The M/V Celebes Explorer is the only liveaboard dive boat operating in the Semporna Marine Park, an area off the east coast of Sabah, East Malaysia, that includes the world famous Sipadan Island.

During the southwest monsoon that blows between May and October, the conditions on the Andaman coast become inhospitable for liveaboard diving and some boats redeploy to the Gulf of Thailand side which has an inverse weather pattern.
