Twelve industries, because the physics travels

A fatigue crack does not care whether it is in a pump casing, a drilling bit or a cooling tower. Our sector list has widened as clients brought us problems that looked familiar in a new context — most recently in bioengineering.

01Sectors served

02Cross-industry

The failure modes that keep recurring

Whatever the sector, clients arrive with one of about eight questions.

Hydraulic shock

Pressure waves on pump trip, valve closure or loss of liquid column.

Fatigue and residual life

Cyclic loading and remaining service life across the full life cycle.

Seismic qualification

Response spectra and test methodology for critical plant.

Thermal shock

Transient gradients in thick walls and dissimilar materials.

Cavitation and erosion

Where the flow damages the equipment that carries it.

Noise and vibration

Machine-room acoustics, structure-borne paths, insulation.

Sealing under load

Joints that stay tight through pressure, thermal and seismic cases.

Extreme events

Blast pressure waves and aircraft impact on critical housings.

03In focus

Oil and gas, from the bit to the separator

Four linked models along one production chain — a representative example of how a multi-discipline programme is divided.

01

Drilling process

The drilling process itself simulated by FEA, so the tool loads come from the process rather than an assumed case.

02

Roller-cone and PDC bits

Stress analysis of bit bodies and cutting structures. The team holds patents on single-cone bit designs.

03

Fluid to the cutting zone

CFD of how drilling fluid is delivered to the bit.

04

Mixing and separation

Multiphase CFD of oil mixing and separation, through to the separation efficiency of a downhole gas separator.

Working in a sector that is not listed?

The methods usually transfer. Tell us the loading, the medium and the code you have to satisfy, and we will say plainly whether we are the right practice.
