HISC Assessment of Subsea Gate Valve

The assessment successfully identified the areas of the valve most susceptible to degradation and potential failure under service conditions, allowing design improvements to be implemented before manufacturing began. Critical regions requiring modification were highlighted early, enabling the client to address issues when changes were still cost-effective and straightforward to implement. PDL provided practical engineering recommendations to improve the design and reduce technical risk, while also identifying areas where additional verification would strengthen overall confidence in the product's long-term performance. By undertaking the assessment during the design phase, the client avoided costly rework, reduced programme risk and gained assurance that the valve would meet the demanding requirements of subsea operation. The project demonstrated the value of early-stage design assurance, helping the client optimise the design, improve reliability and progress towards production with confidence.
