Abstract
A fiber optical sensing cable is inserted into an underwater well by: connecting a housing (A) comprising a coiled or spooled U-shaped fiber optical sensing cable () to the wellhead () of the well () such that an opening () in the wall of the housing (A) is connected to a guide tube () extending into the underwater well (); —inserting the U-shaped nose section (A) of the fiber optical sensing cable () via the opening () into the guide tube (), thereby uncoiling at least part of a pair of substantially parallel sections of the fiber optical sensing cable of which the lower ends are interconnected by the U-shaped nose section; and connecting the upper ends (B) of the substantially parallel sections of the fiber optical sensing cable to an optical signal transmission and/or receiving unit via e.g. a pair of wet mateable connectors that are connected to a pair of underwater fiber optical transmission cables ().
