摘要： An actuatable sealing mechanism for sealing a fluid channel provided between two co-axially arranged tubular members having a central longitudinal axis. The actuatable sealing mechanism comprises an elastomeric seal, an axially moveable actuating sleeve member (1400; 2400; 3020) and a radially moveable activating member. The activating member is configured to be moveable in a radial direction in use to translate the actuatable sealing mechanism between an unsealed state and a sealed state. When it is in the sealed state, the activating member axially compresses the elastomeric seal sufficiently to expand the elastomeric seal in the said radial direction to seal the fluid channel.

摘要： The integration joint assembly includes an integration joint body (10) having a through bore (16), the body being for connection with a riser system. The integration joint assembly permits a tubular work string (50; 54) to pass there through such that there is an annulus created between the inner through bore (16) of the integration joint body (10) and the outer surface of the tubular work string (50; 54). The integration joint body (10) can also include at least two (300, 200) and more preferably three sealing devices (300, 200, 100) within its through bore (16). A method of drilling is also described as including the steps of installing an integration joint assembly in a riser string and running a tubular work string (50; 54) through the through bore (16) thereof.

摘要： A subsea rotating control device (RCD) system (1; 2) adapted to permit a tubular work string to pass there through such that there is an annulus created between the inner throughbore of subsea rotating control device (RCD) system (1; 2) and the outer surface of the tubular work string.
The subsea rotating control device (RCD) system (1; 2) comprises a system housing (10) comprising a throughbore, an upper end and a lower end (10L) adapted for connection with a BOP (18) of a wellhead.
The subsea RCD system (1; 2) further comprises at least two RCD seals (302, 2302; 304, 2304) arranged for selective mounting within the system housing (10) and which are selectively actuable between an unsealed configuration and a sealed configuration.-
