Underwater Cleaning for Professional Shipping

Since 2018 a project consortium composed of representatives of the Environment Department of Bremen, of the ports management company bremenports, of the Coast Guard of Lower Saxony, of the Federal Agency of Shipping, of raw material suppliers for paint companies, of the Polar Institute Bremerhaven, of the shipping company Laeisz, of diving and cleaning companies, of the University of Applied Sciences Bremerhaven, and LimnoMar performs a research project on underwater cleaning of ship hulls. The project focuses on three topics:

Demonstration of practicability and efficacy of underwater cleaning of ships hulls coated with non-toxic, abrasion resistant coatings

Demonstration of collection and filtration techniques/systems for the removed fouling organisms with respect to water quality and introduction of invasive species

Drafting of application requirements for permissions of underwater hull cleaning and propeller polishing

There are a couple of documents introducing the project, participating vessels, treated coatings, and legislative aspects.

Application and Permission Requirements

An essential task of the project was the drafting of basic requirements for permissions to clean vessels hull. Application forms and standards were reviewed and compiled, mainly based on those used in Malta and South Africa. Conditions, standards and a proposal for an application form were drafted and can be downloaded.
