Abstract
An arrangement for handling a power cable of an offshore, wind turbine for transportation and/or connecting to a switch gear and/or reconnecting, the arrangement including: a cable support system adapted to support a portion of the power cable; a guiding system being fixedly connectable or connected to a wind turbine tower and being adapted to guide the cable support system along a linear, vertical, track is provided.
Claims17
An arrangement for handling a power cable of a wind turbine, the arrangement comprising:
- a cable support system configured to support a portion of the power cable;
- a guiding system being fixedly connectable or connected to a wind turbine tower and being configured to guide the cable support system along a linear track;
- and
- a platform floor, connectable or connected to the wind turbine tower;
- wherein the guiding system is fixedly connected to the platform floor, traversing the platform floor, such that a first portion of the guiding system is arranged above the platform floor and a second portion of the guiding system is arranged below the platform floor;
- and
- wherein the platform floor comprises a closable through opening in the platform floor configured to allow the cable support system to be moved through the opening, the cable support system being guidable through the opening such that:
- in a normal operational state, after installation and connection to a switch gear, the cable support system does not protrude from the platform floor surface upwards, but is arranged entirely below the platform floor, such that an end of the power cable protrudes beyond a lower end of the wind turbine tower, and/or
- in a transport operational state, the cable support system entirely or at least partly protrudes from the platform floor surface upwards, such that an end of the power cable does not protrude beyond the lower end of the wind turbine tower.
A method of handling a power cable of a wind turbine, for transportation and/or connecting to a switch gear and/or reconnecting, the method comprising:
- supporting a portion of the power cable by a cable support system configured to be guided along a linear track by a guiding system fixedly connected to a platform floor and traversing the platform floor such that a first portion of the guiding system is arranged above the platform floor and a second portion of the guiding system is arranged below the platform floor, wherein the platform floor comprises a closable through opening configured to allow the cable support system to be moved through the opening;
- and
- lifting and/or lowering the portion of the power cable by guiding the cable support system together with the supported cable,
- wherein in a normal operational state, after installation and connection to a switch gear, the cable support system does not protrude from the platform floor surface upwards, but is arranged entirely below the platform floor, such that an end of the power cable protrudes beyond a lower end of the wind turbine tower, and/or
- wherein in a transport operational state, the cable support system entirely or at least partly protrudes from the platform floor surface upwards, such that an end of the power cable does not protrude beyond the lower end of the wind turbine tower.
