Ballast Water News

With the final ballast water deadline fast approaching, UV-based water treatment specialist BIO-UV Group said it anticipates an increase in inspections as Port State Control (PSC) inspectors check machinery installations, crew competencies and Ballast Water Management (BWM) Plans.From September this year, all vessels subject to the BWM Convention must have installed a D-2 compliant ballast water treatment system capable of dealing with the maximum number of viable organisms allowed to be discharged.

BIO-UV Group has received an order from SIEM Ship Management to supply its BIO-SEA Ballast Water Treatment Systems for a trio of SIEM-managed car carriers. The order, for retrofit installation to the Siem Copernicus, Siem Curie and Siem Socrates, is the latest in a series of deliveries of BIO-SEA B-Series equipment for installation onboard around a dozen SIEM Ship Management reefer vessels since 2021.In this latest order, BIO-UV Group’s maritime division will provide B02 BIO-SEA BWTS units with a medium to high flow rate of 300-cu.m.

Techcross announced its filterless HYCHLOR 2.0 ballast water management system (BWMS) obtained type approval from the U.S. Coast Guard at the end of January 2024.Techcross' HYCHLOR 2.0 is an updated version of the company's  HYCHLOR 1.0 system, which received USCG type approval in 2020. Notably, the filter had been eliminated in the HYCHLOR 2.0 system.BMWS filters, which play a role in initially filtering out sediment in seawater, have been a source of many AS service issues due to clogging or maintenance troubles.While the absence of filters may raise concerns about disinfection capability…

The U.S. Environmental Protection Agency (EPA) is issuing a supplemental proposed rule to reduce the spread of invasive species though ballast water that occurs with normal operation of large marine vessels.Following public input on EPA’s 2020 proposed rule—including meetings with states, tribes and other stakeholders—the agency is now issuing a Supplemental Notice to share new data and control options raised by stakeholders. This supplemental proposal will bolster the development…

UV-based water treatment specialist BIO-UV Group has introduced what it says is arguably the smallest UV BWTS in the marketplace, targeted at meeting increased demand for ballast water treatment systems from operators of workboats, yachts, research ships, OSVs, and similar-sized vessels. The new BIO-SEA L01-0030 Mini – more compact than the company’s existing low-flow BIO-SEA L range – is a fully automated filtration + UV-based system designed to treat ballast water flow rates…

Next year marks a crucial milestone for the International Maritime Organization’s (IMO) Ballast Water Management (BWM) Convention, with all ships required to meet the D2 standard for ballast water management by 8 September 2024. D2 specifies the maximum number of viable organisms allowed to be discharged. In most cases, it requires the installation of a ballast water management system (BWMS) on board the vessel.2024 will be a pivotal moment for the ballast water market and while it is true that the retrofit market will diminish and leave behind only a small newbuild market…

The U.S. Environmental Protection Agency (EPA) has settled with two shipping companies over claims of violations of EPA’s Vessel General Permit issued under the Clean Water Act.Under the terms of the settlements, Swire Shipping Pte.

Freshwater ecosystems are threatened by a host of environmental stressors from human activities. Among the most insidious and impactful of these is invasion by non-native species.Over the past two centuries, established populations of nearly 190 non-native species of invertebrates, fishes, plants and microbes have been discovered in the Great Lakes basin. They were introduced through several sources and pathways including canals, pet release, bait bucket dumping, aquaculture escapes…

Finnish marine technology manufacturer Langh Tech Oy Ab announced its LanghBW ballast water management system has received US Coast Guard type approval, making it the first UV-based system in the world to receive the SUCG stamp for one-way treatment.The LanghBW system, which is based on fine filtration combined with UV treatment with innovative reactor design allowing easy maintenance and installation flexibility, successfully completing IMO type approval earlier this year.“We are proud to announce being the first maker to have one-way treatment also approved by USCG…

French firm GTT has developed a versatile LNG feeder & bunker vessel concept for worldwide operation without the use of ballast water.Every day, many ships carry on board a considerable quantity of seawater as ballast over the oceans. Technically, this is needed in empty or partially loaded conditions, in order to maintain seaworthiness, reach sufficient draft for propeller immersion, and avoid excessive bow slamming.Such ballasting requires investment for the onboard systems and leads to substantial operating costs.

De Nora Marine Technologies, LLC, said it has entered a formal service subcontracting agreement with Nakilat-Keppel Offshore & Marine (N-KOM), one of the largest shipyard and offshore repair facilities in the Middle East, located at Ras Laffan Industrial City, Qatar.The deal will expand service convenience for De Nora Ballast Water Management Systems (BWMS) installed on vessels trading in the Gulf region.
