Andrews Ventilation safeguards structure of waste-to-energy plant

When excessive temperature differences exist between a concrete structure and its surroundings, thermal cracking is likely to occur. The temperature variance will cause cooler areas to contract more than those exposed to warmer air and eventually leading to the formation of gaps. This scenario is particularly likely in power stations and refineries, where operational conditions regularly see temperatures exceed 400°C.

A newly-constructed plasma gasification energy plant in the Tees Valley recently approached us seeking a ventilation hire package to ensure the structural composition was protected. Non-recyclable products are incinerated on site as part of a process that converts waste into renewable energy.

Large vessel ventilated during restoration

As the UK’s leading provider of ventilation hire equipment, we are very well acquainted with companies operating within a broad range of industries – including refineries and petrochemical applications. Our commitment to working alongside major clients immersed in this field saw us provide a comprehensive ventilation solution for one of the country’s largest oil producers.

This commitment was perfectly encapsulated when a huge FPSO (Floating Product, Storage and Offloading) vessel docked in the North East requiring vital modification and life extension. Typically, these are out at sea for months on end and return to land only for short periods – meaning the timeframe for work to be carried out is always very limited. It was our client’s intention for this formidable ship (250 metres in length and weighing 53,000 tonnes) to eventually produce oil from an offshore field in the North Sea, with an emphasis on the restoration cycle passing as quickly as possible.

Andrews provide ventilation hire solution at a hydroelectric power plant

Before building contractors could oversee the renovation of a tunnel in a hydroelectric power plant, a reliable source of ventilation was required on site. Covering almost 1000 metres, the tunnel was extremely prone to poor air circulation despite the presence of large holes at 180 metre intervals.

Like in many similar instances, the air was at risk of becoming too dangerous for workmen because of the large quantities of dust and dirt produced inside the shaft. This air is extremely toxic if not effectively tackled, leading to purity levels falling well below those outlined in relevant health and safety laws.
