A handy and simple tool to determine in a minimum time what is really needed as tug assistance, is the Bollard Pull Calculator which calculates in an approximate way the total required tug power for ships in various conditions of wind and current. This tool can be loaded as an app on the smart phone.
I am not a computer savvy. My knowledge in programming and robotics and those sort of things is nil. I get lost in the sea of social media and easily entangle myself in the web. All I have done for the last 25 years or so is to pilot ships through the Panama Canal. However, during the last couple of years I have done my best to catch up with technology, since it has enhanced our possibilities and improved safety in our field. But still, I have to admit that I am way behind the new guys in this important issue.
