Abstract
Method of installing a foundation (1) having a toe (2) which is inserted into a soil (10) until a depth of the toe (2) reaches at least a minimum installation depth threshold (23). During insertion, fluid is jetted from a plurality of nozzles (7) provided at the toe (2) for directing fluid distally into the soil (10) ahead of the toe (2). The jetting of fluid from the plurality of nozzles (7) is controlled based on the depth of the toe (2), wherein the rate of jetting of fluid is reduced when the depth of the toe (2) reaches a stabilisation depth (22) ahead of the minimum installation depth threshold (23).
Claims10
A method of installing a foundation (1) for a wind turbine comprising:
- inserting the foundation (1) having a toe (2) into a soil (10) and measuring installation resistance, wherein the foundation (1) is inserted until a depth of the toe (2) reaches at least a minimum installation depth threshold (23), and until the installation resistance reaches at least a minimum installation resistance threshold (16);
- during insertion, jetting fluid from a plurality of nozzles (7) provided at the toe (2) for directing fluid distally into the soil (10) ahead of the toe (2);
- and
- controlling the jetting of fluid from the plurality of nozzles (7) based on the depth of the toe (2), wherein the rate of jetting of fluid is reduced when the depth of the toe (2) reaches a stabilisation depth (22) ahead of the minimum installation depth threshold.
