Two 115,000 dwt Aframax crude oil tankers are to be fitted with ballast water management systems supplied by Evoqua Water Technologies. In a statement today (14 March), the manufacturer said that the order has come from a South Korean yard for vessels under construction for a Singapore-based shipowner. BWTT believes them to be a pair of tankers ordered last September by Eastern Pacific Shipping at the Hanjin Subic yard in the Philippines, which are scheduled for delivery in 2018.
Each vessel will be fitted with a 3,000 m3/h capacity SeaCure BWMS and a significant factor in securing the contract was its ability to treat the vessels’ aft peak tank without needing an additional electrochlorination unit, according to Evoqua’s global business development director for ballast water, Lars Nupnau. “Rather than taking a full flow or in-line approach to ballast water treatment, the small-feed stream process is particularly advantageous to the tanker segment as just one system can treat all ballast water tanks,” he explained in today’s statement.
“Because the electrochlorination part of our system is installed in the engineroom we can use the same electrochlorination unit. For the shipowner, this means lower capital expenditure and a less complex, time-consuming installation.”
JaeWook Bae, team manager of the BWMS business at Krosys, Evoqua’s Korea-based partner that secured the order, explained that the side stream that will feed the electrochlorination part of the system will be from the sea chest in the engineroom when the ship is in marine water, and from the aft peak tank when in brackish or fresh water.
Evoqua will deliver the units in the middle of this year during the vessels’ early construction phase. Evoqua’s statement quoted Matt Granitto, its business manager for ballast water treatment, who said that the contract means that “we now have tanker references on newbuilds and existing tonnage.”
