IMO APPROVAL FOR LATEST EVAC BWMS

Monday, May 13, 2019 

The Evac Evolution Ballast Water Management System (BWMS), which is designed and manufactured by Evac group company Cathelco, has been granted IMO Type Approval.

The system has been tested to the revised G8 standard and the recently introduced Ballast Water Management Code. “We are delighted to have achieved IMO Approval to the latest standards. It means that customers can have complete confidence in buying our equipment because we have had to prove that our design limitations are accurate and that the system operates reliably in real world conditions”, said Lauri Laaksonen, CTO, Evac Group.

The Evac Evolution BWMS is close to attaining US Coast Guard Type Approval having been on the pending list since November 2018. The Cathelco Mk1 BWMS was IMO Type Approved in 2014, followed by USCG AMS Approval.

The latest tests were conducted at the MEA facility in Holland with Lloyd’s Register acting as the independent laboratory working under the Flag State regulations of the UK’s Marine & Coastguard Agency.

The Mk1 BWMS has been operating reliably on vessels as diverse as container ships, ro-ro cargo vessels, offshore support vessels, fishing craft, luxury cruise ships and superyachts.

IMO's Ballast Water Management Code subjects equipment to greater scrutiny in terms of realistic ‘scaling’ in relation to flow rates, sediment loads on filters and closer examination of the efficacy of the system in comparison with holding times. “Our system has met all of these criteria without compromise,” said Field. “We set the objective of achieving effectiveness down to 55% UVT in all salinities and we have adopted linear scaling which means that it will work on all types of vessels”, said Robert Field, Cathelco technical director.

The Evac Evolution BWMS, based on a combination of filtration and UV technology, incorporates a feedback ‘loop’ based on the measurement of UV transmission which determines precise dosage. It automatically adjusts to different seawater qualities in harbours and estuaries ensuring the optimum UV dosage is applied at all times, but saving on power whenever possible. Effective in fresh, brackish and seawater it is available in capacities from 34m3/h to 1,500m3/h in a single unit. Systems can be supplied skid mounted or in modular form for easier installation in confined areas.

“At an early stage, we opted for UV transmission as the parameter for determining UV dosage. I think it is only a matter of time before this becomes a mandatory requirement and in this sense, customers who buy an Evac Evolution system are already ahead of the game”, said Field.
