Abstract
Method for mounting a super structure over a top end of a foundation pile, wherein the top end has a truncated conical shape and the super structure has an opening fitting over said top end, which opening preferably has a truncated conical peripheral surface fitting over said top end, wherein a guide structure is placed at said top end, comprising at least one sloping guide surface, where after said super structure is lowered over the guide structure onto the top end of the foundation pile.
Claims22
Method for mounting a super structure over a top end of a foundation pile, wherein the top end has a truncated conical shape and the super structure has an opening fitting over said top end, which opening preferably has a truncated conical peripheral surface fitting over said top end, wherein a guide structure is placed at said top end, comprising at least one sloping guide surface, where after said super structure is lowered over the guide structure onto the top end of the foundation pile.
Method according to any one of the previous claims, wherein the guide structure comprises an upper part comprising or forming the guide surface and a lower part, wherein said lower part is inserted into an open end of the top end.
Method according to any one of the previous claims, wherein the guide structure and the super structure are suspended from a support frame, wherein the guide structure is suspended such that it extends at least partly below the super structure.
Method according to any one of the previous claims, wherein the super structure is a platform with an upper side and a lower side, and wherein the said opening extends through the platform, from the upper side to the lower side.
Method according to any one of the previous claims, wherein as a guide structure an open structure is used.
Method according to any one of the previous claims, wherein by lowering the super structure onto the top end of the foundation pile a slip joint is formed between the super structure and the top end of the foundation pile.
Foundation pile for supporting at least one super structure, especially a monopile for mounting at least a platform by a slip joint, wherein the foundation pile is provided at a top end with a removable guide structure for guiding said super structure relative to the top end during mounting of said super structure.
