1. A method of performing an operation on a vessel assembly, said vessel assembly comprising
a vessel, said vessel comprising a top wall, a bottom wall and an upright wall extending from the bottom wall to the top wall, said top wall, bottom wall and upright wall defining a lumen,
a superstructure on top of the vessel, said superstructure comprising
a bearing, said bearing comprising an upper race member, a lower race member and roller bodies between said upper race member and said lower race member, said lower race member being attached to the superstructure, and
a locking nut for locking the bearing, said locking nut comprising an inner thread,
a rotor, said rotor comprising
an upright, rotatable shaft, said shaft comprising i) a top shaft section extending above the top wall and ii) a bottom shaft section in said lumen,
said top shaft section being provided with said upper race member, allowing the rotor to rotate along a shaft axis of the upright, rotatable shaft in line with the axis of rotation of the bearing, and
said top shaft section comprising an outer thread for engaging the inner thread of the locking nut to lock the upper race member at a desired location on the top shaft section;
and
a plurality of rotor elements attached to said bottom shaft section;
wherein the rotor is stopped and the operation is performed;
characterized in that
the top shaft section comprises at a location above the upper race member a first member chosen from a male member and a female member for engaging a device, said device having
a top end, and
a bottom end, said bottom end comprising a complementary second member for engaging the top shaft section, said complementary second member being chosen from a female member and a male member;
wherein
the device is connected to the top shaft section of the shaft,
the rotor is lifted by lifting the shaft at its top end section using the device, and
the locking nut is rotated upwardly along the top shaft section of the rotor, following which the operation is performed.
