发明名称 DEVICE FOR SUSPENDING A TUBULAR FROM A FLOATING VESSEL
摘要 The invention relates to a device for suspending a tubular (13) from a floating vessel, the device having at least one compression element (11) which is pre-tensioned in an end stroke position such that when subjected to a tubular force below a pre-defined threshold force, the at least one compression element forms a rigid hang-off for the tubular, and when subject to a force higher than the threshold force the device forms a compressible hang-off for the tubular.
