The present invention relates to a drape hose which is typically utilized in offshore drilling facilities. Torsion resistance in the drape hoses is improved to by including a wedge shaped piece of material at the top of a gooseneck element in addition to the conventional series of pins. With further refinements, the wedge element could replace the need for pins or keys on the connection.
The present invention relates generally to mechanical elements of an offshore facility, and more particularly to a drape hose used in such offshore facilities.
Normally, offshore facilities utilize drape hoses which provide hydraulic pressure to various functions in an offshore facility. Such offshore drape hoses which provide hydraulic pressure in various functions are typically attached to a marine drilling riser via certain fabricated structures typically called ‘goosenecks’. Generally, a drilling riser is a conduit that provides a temporary extension of, for example, a subsea oil well to a surface drilling facility. The purpose of the gooseneck is that it is required to retain hydraulic pressure and any loading from the drape hoses which may include torsion loads.
The torsional forces which occur are conventionally resisted by utilizing a pin or a series of pins. However the pins have been known to fail on various occasions creating a potentially hazardous situation.
It would be desirable to have a more effective means to resist the torsional and other loads in offshore drape hoses.
