Merford applies new noise control technology to a London transformer station
In the heart of London, the transformers of a power distribution station could be heard by local residents. Merford installed an acoustic screen with the NoiseTrap® technology developed by Sonobex. A revolutionary metamaterial technology where sound is passively cancelled in the panel and natural ventilation is also possible. Network operator UK Power Networks was the first to successfully use this technology for the substation in the Bayswater district, London.
Unique control unit for Next Generation Gangway of Barge Master and Bosch Rexroth
Barge Master is a supplier of motion compensation systems for the offshore industry. The Next Generation Gangway is the company's latest innovation. The system transfers people from a ship to, for example, offshore wind turbines or platforms. The machine compensates wave motion, and at the same time stabilizes the gangway for people walking over it. The gangway is also applicable as a crane for light loads. The unique open control unit of the gangway was designed and produced by Merford Cabins, in extensive consultation with Barge Master and Bosch Rexroth.
Noise control for transformers West of Duddon Sands Offshore Wind Farm
On behalf of Royal Smit Transformers, Merford Noise Control has developed a set of sound-insulating enclosures for the large power transformers and shunt reactors of an offshore wind farm. The enclosures have been equipped with sound-insulated ventilation systems. This combination limits the emission of noise to a sound power level of 70 dB(A).
Unique operator cabin for Solitaire offshore pipelay vessel
On behalf of ELMA, Merford has produced a custom-made cabin for the Solitaire owned by Allseas, one of the largest pipelaying vessels in the world. Pipes are welded together on this type of vessel, after which they are lowered to the bottom of the sea as a single unit, and carefully laid down in the right position. Based on a line of sight analysis, Merford developed and produced the most ideal cabin based on the characteristics of the crane and the ship. The cabin is equipped with various innovations that enable to operator to work more efficiently and which enhance his safety.
Achieving effective Active Noise Reduction in a transformer station in a residential area
A transformer station owned by Westland Infra Netbeheer in the Dutch town of Poeldijk has recently been fitted with an Active Noise Reduction (ANR) system. This makes use of a technology which is also known as anti-noise. There were plans to build new houses close to the transformer station so the transformer station had to meet certain noise requirements. Merford was asked to find a way to reduce the noise pollution levels to a maximum of 40 dB, at a distance of 21 metres on the side of the station where the houses were to be built. An ANR solution was developed to be installed in the transformer station so the sound emissions were reduced to the required levels.
