Subsea development continues at an ever-increasing rate, opening new markets and offering new design opportunities.

As the use of flexible risers and umbilicals progresses into deeper waters the requirements of the clamping system used to maintain the buoyancy’s position along the line has become more challenging.

The range of variables encountered through the design life of the clamping system includes variation in flowline/umbilical diameter due to changes in internal pressure, flexing, temperature and tension fluctuation.

Balmoral leads this specialised market by offering innovative and reliable solutions that address extreme depth operations by utilising high performance clamps that have an uncompromised track record.

Complementing its patented integral and premium clamp products the company recently improved its three-piece design enhancing the range of clamping options available.

The upgraded clamp comprises a unique, patent-protected, reinforced polymer layer that reacts across the opposing faces to provide increased stiffness and reduce the effect of system creep over the installation lifetime.

The configuration of the three-piece clamp allows for standardisation across a range of design criteria that assists with product selection, is cost-effective and minimises product installation time.

Complementing this low-cost product solution, the clamp can be supplied with a simple and effective installation tool that utilises Balmoral’s patented direct-loading clamping methodology.

In contrast with relying on displacement and controlling load application through gap monitoring between segments, Balmoral’s three-piece clamp installation tool applies the clamp load directly. This method is far more accurate regarding the final system load as it remains constant, regardless of pipeline tolerancing, expansion and contraction.

Engineering and projects director, Fraser Milne, says: “Our unique creep resistant three-piece clamp solution, combined with the direct-loading installation tool, is ideally suited to short lead-time projects.

“Its highly competitive performance and availability will establish the three-piece clamp as a key option in Balmoral’s comprehensive clamping product range.”
