Vertical Tie-in Systems

Vertical Tie-in Systems

Vertical Tie-In Systems Vertical Tie-in systems may be used for tie-in of flexible flowlines, umbilicals, Jumper spools, Rigid Spools and Inline Tees. Vertical connections are installed directly onto the receiving hub in one operation during tie-in. Since the Vertical Connection System does not require a pull-in capability, it simplifies the tool functions, provides a time efficient tie-in operation and reduce the length of Rigid Spools. FMC has developed a series of Vertical Tie-in connectors to make any vertical Tie-in effective. FMC Vertical Connection Systems These systems provide vertical Landing and Connection for the 1st and 2nd end of flexible Flowlines, Rigid Jumpers, Rigid Flowlines with flexible tails, Flowline Risers and Umbilicals. Vertical Connection Systems may connect of up to 30 OD (27 ID) to Manifolds, Xmas Trees, Sleds, PLETs and PLEMs. These systems have no interference with the seabed during installation and connection, increasing the subsea visibility during installation. The Vertical Connection systems does not require flowline pull-in capability, simplifying all functions and providing a time efficient subsea tie-in operation. Stroking and connection is carried out by the the Connector itself, or by the ROV operated Connector Actuation Tool (CAT) System. FMC Tie-in Experience As development of Subsea fields reach the depth limit for diver operation, diverless Tie-in systems become an issue. FMC designed and operated the first diverless Tie-in & Connection system ever on the Gullfaks field for Statoil in the North Sea in 1986. Since then, many new innovative Tie-in solutions for deep and ultra-deep waters have passed through our work-shop to satisfy clients world-wide. FMC have now a family of Tie-in & Connection systems, all based on standard interfaces. These reach from the smallest hydraulic Flying Leads, to large bore Export lines in both Vertical and Horizontal, and Monobore or Multibore configurations.

Testing of equipment and training of personnel onshore is vital to success in this offshore operation. FMC has developed a Subsea School for training of Clients representatives alongside training of own service personnel. The good chemistry developed during this training period has resulted in a unique track record of successful offshore operations. The Customer Support headquarter in Bergen is the single point of contact for all expertise, personnel, systems and tools needed for installation and life-offield management and support. We provide service and strategic life of field planning and solutions designed to deliver immediate and long-term satisfaction to operators worldwide.

Vertical Tie-In Systems Vertical Connection may be made up by integrated hydraulic connectors, by non-hydraulic mechanical connectors with assistance from a Vertical Connector Actuation Tool (V-CAT) and ROV, or by a Clamp Connector. Mechanical Connector The mechanical Collet connector with the V-CAT (Vertical Connector Actuation Tool ) is lifted directly onto the receiving hub. The V-CAT incorporates a soft-landing device. This connection system leaves no hydraulic components subsea. The Vertical connection system ( V-CAT ) is very compact, requires minimal mobilization, and is air transportable world-wide. Hydraulic Connector The hydraulic Collet connector is lifted directly onto the receiving hub, and operated directly from the ROV. With no need for a dedicated actuating tool, this Tie-in method requires minimal mobilization and tool logistics. Clamp Connector The mechanical Clamp connector is operated from the ROV by a Torque Tool. The Clamp is located onto the receiving hub, and operated directly from the ROV. With the assistance of only a Torque Tool, this Tie-in method is a very efficient way of making up large bore Export line and Riser Connections.

Vertical Connection Options Torus Tie-in System This Tie-in System Is based on the TORUS Hydraulic Connector. This connector has all hydraulic tie-in functions incorporated in the connector and consequently requires no tool for operation. The Torus connection system is suitable for up to 18 ND flowlines. Hydraulic lock/unlock design Hydraulic secondary release mechanism Mechanical override feature Positive pre-load via flat-to-flat locking mechanism Primary Metal to Metal seal, secondary non-metal seal External seal test feature for subsea verification of proper connection MAX Tie-in System This Tie-in System Is based on the MAX Mechanical Collet Connector. The MAX connector is a robust 15ksi design developed for high jumper load (i.e. HP / HT) conditions. This Connector design leaves no hydraulic components subsea after installation. Make-up of the Collet Connector is performed by the Connector Actuating Tool (CAT), operated by the ROV. Hub inspection and cleaning prior to connection is performed by ROV with dedicated tool package. The MAX connection system is suitable for up to 14 ND flowlines. Working pressure up to 15,000 psi MAX-8 designed to accommodate up to 8 pipe; MAX-14 up to 14 pipe High bending, torsion and preload capabilities for HP / HT applications All hydraulic components for Tie-in integrated in CAT Positive pre-load via flat-to-flat locking mechanism Primary Metal to Metal seal, secondary non-metal seal CAT performs hub alignment, soft land and boot strap during installation CAT performs external Lock/Unlock and secondary unlock of MAX connector VECON Mk1 Tie-in System with KC Hydraulic Connector Vertical installation and connection system for Rigid spools and flexlines. Suitable for up to 30 ND flowlines and umbilicals. Based on the Integrated hydraulic KC Connectors. To be used in both Mono & Multibore configurations. VECON Mk2 Tie-in System with KC Mechanical Connector With the CAT-V2 mounted directly on each collet connector, this connection system is a time efficient way of connecting lines. Since the VECON system does not require a pull-in capability, it simplifies the tool functions and provides a time efficient tie-in operation. The connection system (CAT-V2) is very compact, requires minimal mobilization, and is air transportable world-wide. Vertical connections are installed directly onto the receiving hub in one operation during connection. These systems have no interference with the seabed during installation and connection, increasing the subsea visibility during installation. Based on the KC Mechanical connectors, this connection system leaves no hydraulic components subsea, and may be used in both Mono & Multibore configurations.
