Description

    Background
  • The present invention relates to a marine growth removal system for cleaning an erected open ended pile prior to coupling the pile, by using grout, to a construction to be founded, like a windmill.
  • In case of installing a wind turbine, a delay of more than a few days between mono pile installation and grouting operations is not uncommon. The grouting operation has for its purpose to firmly couple the mono pile and the windmill possibly with a so called transition piece. This delay between mono pile installation and grouting operations can be costly as marine growth and other surface debris can often quickly appear on the mono pile surface. The surface cleanliness of the pile is critical for effective grouting and therefore all loose debris and marine growth needs to be removed quickly and effectively to prevent a poor coupling or any costly grout removal operation.
  • US2010180915 A1 relates to cleaning of subsea pipes in general. The invention described therein is directed to a skid for cleaning subsea conduits, such as strakes and fairings, and a method of cleaning subsea conduits. This invention may be utilized for the removal of marine growth from subsea conduits. The disclosed skid and method of cleaning subsea conduits leaves room for improvements.

  • The invention aims to provide a marine growth removal system for cleaning an erected open ended pile which marine growth removal system is more easy to handle and provides a faster cleaning of the pile surface.
  • Another object of the invention is to improve a marine growth removal system in that a problem associated with that system is at least partly solved.
  • Yet another object of the invention is to provide an alternative marine growth removal system.
  • According to a first aspect of the invention this is realized with a marine growth removal system for cleaning an erected open ended pile in accordance with claim 1, the system comprising;
    • an elongate inner frame member for extending in a pile interior,
    • an elongate outer frame member for extending along a pile exterior, wherein the outer frame member is coupled with the inner frame member and wherein the inner frame member and outer frame member are arranged with respect to each other such that a pile wall section accommodation space extends between the inner frame member and the outer frame member,

    The clamping system and the outer frame member and the inner frame member being moveably coupled enables to couple the marine growth removal system with the pile in a clamping manner which here means that the pile provides guidance to the marine growth removal system during rotation of the marine growth removal system along the circumference of the pile.
  • In an embodiment, the marine growth removal system comprises a driving system which in use is in contact with the pile wall section for moving the marine growth removal system around the circumference of the pile.
