Fixed routes, same location? Then an exemption might be a benefit for you.
The IMO Convention offers the potential (Regulation A-4) to gain an exemption from Regulation B-3 (ballast water management) and avoid having to install costly ballast water treatment systems. Exemption applications require detailed surveys and risk assessments of your operating environments and must be approved by the Port States affected and/or those possibly affected.
The Ballast Water Centre undertakes expert reviews, surveys, tidal modelling, risk assessments and provides advice for the exemption application process.
