SUBSEA WELL HEAD ASSEMBLY FOR USE IN RISERLESS DRILLING OPERATIONS

A subsea well head assembly for use in riserless drilling operations is adapted for enclosing a tubular (20) and comprising a Rotating Control Device (60) and a blowout preventer (40). The Rotating Control Device (60) is adapted for sealing the tubular running (20) while the tubular (20) moves. The blowout preventer (40) is adapted for preventing a blowout from a well bore operated by the tubular (20). A flex joint (50) is provided in between the Rotating Control Device (60) and the blowout preventer (40) enabling the Rotating Control Device (60) to align with the tubular (20).
