Our unique ability to incorporate specialist application tooling into pressure vessels is what sets us apart from all other pressure vessel manufacturers.

By creating a realistic testing platform, it enables the simulation of in-service operating environments and provides industry standard testing conditions. The integration of tools to manipulate the components whilst under pressure can also replicate the actual functionality of the Equipment or Device Under Test (EUT or DUT).

Most high-pressure testing is conducted to replicate real world applications; ranging from materials research to quality assurance. The vast majority of pressure vessel equipment, available on the current market, only provides a basic test platform for replicating standard environments.

We have pioneered many designs to meet the most demanding and stringent test standards. Using advanced innovative engineering, we can incorporate specific features to transform a simple pressure vessel, into a noteworthy test platform for use in extreme environments.

Realistic In-service Operating Environments:

  • Downhole Environment – H2S Sour Gas and Hostile Environments
  • Extreme Subsea Environments (Up To 5,000 MSW)
  • HPHT (Up To 2000 Bar At 325°C)
  • Ultra-Deepwater Exploration, Drilling and Extraction of Hydrocarbons (Up To 60,000 PSI)

Typical Industry Testing Standards:

  • API 16F – Marine Drilling Riser Equipment
  • API 17F (ISO13628-6) – Subsea Production Control Systems
  • API 6A (ISO 10423) PSL 1, 2, 3, 3G & PR2 – Specification for Wellhead and Christmas Tree Equipment
  • ASTM E647 – Fatigue Crack growth propagation (da/dN)
  • ASTM G129 – Slow Strain Rate Testing SSRT and Constant Extension Rate Tensile Testing CERT
  • ASTM G38, G49, G64, G139 – Stress-Corrosion Testing
  • EFC Publication No’s. 16 & No. 17 – Material and testing requirements for Carbon, Low Alloy Steels and Corrosion Resistant Alloys for H2S containing environments in Oil and Gas Production
  • NACE TM0177 – Resistance to Stress Corrosion Cracking in H2S Environments
  • NACE TM0198 – Slow Strain Rate Test Method for Screening Corrosion-Resistant Alloys (CRAs) for Stress Corrosion Cracking in Sour Oilfield Service
  • NACE TM0284 – Resistance to Hydrogen-Induced Cracking HIC

Types of Specialist Application Tooling:

  • Electrical and Hydraulic Connector – Wet Mate/ De-Mate, QCDC, Make and Break Connections
  • Electrical Penetrators and Feed-throughs
  • EUT and DUT manipulation devices
  • Instrumented Buoyancy Loss IBL Tooling
  • Mechanical Testing Devices – Tensile, Compression, Rotary and Axial
  • Media Agitators – Stirring, Mixing and Agitation
  • Temperature control Systems – Internal and External Heating and Cooling
  • Tilt Mechanisms – Multiple Test Orientation


Pressure vessels with integral high pressure agitation and mixing systems.

Mate/De-Mate Mechanisms

Automatic mate/ de-mate mechanisms incorporated into the design to meet strict testing requirements in line with API Standards.

Temperature Control Systems

Developed and engineered pressure vessels with Temperature Control Systems (TCS) cleverly incorporated into the design.

Vertical, horizontal or required position, dependant on specific requirements.

Mechanical Testing

Advanced mechanical testing devices incorporated into the design allow tests to be carried out at high temperature, high pressure and within aggressive media.

Pressure vessels with highly advanced mechanical testing devices incorporated into their design to measure certain properties such as elasticity, tensile strength, elongation, hardness, fracture toughness, impact resistance, stress rupture and fatigue; determining the suitability of a material or component for a given application

Actuation Systems

Actuation systems integrate neatly into the vessel design, to provide additional functionality; allowing the user to apply a load, create a mechanical advantage or operate a valve or mechanism within the vessel whilst at pressure and temperature.

IBL Testing Systems – Instrumented Buoyancy Loss

We develop and engineer pressure vessel systems specifically for carrying out instrumented Buoyancy Loss (IBL) testing of subsea syntactic foam buoyancy products in line with API 17L (ISO 13628-11)

Magnetic Agitators and Stirrers

We provide an advanced range of high pressure agitation and mixing systems; utilising a leak-free magnetic coupling to negate the use of rotary seals.

Media Separation

The integration of a pressure media separator into a pressure control system, ensures precise control is maintained, without subjecting the equipment to media that could cause damage or premature wear.
