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 (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.

Remora is a Norwegian company, focused on providing solutions for offshore O&G loading. The company was established 2002 and has its head office in Stavanger, Norway and an office in Houston. Remora does business using a ship-owner structure by building, owning, leasing and operating HiLoad units. The range of HiLoad applications spans from offshore loading of crude oil, turret mooring of FSOs and FPSOs, as well as a mobile propulsion or DP system for seagoing vessels such as barges and floating rigs. The HiLoad concept is an innovative offloading solution which utilizes a ballasting system combined with a large square area of friction rubber which enables the HiLoad units to replace the water pressure on the tanker hull with no mechanical connection…

Like I recently stated, bad thing happen real fast, in this case no one even knows exactly why things happened but no real harm was done since the Dynamic Produce FPSO, belonging to Brazilian contractor Petroserv, was down for maintenance since last Sunday, with the well being plugged and the pipes purged of O&G. Therefore, when the a pipe section connecting the FPSO to the well ruptured (it´s still not clear at what depth the rupture occurred or even how many ruptures there were), there was nothing in them to spill out, avoiding what would have been the first serious pre-salt production accident resulting in a oil spill. It is also…

A look at how DP systems work and their importance to ships, vessels and rigs working on offshore O&G operations. The main contribution Kongsberg has made to the offshore O&G industry was by developing DP systems for diving support vessels in the 1970s. This significantly increased the efficiency and safety of diving operations. Since then, the offshore and maritime industries have benefited from the advances made to their DP systems. In more recent years these advances have been applied to the cruise industry with dynamic positioning systems for maneuvering and the complex task of precise position keeping. For optimal deepwater drilling the Kongsberg Riser Management System (RMS) assists in all phases of the drilling operation.

With the continued growth and the high potential of the Brazilian O&G market, the demand for Kongsberg DP systems in ships, support vessels, FPSOs and MODUs is steadily increasing and Kongsberg Maritime do Brasil S.A is expanding and enhancing its presence and investments in the country. Kongsberg Maritime AS, has been engaged in various technological areas related to marine activities for more than 50 years and have been present in Brazil since 1980. They are continuously making efforts to develop their products, organization and employees to accommodate client needs. For their Brazilian operation this focus on client needs is being enhanced by increasing their physical presence in Brazil.
