LAIVrokote

LAIVrokote is a proprietary formulation developed by the Finnish company LAIVAT Oy, a subsidiary of Wärtsilä. It is a type of antifouling coating designed for marine applications, specifically for the hulls of vessels. The primary purpose of LAIVrokote is to prevent the accumulation of marine organisms such as barnacles, algae, and other biofouling on the submerged surfaces of ships.

This buildup of marine life, known as fouling, can significantly increase a ship's drag, leading to higher fuel consumption, reduced speed, and increased greenhouse gas emissions. LAIVrokote works by releasing biocides in a controlled manner to deter the settlement and growth of these organisms. The specific composition of the biocides and the release mechanism are key aspects of the coating's effectiveness and environmental profile, with efforts often focused on minimizing the impact on the surrounding marine ecosystem.

The application of LAIVrokote is typically carried out during scheduled dry-docking of vessels. It is applied as a paint-like substance to the hull, forming a protective layer. The durability and performance of the coating are crucial for maintaining operational efficiency and reducing maintenance costs associated with hull cleaning. LAIVrokote is one of several antifouling technologies available in the maritime industry, with ongoing research and development aimed at improving performance, environmental compatibility, and cost-effectiveness.
