Abstract
A retrievable umbilical termination module (UTM) is provided for a power distribution system. The UTM includes a first wet-mate connector directly connectable to a subsea transformer module, and a second connector connectable to one or more offshore power-generating apparatus. The first and second connectors are electrically connected to one another. The UTM further comprises an integrated switchgear or disconnection switch that is adapted to selectively control the flow of power from the second connector to the first connector. A subsea power system comprising the UTM, as well as methods for installing and retrieving the UTM, are also provided.
Claims14
A retrievable umbilical termination module, comprising:
- a first connector directly connectable to a subsea transformer module, wherein the first connector is a wet-mate connector;
- and
- a second connector connectable to one or more offshore power-generating apparatuses,
- the first connector and the second connector being electrically connected to one another;
- and
- a switchgear, the switchgear configured to selectively control the flow of power from the second connector to the first connector.
A subsea power system comprising:
- a transformer module having a first side and a second side, the first side connectable to onshore components;
- and
- at least one UTM comprising:
- a first connector directly connectable to a subsea transformer module, wherein the first connector is a wet-mate connector;
- and
- a second connector connectable to one or more offshore power-generating apparatuses, the first connector and the second connector being electrically connected to one another, and
- a switchgear configured to selectively control the flow of power from the second connector to the first connector,
- wherein the first connector is connected to the second side of the transformer module.
A method for installing an umbilical termination module (UTM), the method comprising:
- connecting a first connector to one or more offshore power-generating apparatuses prior to subsea installation;
- installing the UTM subsea;
- and
- connecting a second connector to the second side of a subsea transformer module, wherein the second connector is a wet-mate connector.
A method for retrieving a subsea umbilical termination module (UTM), the method comprising:
- disconnecting a connector between a transformer module and the UTM, wherein the first connector is a wet-mate connector;
- retrieving the UTM to a surface vessel or platform;
- and
- disconnecting a second connector between the UTM and one or more offshore power-generating apparatuses.
