BP Norge has chosen to implement Sandvik Riser Technology’s Clikloc connector technology in its tree running tool operations as well as its coil, wire-line operations.

Suitable for use in the harsh environment of the North Sea, Clikloc is a rapid-action connector for demanding topside and riser applications on oil and gas rigs.

Its use simplifies tube connections, helping to improve both safety and efficiency while reducing make and break times by as much as 80 per cent.

Clikloc is designed to improve efficiency by reducing rig-up/rig-down times, taking approximately 10-15 seconds per connection.

This compares favourably with conventional connectors that can take up to an hour to assemble.

Based on male and female parts that form a seat for the sealing ring, the connector comprises a radial extending annular stem with a first and second axial seal support portion.

The female part is axially assembled to the male part and, as a result, compresses the seal support portions, making the sealing area compress in a radial direction.

The new technology reduces the time taken in performing a drill stem test to evaluate surrounding geological formations when a landing string system is connected to the wellhead.

Using traditional technology, the last connection of the landing string is made by rotating the assembly below the surface flow tree after first disconnecting hoses and other connectors.

By employing a Sandvik Clikloc connector for the last connection below the surface flow tree, the connection can be made without any rotation of the surface flow tree; this eliminates the need to disconnect any hoses or other connectors.

The design of the connector is in accordance with detailed specifications combined with performance qualification testing and Det Norske Veritas (DNV) certification.

All parts are fully tested and assigned a serial number for tracking and full traceability.

The connector is rated for operational pressures of up to 10,000psi.

Titanium grade 28 is used for the metallic seal of the connector; thanks to its improved mechanical strength and low e-module, it is said to give excellent values as a seal ring material.

The body of the connector is manufactured in Sandvik SAF 2507 super-duplex steel using the hot isostatic pressing (HIP) of gas-atomised powder.

HIP products are completely dense, homogeneous and isotropic.

This improves the product’s fatigue life by around 20 per cent compared with carbon steel.

The design makes Sandvik Clikloc ideal for use in narrow and constricted spaces.

It has a flush bore that prevents objects from internal obstruction anywhere along the line.

Typical applications include coiled tubing stack-up risers, tree running tool connections and flow head connections.

Sandvik Clikloc provides simplified tube connections, increasing both safety and performance.

It reduces downtime because there is far less chance of malfunction than with a standard connection; it also provides quicker, more reliable general performance and is a natural successor to conventional couplings for both offshore and onshore applications, according to Sandvik.
