Connectors

CR-R1 Remote Connector

The CR-R1 is a conducting pipe connector used during the drilling stage on jack-up self-elevating type platforms where diverless release of the conductive pipe is required. The CR-R1 is launched jointly, a male part and a female part, the male remaining in the well after the drilling operation is over.

The FC1 Fast Connector is used for later reconnection.

 

 

FCL1 Fast Clamp

The FCL1 fast clamp is of the quick-connect type used in interface with the on-shore and off-shore wellheads. Its design takes into consideration flexuring loads, shear-stress resistance, and allows the clamp to be positioned according to needs.

 

 

FC1 Fast connector

The FC-1 fast connector, used on our subsea Christmas trees, is compatible with the male CR-R1, it is of the weight-set type for easy installation and able to withstand the most extreme load conditions in the subsea environment. It only requires involvement of the diver or the ROV at the time of disconnection. It is also available with a hydraulic disconnection system.

 

 

No-cross couplings

They are no-cross couplings with buttress threads as an alternative design to the API standard. They are pre-aligned at the top to provide a guide and ensure optimal connection.

 

 

Threaded connectors

They are 2½-turn threaded quick-connects with double seal, pre-aligned threads and low torque, which ensure a connection not requiring mechanical tools. Available in 20" diameters and larger.

Subsea Xmas Tree

Model BB-200 GL/DO (Guide Line / Diver Operated) subsea Christmas trees have an optimized and economical design for better performance to meet the needs of the client. Its simplicity reduces installation time and decreases the number of operations performed by the diver, affording higher safety and saving installation time. The BB-200 subsea trees are used in shallow waters together with Mudline MJ1 system and allow several satellite wells to be connected to one and the same platform, which results in a better cost/benefit ratio.

  • Low cost and maintenance.
  • Trees designed for single or multiple completion.
  • Metal-metal seals in interfaces with the environment.
  • Independent control line for subsurface safety valve (SCSSV).
  • Available in different materials for all services.

Mudline Suspension System

MUDLINE - MJ1

The mudline suspension system used in off-shore wells allows the casing string of an oil or gas well to be suspended and anchored directly on the seabed, transferring all the weight to the mudline. It is used in shallow waters, up to 100 meters approximately, and drilled from jack-up platforms. It is ideal for wildcat wells, as it allows for temporary abandonment and subsequent reconnection, releasing the drilling rig without leaving any installation fixed to the location. The completion can be dry, by installing a wellhead and Christmas tree on a fixed platform, or wet by using a subsea tree.

SSC COMPACT SUSPENSION SYSTEM

The SSC compact suspension system is a simplified and low-cost alternative in cases where it is not necessary to abandon the well. As with the MJ1 system, it allows the casing pipe to be anchored to the sea floor, transferring the entire weight of the casing to the mudline. It is an ingenious solution that makes the SCC a versatile and safe system ensuring a rapid and reliable operation.

Subsea Gate Valve

Gates valves are normally closed, and they can feature either a hydraulic or manual actuator.

The hydraulic actuator has a built-in manual override that allows the diver or the robot to open or close the valve manually.

It is intended to operate at pressures from 1,500 up to 3,000 PSI. It can be provided with a position indicator.

Null

 

  • Designed as a safety system (FAIL CLOSE) for subsea applications.
  • Compact design.
  • Mínimum number of parts.
  • Sealed threads 100% watertight.
  • Linear and rotating override available for intervention with ROV
  • Available for different valve sizes, pressure ranges, and depths
