Abstract

A closed operation subsea well tool assembly with a flushing system flushing a first fluid in the mainbore (15) of the tool assembly (1). The flushing system of the tool assembly comprises a container (19) with a second fluid, a pump (2), a swab valve (20) in the top of the main bore (15), an inlet (3) in the bottom of the main bore of the tool assembly, which is connected to the pump. Outlet(s) (5a, 6a) are below the swab valve, configured to guide out the first fluid from the main bore. A fluid channel (7) extends from the outlet (5a, 6a) and down to channels of the wellhead module (10) or the wellhead (31). Methods using the tool assembly are also disclosed.A closed operation subsea well tool assembly with a flushing system flushes a first fluid into the mainbore (15) of the tool assembly (1).
