Connection Systems
Trendsetter's continued expansion of the TCS product line meets the ever evolving needs of our customers and industry. The TC2 product line welcomes a hydraulically actuated connector, ideal for intervention and service applications due to emergency quick disconnect capability and optional fluid retention poppets. The clamp connector family has been expanded to include the TC16 to handle large flowline jumpers up to 16” bore. Paired with the development of the TC16 has been a growth of the TEX gasket line to include TEX-13 and TEX-16 sizes.
The Trendsetter Connection System (TCS) is a family of subsea connector solutions developed to meet industry needs for reliable, innovative connector products. All TCS products have been designed around lessons learned, research and feedback on existing subsea connection systems available to the market. The heart of the TCS is Trendsetter’s proprietary metal to metal (MTM) gasket system, TEX. The development of the TCS positions Trendsetter to offer products to our clients which meet and often exceed requirements with unparalleled levels of quality, service, competitive pricing, and fast delivery.
All products are designed, built, and tested in Houston, Texas, USA. The TCS family includes the following products:
- TC2 Collet Connector
- TC7 Clamp Connector
- TC11 Clamp Connector
- TC16 Clamp Connector
TC2 Collet Connector
The TC2 Outboard Connector is a collet latched, subsea installable and recoverable horizontal or vertical connector that was developed with direct industry feedback regarding the complications and lessons learned associated with existing 2” style connectors. The TC2 has addressed issues around packaging, subsea deployment, and operation with a simple, efficient design based on three main principles: robustness, reliability, simplicity.
Features and Benefits of the TC2 Collet Connector
- Robust collet latch mechanism and a simple effective load path for connection pre-load, provides class-leading capacity.
- Small, compact, recessed hub and connector system is easy to package on crowded tree ROV panels.
- Metal-To-Metal TEX-2 gasket enables back seal test and subsea seal change, features that are unmatched in other connectors of this size.
- Inboard hub receptacle that allows for misalignment of five degrees during installation and provides a hard landing shoulder to prevent damage to the hub, gasket, or latch mechanism.
- Actuating sleeve provides protection for collets and gasket during handling, transportation, deployment, and ROV installation activities.
- Innovative secondary release mechanism is isolated from load during normal operation. Secondary release is effected using an external ROV deployed tool. Surface redress of the connector requires a few small components and only minutes to complete.
- Optional alignment key can be installed if needed, otherwise the TC2 can be installed in any orientation – 360 degrees around the hub axis.
- Utilizes readily available, standard ROV API 17D Class 4 Torque Tool and Hot Stab for operation.
TCS Clamp Connector
The TCS 3-piece clamp connection system is a fully integrated connector product complete with hubs, clamp, and alignment structures in a simple, efficient package. The TCS clamp utilizes a standard API torque tool to make up the lead screw and preload the TEX gasket. The torque bucket is equipped with a simple turn count indicator and mechanical secondary lock.
The clamp housing and softland cylinder are integrated into the outboard alignment structure to save space, simplify packaging and streamline installation. The alignment structure features provisions for the pull down/lift tool interface and windows to facilitate subsea seal change. The TCS clamp connector is available in three sizes and has been qualified to accept a range of gaskets up to 16” ID with sufficient structural capacity to support large jumpers with pipe sizes up to 20”.
TC7 Clamp System
The TC7 3-piece clamp is targeted for well and small flowline jumpers, accepting a range of gaskets up to 7” ID and is operated with a standard API Class 5 torque tool.
The TC7 is API qualified to:
- 5” bore up to 20,000 psi internal pressure and 400°F
- 7” bore up to 15,000 psi internal pressure and 400°F
TC11 Clamp System
The TC11 3-piece clamp system is the mid-range clamp size for larger flowline jumpers. The TC11 accepts gaskets up to 11” ID and is operated with a standard API Class 6 torque tool.
The TC11 is API qualified to:
- 5” bore up to 20,000 psi internal pressure and 350°F
- 7” bore up to 15,000 psi internal pressure and 350°F
- 9” bore up to 15,000 psi internal pressure and 302°F
- 11” bore up to 10,000 psi internal pressure and 302°F
TC16 Clamp System
The TC16 3-piece clamp system is the largest clamp size for gathering and export line jumpers. The TC16 accepts gaskets up to 16” ID and is operated with a standard API Class 7 torque tool.
The TC16 is API qualified to:
- 7” dual bores up to 10,000 psi internal pressure and 250°F
- 13” bore up to 7,500 psi internal pressure and 250°F
- 16” bore up to 7,500 psi internal pressure and 250°F
