Ancillary equipment Elcome unveils latest
switchboard Elcome International has announced the introduction of the new ELSYS family of marine electrical switchboard and power management systems. The ELSYS systems use design technologies with
new-generation switch-gear components to reduce the size and weight of the switchboards. Te modular design allows flexibility to satisfy performance requirements and meet space limitations.

lamps, increasing the efficiency of the process and ensuring that all organisms and bacteria are rendered harmless, says the company. UVT sensors positioned in front of the reactor chamber,
constantly measure the UV transmittance of the water and send a signal to the control panel which automatically adjusts the power to the lamps. Another important feature is the unique ‘ball’ cleaning system which ensures that the surfaces of the quartz sleeves surrounding the UV lamps are kept clean. When the cleaning cycle is initiated the UV chambers are isolated from the rest of the BWT system. A separate pump is activated enabling specialised foam balls to be introduced into the chambers from a reservoir. Tese gently polish away any residue that may have collected on the glass as well as cleaning the inside of the UV chamber, reducing the risk of corrosion, says Cathelco. Tis approach eliminates the use of chemicals and overcomes the potential for damage when using mechanical cleaning methods. Te system is currently completing land-based tests at
the NIOZ research facility in Holland and, at the same time, shipboard tests are taking place on Eddystone, a ro-ro vessel owned by Foreland Shipping and managed by Andrew Weir.

Ballast water treatment systems Elcome announces extension of its switchboard range Ballast water treatment system Cathelco launches BWTS
Cathelco has launched its ballast water treatment system on to the market. Te Cathelco BWT system is based on a combination of filtration and UV technology. Te units are scalable for all sizes of ships and will be available with capacities from 50m3
/hr to 2,400m3 /hr. One of the key design features is the way in which the
sea water passes through the UV chambers. Trough computer analysis, Cathelco engineers have produced pipework which sends the water on the unique trajectory which creates a ‘helix’ in the flow. Tis means that the maximum surface area of the water is exposed to the UV

in-voyage BWTS Coldharbour Marine is set to bring a change to the ballast water treatment (BWT) market with its Sea Guardian technology. The patented third generation Inert Gas Generator system (3gIGG) can be used onboard any vessel, but aimed at the gas carrier and bulk carrier market. Te Coldharbour Marine GLD ballast water treatment
system uses the gas output for its Sea Guardian inert gas generator that is linked to specially designed gas liſt diffusion pipe assembles inside the ships ballast tank. During the voyage, the output from the IGG is
pumped to the GLD in the ballast tanks where the treatment takes place. Te system is capable of handling water with high levels of suspended solids. Tere are no mechanical filters to block or back flush, no complex electrical systems and no space consuming equipment, says Coldharbour Marine. Te ballast water is also treated whilst the vessel is underway and does no disrupt the vessel’s operating schedule. The Coldharbour Marine GLD ballast water
treatment system is a G8 type system as defined by the IMO. Te system is under the flag state approval of the UK Maritime and coastguard Agency (MCA) and Lloyd’s Register. Te system has completed land based testing and is undergoing testing on a VLCC, under both IMO and USCG testing perameters.
