The P-70 has left the shipyard in Qingdao, China, to travel to Brazil and will arrive at Atapu field in the first quarter of 2020. The start-up of the operation will take place after the mooring and interconnection work of the first producing well.
The P-70 platform is part of the replicant series, which currently responds to pre-salt production, with operation already started on units P-66, P-67, P-68 and P-69. They take their name from being part of a standardized set of production platform designs. By repeating the same project over and over there is a gain in scale in productivity and efficiency, as well as in safety and operation itself.
The P-70 will be transported to Brazil by the so-called dry tow mode, meaning that instead of being driven by ocean tugs, the unit is loaded onto a semi-submersible heavy lift ship ( for heavy cargo transportation). There will be 78 thousand tons, which corresponds to the weight of 220 747 boeings, which will be millimetrically accommodated on the vessel. This will cut travel time from China to Brazil by about 40 days. Worldwide, such a maneuver has only been performed once: the P-67, the second unit in the replicant series.
The P-70 will have the function of separating oil from gas and water during the production process, storing it in cargo tanks and finally transferring it to oil tankers, which will be responsible for its transportation. The unit will produce through 13 producing wells and six injector wells, and will have the capacity to process 150,000 barrels of oil (bpd) and 6 million cubic meters of natural gas per day.
Oil processing: 150,000 barrels / day;
Gas treatment and compression: 6 million m³ / day;
Injection water treatment: 200 thousand barrels / day;
Storage Capacity: 1.6 million barrels of oil;
Depth anchorage: 2,200 meters;
Overall Length: 288 meters;
Width: 54 meters;
Height: 31.5 meters.
