BUDDY CANTILEVER SYSTEM FOR JACK UP RIGS FOR USE WITH SELF ELEVATING DRILLING RIGS (OIL amp; GAS INDUSTRY)

摘要

This invention is centered on assisting, enhancing and improving the conventional cantilever design such that it can result in higher load carrying capacity. Such an adaptation utilizes the invention that has superior, novel and innovative features. By using this invention, it immediately improves load carrying capacity of cantilever in the drill area and thus the derrick hook load can be maximized at extreme corners of the drill area circumscribed by the combination of movement of drill floor and cantilever. The invention is based on an add-on concept applicable to existing cantilevers or new installations. It is portable in design and can be shared among a fleet of drilling rigs of similar cantilever design The invention is made up of simple structural components that can be adapted to existing rigs or built in new rigs. The "buddy" beam can be made in sections for ease of handling and installation. The invention does not involve complicated moving systems, hydraulic or electrical. Needless to mention, the maintenance aspect is also simple and easily manageable. Overall cost to include the invention in existing or new rigs to achieve the higher load requirements is highly justifiable.
