Marine Systems Inc. (MSI) has delivered a pair of modular ballast water treatment units specially designed for tank barge and ship operations and developed in concert with Glosten and Alfa Laval.

According to Glosten, the units were developed in response to requests from vessel operators, and MSI enlisted the Seattle-based naval architecture and marine engineering consultancy to develop the design. Alfa Laval provided PureBallast 3.1 treatment systems, Filtrex high efficiency filters, and extensive installation experience.

Each ballast module has a treatment capacity of 1,000 m3/hr within a 20’ shipping container footprint. Built at the Foss Seattle Shipyard complete with lighting, ventilation, and integrated controls, the modules are are ABS and U.S. Coast Guard approved for hazardous area installations and shipped ready to plug-and-play.

Designed for efficiency, the modules are intended to reduced technical demands on busy shipyards by eliminating the need to juggle the independent components and vendors required for a traditional ballast water treatment system installation. Each purchased module is fully tested prior to shipment, and includes integration support from MSI and Glosten engineers.

“The demands of the vessel operator drove this design,” said Kevin Reynolds, principal at Glosten. “Doing this as a manufactured product ensures that we get it right, every time.”
