BIMCO has moved a step closer to finishing a global set of guidelines needed to protect the marine environment from invasive species and reduce CO2 emissions.
Jotun has developed a proactive cleaning solution, using robotic technology. The solution also includes a special antifouling coating.
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.
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.
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. It also ratified others regarding unlawful acts against the safety of navigation and removing wrecks from the seabed. In addition, it signed four instruments covering liability and compensation.
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.
Identifying organisms and microbes in ballast water, as well as monitoring port marine life where ballast water may be released, are key for countries preparing to enforce IMO’s Ballast Water Management Convention. A workshop in Batumi, Georgia, from 3 to 5 July provided participants from nine countries with theoretical and practical training in compliance, monitoring and enforcement of the Convention.
During his presentation at the last GREEN4SEA Conference, Dr. Ioannis Arabatzis, CEO, Nanophos, attempted to clarify the misty landscape of underwater marine coatings, for non-chemists. He namely presented contemporary chemical technologies in the market, in a simplified, understandable way and formulated the checkpoints for a successful selection of a hull coating system.
A team of chemistry researchers from the University of Sydney Nano Institute has created nanostructured surface coatings that have anti-fouling properties without using any toxic components. The new coating uses ‘nanowrinkles’ which are inspired by the carnivorous Nepenthespitcher plant.
GAC Egypt announced that expanded its HullWiper hull cleaning system to vessels berthing at ports in the Suez Canal. The eco-friendly remotely operated vehicle has already attended its first vessel, respectively a crude oil tanker.
