Rotterdam study says just-in-time arrivals can result in big savings

SUBSTANTIAL fuel savings can made if sea-going vessels were better informed about the availability of berths and adapted their speed accordingly, says a study commissioned by the Port of Rotterdam Authority.
The study, conducted by Netherlands Organisation for Applied Scientific Research (TNO), said that during the last 12 hours of the ship's approach to the port it should know the precise moment a berth becomes available.
"That means reducing speed so they arrive just in time. This in turn leads to less fuel consumption and therefore lower emissions of carbon dioxide, sulphur oxides and nitrous oxides," said the port authority press release.
Significant savings are also possible thanks to shorter waiting times for ships in anchorage areas, it said.
The results of the study were presented this week at the head office of the International Maritime Organisation (IMO) in London during a meeting of the IMO Intersessional working group on the reduction of Greenhouse Gas emissions from ships.
"In percentage terms, we're talking about modest amounts,' said GloMEEP Project technical advisor Astrid Disport.
"But it's these types of measures that can make a huge difference in the short term and help reduce the carbon footprint of marine shipping," she said.
TNO and the port authority, which is a member of the Global Industry Alliance to support low carbon shipping, analysed movements of containerships sailing to Rotterdam in 2017.
"By supplying more accurate information to ships, four per cent - or 134,000 tonnes - of CO2 emissions can be saved every year," said TNO researcher Jan Hulskotte.
"To do this, containerships would have to adjust their sailing speed by five per cent, and still arrive at the planned arrival time." said Mr Hulskotte.
Earlier this year, the Port of Rotterdam Authority launched Pronto, an optimisation platform which combines data sources so that a port call by a vessel can be planned accurately.
"This way, activities that must take place during the port call can be seamlessly coordinated with each other. The study data was immediately converted into a view in Pronto that makes just-in-time sailing possible," said the press release.
Shipping companies can see what the sailing speed was, what the ideal speed would have been and how much fuel and CO2 could have been saved, it said.
