Garryowen led 14-3 at the interval with Stephen Crosbie landing a penalty for the visitors.
Garryowen dominated a lively second half which produced four tries, two to either side.
O'Mahony got a brace for Garryowen to complete his hat-trick and fullback Danny Riordan and Jonathan Slattery crossed for Belvo.
Jamie Gavin kicked a total of fourteen points, four conversions and two penalties.
Stephen Crosbie converted one of the Belvo tries and he also kicked a penalty.

Shannon 13, Dolphin 31

The many times champions got to within four points of the visitors sixteen minutes into the second half thanks to a try by James Loxton to leave it 17-13 for Dolphin. The winger made a great break down
the left to touch down but that was as good as it got for Shannon.
