The weather forecast by satellite data is a good guideline for assessment of voyage planning route in order to have safe and economic voyage for shipping. ISO15016, "Guidelines for the assessment of speed and performance by analysis of speed trial data", has been developed by the working group ISO/TC 8/SC 9/WG 2. This paper presents the effects of wave speed & direction, wind speed and direction, current speed and direction, and depth of water in vessel voyage planning which is based on

The interpolation between satellite data, historical chart data and observed data can optimize voyage route and cause reduction in sea passage time and fuel oil consumption. Various analysis methods for resistance increase due to ship motion, wave diffraction, wind, steering, drifting, water temperature, salt content, deviation of displacement, hull and propeller surface roughness and shallow water effects are considered in this paper and could be contained in computer program. INTRODUCTION The objective of weather forecast by satellite is to assist the navigators to improve ships voyage planning and optimize fuel consumption. It could simply be said that a computer program enable us to calculate the increase resistences on ship's hull for navigators. It could be given immediately by selection of route, speed and environmental conditions effect on fuel consumption with interpolation of data. This is the aim to improve the ships performance by means of optimizing the vessel voyage planning and way of proceeding for the voyage. This system is being utilised in airline industry since early 80's airplanes have used the system based on a similar idea by knowing the planes performance and fuel consumption in different speeds, weather conditions and jet streams in upper atmosphere and finally, the presumed time of arrival they generate a voyage plan with speed profile for keeping up with the schedule and taking the benefit from known winds and streames.
