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.

During the last 40 months an MR tanker has been in active operation across a wide range of trade routes globally, often sailing in global biofouling hotspots with > 25oC (up to...

Guyana ratifies treaties for safe and clean shipping

Guyana has signed up to a host of IMO treaties supporting safe, secure and clean international shipping. The treaties cover a wide range of topics including marine pollution, dumping waste at sea and responding to pollution incidents involving hazardous and noxious substances.

Specifically, Guyana ratified two key IMO measures aimed to preserve bio-diversity: the Ballast Water Management Convention and another on use of harmful anti-fouling systems on ships hulls.

Understanding marine biofouling: How anti-fouling systems prevent growth

During a ship’s lifetime microorganisms, plants, algae, or animals will gather in its hull, during a process called biofouling. These organisms, known as invasive aquatic species, can negatively affect a ship’s operation, while they also present a threat to the marine environment. However, there is a solution and is called antifouling. Antifouling is the process of protecting a ship’s hull with specifically designed materials, such as special paints, that prevent these organisms from piling up...
