NOTES
1.) Port side is +, Starboard is -
2.) Tank %-filled is never lower than 5% or higher than 95%
3.) Tank 1 is at bow
4.) If capacity is 0, this tank is not present
5.) Reference point is at mid keel at the bow
6.) Transporter movements are assumed to be timeless
7.) A negative "barge-jetty" value means barge below jetty, a positive "barge-jetty" value means barge above jetty
8.) Overall time excludes pump set-up and handling time
9.) A minumum of one pump per used ballast tank is assumed
