(84) = (54) Title: IMPROVEMENTS IN PARTICULAR RELATING TO SUBSEA WELL CONSTRUCTION Fig. 6 co 00 O C (57) : In an embodiment there is described a method of constructing a subsea well. There is also described an associated unit. The method may comprise the steps of: providing a unit comprising at least one component of a flow control assembly, the flow control assembly to be operable for controlling a flow of injection or production fluid during operation of the well after the well has been constructed; lowering the unit through sea toward a seabed; receiving part of the unit in a subsurface of the seabed to anchor the unit in place, part of the unit projecting above the seabed, whereby said component of the flow control assembly is positioned in the projecting part; and performing at least one well construction operation through a bore in the unit.
