... riserless light well intervention system is composed by coiled tubing downline system, umbilical and wireline system, and well control package. The existing coiled tubing and riserless light well intervention system unfortunately is not designed for open water intervention operations, especially...

... to the downline system must be addressed and overcome because it can collapse the downhole equipment that had previously been used only in shallow waters. With the development of deepwater fields, coiled tubing (CT) provides several advantages over regular downlines. Considering that the pipelines are longer than...

... tubing (CT) downlines are deployed with a clump weight through open water and connected to the subsea safety module and well stimulation tool. The depths of these operations were on the order of 1,372m (4,500 ft) and quite similar (±100 ft). Fluids (including acid) were pumped continually through...

... Abstract Offshore pipeline pre-commissioning activities normally involve the use of downline to permit the communication between surface equipment (normally rigged up in a vessel or rig) and the subsea pipeline injection/vent point. Recently, a major operator in Brazil deployed a 1 3/4...
