Connector Subsea Solutions
Project Background and Challenges:
As part of the platform decommissioning, the client needed to reroute their subsea pipeline by fitting a bypass spool to the existing bare pipe. This solution had to be both straightforward and robust, delivering a dependable mechanical seal for subsea pipeline integrity without the complexity of specialised welding or hot works.
Finding a reliable connector that could be installed quickly on a decommissioned pipeline—often in confined, remote locations—was critical to maintaining flow integrity and keeping the decommissioning schedule on track.
Technical Specifications
Under the original contract, CSS supplied:
- 2 off 10″ MORGRIP® collet connectors for diver installation, each terminating in an integrated 10″ ASME B16.5 Class 1500 RTJ WN Flange
- 4 off 10″ class 900 MORGRIP® collet connectors, also for diver installation
These connectors were engineered to accommodate the precise flange interface requirements and to ensure compatibility with existing subsea equipment—laying the foundation for a secure, leak-free connection.
What Makes Our Connector Unique
Connector Subsea Solutions MORGRIP® collet connector design exceeded client specifications through:
- Length compensation: Built-in adjustment range to position the flange termination accurately, removing the need for precise metrology before cutting
- Independent grip and seal activation: Allows installers to verify each stage early, ensuring correct engagement before pressurisation
- Mild sour service readiness: Wetted materials subjected to Sulphide Stress Cracking (SSC) tests to confirm resilience in corrosive environments
- Third-party inspection: Every unit was reviewed and certified by Det Norske Veritas (DNV) for absolute quality assurance
Providing Bespoke Solutions
To meet specific field requirements, each connector was fitted with:
- 2 off ½″ NPT grease injection ports, positioned between the grip mechanism and outer seal
- Button-head grease nipples, as per the client’s request
This customisation highlights CSS’s ability to integrate additional functionality without compromising safety or performance.
Delivering Results Through Regional Expertise
Close collaboration with our partners in Thailand (Pipeline and Piling Services – PAPS) played a vital role in the successful execution of this project. With minimal remote support, the PAPS onsite technicians handled the installation with precision and efficiency. This partnership showcased the value of regional expertise, enabling smooth project delivery while reducing the need for overseas mobilisation.
