Abstract
The present invention provides a method for installing a hydroelectric turbine at a deployment site on the seabed which involves lowering the turbine and associated base onto the seabed from a vessel using a number of lines, and once on the seabed using these lines to tether the vessel to the base/turbine while telemetry from the base/turbine is analyzed.
Claims12
A method of installing a base and a hydroelectric turbine onto the seabed, the method comprising the steps of:
- connecting the turbine to the base;
- securing the turbine and base to an underside of a deployment vessel;
- said method further comprising sequentially
- transporting the base and turbine to a deployment site with the deployment vessel;
- lowering the base onto the seabed from a position secured directly beneath the underside of the vessel;
- keeping the vessel tethered to the base;
- establishing the suitability of the installation;
- and
- disconnecting the vessel from the base.

- securing the turbine and base to an underside of a deployment vessel;
- said method further comprising sequentially
- transporting the base and turbine to a deployment site with the deployment vessel;
- lowering the base onto the seabed from the position secured directly beneath the underside of the vessel by means of a plurality of lowering lines fed from the deployment vessel;
- feeding slack into the plurality of lowering lines once the base is located on the seabed;
- keeping the vessel tethered to the base after the step of lowering the base onto the seabed;
- establishing the suitability of the installation of the base on the seabed;
- in the step of establishing the suitability of the installation, receiving telemetry from at least one of the base and turbine when on the seabed;
- and
- disconnecting the vessel from the base after the step of establishing the suitability of the installation.
