Abstract: A device (10) for monitoring strain of an elongate member (12) is deployed underwater. The device (10) comprises a first clamp (14) configured to embrace and couple to the elongate member (12) at a first axial location, a second clamp (16) configured to embrace and couple to the elongate member at a second axial location separated from the first axial location, and a sensor which is responsive to an angle between the first clamp and the second clamp.

Abstract: The invention relates to a roller (10) which is to be mounted upon a conduit (12) to be deployed on the seabed. The roller facilitates lateral movement of the conduit. It is able to rotate relative to the conduit when mounted. The roller has an outer face (36) which contacts and rolls upon the seabed in use. The outer face is shaped to provide treads (38).

Abstract: The invention relates to a protection assembly for mounting in an underwater support structure, and to a method of installing such an assembly. According to one aspect of the invention, the protection assembly comprises at least one bend protection device (20a, 20b) coupled to a retaining device (18). The bend protection device (20a, 20b, 26) and the retaining device (18) together provide a through-going passage (32) for receiving an elongate member which is to be protected. The support structure (12) has an opening (16) through which the elongate member is passed, and the retaining device (18) is configured to be received in the opening (16) in the support structure and to engage with the support structure to resist subsequent withdrawal from it. Installation of the protection assembly comprises grasping an end portion of the protection assembly with a releasable clamp (100), arranging a pulling line to pass through the opening in the support structure to the mechanical clamp and securing the pulling line to the mechanical clamp (100), drawing the retaining device of the protection assembly into the opening (16) in the support structure using the pulling line and engaging the retaining device with the support structure, and releasing the clamp (100) from the protection assembly.

CPC classification number: E21B17/017 , E21B19/004 , E21B43/0107
Abstract: The invention concerns a bend stiffener (50) for locally protecting an elongate flexible member (60) from excessive curvature under bending loads. The bend stiffener comprises an elongate stiffener body (52) which comprises polymer material and which has a root end (54) and a free end (56). A passage (58) extends through the stiffener body from the root end to the free end for receiving and embracing the flexible member. A coupling (66) is provided at or toward the root end of the stiffener body for mounting the stiffener body in cantilever fashion. The stiffener body is sufficiently flexible to curve somewhat along with the flexible member when the flexible member suffers a bending load but is sufficiently stiff to resist excessive curvature which could otherwise damage the flexible member, and sufficiently resilient to recover its original shape upon relief of the bending load. The stiffener body comprises at least two stiffener body parts (64a, 64b) which together define the passage and which are able to be separated from one another to enable the flexible member to be introduced to the passage, and subsequently assembled to one another around the elongate flexible member to ready the bend stiffener for use. Each of the stiffener body parts is provided with a respective interface member (68, 70) which comprises material which is stiffer than the polymer of the stiffener body. The bend stiffener further comprises a securing arrangement (80, 83) for securing the interface member of one stiffener body part to the interface member of another stiffener body part to secure the stiffener body parts to one another.

IPC: E21B17/01
Abstract: The invention relates to a buoyancy module (100, 200, 300, 400, 500, 700) which comprises multiple buoyancy elements (104, 204, 304, 404, 504, 604, 704) coupled to one another. Each of the buoyancy elements has a recess (110, 210) and the buoyancy elements are laterally juxtaposed with their recesses aligned with one another to encircle the elongate member in use. Multiple buoyancy elements are stacked one upon another along a direction which is axial with respect to the elongate member in use, to form a buoyancy module of a predetermined axial depth. The recesses of the buoyancy modules together form an axially extending passage through which the elongate member passes.

Abstract: A bend stiffener (50) includes an elongate stiffener body (52) having polymer material and two ends. A passage (58) extends through the stiffener body from end to end for receiving and embracing a flexible member (60). The stiffener body includes a coupling (66) for mounting the stiffener body in cantilever fashion. The stiffener body is sufficiently flexible to curve somewhat along with the flexible member under a bending load but is sufficiently stiff to resist excessive curvature which could damage the flexible member, and sufficiently resilient to recover its original shape afterwards. The stiffener body includes at least two stiffener body parts (64a, 64b) defining the passage. Each stiffener body part includes a respective interface member (68, 70) having material stiffer than the polymer material of the stiffener body. A securing arrangement (80, 83) secures the interface members of different stiffener body parts together around the elongate flexible member.
