.

Our Journey started more than 30 years ago, UTOC Corporation of Japan set up its wholly owned subsidiary, UTOKU Engineering Pte Ltd in 1989. We had 12 staff in a rental office along Gul Road. Our name was officially changed in 1995 to UTOC Engineering Pte Ltd (UTOC). UTOC is under the arm of Plant Business Division, UTOC Corporation. The ultimate holding company is Mitsui O.S.K Lines Ltd, Japan.

UTOC initially focused on mechanical contracting for Singapore’s up and coming oil & gas industry. It later ventured into heavy lifting and equipment installation related works.

As the business grew rapidly, UTOC moved into a larger workshop in 2000. Then, with continued expansion, UTOC bought 13 Pioneer Sector 1 in 2006, and its second premises, at 352 Jalan Boon Lay, in 2008.

The second premise at 352 Jalan Boon Lay is also the place where we build our first dormitory called UNITY.

In 2019 UTOC further expanded the workshop and dormitory capacity.
