Abstract: An extensible tubing and a method are for facilitating transfer of fluid between a fluid supplying device and a fluid receiving device. The extensible tubing is configured for connection to the fluid supplying device and for receiving a fluid therefrom. The extensible tubing has a housing with a first end portion and a second end portion A core is arranged inside the housing and secured thereto. A pipe is arranged between the housing and the core. The pipe is axially movable between a retracted position wherein a seal prevents fluid from passing between the core and the pipe, and an extended position wherein the seal does not prevent fluid from passing between the core and the pipe. A piston and a biasing means are for urging the pipe towards its retracted position.

Abstract: A method is described for supply of liquid from a liquid storage to a casing string (10,12, 14..) which from a deck (16) on an installation is conveyed down in a well with the help of a pipe handler comprising an elevator, where the liquid is supplied via an uppermost casing (10) which is added to the casing string, and the liquid is supplied through a filling pipe (30) via an outlet nozzle (36) to the top of the casing (10) already during the pipe's (10) screwing into the casing string (10, 12, 14..) where the filling pipe is extended during the liquid supply until the casing string is being lowered down to a position where it is securely locked to the deck (16), and liquid is added to a suitable level in the casing string.
