System, method and apparatus for subsea installation of buoyancy modules

摘要

Systems, methods and apparatuses for the installation or removal of buoyancy modules onto or from a submerged conduit are described herein. A system may include a buoyancy module (30), a control panel (76), an actuating means (72), and a clamp tool (40). The buoyancy module may include at least two sections. The clamp tool may hold the sections of the buoyancy module. The clamp tool (40) may include at least two plates (50, 52, 54, 56) that are actuated opened or closed, using the control panel (76) and/or the actuating means (72) during attachment or removal of the buoyancy module (30) to the submerged conduit (10).

主权项

1. A tool for subsea installation of a buoyancy module onto a submerged conduit, the tool comprising:
a first plate pivotably coupled to a second plate; a third plate pivotably coupled to a fourth plate; a first telescoping member extending between the first plate and the third plate; a second telescoping member extending between the second plate and the fourth plate; a first ram operatively coupled to one of the first telescoping member, the second telescoping member, or a combination thereof; a second ram operatively coupled to one of the first plate, the second plate, the third plate, the fourth plate, or a combination thereof; a buoyancy module; and a fastener that removeably secures the buoyancy module to one of the first plate, the second plate, the third plate, the fourth plate or a combination thereof; wherein the first, second, third and fourth plates have portions defining a cavity, and wherein the cavity is dimensioned as to surround a submerged conduit.
