O'Loughlin was unable to shake off several injuries this season, but he did manage to prove his fitness in the Grand Final win over Warrington Wolves.
Instead of pushing for a spot in the England squad for the Four Nations, O'Loughlin enjoyed a short break before returning to pre-season training with the Warriors.
After a disappointing Four Nations campaign, England will be looking to prove a point ahead of the World Cup in Australia.
Although he will be 34, O'Loughlin believes he still has a role to play if he can prove his fitness.
He told Wigan Today: "I had a couple of niggles I needed to get right. I had one or two small things, which built up. I was grateful to get back for the final but it was obviously not great prep.
"It was hard to watch without being a part of it. We just needed to get to the final, and not doing it left a disappointing taste in the mouth. But there are bigger things next year and hopefully we can crack on and improve.
"I hope to (be a part of it). Hopefully if I’m fit and healthy I can be a part of the World Cup. If they want me I will put my hand up."
