Problems jetting out jackup legs in GoM

07 December 2010 ** WE ARE PLEASED to POST THIS on BEHALF of a colleague in GoM **

The Spartan 151 has been unsuccessfully trying to pull legs for over two weeks now. They were able to get 1 leg free, but are still battling the others.( It is a 150 H class independent leg cantilever, with triangular truss type legs.) The rig is in the Breton sound area”¦

Apparently the jetting system is insufficient in this area, and they have a javeler pump excavating at the can. They are jetting at 18 BPM with two strings of drill pipe (One angled in from a liftboat). They have the starboard leg free, the port leg is stuck. The bow leg generally not much of a problem so said.

Water depth is 14 feet and penetration was 64´ on the port leg. The jet lines on the rig can handle a maximum of about 300 psi going through the can.

Any suggestions would be helpful!

Kind regards
