The disclosure relates to a template for introducing at least one helical pile into the ground, in particular a seabed. The template comprises a base comprising a helical pile guiding device and at least one foot. The at least one foot may extend laterally away from the helical pile guiding device in at least one lateral direction. The at least one foot has a lower surface configured to rest on the seabed. The at least one helical pile guiding device is configured to guide a helical pile into the ground from an initial pile position to a target depth. The helical pile guiding device comprises - a lower passage, located at a lower end of the initial pile position and configured to allow a helical pile to pass; - at least one guiding member extending upwardly from the base; a pile connector connected to the at least one upwardly oriented guiding member and configured to be connected to a helical pile. The template is provided with one or more drives for rotating the helical pile and driving the helical pile into the seabed. The lower surface of the at least one foot may counteract the torque applied to the helical pile when driving the helical pile into the seabed. The template may be provided with one or more foundation pile guides for guiding a monopile during installation thereof.
