A flowline jumper for providing fluid communication between first and second spaced apart subsea structures includes a length of conduit having a predetermined size and shape and first and second connectors deployed on opposing ends of the conduit. The first and second connectors are configured to couple with corresponding connectors on the subsea structures. At least one electronic sensor is deployed on the conduit. The sensor is configured to measure at least one of a vibration and a load in the conduit.

Load and vibration monitoring on a flowline jumper

A vertical multi-bore jumper. The jumper is outfitted with interfaces that include rotatable hubs accommodating perimeter bore terminations that may be rotated about a central production bore. In this manner, the multiple bores may be flexibly aligned with corresponding couplers at equipment located on the seabed. As a result, undue torque is not placed on the jumper in attempting to align multiple bores at the interfaces which may be frequently misaligned at the outset of such installations.

Multi-bore jumper interface

A subsea connector assembly with flowmeter incorporated therein. The assembly is particularly configured for securing a flexible flowline at subsea production managing hardware such as at a manifold at a seabed or Christmas tree at a well head. Incorporating a flowmeter into the connector as opposed to such comparatively larger scale hardware ultimately saves substantial material, transport, installation, footspace and other costs.

Subsea flowmeter connector assembly

A gasket capable of sealing against multiple sealing surfaces, comprising an inner seal ring for sealing against inner sealing surfaces, an outer seal ring for sealing against outer sealing surfaces, one or more intermediate seal rings for sealing against one or more intermediate sealing surfaces, and a connector member for connecting the inner seal ring, one or more intermediate seal rings and the outer seal ring. In some embodiments, the gasket includes a retaining feature for securing the gasket in place and a removal feature for removing the gasket. In some embodiments, the various components of the gasket (e.g., seal rings, connector members, retaining feature, etc.) are composed of different materials (e.g., metal, metal alloy, plastic, rubber, ceramic and/or glass).

Gasket with multiple seal rings

A subsea flowline jumper connector includes at least one electronic connector deployed thereon. The sensor may provide data indicative of the connector state during installation and production operations.

Instrumented subsea flowline jumper connector

A technique for engaging a bore connector with a receptacle on subsea equipment. The technique may include providing an operator with a visual indication of acceptable alignment between the connector and the receptacle in advance of attaining engagement. In this way, a proper and reliably sealed engagement may be achieved. Further, the bore connector and techniques for use thereof include added indication of completed sealed engagement sufficient for testing and/or operational use of the connector in supporting a fluid application directed at the equipment through the receptacle.

Bore connector engagement technique

A technique facilitates clamping operations by providing mechanical advantage. According to an embodiment, a clamping system comprises a clamp having a plurality of clamp segments with surfaces oriented to securely hold and clamp mating features, e.g. mating hubs, of adjacent components. The clamping system also may comprise an actuator coupled to the clamp to enable selective shifting of the clamp between an open position to receive the mating features and a closed position in which the clamp segments are contracted together to secure engagement of those features. A driver is coupled to the actuator to enable movement, e.g. shifting, of the actuator when opening or closing the clamp. The actuator facilitates operation of the driver via, for example, an ROV by providing mechanical advantage and thus increasing the clamping force applied by the clamp to the mating features.
