Abstract: A bolted joint of an offshore structure comprises first and second connecting elements, wherein the first connecting element forms part of an offshore tower or an offshore platform and the second connecting element forms part of a foundation structure. The first connecting element comprises a first flange and the second connecting element comprises a second flange, wherein the first and second flanges abut each other with through holes in alignment. One of the first and second connecting elements comprises an outer peripheral skirt covering a butt joint between the first and second flanges and defining an outer annular space surrounding the butt joint, One of the first and second connecting elements comprises a peripheral collar, the skirt and the collar confining the annular space, the sealing element being a compressible sealing element sandwiched between the skirt and the collar.

Abstract: The invention refers to a pile for an offshore monopile type foundation structure comprising an elongate cylindrical steel tube comprising a first length with a first wall thickness, a second length with a second wall thickness, wherein the second length comprises several reinforcement ribs extending longitudinally and equally spaced apart from each other over the entire second length.
