Abstract
A system and method for servicing subsea wells with a flexible riser. The flexible riser can be modified for use either with wireline or through the flow line tools. The flexible riser eliminates the requirement for motion or heave compensating equipment associated with rigid marine riser systems. The flexible riser, lower riser package and associated surface support equipment can be used to obtain vertical access to a subsea well without the need to use a drill ship or semisubmersible.
