Quark Expeditions newbuild

An expedition ship under construction by Croatia’s Brodosplit shipyard for polar cruise specialist Quark Expeditions will be the first vessel to be installed with an Evac Complete Cleantech Solution that also includes a ballast water management system.

The Evac Evolution ballast water management system has been developed over a 10 year period by U.K. based Cathelco, which was acquired by Evac last year. The system supplied for the Quark Expeditions vessel will have the capacity to treat 75 cubic meters of ballast water per hour. Based on a combination of filtration and UV technology, it has a “feedback loop” that 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. Designed to comply with the latest IMO and U.S. Coast Guard regulations, the system is currently on the USCG “pending list” for Type Approval.
The new expedition ship. designed to carry up to 200 passengers, 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 Brodosplit’s parent DIV Group. “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.”

Over the last five years, during the development stage of the vessel, Evac has worked closely with LMG, one of Norway’s leading naval architects 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, managing director of LMG.

Solutions for management of other water streams

In additopn to the BWMS, Evac will 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. Onboard black and gray 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 aluminum anodes in the seachests 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 aluminum ions create an anti-corrosive layer on the inside of pipes.

Range of dry and wet waste management systems

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 centralized vacuum waste system.

The offered Evac Complete Cleantech Solutions supports Quark Expeditions in recycling waste and reducing the volume of waste onboard the vessel. The related solutions include a bailer for cardboard, a glass crusher and dry waste shredder.

“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 AS, who led the sales and technical team involved in the contract.
