Quark Expeditions, an operator of polar exploration cruises, has contracted Evac to supply Cleantech water and waste systems, including a ballast water management system (BWMS), for its latest vessel, in order to ensure minimal impact on the environment.

The new expedition ship, designed to carry up to 200 passengers, will be built by Brodosplit in Croatia and is scheduled to be launched in 2020.

“We are confident that the Evac Group will be a perfect partner for us in the execution of the vessel,” said Tatjana Mlinaric, Senior Contracts Manager at DIV Group, the Brodosplit mother company. “We are very satisfied with the service provided so far and look forward to delivering a vessel with state-of-the-art waste, water and ballast water management systems”, she added.

Evac has worked closely with Norwegian naval architec LMG on the design of the systems. “We have had excellent co-operation with Evac during the design phase enabling the project to move smoothly and ensuring that ship has the most advanced and cost-effective equipment package”, said Torbjorn Bringedal, MD of LMG.

This will be the first time that a BWMS has been incorporated into Evac's Complete Cleantech Solution package, following Evac’s acquisition of Cathelco, the UK manufacturers of marine equipment, in 2018. The Evac Evolution BWMS was developed over a 10 year period by Cathelco. The system supplied for Quark Expeditions will have the capacity to treat 75m3/h. Based on a combination of filtration and UV technology, it has a ‘feedback loop’ which uses UV transmission as the parameter for precisely determining UV dosage, ensuring effectiveness in challenging water conditions, and saving power. USCG Type Approval is pending.

Evac will be installing Optima 5 vacuum toilets on the ship connected to two online vacuum generation units resulting in savings in water usage. Onboard black and grey water requirements will be covered by an Evac EcoScreen pre-treatment plant and membrane bioreactor wastewater plant, certified to meet the most stringent standards of effluent water, nutrient and phosphorous removal.

The contract includes a marine growth prevention system to eliminate blockages in seawater cooling lines, involving copper and aluminium anodes in the seachests connected to a control panel.

A fully integrated system including grease traps will process waste from the galley. The ship will be equipped with a food waste collection tank and several macerator units as well as a heavy duty food waste shredder connected to a centralised vacuum waste system.

“I think this is the first of many projects where the combined strength of Evac and Cathelco will enable us to win new business by offering a more comprehensive range of the products, particularly as the market for ballast water management systems gathers momentum”, said Kjell Erik Reinstad, GM of Evac Norway.
