Watch: Tackling invasive aquatic species
A new IMO video animation shows how aquatic organisms can build up on surfaces and structures exposed to the sea – a process known as biofouling.

Key points of the IMO PPR 7 outcome
Highlights of the PPR 7 included the finalization of the guidelines for scrubbers, development of a basis for work to determine the impact of scrubber water discharge, draft regulations for prohibiting the use and carriage of HFO as fuel in the Arctic, and revision of guidance on ballast water system commissioning.
BIMCO issues biofouling survey results to IMO
To better understand how shipowners view the biofouling and in-water processes, BIMCO launched a survey in 2018, highlighting that manual collection of data is the most popular method among the companies that responded; The results of the survey were presented to the IMO.
Study shows antifouling and fouling coatings improve vessel’s speed and performance
PPG in collaboration with DNV GL launched a study which concluded to the fact that vessels that use their fouling release and antifouling coatings present enhanced speed and power performance. The results of the study were presented at the 4th annual Hull Performance and Insight Conference (HullPIC) in Gubbio, Italy.
Indonesia and Mexico join IMO’s GloFouling project
According to the IMO, marine biodiversity is in danger of invasive aquatic species (IAS), which harm the world’s freshwater, coastal and marine’s native ecosystems, a challenge that led to the launch of GloFouling Partnerships project; Thus, taking part in the project, Indonesia and Mexico have formed their national task force.
Recreational vessels increase biofouling in Med. Sea
Researchers from the Italian University of Pavia, conducted the first research in the Mediterranean combining boat and marina sampling data to better understand how private boats spread alien species, resulting to marine pollution.
Do you know why ships are red on bottom?
Chances are you have never salvaged a vessel yourself or you have (hopefully) never seen a vessel upside down. But in case you have seen photos of a shipwreck or of a new ship getting launched from shipyard, you may have noticed that the bottom of a ship is most times red.
Peru becomes the latest country to accede to anti-fouling treaty
IMO informed that Peru has now acceded to an important IMO treaty helping to protect the marine environment. Namely, the Control of Harmful Anti-fouling Systems on Ships Convention. The treaty prohibits the use of harmful organotins in anti-fouling paints and sets out a mechanism to prevent the potential future use of other harmful substances in anti-fouling systems.
Non-lethal hard fouling able to prevent barnacles from attaching to the hull
During a 40-month trial of an antifouling coating containing an anti-barnacle active agent, barnacles failed to anchor themselves to the tanker’s hull. The technology activated the barnacle larvae’s octopamine receptor, keeping them in swimming mode and preventing them from attaching to the hull with non-fatal effect.
IMO’s GloFouling project on marine biodiversity launched
The five-year GloFouling Partnerships project, a collaboration between GEF, the UNDP and IMO, kicked off at a global workshop at IMO Headquarters in London, UK, in an event on 18-20 March. The project seeks to address bioinvasions by organisms which can build up on ships’ hulls and other marine structures.
