Dalkia converts Sanofi energy centre

A leading global pharmaceutical company, Sanofi engages in the research, development, manufacture and marketing of healthcare products. Holmes Chapel, in the east of Cheshire, is one of four manufacturing sites in the UK, and plays a critical role in manufacturing inhalation products and nasal sprays for global markets.

Dalkia's initial contract to service the site's energy plant over a period of 4 years has recently been extended by a further 5 years. The new contract includes the conversion of the existing steam boiler plant in compliance with INDG436, the Health and Safety Executive (HSE) guidance document for the "Safe management of industrial steam and hot water boilers" that was published along with the "Guidance on the Safe Operation of Boilers" framework (BG01) in 2011.

The renewed contract includes the full servicing of the 725kWe Cogenco CHP installed during the previous agreement term, the operation of the steam raising plant and compressed air plant with mobile labour as well as operational checks and maintenance of the effluent treatment plant. Importantly, the plant's control system has been updated, comprising the installation of new controls, monitoring and alarm equipment on site. These are linked to Dalkia's 24/7 Site Monitoring Centre where technical difficulties are detected at the outset so as to prevent operational interruptions. Round-the-clock emergency response is an integral part of the service.

"These improvements will ensure compliance with the INDG436 and BG01 best practice requirements and increase the plant monitoring capability substantially", explains Mike Robertson, Operations Manager at Dalkia. "Amongst other safety devices we have installed a chemical dosing storage tank, TDS monitoring, feed water hardness monitoring and alarm as well as fire and gas detection and alarm. These systems are indispensable to the safety of those working in and close to the plant and crucial to the health of the plant's equipment. After all, the smooth running of the facility is also a decisive factor in achieving its optimum performance, saving the Holmes Chapel site 1,150 tonnes of CO2 per year".
