This educational museum is built on the retired Ocean Star Off Shore Drilling Rig. The rig is a “jack up rig” that is towed to its location with a mat underneath the rig and its three support columns retracted.
When it arrives on location, the mat is dropped to the ocean floor and the columns are extended until they reach the floor too. The rig is jacked up so it is 25 feet above sea level. Then it is ready for drilling. When drilling is complete, it is towed to another site to repeat the process. Different rigs are required to drill and to pump the oil, if discovered.
The museum has many interesting exhibits including a large scale model of the sea floor with the various types of rigs (the “jack–up” is only one of four or five types of rigs). The types of rigs differ mostly with the depth of water they are drilling in.
Specialty equipment includes a hyperbaric chamber for decompression used by the divers ----
and an escape pod used if the men must evacuate the rig quickly.
The pod can hold up to 26 people. That is one ride you would not want to take with 25 other people!
Other mechanical equipment exhibited was the drill head drive mechanism
and the oil distribution “Christmas Tree”. Invented in 1972, the Tree consists of a series of hydraulic valves that distribute oil and other fluids to and from the well head at the sea floor.
And of course, we cannot forget the drill tower ----
Add to these the exhibits a full size crane, a helicopter, and an array of drilling bits, as well as a short movie and a number of interactive exhibits, and you will experience what we considered an interesting and informative afternoon about the complexities of oil exploration on the high seas.
