OceanSaver Mark II BWTS

OceanSaver has won a contract from Greek oil tanker operator Almi Tankers to deliver a ballast water treatment system (BWTS) for two very large crude carriers (VLCCs) being built at South Korea’s Daewoo Shipbuilding & Marine Engineering (DSME).

Scheduled to be delivered in July 2013 and November 2014, the 320,000dwt vessels are being built to ABS class and will be equipped with a 2 x 3000m3/h type approved Mark II OceanSaver system.

Mark II OceanSaver system results in a pressure drop of less than 0.7bar, features a back-flushing filter with 40 micron screens.

The energy requirement for Mark II and related equipment is 50% less compared to its Mark I while it does not require any additional treatment at de-ballasting operations.

The vessels are designed to exceed high environmental standards, reflecting client demand for clean & green operation.

According to the company, the first system will be commissioned this year and include its second generation design engineered for reliability, low maintenance requirements and low power consumption.

Currently, Almi manages two Aframax LR2 vessels and three newly-built suezmax crude oil carriers and by this November it expects to take delivery of seven more Suezmaxes and two VLCCs.

In April this year, the company won a contract from Oshima Shipbuilding to deliver BWTS for four open hatch bulk carriers being built for Gearbulk at their Japanese shipyard.

Oshima said that each of the 72,000dwt vessel, which will be fitted with a 1,200m³/h type approved Mark II OceanSaver system, are being built to DNV class.

Based on OceanSaver’s second generation design, the first two systems will be installed this year and are expected to require less maintenance and burn less power.

Disinfection is achieved through the on-board generation of oxidants delivered to the ballast flow via side stream injection from OceanSaver’s C2E sea water activation module.
