Definitions
- the present invention relates to a device for supporting a riser from a floating vessel comprising a drill floor with an opening through which a riser extends suspended in a gimbal.
- a riser may be regarded as an extension of a well extending from the seabed up to a floating vessel.
- the riser is assembled by successive individual pipes being connected on the vessel. As new pipes have to be connected the assembled pipe string is suspended from the vessel.
- a collar or wedges are normally employed which are mounted in the rotary table on the drill floor and keep the already mounted riser string in position while a new pipe is retrieved from a pipe store and connected to the pipe string. The riser string is then raised slightly to enable the wedges to be released and then lowered, whereupon the wedges again secure the riser when so desired.
- the intermediate, flexible and annular element may form a complete ring, while in another embodiment it may be designed so that it can be divided in at least one point, thereby facilitating installation and dismantling.
- the element may be provided with a substantially uniform cross section on the internal cavity viewed in a direction along the circumference of the element.
- the element may be provided with a varying cross section in a direction along a circumference, thereby forming at regular or irregular intervals chambers, which have a larger cross section than the connections between the chambers.
- control means for example in the form of valves, may be inserted in the connections between the chambers.
- One of these valves may be of such a type that it can be dismantled in order to provide an opening in the annular element for mounting and dismantling thereof.
- the device may also comprise devices for deactivating the freedom of relative movement between the two frame parts.
- a possible variant of such a deactivating device may comprise a locking device which locks the two frame parts together, thereby preventing relative movement between the parts.
- Another possible variant of the devices will be to have arrangements which enable the fluid inside the flexible element to be withdrawn, thereby preventing the possibility of achieving relative movement between the frame parts. In such a case these arrangements must also comprise devices for refilling the annular element.
- the device according to the invention may include locking means thereby enabling the gimbal to be locked, i.e. the riser 10 is locked to the drill floor 5 thereby achieving transfer of forces between the drill floor and the riser and they are also kept at rest relative to each other. This may be necessary, for example, in cases where a job has to be done in connection with the top of the riser 10.
- the locking means may be locking pins as illustrated in fig. 3 which can be moved between an open position (right side of fig. 3) and a locked position (left side of fig. 3). The gimbal can thereby be locked in an inactive position.
