Slowplaying Trips OOP, bad play or unlucky?

I have moved you're hand to the tournament hand discussion board, because this is a hand of a tournament and not a ring game.

I would most likely lead the flop against so many limpers with bottom set for value and protection. It's not to likely 1 of the villains has 2 pair+. AK and KK+ should raise pre-flop. Especially on a passive table. As played I would go for a healthy raise as well on the min bet of the UTG player.
It's a little bit weird that the UTG limper now min 3bet and the CO cold called. The UTG player is the only player that could play KK+ like this and I expect the CO has most likely a weak made hand or a draw he/she can't fold. Read less I would shove for 7,7k effective more as well, but the UTG players line is really suspicious.

Hi this was a full ring cash game

That makes it even more weird. Than I expect this was a play money table.
This can't be NL10k based on the way everyone is playing.
I moved it back.
