Our team has worked completed more than 150 highly successful custody transfer projects both domestically and around the world. This has led to a unique ability to develop systems suitable for harsh climates and different operational requirements. We can help at every step of the design process, from developing site plot plans to selecting the most appropriate equipment for the task to detailed design engineering. If you are planning a HAZOP or LOPA for a truck, rail, or marine loading system we would be happy to participate.

We specialize in providing multi-discipline commissioning personnel with a high degree of expertise in process safety. Our commissioning process not only covers standard commissioning items such as control system logic testing, instrument loop checks and calibration and testing (meter proving) but also provides you with the highest level of assurance that your system is ready for custody transfer. This includes a full system audit that can be provided to customers. In addition, we train all of our employees to the highest standards of safe work practices.
