摘要： A subsea pipeline (10) is provided with a valve (11) which can be operated between a closed position and an open position to establish access from the pipeline exterior to the pipeline interior. The valve (11) is provided with a connector (13) adapted to connect to a sampling tool (16) comprising one or more fluid sampling probes (21). During operation, the fluid sampling tool (16) is transported from a surface location by an ROV down to the subsea pipeline (10) and connected to the valve. Then, the ROV opens the valve (11), moves a sampling probe (21) from the fluid sampling tool (16), through the valve (11) and into contact with the fluid within the subsea pipeline (10) to take fluid samples from the same. When the sampling procedure is completed, the probe is returned back to the sampling tool, and the valve is closed. The ROV disconnects the sampling tool and returns the sampling tool (16) to the surface.
