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…
The Prirazlomnaya Rig Details – Part 2
The Prirazlomnaya platform was designed for operation in the most hostile climate with sub-zero temperatures and a solid ice cover that remains for nearly six months in the production area, where up to 22 storms take place every year. An average storm may last for 9.5 days with an average wave height of 3.9 meters and the maximum wave height reaching 13+ meters. It is designed to resists ice pressure, sea waves and earthquake magnitudes from 5 to 6 on the Richter scale. Built by Sevmash Production Association, the Prirazlomnaya offshore ice-resistant oil-producing platform (OIRFP) is a key development facility. The platform will ensure well drilling, oil production, storage and offloading.
Flaming Rig – No Worries
As fires blazed on an old Petrobras production rig at the Campos Basin on the 19of January, silence was the rule, as has always been the rule with such trivial emergencies such as a large fire on an oil rig. I must be thick or something, but I consider it strange that a major fire on an oil rig only comes to public notice nearly ten days after it happened. Actually I shouldn´t complain because normally these small accidents would never have become known. Hey, no one even died, right, that a failure on an oil transfer pump caused a massive blaze, including a full on electric fire, which took Petrobras´s onsite fire brigades all of half an hour to control, is no big deal! Now imagine that this kind of attitude has been going on for decades.
ROV Demand Still Increasing in Brazil
With a number of new O&G discoveries popping up nearly continuously in Brazil, both in shallow and deepwater, there has been a significant increase in ROV demand by operators, not only the major players but by all players involved on the Brazilian oil boom. In general the delivery of a complete ROV system may take around nine months, this includes the delivery of key equipment such as heavy duty winches, power and control umbilicals, flotation foam blocks, control modules, tooling kits and backup equipment. Here in Brazil, ROV manufacturers, which are basically all foreign companies with local offices, have been increasing their local stocks of ROV systems.
