Installed equipment used to provide structural support.

A wall used to maintain structural integrity, and provide separation.

An electrical connector capable of withstanding submersion to a specified depth.

A wear bushing that is run into and set in the wellhead or christmas tree to protect the inside wall against wear from the drill bit and drill pipe during drilling operations.

An electric cable intended for underwater installation

Also known as a logic plate, is a hydraulic stab plate where spare lines are routed to along with the production lines of the distribution system to provide reconfiguration contingency at strategic locations.

A control module that is used to control a subsea production system.

A 'fibre optic pod' for use in a Distributed Temperature Sensing (DTS) system.

An artefact where hydraulics, chemicals, electrical power and signals are distributed from the main umbilicals to different subsea systems.

An 'equipment class' that is a class whose members are used in conjunction with subsea or subaquatic installations and/or operations.

Flexible pipe, wholly or in part, resting on the seafloor or buried below the seafloor, and used in a static application.

A subsea fixed structure supporting a wellhead.

Assembly used to attach umbilicals to host structure.

Tools or devices that enable the installation and/or retrieval of a subsea casing hanger.

Subsea equipment class that contains classes of artefacts which are infrastructure equipment.

System that controls and monitors the deployment, the operation and the retrieval of subsea production equipment and is used during installation, workover, and intervention of a single subsea tree from a moored or dynamically positioned deepwater mobile offshore drilling unit (MODU) or multi-service vessel (MSV).

Subsea or subaquatic equipment class that contains classes of artefacts which are instrumentation equipment.

Device or remotely operated tool deployed by an intervention system to mate or interface with an intervention fixture.

An artefact for connecting a well or a manifold to a subsea flowline.

A frame that is a structural framework to provide strength and protection for a subsea manifold.

Subsea or subaquatic equipment class that contains classes of artefacts which are mechanical equipment.

A device intended to prevent excessive jacket penetration into the soil.

A pipeline crossing which is subsea and located above or below a specific object or geographic feature.

A topside unit providing electrical power and communications to the subsea control and monitoring equipment

The protection structure that covers the subsea equipment (template, manifold, trees, etc. ) to protect the equipment from third party damages as e.g. dropped objects, anchors or trawl equipment.
