ACO Marine completes the installation and commissioning of a Clarimar MF-10 wastewater treatment plant
ACO Marine has completed the installation and commissioning of a Clarimar MF-10 wastewater treatment plant supplied to Damen Verolme Rotterdam for installation to the Stena operated semi-submersible Stena Don. The drilling rig’s existing wastewater treatment plant was heavily corroded and non-compliant with regulation MEPC 227(64), which entered into force in January 2016. It was replaced with the biological-type Clarimar MF-10 black and grey water treatment unit as part of an extensive four-month refit.
Once the equipment has been unpacked and in-situ, assembly is simple. Since ACO Marine’s Clarimar units are manufactured from the ACO Group’s proprietary Composite PPFR, no hot welding is required. Unlike coated steel, the Polymer PPFR material is lightweight and completely resistant to corrosion, abrasion and chemical attack and the tank material is guaranteed for life against corrosion. The plates and other elements of the assembly are fused together by simply “ironing” a bead of polymer along the joints. Once assembled the tank is then pressure tested and bolted in position to the vessel’s structure.
In this particular installation ACO Marine’s installation team, working closely with both the yard and the owner’s team, identified a solution where the discharge pump and blower assemblies were located on the other side of a separating bulkhead with an access opening for the removal of the ACO-MF Bio Sword filtration technology. The ACO Bio Sword eliminates the requirement for settling and chlorination stages.
The Stena Don project marked the second in a series of Clarimar MF units ACO Marine has supplied as flat-packs. The experience gained from the 2016 installation of an almost identical solution to the DSV Bibby Polaris helped in reducing installation and assembly times considerably.
