AWT Insights: A Fleet Operations Briefing
In this Issue
Skip Vaccarello As consumers of products and services we all want to get good value for the money we spend. AWT takes our value proposition very seriously. In this month’s AWT Insights, you will have the opportunity to see examples of the value AWT delivers to its customers.

Wojdylak describes how AWT improves the Global Numerical Weather Prediction model to come up with more accurate, realistic forecasts and wave models. With better forecasts and models, our shore-based Route Analysts can recommend safer and more fuel and time efficient voyages for our customers. In addition, ship masters can rely on accurate, realistic forecasts in planning their own routes using AWT’s on-board voyage optimization software, BVS.
We welcome your feedback.
Thank you,

Weather Model Enhancement
by Herm Wojdylak
Herm Wojdylak
  Herm Wojdylak
Global Numerical Weather Prediction (NWP) models are the foundation for weather forecasting, especially in the medium and long range period required for optimum ship routing. On a global scale, the model output is quite representative of the prevailing weather patterns, but raw NWP model data can be misleading since each global model has its strengths weaknesses in handling certain weather situations. For this reason, AWT modifies the raw ‘gridded’ model data to better reflect what is likely to happen before the data are used in ship routing or provided to customers as gridded weather data, images, or text forecasts.
AWT Wind/PressureOne weather phenomenon that is generally poorly handled by global models is the tropical cyclone. Model analyses and forecasts for tropical cyclones often depict the systems as much weaker than they actually are, and the model's predicted track and speed of movement are frequently quite poor. To ensure accuracy, AWT uses the warnings issued by agencies specializing in forecasting tropical systems, such the National Hurricane Center (NHC), Joint Typhoon Warning Center (JTWC), Japan Meteorological Agency (JMA), etc.

Weather Routing Return on Investment
Consistent Value in an Uncertain Market

by John Eaton
It is widely known within the shipping industry that using weather routing services to assist vessels along voyages can save time and fuel. The overall perception of value derived from ship routing, however, has largely been viewed as ambiguous, anecdotal, and even unproven to some. John Eaton

In an effort to change this perception, AWT has taken a proactive approach to analyzing the routing services provided throughout the year by providing detailed return on investment reports. This is done Weather Routingby using a unique database of seasonal baseline routes and comparing them against AWT’s recommendation or Masters intended route to produce a transparent summary of time, bunkers and greenhouse gas emission savings. These reports, presented to many large and prominent shipping companies on a monthly and quarterly basis, serve as frequent reminder to the remarkable value AWT provides. Savings are displayed in bottom line figures that ship operators can use and integrate directly into their overall fleet management.
