Our Approach and Scope of Services

Our approach to plant engineering services is grounded in advanced engineering practices and detailed analysis, moving beyond the limitations of conventional rule-of-thumb methods. While these traditional methods provide a basic starting point for design, they often result in overdesign or underdesign, leading to unnecessary fabrication costs and operational inefficiencies. Our chemical plant designers and simulation consultants adopt a systematic approach involving a thorough examination of key process variables to ensure optimal plant performance and cost-efficiency. Through comprehensive analysis, we assess the impact of these variables on plant outcomes and provide precise recommendations to minimise or prevent potential financial losses. This proactive strategy is central to our process, allowing us to identify and resolve issues before chemical plant construction begins. Our engineering services are further strengthened by robust in-house simulation capabilities, ensuring each design is meticulously optimised for both performance and cost. We are committed to delivering accurate and effective engineering solutions tailored to meet the unique requirements of our clients.

Director's Message

Performing engineering design, calculations or modelling & simulations without proper knowledge may lead to misleading results that can eventually cause costly catastrophic consequences. In my engineering & simulation consulting firm, only qualified personnel are assigned to projects in their respective area of practice. In general, all my engineering professionals or simulation specialists at principal level have at least 15 years of relevant experience. In addition, to ensure the simulation results are accurate, we will only assign personnel with a PhD qualification specialised in modelling and simulation. These simulation specialists are supported by engineering professionals to ensure their recommended solutions to the clients are practical, implementable and cost effective. 

To consistently deliver high quality deliverables, all projects are subjected to my firm's stringent quality control system. Every stage is thoroughly checked and reviewed to ensure the inputs or results are accurate and make engineering-sense before being allowed to proceed to the next stage. This strategy prevents small errors emanating from each stage to snowball into a large error which ultimately affects the accuracy of the final results, designs or systems. Finally, by keeping the size of my firm small, this boutique-size model effectively enables my firm to respond faster, to provide a much more personalised and highly focused professional engineering services to many clients.
