Weather Forecast Warrants Cleaner Environment

Out there in the vast expanses of the sea, the seamen give their best to keep the ships at the best of conditions. One of the factors that aids their efforts is the weather forecast information.

With the help of the modern-day technologies, weather predictions can be done well in advance – as early as 15 days – before the ship actually takes course for the route. In addition to this, the accuracy levels have improved so much so that attributing a mark of 90 or 95 per cent to it, wouldn’t raise a finger.

Widely known is the fact that knowing about weather conditions in advance helps a ship plan, re-plan her routes, saving time and ensuring better safety. Less known is this that it also helps protect the environment. Yes, weather forecast aids ships cause less harm to the environmental.

The ships run on fuel. Every time there is a tide or rough weather, the ships take longer hours for the same route. Even the low RPM contributes to it. Prior information on how high is the tide or how much is the sea wave going to swell saves time and fuel.

The captain steers the ship into a different direction altogether or regulates the RPM as per the requisites, based on the weather reports. This, what we do not realize, is saving so much. Along with time and fuel, it leads to a reduction in costs, saves fuel and most importantly it also means a much lower level of CO2 emissions.

According to the recent statistical reports of the shipping industry, the number stands at more than 50,000. On January 2018, there were 53,045 ships in the world's merchant fleets and counting. This volume suggests that even an ounce of difference per ship will take the total to bring about a big difference and this is exactly what is happening.

Some amount of CO2 that would otherwise be termed as negligible is making a huge difference because when the negligible(s) of more than 50,000 ships come together, the impact is huge.

Knowledge on upcoming weather gives space to the vessel to improve their sustainability and reduce environmental impact. Today, the world has awaken to stop emissions as much a s possible. In the shipping industry, if the rough sea predictions are shared with the seamen at the right time, weather routing is done and this saves up to four per cent on overall expenses.

However, the biggest drop can be realised by reducing the speed of the vessel. Reduced speed can decrease the CO2 emissions by around 30 per cent or more. Technology is transforming our restricted thoughts about it. The potentials are widening with every passing day.
