Strohm, a leading thermoplastic composite pipe company, has added jumpers and flowlines for CCS applications to its portfolio, having successfully qualified its first product based on carbon fibre and advanced PVDF polymer

PVDF is a high performance polymer with a 30-year design life and a proven smaller carbon footprint compared to steel. Offering total corrosion resistance, it is highly suitable for injecting CO2 offshore, both in depleted gas fields and aquifers. With a long track-record in oil and gas, PVDF also has a very high chemical resistance and higher temperature capability.

Potential to withstand high temperatures and pressures

It is also strong enough to withstand the high temperatures and high pressures associated with ultra-deepwater hydrocarbon production, and provides a high level of natural insulation. As well as its potential for CCS applications, Strohm’s new TCP product could also revolutionise the deepwater flowline and riser market in the offshore energy industry.

Martin van Onna, Strohm CEO, said, “This is a hugely momentous breakthrough for the company, one that has been a long time coming. It has taken us more than 15 years, a lot of hard work and a huge amount of testing to get to a place where we are now able to offer a TCP product based on carbon fibre and PVDF.

“There is a big future for this innovative solution, both in CCS and in conventional offshore energy, and we look forward to working with companies to help them realise the value that TCP can bring to their projects.”

Celeros Flow Technology has up-scaled its Bandlock2 quick-opening closures so they can be incorporated on very large diameter pressure vessels and pipelines

The need for larger diameter closures is being driven by the fact that pipelines and pressure vessels are getting bigger, as a result of the growing global demand for essential products such as water, gas and oil. Available in diameters up to 100 inches (254cm), the larger diameter Bandlock2 closures offer customers the potential to reduce the number of pressure vessels and associated pipework required for any given application.

Same quick-opening mechanism

Manufactured by Celeros FT brand GD Engineering, very large diameter Bandlock2 closures offer the same proven quick-opening mechanism and sealing design as standard diameter closures. Full access is still achievable in less than a minute. They feature a unique, self-energising lip seal with integral anti-extrusion spring and offer full vacuum capability.

A hand-operated pressure warning screw assures safe operation. This is integrated into the closure mechanism and prevents the door from being unlocked until it is confirmed that the vessel’s internal pressure has been relieved. Additional secondary safety features, such as mechanical key interlocks, can be fitted and integrated with control valve operations. In addition, the locking band can be seen at all times, which satisfies design code requirements and means that the operator can actually see that the door is securely closed and locked.
