Ulster started their Pro12 campaign with a bonus-point win over Ospreys at the Kingspan Stadium on Friday.
The hosts had the physical edge, epitomised by rampaging centre Stuart McCloskey who claimed a try alongside Rob Herring and Wiehahn Herbst.
Luke Marshall sealed a good night's work in the final minute, rounding off a flowing move for Ulster's fourth try to secure the extra point.
Ospreys rarely threatened the line and relied on Sam Davies' boot for points.
Both sides were missing players on World Cup duty, Ulster eight and their Welsh visitors 12, but there was no lack of experience on either side.
Ospreys gave a debut to Wales back-row Gareth Delve, the former Bath, Gloucester and Melbourne Rebels forward playing his first game for a Welsh regional team.
But he was able to make little impact as Ulster dominated, with Ospreys' cause not helped by the sin-binning of back-row Joe Bearman midway through the second half.
Ospreys 'got what they deserved'
"It was pretty disappointing… we got what we deserved which was nothing out of the game," Ospreys coach Steve Tandy said.
"I'll have to look at [Bearman's sin-binning] again but some of these decisions are fine lines and in slo-mo they look worse than what they are.
"We've been well beaten tonight and we'll have to refocus, but the next game comes around pretty quickly [at home to Munster on 13 September] so we've got to lick our wounds and come back fighting as Ospreys do."
