Asset helps power potential of biomass plant

Using the Weholite product with welded joints, the HDPE pipe becomes a homogeneous pipe line, capable of withstanding ground settlement without compromising its structural integrity. To further combat the issue of poor soil modulus, a geo- grid was installed to increase ground stabilisation and minimise settlement. With the tank being positioned under a log storage yard, where it would be subjected to heavy loads, it was also important for it to be able to withstand a worst-case load of 420 kN on a single wheel of a Liebherr LH50 log loader. Weholite has a natural ability to ‘flex’, which enables the pipe to adjust to different loading conditions, vibrations, stress and soil movements, without causing damage to the structure. Asset delivered the project over a two- week scale, saving the client weeks on its initial projections. Commenting on the choice of Weholite plastic tanks and pipes, Simon Collins, contracts manager at BWSC, said, “The Kent scheme is BWSC’s eighth turnkey biomass power plant project in the UK within the last five years, and the close cooperation with key industry partners, including Asset, has contributed to the successful delivery of the projects. We have been extremely impressed with the quality of the Weholite product, which has not only effectively addressed our project requirements, but saved us time and provided excellent value.” Asset International technical sales engineer Matthew Thomas said, “This is a highly successful project and has really cemented a strong working relationship between Asset International, our client BWSC and the installation company NBC Construction UK. Weholite was the ideal solution for BWSC’s project requirements thanks to its superior performance in poor ground conditions, long service life and reliability.” Asset International Ltd – UK

The company provided its expertise to Danish engineering and contracting company Burmeister & Wain Scandinavian Contractor (BWSC) on a surface water attenuation system for a new biomass power plant being developed by the company in Kent, UK. BWSCundertookaproject to reduce the region’s carbon footprint and reliance on imported fossil fuels by providing a secure source of renewable heat and energy through a new combined heat and power (CHP) biomass plant.

With growing global demand for energy and an increasing acceptance that fossil fuels and nuclear power are not only unsustainable but also damaging to the environment, developing renewable and sustainable energy sources has become an important necessity. Asset International has provided solutions to a number of renewable energy schemes around the world. Its Weholite HDPE pipes have been implemented in a range of projects throughout the UK and further afield.

Powered by locally sourced virgin wood, the plant will generate approximately 27.8 MW of green electricity, capable of supplying up to 50,000 homes. Having already supplied smaller diameter pipes to the site for general drainage purposes, and with experience working on renewable energy schemes, Asset International was chosen by BWSC when looking for a manufacturer to lend its expertise in water management solutions for the project. Due to the site’s poor ground conditions, BWSC was looking to integrate a surface water attenuation tank to store surface water drainage and avoid ground settlement in the overlying log storage area. To achieve this, Asset provided a comprehensive design service and developed a bespoke solution tailored to the scheme’s requirements. Construction works in connection with the tank were provided by NBC Construction UK. The result was a multi-leg attenuation tank: a 940m³ six-leg tank of 2.2m diameter HDPE pipes, with fabricated manifolds at each end and a fully welded system to ensure resistance to impact.
