Coldharbour Marine Scoops Innovation Award


Linby based Coldharbour Marine Ltd, manufacturers of technical equipment for maritime customers, have won a prestigious Innovation Award.  The award, announced on 16th April 2015 during the annual Marine Propulsion Conference in London, recognised the innovative approach Coldharbour Marine took to solving problems associated with shipping large volumes of ballast water around the world.


Ballast water has been used to keep ships balanced for over 100 years but ecologists discovered that the carriage of ballast water from one part of the world to another meant that varieties of marine organism and bacteria were also being transported, leading to risks to human health and the disruption of sensitive marine ecosystems by alien aquatic species.  These range from epidemics of Cholera in human populations; outbreaks of red-green algae which clog previously clean waterways and the explosive growth of zebra muscles transferred and then released into previously clean environments.


The problem has been identified as one of the top three threats to the world’s oceans and in 2004 the United Nations International Maritime Organization took action to address the situation.


Worldwide, over $30 billion will have to be spent on ballast water management systems (BWMS) over the next decade. More than 57,000 vessels will require a BWMS with capital costs ranging from $175,000 to $490,000 for smaller ships to between $650,000 to  $3 million for larger tankers.


Over 5 years Coldharbour Marine researched the needs of tanker owners before developing a patented system to treat large volumes of ballast water whilst tankers journey between ports. The volume of ballast water needed together with the physical size and energy demands of BWMS means that tanker operators face particular hurdles that operators of smaller vessels may not have to worry about.

Speaking on behalf of Coldharbour Marine, Chief Executive, Andrew Marshall said, “ This award is a testament to 5 years of thought, debate, problem solving and testing- frankly a recognition of the engineering excellence of the Coldharbour team.  The introduction of the IMO Ballast Water Management Regulations encouraged us to start a major recruitment drive. We are expanding our business in the East Midlands and attracting expert engineers and scientists to our team. Our attitude to innovation has not stopped and we have other exciting projects in the pipeline. I hope this award is the first of many.”
