Ships that are moored in ports need energy but since only few ports and ships are equipped with alternative maritime power, ships generate their own power with auxiliary engines creating noise, writes Rob Witte, DGMR consultant.
Rob Witte: 'Ports gain a large income from moored ships. This includes port dues which are based on the Green Award Certificate or Environmental Ship Index. The Green Award is based on safety and environmental requirements.
If noise was added as a topic to such a Green Award system, ports could award less noisy ships with lower port dues. In this way ports could influence the ships coming to a port and ship owners can make profit by installing silencers.'
