CALL FOR AUTOMATIC POWER REDUNDANCY IN LIGHT OF BA POWER FAILURE P
ower distribution specialist ide Systems is calling for businesses
to reconsider their electrical infrastructure to ensure reliable power in the event of failure. The call comes after a critical power failure at a British Airways’ (BA) data centre resulted in at least 75,000 passengers being grounded and cost the business an estimated £150million. The critical power failure at BA was reportedly caused by a contractor disconnecting the wrong power supply
at a data centre near Heathrow airport. It is believed that when the power supply was reconnected it resulted in a power surge that brought down the data centre’s uninterruptible power supply and backup power system. While the outage itself lasted for
only 15 minutes, BA was forced to cancel 479 flights on May 27 due to the impact the suspected power surge had on its IT systems. More than 200 services were subsequently cancelled. “While many initially speculated
that it was the result of a cyber attack, the BA incident does underline the important issue of electrical redundancy equipment,” explained Matt Collins, business development manager of ide Systems. “The digitalisation of business has led to IT infrastructure and data access becoming critical to success, yet many businesses prioritise cybersecurity measures over physical redundancies. “Facilities managers must ensure
that their company has the appropriate
power supply redundancy equipment, such as automatic transfer switches (ATS) and automatic mains failure (AMF) panels, to prevent power outages of critical systems. These are designed to facilitate a power supply shift from mains electricity to a backup generator without disruption to service. “Facilities managers must ensure
that their company has the appropriate power supply redundancy equipment, such as automatic transfer switches.

MEGA ENERGY SYSTEM FOR MAKING CACOA
an annual saving of over a million litres of diesel. Theobroma, headquartered in
Alfen is constructing a large and sustainable energy installation for the Theobroma cacao factory in Nigeria. This innovative system combines solar energy, bio energy from cocoa shells and large-scale battery storage for the sustainable production of energy and steam. It guarantees a reliable energy supply and attains a considerable saving on both operational costs and carbon emissions, including
Amsterdam, processes cocoa beans into high-end cacao products for the chocolate industry. As the energy grid in Nigeria is not always reliable, their factory in Lagos currently uses diesel generators. Diesel however, is a polluting and expensive fuel, and its local supply is not always guaranteed as well, causing expensive interruptions in the production process. Theobroma therefore opted for a sustainable alternative that guarantees the continuity and cuts the expensive operational costs.

The first stage of a two part project to integrate the operations of two wastewater treatment works has been completed, with six new, extra large scraper bridges now hard at work at the Oldham, Lancs works. When complete, the new treatment processes will meet higher standards for wastewater management. They will also breathe renewed life into the River Irk and its tributaries, as the water put back into them will be cleaner.

Electric vehicles on the road surged to two million last year, according to a recent report from the International Energy Agency (IEA). If the automotive market is to achieve wider adoption and continue to grow, manufacturers must introduce a hybrid energy approach, combining ultracapacitor battery technology with li-ion to reduce costs and increase efficiency.

A revolutionary new approach to offshore wind turbine installation and maintenance could cut the cost of energy from future deepwater sites by around 9%.
The results of a £200,000 Innovate UK Energy Catalyst study involving detailed engineering analysis on the Self Erecting Nacelle System (SENSE) show the new technology could also trim 4% from the cost of energy at current wind

technology capable of installing the next generation of turbines and towers on foundations in water depths greater than 60m apart from building ever larger and more expensive jack-ups and semi-subs. SENSE Offshore Limited, which is developing the technology for commercial roll out in 2021, says its system means large jack-ups and crane vessels are not needed to install the turbine nacelle and rotor or for maintenance including the change out of major components. SENSE is a modular, removeable transport and installation system mounted on a standard large construction vessel. SENSE Offshore MD Patrick Geraets
says: “Wind turbines are getting bigger and developers want to exploit deep water sites. How are these turbines going to be installed? This product is an answer – faster, cheaper, independent of water depth, with world wide application and it is scalable to the larger turbines coming to market in the next five years.” SENSE transports a pre-assembled and tested rotor nacelle assembly on board a large multi-purpose construction vessel and has solved the problem of transferring 700+tonne loads in significant wave heights from the vessel to the tower. The transportation carriage then carries the turbine to the top of the tower on rails. The process is reversible for maintenance and replacement. The Innovate UK Study was carried
out by a project team of leading contractors including GBG, PHG Consulting, Industrial Systems and Control, BVG Associates, Knowtra and James Fisher Marine Services. It found the System could cut around €125m from the capital expenditure (CapEx) on a €5.1bn, 1200MW wind farm in waters in excess of 70 metres and save €28.5m a year in operating expenditure (OpEx). On a shallower large site where water depths are similar to North Sea farms currently being built with jack-ups, could save €84m in CapEx and €10m in OpEx per year. SENSE Offshore is now planning the next stage of development to bring its technology to market within four years.
