Meet our ESI Team

Our ESI Industry experts bring decades of research and development experience to bear on clients' projects. With specialists in high pressure engineering, safety critical systems design, hydraulics, fluid mechanics and fluid sealing, we can address the needs of clients across the industry spectrum.

Mark Fairhurst, Technical Director

Mark’s professional career started 35 years ago in high pressure water and abrasive water jet cutting/cleaning with the development of a patented ASJ system.  His expertise was broadened to the fluid power industry working on the development of standards relating to oil hydraulic contamination, filtration and pressure impulse/fatigue.

He has designed, built and operated a varied array of HP/HT test rigs for water, superheated steam, oil, fuels, combustible gasses and LNG and is regularly consulted on a broad range of projects  such as troubleshooting in the aerospace and marine industries, safety critical system designs in the defence and offshore industries and  contamination sensitive systems in the food and beverage industry.

He is presently the Vice-Chairman the product testing committee of the BFPA/BSI, and the Chairman of the Technical Advisory committee of the Water Jet Technology Conference.

Emily Ho, Senior Consultant

Emily is an expert in thermodynamics, fluid mechanics, heat transfer, process engineering, fluid sealing and material science.  Her work involves compressible and incompressible fluids at high pressures and extreme temperatures.

She has over 20 years experience in leading process and equipment, research and development projects from concept, feasibility study, scale-up, plant design, installation to commissioning.  During her career, Emily has consulted on a wide spectrum of applications including fluid sealing for heavy duty diesel engines, hydraulic flood barriers and transmissions, gaskets for fuel cells, flow analyses for boiler tubes in nuclear power stations, supersonic steam injection and nozzle design for starch hydrolysis by enzymic reactions.

She is presently a member of the Fluid Sealing working group in the ISO Fluid Power Systems and Components Technical Committee.

Craig Knight, Senior Consultant

Craig has nine years experience of fluid engineering projects in Engineered Systems in defence and aerospace.  He has worked on the full spectrum of activities around product design, development and qualification of systems including: hydraulic energy converters, high pressure abrasive water jetting systems used for surface decontamination and firefighting, pressure fatigue testing of aerospace equipment and HP/HT flow testing with of single and multiphase incompressible and compressible fluids.

Craig is a chartered engineer with the IMechE.

Paul Fuller

Paul joined BHR Group in 1988 and is primarily focussed in projects involving high pressure engineering. Heavily involved with the innovative DIAJET® water-jet cutting system, he has commissioned, trained and utilised his mechanical engineering skills in such diverse projects as dismantling SS20 rocket motors, nuclear silo decommissioning and contract cold-cutting both on and off-shore.

Paul has recently project managed a broad range of critical system projects for clients in the Defence, Nuclear and Oil & Gas sectors and undertakes witnessed type approval testing of clients’ products.

He is a member of IMechE and is qualified under NEBOSH Health & Safety guidelines.
