Standardized tractor tug commands for ship-assist work

摘要

Many mariners have asked if there is a standardized tractor command language in use around the world. Sadly, the answer is no. The authors have been attempting to standardize tractor commands as they conduct training of pilots in the use of tractors at marine simulators.rnFor this discussion we will use the term "tractor" generically to include all z-drive reverse tractors or azimuthing stern drives (ASDs), fin first tractors, Voith Schneiders or z-drive true tractors, etc.
