Minerva Marine has selected Wartsila’s ballast water management systems (BWMS) in a bid to ensure compliance with ballast water treatment requirements.

The agreement covers the retrofit of “several vessels” and was described by Wartsila as “an important milestone” in the BWMS retrofit market.

The Andreas Martinos-backed shipowner manages a fleet of VLCC, suezmax, aframax and MR tankers as well as capesize bulkers.

The main BWMS chosen for the tankers is the Aquarius ATEX compliant Electro Chlorintation EX, which uses a two-stage process involving both filtration and electro-chlorination (EC).
