Workhouse type jack-up drilling rig is one of the mid-size ones designed by a foreign
company, with compact space and all functions for drill. In the process of its building and
at the request of the owner, the original design was modified, the original air cooling
system for generator was changed to water cooling one, and the capacity of sea water cooling
system and piping system were re-computed, which solved the problem of large volume water
demand for cooling system during the jacking trail. The required berthing tests were
completed and it was successfully delivered to the owner. Currently the workhouse type
jack-up drilling rig has been functioning stably in the service waters.
