Our Strong

Our extensive track record and rich experience in process improvement projects, feasibility studies, energy auditing for improvement opportunities and the implementation of online energy management/performance monitoring systems puts us in a unique position to working credibly with your process engineering and operational teams to drive for better plant performance and increased profitability.

When they are well designed and properly implemented, improvement retrofits can deliver step changes in plant performance. However, we also believe that a lot can be done to achieve better performance just by good operations and proper maintenance. We help plants to harvest such low hanging fruits by first identifying them and thereafter to continuously track them with online monitoring systems. It is our firm view that such information systems are key to achieving a performance-oriented culture in the organization.


Started up in 2001, we are a Singapore based company comprising of experienced engineers with process, maintenance and operating experience in the refining, gas processing, petrochemical and power generation industries. Check out our Senior Team.


MECIP Global Engineers Malaysia (Oil & Gas Project Engineering).

PT MTS Indonesia (Maintenance Technology Services).

Dilogue Services Saudi Arabia (Specialist Maintenance Services).

Equinox Software and Services Pvt. Ltd.

CSE Global Ltd Singapore (Systems Integration).

CRTsoft Company Ltd Beijing (Asset Performance Monitoring Software).


Since 2005, we are a Nationally Accredited Energy Service Company for the Power, Refining and Petrochemical Industries under Singapore National Environmental Agency – Energy Sustainability Unit.

With effect from February 2019, we also have EEOA Energy Efficiency Opportunity Assessors certified by the Singapore National Environmental Agency and Institute of Engineers Singapore.



Our Online Performance Monitoring software ACTSYS@ONE™ encapsulates our domain expertise, energy auditing methodologies and years of experience (since 2005) of implementing online performance monitoring software and how to get it right. Find out more.

Tackling the energy and emission challenges of Process Industries requires strong domain knowledge and a sound understanding of thermodynamic concepts. We have deep domain knowledge of Refineries, Petrochemical Plants and Power Plants which we combine with the use of process and thermodynamic simulation software modelling to work on a wide range of plants helping them to improve their efficiency and profitability.

These enable us to carry out accurate analysis of performance gaps through rigorous modelling of equipment and processes. We also make use of data visualization tools to spot systemic problems especially for systems which cannot be rigorously modelled.

Energy Audit
Energy Audit

Energy Audit is an evaluation of the energy performance of a process, plant or a facility through analysis of the energy flows with an objective to reduce the overall energy consumption of the plant.
