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 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 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 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.

Dedicated, unmanned, subsea tools used for installation and inspection, maintenance, and repair (IMR) tasks that require lift and/or handling capacity beyond that of free-swimming ROV systems.

A submarine which is a nearly neutral buoyancy submarine that is manipulated from a mother ship by an umbilical.

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

Suction piles are a form of fixed platform anchor in the form of an open bottomed tube embedded in the sediment and sealed at the top while in use so that lifting forces generate a pressure diffential which holds the caisson down

A device that is made as a tool to be used for a subsea purpose.

A umbilical for use subsea or between a surface station (e.g. platform) and a subsea Installation.

Is an artefact intended to collect a heavy phase by making use of gravity.
