Narrative:
The approach to runway xx was stabilized and on the calculated ref speed. Upon touching down the touchdown markers of runway xx at ZZZZ airport and rolling out; in the deceleration phase of landing we encountered significant standing water on the surface of the runway which caused the aircraft to hydroplane. This took away any ability that I had to positively control the airplane. The aircraft then shifted to right and unavoidably departed the side of the runway. As the aircraft came to a stop; it came in contact with the outlying fence.
