Abstract
A lock means for one end of a tension line for securing said tension line to a subsea installation and particularly for securing one end of an umbilical line carrying hydraulical and electrical control circuits to a subsea installation. A lock means cooperable with a guide and locking cylindrical member secured to the subsea installation, the cylindrical member having a lock dog receiving recess, and a cylindrical locking device receivable within the cylindrical member and secured to the end of the tension line. The locking device includes a cylindrical housing having a lock dog port and a cylindrical chamber, an elongated annular or sleeve-like piston member within the housing and longitudinally slidable relative to the tension line. The piston member includes a cam surface to slidably engage lock dogs for lateral movement thereof through the lock dog port into locking engagement with the lock recess, a piston portion cooperable with a cylindrical chamber for unlocking said device under fluid pressure, and a piston extension having an upper end exposed through a window for mechanically unlocking the locking device. The piston member is normally biased into locked position by spring means, the locking device being normally nonreleasing.
