A method and apparatus for tra nsf erring fluid from a rotor (140) of a t op drive apparatus to a non-rotating conduit, (101, 102) such as a gooseneck , the rotor (140) rotating at a working speed, characterised in that a seal (109) is arranged between said rotor (140) and a speed reducer apparatus (16 0) and a further seal (107) arranged between the speed reducer apparatus (16 0) a nd the non-rotating conduit (101, 102), the method comprising the step of the speed reducer apparatus (160) rotating at a speed slower than the wor king speed, such that the seal (109) and further, seal (107) each rotate at slower speed than the working speed.
