A method for up-ending a longitudinal structure, e.g. a monopile, e.g. as a foundation of an offshore wind turbine. Use is made of a crane comprising a boom that is moveably mounted to a crane housing to allow the boom to pivot relative to the crane housing about a substantially horizontal first pivot axis. The crane comprises three main hoisting systems. The method comprises the following steps:a) providing a longitudinal structure with an upper end and a lower end in a substantially horizontal orientation;b) connecting the middle hoisting block of the three main hoisting systems and one of the outer hoisting blocks of the three main hoisting systems to the upper end of the longitudinal structure;c) connecting the other outer hoisting block of the three main hoisting systems to the lower end of the longitudinal structure; andd) operating the respective winches of the three main hoisting systems until the longitudinal structure is in a substantially vertical orientation with the upper end above the lower end.
