Device for suspending a tubular from a floating vessel
First Claim
1. A device for suspending a tubular from a floating vessel, the device comprising:
- a first element configured to carry the tubular;
a second element configured to be supported by the floating vessel; and
at least one compression element which forms a connection between the first element and the second element,wherein,the at least one compression element is configured to be pre-tensioned in an end stroke position so that, when the at least one compression element is subjected to a force from the tubular which is below a pre-defined threshold force, the connection formed by the at least one compression element between the first element and the second element is always a rigid connection, andwhen the at least one compression element is subject to a force from the tubular which is higher than the pre-defined threshold force, the connection formed by the at least one compression element between the first element and the second element is a compressible connection.

Abstract
A device for suspending a tubular from a floating vessel includes a first element which carries the tubular, a second element supported by the floating vessel, and a compression element which forms a connection between the first element and the second element. The compression element is pre-tensioned in an end stroke position so that, when the compression element is subjected to a force from the tubular which is below a pre-defined threshold force, the connection formed by the compression element between the first and second element is a rigid connection, and, when the compression element is subject to a force from the tubular which is higher than the pre-defined threshold force, the connection formed by the compression element between the first and second element is a compressible connection.
