A Mechanism on Parallel Processing to Numerical Weather Prediction for Weather Routing-II : Accuracy Evaluation and Performance Benchmark of the Sea Surface Wind Prediction

Abstract

Regarding the development of a land suppo 提 system fbr the weather routing to calculate the optimal route of the vesse1 ， which is required to use the high accuracy datasets of predicted ocean environments ． Howeve ら recent weather routing services are not possible Io fbrecast the environmental datasets by themselves and use limited datasets by fbrecast agencles with high・ cost in the limited sea area ． ［ nthis paper ， we show the fbrecast results of the surface wind velocity at a locai sea are 灸 which is based on our cluster system ， In addition ， we evaluate the fbrecast accuracy of the sur飴 ce wind velocity between the WRF (Weather Research and Forecasting) and 出 e GSM (Global Spec錠al Model)models ． FinalIy ， we meas 皿 e dle peak pe 面 mance of

Evaluation of ship performance in international maritime transportation using an onboard measurement system - in case of a bulk carrier in international voyages

“…The former method includes seakeeping, propulsion, and maneuvering theories, which have been extensively developed over the last decades (Ohkusu, 1996). Weather routing (optimal routing) is characteristic of the latter method, which is based on the fact that current ship operation significantly depends on intuition and experience (Yokoi et al, 2009(Yokoi et al, , 2010. The IMO restricts the CO 2 emission from ships based on the EEDI (Energy Efficiency Design Index) (IMO, 2009).…”

A Study on the Propulsion Performance in the Actual Sea by means of Full-scale Experiments

“…The effectiveness of the weather routing on the energy saving mainly depends on the accuracy of the weather forecast data and that of the propulsion performance prediction in the actual sea where the effect of wind and wave on ship's motion exists. The weather forecast technology has been improved year by year and an easier method to obtain the worldwide accurate weather forecast data has been proposed (Yokoi 2010). On the other hand, the propulsion performance in the actual sea is usually predicted using the Self Propulsion Factors obtained by model tests due to the small amount of full-scale experiment data in the actual sea (Sasaki 2009, Tsujimoto 2000.…”
