ABSTRACT:
A crane or derrick for use on an offshore platform comprising a base, a boom operatively connected to the base, and a sectioned kingpole secured to said base, the kingpole including a first kingpole section secured to the base and at least one additional kingpole section removably secured to the first kingpole section. The sectioned kingpole permits the installation of a crane having a tall kingpole and thereby greater lifting capacity such that equipment necessary to carry out operations such as the driving of conductor pipe and piling can be erected on the deck of the platform without the necessity for utilizing a derrick barge.
