Drilling Duty vs. Production Installations

The Seatrax marine offshore crane product line consists of a wide range of standard crane structures that can be equipped with several types of standard machinery packages. The crane structure size is determined from the lifting capacity/radius requirements. The machinery packages are determined by the intended service on the offshore installation.

The following pictorial displays the machinery arrangement differences between structurally identical cranes configured either for typical fixed platform support or drilling duty and floating installations...more.

Seatrax Drilling Duty vs. Typical Production Duty Cranes

Seatrax has primarily built deepwater drilling cranes for many years. In the deepwater drilling environment, the cranes typically run 24/7 under extreme dynamic conditions.

Drilling crane owners and operators are most concerned with costly crane maintenance and safety. The primary reason for these concerns are the shortcomings of the typical platform crane, being modified and adapted for the drilling environment. These shortcomings include rotation bearing and mounting bolt maintenance and failures, very small winches requiring periodic replacement or tear-down for inspection, inadequate winch breaking, anti-two blocking, wire rope maintenance, and the overall corrosion resistance of the structure and equipment...more.
