Since 1987 we have supplied more than 1,200 subsea connections and 100 subsea manifolds in all major development areas worldwide. Our comprehensive range of systems has the functional flexibility and modular versatility to meet the specific performance needs of any subsea application.

How do we ensure in-service reliability of connector products? All our connector products undergo rigorous qualification testing, and system applications are functionally tested to validate performance envelopes. Our sealing systems are based on proven VetcoGray metal sealing technology and extensive experience. Each project is executed with extensive quality and process control measures for in-house activities as well as any work performed by our approved suppliers and subcontractors.

How do we ensure flexibility to cover a wide variety of applications? We use a modularized design approach, drawing on a range of pre­engineered and standardized building blocks that can be combined in a wide range of application-specific configurations. For subsea manifolds, our configurations cover both cluster and template manifolds, as well as special-purpose applications such as HIPPS manifolds. For subsea connection systems, our portfolio covers pipe sizes of 2-42” and a wide variety of installation scenarios.

How do we ensure a robust project execution process? The same product structuring approach used for product configuration flexibility also helps to pre-define standard interfaces and allows for use of standardized and proven project execution models, including use of pre­approved suppliers and a closely integrated supply chain.

How do we ensure that flow-assurance aspects are addressed? Our subsea manifolds and connection systems are designed with close attention to flow assurance requirements, employing our system engineering expertise and advanced computational fluid dynamics (CFD) modeling capabilities on the design process. Combined with advanced insulation materials and application techniques, our patented GE Heat Bank systems manage cold spot issues to enable extended cool down times and superior thermal management.

How do we accommodate different soil conditions for subsea manifolds? We offer a wide range of pre-engineered foundation systems for various soil conditions, from suction anchors for soft soil conditions via false seabed systems for sloping seabeds and skirted mudmat systems, to piled foundations for hard soil properties. The different foundation systems can be combined with active-leveling features to allow for in-place adjustment of the as-installed condition.

How do we address HPHT requirements? Our designs include options with piping systems and valve configurations specifically for high-pressure and high-temperature (HPHT) requirements – all tested and qualified to the required service level. The connection systems are sized to accommodate the required hub-separation loads by ensuring sufficient preload margin for any given bore size through a parametric design approach based on the VetcoGray metal sealing technology and experience.

How do we make our systems installation friendly? Installation ease is a key factor of our design process. Our manifold systems accommodate a number of installation options, including rig deployment and midwater tow, to minimize the need for heavy lift vessels and to accommodate large installation tolerances for foundation systems. Connection systems accommodate efficient installation and maximized versatility and flexibility for pipelay vessel requirements, for either reel, J or S-lay installation. For large trunk-line connections, we have developed the patented Lift & Shift system that enables large bore pipelines to be installed from S-lay vessels without the need for large pipeline end termination structures (PLETs) to be deployed through tensioners and over stingers.

ICARUS connection system ICARUS is a fully ROV-operated, pull-in and connection system for tie-in of flexible flowlines, umbilicals and rigid spools up to 18" ND. An integrated subsea winch and powerful alignment system provides high operational efficiency and ability to cover a wide range of tie-in applications, including patented mini riser base connections.

Horizontal clamp connection system (HCCS) This is configured as a simple and robust horizontal stroking system for rigid pipe spools and flexible flowlines. A short nominal stroking distance, high alignment capacity and high in-place connector load capacity combine to make our HCCS well suited for large-bore pipe-spool connections. For large pipelines, the patented Lift & Shift deployment configuration can be used to eliminate the need for large PLETs/pipeline sleds through the pipelay vessel’s tensioners. Our HCCS design includes a swivel feature to accommodate connection of flexible flowlines, as well as a stab and hinge-over (S&HO) version for umbilical connections. The HCCS utilizes our standard range of clamp connectors, available in a wide variety of sizes.

Vertical clamp connection system (VCCS) This system is designed for simple and reliable vertical connections of flexible flowlines and rigid pipe spools. A gooseneck configuration with integral lifting features is used for flexible flowlines . A special funnel system forming part of the connector assembly provides passive alignment, and an ancillary stroking tool can be used to provide additional alignment capacity if needed. Just as with our HCCS, the VCCS utilizes our standard range of clamp connectors and can thereby be used for a wide range of connection sizes.

Vertical connection module (VCM) This connection system is used for direct lay-away connections of flexible flowlines. It utilizes well-proven collet connectors with integral hydraulics, configured with a robust funnel based alignment system, integral soft landing features and a gooseneck interface to the flexible flowline. A special metal sealing swivel system allows for easy orientation during deployment and connection operations.

6" VH connection system The 6” VH collet connector system is intended primarily for vertical connection of rigid spools, and it is frequently used for flexible flowline and flexible jumper connections. The 6" VH utilizes a mechanical, non-integral collet connector system deployed together with a running tool for actuation. The running tool also provides soft-landing features and additional alignment capacity.

DG and DG-2 mandrel connector system Mandrel connectors resemble collet connectors, but generate the sealing preload with serrated locking dogs instead of collet sleeves. Our range of mandrel products for flowline connections includes the DG and DG-2 connectors. The basic DG connector is a proven design based on integral hydraulics, with operation through an ROV panel and with the seal fixed to the connector. The DG-2 connector is a design evolution of the DG model and accommodates subsea seal replacement. The DG-2 connector can be operated through integral hydraulics and in non-integral mode using an ROV-carried stroking mechanism.

ROV stab connectors Our 2RSC ROV stab connector is designed for high integrity, metal-to­metal connection of larg-bore ROV jumpers up to 2" ID, and is typically suitable for gas lift or methanol/MEG service. It utilizes the patented SX metal sealing technology, which is also used for hydraulic couplers in multibore hub applications. The 2RSC ROV stab connector is fully ROV operated without need for special tooling, and it can be configured for use with thermoplastic hoses and rigid pipe.

Thermal insulation From a flow-assurance standpoint, flowline connectors often constitute a cold spot that needs attention during design of the thermal-insulation system. This is of particular importance in deepwater applications where high ambient water pressure contributes to increased hydrate-formation risk. The traditional response to the cold-spot issue is to retrofit a “doghouse” cover outside the connector, insulating it from the ambient seawater.

As a supplement to traditional syntactic foam-based doghouse covers, GE has developed and patented the Heat Bank system that employs a wetsuit principle where seawater is trapped around the connector, providing improved thermal properties. An added benefit of the Heat Bank system is that it can be installed with the connector to eliminate need for a separate retrofit doghouse installation.
