Description
Pile cleaning system Background 5 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 10 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 15 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 20 the removal of marine growth from subsea conduits. The disclosed skid and method of cleaning subsea conduits leaves room for improvements.
Summary of the invention 25 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.

According to a first aspect of the invention this is realized with a marine growth removal system for cleaning an erected open ended pile the system comprising; 2 - 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 5 other such that a pile wall section accommodation space extends between the inner frame member and the outer frame member, - a guiding device comprising a guiding means arranged with respect to the pile wall section accommodation space for contacting an upper rim of the pile for providing support and guidance to the marine growth removal system, 10 - a cleaning device provided with the inner frame member and/or the outer frame member for removing the marine growth from the interior surface and/or the exterior surface of the pile.
The outer frame member being coupled with the inner frame member and mutually arranged such that a pile wall section accommodation space extends between the inner 15 frame member and the outer frame member enable a more lightweight and smaller marine growth removal system which is importantly more easy to handle. The more easy handling is also caused by the ability to simply suspend the marine growth removal system over the rim of the pile. In addition, the pile is cleaned faster because the height required for a grout coupling is cleaned at once in one rotation of the marine 20 growth removal system.
Such an erected open ended pile is for example a jacket or a foundation pile ready to support a windmill. These piles typically have a large diameter like from 2,5 meter even up to 11 meter. Such a pile must be cleaned prior to coupling the pile, by using 25 grout, to a construction to be founded, like a windmill.
In an embodiment, the marine growth removal system comprises a main frame coupled with the inner frame member and outer frame member, wherein the main frame extends across the inner frame member, the outer frame member and the pile 30 wall section accommodation space there between.
