Tidetech to present âBeyond Weather Routing: the role of next generation oceanographic data', at Green Shiptech China Congress 2013. The presentation will highlight the role of integrated, high-resolution oceanographic data in improving vessel efficiency and reducing bunkerage through route and speed optimisation. It will also focus applications in performance monitoring, improved ocean current forecasts, and new regional data models for Singapore/Malacca Straits, the China Sea and other Asian shipping routes. Tidetech managing director Penny Haire said oceanographic data for shipping efficiency was a new and low-capital approach to reducing bunkerage and emissions that could be applied immediately to new and existing ships.
