Connector Subsea Solutions
Connector Subsea Solutions (CSS) has successfully supplied large-diameter, thin-wall connectors—subjected to Factory Acceptance Testing (FAT) and hydrostatic testing—for 20″, 8″ and 14″ applications. All connectors have been accepted by the client and are now held in contingency, ready for emergency call-off coverage.
As part of this delivery, CSS supplied a total of 6 off MORGRIP® 3000Ri connectors, comprising 2 off 8″ remote couplings, along with 2 off 14″ and 2 off 20″ remote taper housing assemblies. A key feature of this project was the strategic use of MORGRIP® remote connectors of a single nominal size, engineered to accommodate pipelines with varying diameters and wall thicknesses through interchangeable sealing components.
Rather than fabricating separate connectors for every pipeline variant, CSS designed gripping assemblies capable of accommodating a range of pipe sizes. Only the seal assemblies and inserts are customised per pipeline configuration—offering significant operational flexibility, reduced lead time, and better cost control for our client.
Testing for Multiple Pipeline Configurations
The supplied connectors underwent rigorous testing to ensure their suitability for high-pressure subsea environments. With several notable highlights from the test such as:
- 8″ connector: 200 barg design pressure, hydrotested to 224.5 barg
- 14″ connector: tested across two configurations up to 225.9 barg
- 20″ connector: validated through five configurations, with hydrotest pressures reaching up to 178.8 barg
What’s particularly notable is that the 20″ connector is the largest remote pipeline connector ever designed for thin-wall pipe. This achievement reflects our unique capabilities and expertise in developing sealing and gripping mechanisms for complex requirements.
Driving Innovation in Subsea Pipeline Repair
The delivery of adaptable 3000Ri MORGRIP® remote pipeline connector in this project underscores the versatility of MORGRIP® technology. As operators face growing complexity and variability across pipeline networks, the ability to deploy a single connector model across multiple configurations presents clear advantages:
- Minimised stock requirements for contingency
- Faster mobilisation times during emergency repairs
- Simplified logistics with fewer parts
- Lower overall costs
