The invention relates to a method of upgrading a knuckle-boom crane (100a) to a heave-compensating crane (100). The method comprises: i) providing a knuckle-boom crane (100a) having a crane base (110), a main boom (121) pivotably mounted to the crane base (110), and a knuckle-boom (130) pivotably mounted to the main boom (121); ii) removing the knuckle-boom (130) from the main boom (121); iii) mounting a main boom extension (122) to the main boom (121) for increasing the length of the main boom (120); iv) mounting a heave-compensating boom (140) at a far end (122e) of the main boom extension (122) such that the heave-compensating boom (140) extends in a downward vertical direction (Z) in operational use of the heave-compensating crane (100), wherein the heave-compensating boom (140) is configured to be pivotable with respect to the main boom extension (122) in both horizontal directions (X, Y) defined with respect to the downward vertical direction (Z), and v) providing a heave-compensation system (110) to the knuckle-boom crane (100a), wherein the heave-compensation system (110) is configured for compensating for horizontal variations by controlling the orientation of the heave- compensating boom (140) relative to the main boom extension (122), and for compensating the vertical variations by means of a further vertical heave-compensation system (110), such as a winch-based heave-compensation system. The invention further relates to such heave-compensated crane as such.
