The world 's largest container shipper Maersk plans to retrofit an undisclosed number of vessels with open - loop scrubbers that are hybrid ready , at a cost of $ 263 m . Maersk declared in May 2017 that "scrubbers will not be the way forward for our fleet" and it was not a long-term solution "to place such complex machinery" on its vessels. However , the firm , which has long been a sceptic of the technology , will mostly rely on low sulphur fuels to comply with IMO sulphur cap regulations . Additionally , MSC is reportedly spending $ 500 m to retrofit 86 of its own ships at $ 5.1 m per tanker , which would equate to half of Maersk 's 750-strong fleet being fitted with scrubbers , or around 15 % of its total .
