Greek marine technology firm buys US peer, adding to expansion drive

Erma First, an expanding Greek manufacturer of ballast water treatment systems (BWTS), has bought a niche US rival to expand its product range.

The purchase of oneTank is the third corporate acquisition by Erma First in three years and adds impetus to an expansion drive that saw the Greek company widen its footprint well beyond its original, core business.

In 2019, Erma First gobbled up Metis Cyberspace Technology, a Greek company that aggregates and monitors ship engine performance data in real time.
