Should maritime regulators prioritize operational flexibility for ships over strict ballast water compliance standards?
BIMCO, along with the Republic of Korea, the Marshall Islands, and INTERTANKO, has submitted a proposal to the International Maritime Organization to revise ballast water management guidance. The move aims to address operational challenges faced by ship crews in poor water quality conditions.
Why it matters
Operators face recurring issues with treatment systems that struggle in challenging water, leading to increased crew workloads and procedural uncertainty. This proposal seeks to formalize contingency measures that were previously sidelined.
The proposal represents feedback from a 2025 survey covering 3,200 ships. It seeks to replace or amend the current Resolution MEPC.387(81) to address system bypass difficulties.
The players
BIMCO
BIMCO is the world's largest international shipping association, representing shipowners and operators across the global maritime industry.
INTERTANKO
INTERTANKO is an industry association that provides a forum for independent tanker owners to promote safe and environmentally sound transportation.
International Maritime Organization
The International Maritime Organization is the United Nations specialized agency responsible for the safety and security of shipping and the prevention of marine pollution.
The details
The submission includes a consolidated package of procedures, such as a pre-arrival assessment flow chart, to guide crews when treatment systems encounter water quality limits. These revisions intend to clarify management protocols and decontamination procedures after a system bypass occurs.
Timeline
BIMCO conducted a ballast water management survey throughout 2025.
The Marine Environment Protection Committee will convene for its 85th session at the end of November 2026.
Market Landscape
This effort marks a continued attempt to update Resolution MEPC.387(81) following the failure to gain support at MEPC 84. It highlights a push for standardized contingency procedures in a global regulatory environment that remains split on how to handle treatment system limitations.
For shipping operators, this proposal aims to provide clear, standardized protocols for managing treatment system failures during transit. Implementing these procedures would help crews navigate complex environmental regulations and reduce the operational uncertainty of shipboard water management.
The takeaway
The maritime industry is working to bridge the gap between regulatory requirements and the reality of water treatment system limitations. Standardized procedures for pre-arrival assessments could provide operators with much-needed clarity when dealing with water quality challenges.
What happens next
The Marine Environment Protection Committee is scheduled to decide on the proposed ballast water revisions during its 85th session occurring at the end of November 2026.
