Biofouling: U.S. Contact List
According to the International Maritime Organization, harmful aquatic organisms are a major threat to world oceans. Biofouling, described as the accumulation of microorganisms on ships’ hulls, is considered one of the main vectors for biological invasions.
Introduction
Excessive biofouling can cause ecological harm (Ruiz et al., 2000) as well as excess emissions due to drag. With the former, destruction of local environments due introduction of non-native species is estimated to cost $1.5 to $3 billion dollars a year in the U.S. (Archana et al., 2019). With the latter, a vessel may experience a loss of as much as 15% loss of shaft horsepower (Molland et al., 2014) which contributes measurably to shipping’s “2.7% of [total] global anthropogenic carbon dioxide (CO2) emissions” (Bakka et al., 2022).
Techniques to mitigate biofouling in commercial shipping include application of anti-fouling paint and manual removal of microorganisms, usually during shipyard.
Source Documents
The primary document that addresses biofouling in global shipping is the International Maritime Organization’s Resolution MEPC.378(80) adopted July 7th, 2023. The document includes guidelines for management of biofouling on ships. The document is free and can be found on the IMO website.
A secondary document is the IMO’s publication Guidelines for the control and management of ships’ biofouling to minimize the transfer of invasive aquatic species published in 2024. The cost to purchase this publication is around USD $120.
Within California, where I reside, biofouling requirements can be located under the California Code of Regulations Title 2, Section 2298.1 et seq. Having been through this process personally, I would strongly suggest working closely with your ship agent and a California State Lands agent well ahead of arrival.
Biofouling Removal Providers
The IMO maintains a list of U.S.-based biofouling removal providers within their Global Integrated Shipping Information System (GISIS).
The list of United States based providers (IMO, 2024) with accompanying contact information is as follows:
Conclusion
A biofouling record book “should be provided to every ship with a Biofouling Management Plan (BFMP), to record relevant biofouling activities such as inspections, maintenance and cleaning activities” (IMO, 2024).
Parameters for addressing biofouling removal can be found in MEPC 80/17/Add.1 Annex 17, page 47 through 52. A primary indicator is slip, or the difference between the distance a ship actually travels and the distance it should travel based on the propellor pitch and number of revolutions.
Further, within a charter party, there may be a biofouling clause. BIMCO maintains a current biofouling clause with notes and commentary on their website.
