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 directio...
The results showed that the microhardness and tensile strength of the heat-affected zone as the weakest welding zone in some samples reduced up to 30% compared to the base metal. On the other hand, a decrease in rotational speed, an increase in tool movement speed, and the number of welding passes cause grain refinement and improve mechanical properties. However, the effect of decreasing the ro...
Phase 5 of the evaluation of the speed camera program in Victoria builds on the localised effects of the program studied in Phase 3, which found casualty crash reductions in areas within lkm of a speed camera site during high alcohol hours for up to 2 weeks after issue of a speed camera Traffic Infringement Notice (TIN). Phase 5 had 2 main aims; (1) To investigate the localised effects of the s...
• Maximum speed in a seaway: 'involuntary' speed reduction due to added resistance in waves and 'voluntary' speed reduction to avoid excessive motions, loads etc. • Route optimization (routing) to minimize, e.g., transport time, fuel consumption, or total cost. • Structural design of the ship with respect to loads in seaways. • Habitation comfort and safety of people on board: motion sickness, ...
