fleet savings of US$600 million a year. Such savings would dwarf any outlay for research and development made by the AP Møller-Maersk group. Meeting the requirements of an
increasingly climate and environment conscious world and the ever higher oil prices are driving owners to look at ways that they can reduce, costs and emissions. If new regulations are providing owners with significant environmental challenges rising fuel costs are also focussing their minds like never before. Old ideas married with new technology
and design will have an impact on the environmental footprint of the industry and Maersk’s attempts to develop the WAIP system into a commercially viable design for larger ships will benefit the industry and society as a whole, in the long term. NA
GSF research into scrubber technology
A new Green Ship of the Future (GSF) initiative will study technologies that will help the industry meet the International Maritime Organization’s (IMO) emission controls in Emission Control Areas (ECA).

manager at D/S Norden, said: ‘As owner and operator of vessels operating both inside and outside ECA waters, we are following the rules and regulations regarding the SOx limits closely. We find it very important to find the optimum solution for both our existing fleet and for future newbuildings, and we expect that participation in this project will give us a valuable insight in that respect.’ NA
