Monopile foundation and method for installation of a monopile foundation

An installation method for a monopile foundation in a bottom of a water basin, comprising:

• placing the monopile foundation at an installation station, placed vertically and stabilized in position,
• bringing the monopile foundation into contact with the bottom of the water basin,
• driving the monopile foundation into the bottom of the basin, wherein the placing and bringing of the monopile foundation are executed using a surrounding clamp,
• before placing the monopile foundation vertically in a bottom area, attaching the surrounding clamp and an attachment to a connection flange of the monopile foundation and placing the monopile foundation vertically,
• once the monopile foundation is placed vertically, closing a geopositioning device on a circumference of the monopole foundation and submerging the monopile foundation in the water basin, and then driving the monopile foundation into the bottom of the basin, wherein during the submerging and driving, air and water with sediments are discharged outside the monopile foundation through outlet openings located below a bottom panel of a membrane,
• once the monopile foundation is driven under gravity, releasing the clamp and removing the attachment,
• installing at a top of the monopile foundation a driving device for the monopile foundation in the bottom of the basin and driving the monopile foundation mechanically to a target location,
• removing the clamp while the monopile foundation is weighed down, wherein a dry area is defined above the bottom inside the monopile foundation, and working infrastructure is provided above the membrane, and
• installing an intermediate part on the connection flange at the top of the monopile foundation and installing a working device on said part while the area above the bottom inside the monopile foundation above the membrane is filled with an inert gas.
