    Abstract: A riser for a subsea well comprises a first riser section that may be similar to conventional risers in design and material specifications. A second riser section comprises a passive fracture section that is specifically designed to shear or fracture under design conditions, such as extreme events (e.g., extreme weather or waves, loss of control of a rig or vessel, a rig or vessel moving from a desired position). The passive fracture section is designed to fracture first to prevent or minimize damage to other well equipment, such as at the seabed.

    Abstract: A support system (12; 12') for providing horizontal support to a riser (32) extending downward from a cantilever (18) along a well centre and into a body of water comprising a riser interface (48; 48') and a tether arrangement (50; 50'). The support system (12; 12') is configured to permit asymmetric placement of the riser interface (48; 48') relative to the cantilever (18).

    Abstract: A carrier vehicle carries an unmanned subsea vehicle along an elongate body from a topside location to a subsea location. The carrier vehicle comprises a support structure configured to carry the unmanned subsea vehicle, and a translation mechanism comprising gripper arms connected to the support structure for causing the carrier vehicle to translate along the elongate body using a hand¬ over-hand action. The carrier vehicle can carry the subsea vehicle through a region of turbulence, such as a splash zone. This removes the need for special launch equipment to be installed on the platform to use the subsea vehicle.

    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 method for inspecting a riser asset of a marine riser includes generating a first predictive degradation rate of a first potential flaw in the riser asset based on an engineering assessment. The method also includes receiving, from sensors, sensor data indicative of a first flaw corresponding with the first potential flaw. The method also includes generating a first actual degradation rate of the first flaw based on the sensor data. The method also includes determining a first remaining operating lifetime of the riser asset based on the first predictive degradation rate and the first actual degradation rate. The method also includes determining a first inspection frequency for the riser asset based on a first safety factor and the first remaining operating lifetime of the riser asset. The method also includes generating a first inspection timeline based on the first inspection frequency.
