Hi Gkrane - My name is Pete and I manage the Dive Team at Seaventures. I'll answer your questions below:
The rig used to be a working oil rig. It originally operated in Panama before being decommissioned and moved to Singapore. It has been a dive resort since the late 1990's. It still has most of its original features but has been cnverted into a resort [for example the old heli-deck is now a sun deck]. Life on the rig is awesome....! But i'm biased! Have a look at our Tripadvisor reviews for a more independent view. The food is superb, accommodation comfortable [but probably not luxurious], service exemplary, and we offer unlimited diving on our house reef. In answer to your question, this, and a Turtle cleaning station, is just below the rig and you access it via a lift.
We offer three daily boat dives in the Mabul/Kapalai area [great for macro] and a daily boat/3+ dives to Sipadan - where you generally see the larger schools of Jackfish, Barracuda, Bumphead Parrot Fish, Sharks and Turtles. In fact, the BBC are coming next week to film some sequences for an upcoming nature documentary. In order guarantee a visit to Sipadan [all operators have a daily quota] you would need to book one of our four day/three night packages.
I hope that answers your questions. Please don't hesitate to contact me directly -
pete@seaventuresdive.com - if i can help some more.
Have a great day
Pete
