Polar expedition cruse ship operator, Quark Expeditions new ship will be fitted with an Evac Complete Cleantech Solution that now includes a ballast water management system (BWMS).
The new expedition ship designed to carry up to 200 pax 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, Brodosplit’s parent. “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.”
Quark Expeditions vessels sail in some of the most fragile environmental areas and the company said that it is committed to being one of the most environmentally friendly operators.
Over the last five years during the development stage of the vessel, Evac has worked closely with LMG, a Norway-based naval architect who designed the new cruise ship.
“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, LMG managing director.
This is the first time that a BWMS has been incorporated into the Evac Complete Cleantech Solution package, following Evac’s acquisition of Cathelco, in 2018.
Evac Evolution BWMS has been developed over a 10-year period by Cathelco. The system supplied for the Quark Expeditions vessel will have the capacity to treat 75 cu m of ballast water per hour.
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. This ensures effectiveness in challenging water conditions, but saves on power during normal running, the company said.
Designed to comply with the latest IMO and US Coast Guard regulations, the system is currently on the USCG ‘pending list’ for Type Approval.
Evac will also be installing Evac Optima 5 vacuum toilets on the ship connected to two online vacuum generation units resulting in significant savings in water usage throughout the life of the vessel.
On board black and grey water requirements will be covered by an Evac EcoScreen pre-treatment plant and an Evac MBR membrane bioreactor wastewater treatment plant. The MBR plant is certified to meet the most stringent standards of effluent water, nutrient and phosphorous removal. Grease separators for treating galley grey water will also be installed.
The contract also involves providing a marine growth prevention system for the cruise ship, which will eliminate blockages in seawater cooling lines caused by the growth of barnacles and mussels. Installations involve fitting copper and aluminium anodes in the sea chests, which are connected to a control panel.
The copper ions are carried through the pipework system and prevent larvae from settling or growing, whilst the aluminium ions create an anti-corrosive layer on the inside of pipes.
In addition, Evac is supplying a fully integrated system for processing dry and wet waste from the ship’s galley. The new vessel 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, General Manager of Evac Norway, who led the sales and technical team involved in the contract.
