Remote Deepwater Coring and Sampling – Part 2
Helix Energy Solutions has a different concept for using an ROV in conjunction with a subsea coring and sampling rig. Helix’s system, the ROVdrill Mk. 2 actually places the ROV and the rig together inside a cage. Both the Forum Rovdrill and Helix’s ROVdrill MK. 2 are capable of deepwater operations and have their advantages and disadvantages. In this post we’ll take a look at the Helix ROVdrill MK. 2 capabilities. Helix Energy Solutions Group, Inc.’s robotics subsidiary, Canyon Offshore Limited (U.K.), which has an extensive fleet of proven trenching equipment and ROVs, also commercializes the ROVdrill Mk.2 systems. Canyon Offshore’s…
Riserless Light Well Intervention for Deepwater Wells
Riserless Light Well Intervention (RLWI) enables operators to increase the oil and gas recovery rate from subsea oil wells. It allows rapid well access by using smaller DP vessels instead of larger semisub drilling rigs or drillships. RLWI also enables subsea well intervention without having to use a drilling riser package connected to the subsea stack, which is topped by the blowout preventer system. Riserless intervention is a cost-saving alternative to drilling rigs, reducing mobilization time for life-of-well operations including wireline, logging, light perforating, zone isolation, plug setting and removal, and decommissioning. The technology is based on wireline well maintenance, where the cable is routed via a subsea lubricator system into the subsea well.
