SPOS in Focus: Weather Elements and Seakeeping (video)

Accuracy is essential when dealing with something as unpredictable as the weather. Tomorrow’s forecast is 99% likely to be accurate; up to five days ahead, accuracy is in the 90%+ range. But after five days it drops to 80%, and after nine days it drops to 60% accuracy.

 

For weather routing, this means that if you use the starting data for a twenty-day voyage, after nine days, it’s not likely to be accurate enough. Therefore, recalculating every day pushes the nine days forward and gives shipping companies a better picture of what will occur in the short term.

 

Here are two essential features in SPOS, the onboard weather routing system, which ensures shipping companies have the most up-to-date weather data and can apply this information to keep both crew and cargo safe.

 

Weather Elements

 

When it comes to weather elements, SPOS includes most of the parameters that you’ll need: including wind at 10m or 50m, swell, wind waves, risks per element, ocean currents combined with tidal currents, salinity, etc.

 

Use SPOS to overlook 20+ extended weather elements, choice of resolutions, display options along your whole voyage. This range of options covers all that a voyage could require, with both standard and extended sets of weather elements, choice of resolutions, and display options.

 

Metocean conditions affect all phases of a passage, so reliable and accurate forecasts are essential. This data helps address the main concerns that come with working in shipping: managing costs, keeping voyages on track, and ensuring the crew and assets are safe.

 

For companies working in shipping, MeteoGroup offers a nautical specific model: Nautical MeteoBase (NMB). It is the critical forecast data engine that feeds all marine-related products used by the industry. NMB draws on various sources of atmospheric and oceanographic model forecast data to deliver accurate weather forecasts.

 

In SPOS, the weather forecast input receives forecasts up to four times a day via e-mail or HTTP download. It contains more than 20 elements for voyage optimization, using the MeteoGroup Nautical MeteoBase.

 

Seakeeping module

 

Rolling resonance and high waves can have a devastating impact on a ship and its cargo. Protect motion-sensitive ships and cargoes by optimizing your route calculations according to provided weather forecasts, specific characteristics of the ship and motion limits, with the SPOS Seakeeping module:

 

In the SPOS Seakeeping module, you can visualize the IMO Resonances along the route, such as parametric and synchronous roll, broaching, and high waves. You can also set thresholds for any ship movement: the angel of motions, the accelerations, the vertical or horizontal movements, for seasickness, and more.

 

The routing advice in the Seakeeping module is tailored to individual vessels (hull shape and dimensions) and therefore offers an optimized voyage performance that is unique for each ship. It forecasts ship responses and resonances along any route. It gives captains the tools to optimize their vessel route to evaluate escape options in both direction and speed quickly.

 

Optimize your route for your thresholds, either by showing warnings or by avoiding accidents of thresholds. Display the motion attention and risk zones on the map play, through time. See all motions on the voyage info for each point on the calculated route and import the actual loading conditions to have the exact inputs for the vessel motion forecast.
