That's actually why I was asking. I'm already booked with Seaventures, but they sent me this:
Regret to inform you that there is no shuttle bus schedule at Tawau airport, you can look for the private van transfer at Tawau airport, if they still got space, they are willing to send you to Semporna with extra charge around RM30 - RM50.00 per person per way. For accommodation at Semporna, there is quite a lot of new budget hotel there, you can look for it at agoda.com or booking.com
Which I interpret as I need to figure out how to get to/from Tawau to Semporna where I can get the boat transfer to the rig.

You should book with Seaventures and fly into Tawau. If you inform the Seaventures main office about your expected arrival time they will arrange airport pick-up and boat transportation from Semporna harbor to the oil rig. Easy peasy
You won't want to spend more time in Semporna than is absolutely necessary!
