The US Coast Guard recently published a letter to the Coast Guard-accepted independent laboratories (ILs), providing guidance for evaluating manufacturer-identified operational limitations during type approval testing of ballast water management systems (BWMS).
The US Coast Guard Marine Safety Center received its 18th application for type approval for the NK-O3 BlueBallast II Plus Ballast Water Management System, manufactured by NKBMS Co. Ltd. So far, Wärtsilä Water Systems, BIO-UV Group, Samsung Heavy Industries Co, Techcross, Optimarin, Alfa Laval, TeamTec Ocean Saver, Sunrui, Ecochlor and Erma First have won the USCG type approval.
Mr Anders Lindmark, Head of PureBallast, BU Marine Separation and Heat Transfer Equipment, Alfa Laval emphasizes on the importance of planning well before installation of a BWTS considering vessel’s needs. Mr. Lindmark advises operators to plan before and focus on sufficient skilled engineering expertise.
The International Convention for the Control and Management of Ships’ Ballast Water and Sediments, 2004 (BWM Convention), entered into force globally on 8 September 2017. In this infographic, IMO presents ways to comply with the BWM Convention.
ClassNK found that installation deadlines based on the Ballast Water Management Convention for many ships are highly concentrated in the year 2022. ClassNK added that difficulties are expected in the installation of BWMS if everyone around the world waits until 2022, so it recommends installing early.
Irish Ardmore Shipping has encountered a series of operational problems on the BWTS that were installed on ten of its vessels in newbuild shipyards. Now the company has ordered the Norwegian BWT manufacturer Optimarin to replace these with 36 new systems across 18 chemical and product tankers.
USCG issued a Final Rule eliminating the requirement for certain vessels that operate on voyages exclusively within a single Captain of the Port Zone to submit an Annual Ballast Water Summary Report for calendar year 2018. This rule will reduce administrative burden.
Ballast water is a traditional way to improve the stability, propulsion and manoeuvrability of a vessel. Nevertheless, it comes with some downsides which may be ecological as well as economical. So, what can be done to improve this? The answer may lies at removing ballast water systems altogether, adopting ballast free ships.
The USCG Marine Safety Center received its 17th application for type approval for the NK-O3 BlueBallast II Ballast Water Management System, manufactured by NKBMS. So far, Wärtsilä Water Systems, BIO-UV Group, Samsung Heavy Industries, Techcross, Optimarin, Alfa Laval, TeamTec Ocean Saver, Sunrui, Ecochlor and Erma First have USCG type approval.
Recently, there has been an increase in cases where vessels calling at California ports are issued deficiencies by inspectors from the State Lands Commission (SLC) for a failure to submit Ballast Water Management Reports (BWMR) for each port of call, according to an alert by ECM Maritime Services.
