Whilst developing a new design of connection system, a major subsea connector manufacturer had a requirement for pressure and torsion test equipment. The equipment needed to be designed and installed to achieve their new testing requirements. Their priority was to engage with a company who would work with their design engineers to develop the complete system.
The initial top-level requirements were:
- Hydraulic testing to 10,000PSI while subjecting the test piece to external mechanical tortional loading.
- Tight tolerances on the pressure ramp up and ramp down rates.
- Operators were to be separated and protected from the high-pressure test area while testing was being carried out.
Initially, we organised an onsite meeting with Hydratron design engineers and the clients design team to fully understand the testing parameters and survey the location for the proposed test area.
Initial challenges were identified as follows:
Parts could be up to approx. 3m long with diameters up to approx. 2m and could weigh up to approx. 3000kg.
A large range of testing parameters needed to be incorporated into the control system. This was to cover the full range of products and give full flexibility to operators. They needed to either fully manually run various testing or allow the operator to set pre-programmed test parameters with various steps that could then be run fully automatically.
The operator needed to be able to detect and quantify an internal gas leak on the test piece during gas testing separately to the primary test pressure supply system.
Both options were considered and our client agreed to install a concrete sump, this proved to be the most suitable from both a safety and cost perspective.
