Biofouling and ballast water

LITEHAUZ has worked with OEMs, shipowners and policy-makers during the development of the Ballast Water Management Convention for more than a decade. We are experts in compliance issues and exemptions, and we developed the Same Risk Area exemption concept useful for local shipping. LITEHAUZ is your one-stop-service point to meet your needs in critical decisions points within all aspects of ballast water management regulation.

The issue of invasive aquatic species in ballast water is now dealt with under the BWMC, but the battle is not over yet. IMO initiated in 2018 a review of the voluntary 2011 Biofouling Management Guidelines and over the coming years we will undoubtedly see more administrations asking ships for an updated Biofouling Management Plan and a Record Book.

LITEHAUZ has taken part in the development and dissemination of biofouling management knowledge together with collaborators in the first mover countries of Australia and New Zealand. We are also independent experts in the performance software and the in-water hull cleaning methods.

Whether you are from the public or private sector, let LITEHAUZ be your partner to find the optimal solutions in terms of environmental impact, costs and administrative ease.
