Reduced wave-making resistance of a vessel operating in a seaway based on time-dependent Kelvin wake wave generation

A system for reducing wave-making resistance of at least one follower vessel following at least one lead vessel operating in a seaway, the system comprising at least one electronic processor configured to:

• determine at least a direction and propagation speed of at least one first Kelvin wake transverse wave at the location where generated by the at least one lead vessel, wherein the at least one first Kelvin wake transverse wave is generated by the at least one lead vessel at a first time and propagates in the seaway until at least a second time subsequent to the first time;
• based at least upon the direction and propagation speed of the at least one first Kelvin wake transverse wave propagating in the seaway from the first time to the second time, determine one or more locations in at least one reduced wave-making resistance region at which to position the at least one follower vessel when the at least one follower vessel and the at least one first Kelvin wake transverse wave are at the second time, wherein the at least one reduced wave-making resistance region is a region in the seaway associated with the at least one first Kelvin wake transverse wave that, when occupied by the at least one follower vessel, reduces the wave-making resistance of the at least one follower vessel by providing destructive cancelation with the at least one first Kelvin wake transverse wave;
• and
• output information associated with the determined one or more locations at which to position the at least one follower vessel in the at least one reduced wave-making resistance region associated with the at least one first Kelvin wake transverse wave corresponding to the second time to thereby reduce the wave-making resistance of the at least one follower vessel when at the second time.
