Abstract: Torque tool (200) configured for making up and breaking out joints (1a, 1b) in a riser (100), the tool (200) comprising: a tool body (3) and a tool head (4), the tool head (4) having a socket (4?) configured to receive a head (14) of a bolt (2) and apply a torque on the bolt (2), a torque sensor (20) operable to measure the torque applied on the bolt (2), and a pre-tension sensor (21) operable to measure a pre-tension in the longitudinal extension of the bolt (2) when the bolt (2) is received in the tool head (4). There is also provided a method for pre-tensioning bolted riser joints (1a, 1b) comprising a plurality of bolts (2), a method of managing a plurality of bolts (2) for riser joints (1a, 1b), a method of managing a plurality of bolts (2) for riser joints (1a, 1b), and a riser connector (101).

Abstract: An attachment device for securing a buoyancy module to a riser, the attachment device comprising an annular collar which is split into at least two parts, and at least one flange part, which is separable from the collar and has a generally planar flange and a connecting formation by means of which the flange part may be releasably connected to the collar so that the flange extends radially outwardly relative to the collar.
