ACO Marine commissions wastewater plants

ACO Marine has successfully completed the commissioning of wastewater treatment units aboard the Sveti Krševan, Supertar and Cres operated by Croatian owner Jadrolinija.
The three 87.6-meter vessels were each retrofitted with a Clarimar MF-2 biological-type sewage treatment plant at the Dalmont shipyard in Kraljevica, Croatia, the oldest continuously operating shipyard in the world, with a history dating back to 1729.
Italy’s La Fornitrice, ACO Marine’s engineering partner in the region, completed the commissioning of the system aboard Cres, the final ship in the series, in May. Equipment for all three retrofits was delivered to the yard between December 2018 and January 2019.
“Jadrolinija is a long-standing customer of La Fornitrice so we were delighted to have won the national tender for supplying the ACO Marine system to these vessels,” Robert Devetak, Managing Director, La Fornitrice, said. “The project is a good reference for La Fornitrice in that the contract includes after sales servicing of the Clarimar units.”
The contract also included the supply of detailed installation drawings to the shipyard and the issuance of the requisite approval certificates from the Croatian Ship Register (HRB).
Prior to the installation and commissioning of the Clarimar units, the 600-passenger capacity ferries did not treat wastewater streams but instead collected the effluent in holding tanks. In the busy summer months, this meant that the tanks needed emptying on a daily basis.
“The storage of a vessel’s wastewater streams in onboard holding tanks is not the most operationally-efficient solution,” Mark Beavis, Managing Director, ACO Marine said. “The use of port reception facilities can be costly and also delay ship turn-around-times.”
While performance and cost-efficiencies were key factors in the owner opting for the ACO Marine solution, the decision to retrofit a wastewater treatment unit, however, was a decision led by regulatory necessity.
Until recently, Croatia did not have strict or detailed regulations governing the discharge of wastewater into its coastal waters. However, in 2015 Croatian authorities completed the Coastal City Pollution Control Project, putting an end to indiscriminate discharging practices, and mandating solutions for treating and monitoring wastewater discharges.
“We anticipate a run of orders from Croatia-based ship operators as they look to retrofit wastewater treatment systems to meet the new requirements,” said Beavis.
