More owners of large vessels are opting for UV BWTS

JANUARY 22, 2018 — Alfa Laval says that an increasing number of owners of tankers and other large vessels are choosing UV based ballast water treatment systems (BWTS) over electrochlorination based systems.

The agreement includes technical services, engineering, integration, commissioning, training, scheduled delivery and spare parts.

The GloEn-Patrol treatment system utilizes a filter to remove 50 micron or larger size organisms and medium-pressure UV lamps to disinfect smaller organisms.

GloEn-Patrol models treat from 50 to 6,000 cubic meters of ballast water per hour. They have IMO-type approval and certification from many classification societies including American Bureau of Shipping (ABS) and DNV GL, and U.S. Coast Guard Alternate Management Systems (USCG AMS) for non-hazardous areas such as engine rooms, and explosion proof models for installation in areas such as the main decks of articulated tug barges (ATBs) and tankers.  

“We found Panasia ballast water treatment systems to be a good operational and functional fit for our vessels, backed with a level of commitment and service we require,” said Bill Metcalf, Crowley vice president of strategic engineering. “Panasia and its management team is fully committed to our vessels’ safety and the environmental performance of our ballast water systems, and we are pleased to have them as our partner.”

Crowley says that DNV GL is completing the required tasks for the Panasia system to secure USCG type approval will provide its report by October, 2016.

DHI Group has been chosen for shipboard tests and Golden Bear Facilities has begun the work on the land-based tests, all under DNV GL’s guidance, and supervision to comply with the Environmental Technology Verification (ETV) Program.

USCG issues new policy letter on BWM compliance


Blank Rome says that vessel owners and operators may realize a cost savings by a delayed compliance date, which would allow time for the approval of U.S. Coast Guard type-approved ballast water treatment systems before other systems are installed.

The firm says that owners and/or operators should therefore review the compliance dates for their vessels and consider applying for an extension if they will face a hardship coming into compliance with the Coast Guard’s Ballast Water Management rule in light of the fact that there are no type-approved systems as yet or any practical alternatives.

Issued September 10, 2015, revised Policy Letter 13-01 gives updated guidance to vessel owners and operators on BWM methods and streamlines the application process for vessel owners and operators to obtain extended compliance dates for implementing BWM methods, principally the installation of treatment systems.

Notable updates, says Blank Rome, include removing the five-year limit on cumulative extensions, clarifying “batch” and supplemental applications, deleting the requirement to submit vessel Ballast Water Management Plans with extension requests, and allowing extensions to vessels that choose to install Alternate Management Systems (AMS) accepted by the Coast Guard.
The Coast Guard has also provided template application forms and recommendations regarding applying for extensions.
