Royal Dutch Shell Oil Company issued a statement on the 24th, saying that since the closure of the safety valve of the damaged pipeline on the 19th, the company’s offshore oil equipment in the North Sea no longer had an oil spill.
Shell said in a statement, "Since 19th, no oil has leaked from the oil line or valve. At present, we are still taking continuous monitoring measures to ensure that there will be no further oil spill accidents."
A total of about 1,300 barrels of oil leaked into the North Sea within a 9-day period beginning on August 10 when a submerged oil pipeline from Shell began. Shell maintenance personnel finally closed the safety valve where the oil spill was located on the 19th and successfully terminated the oil spill accident.
Shell said that a reconnaissance flight report conducted on the 23rd said that there was no apparent oil layer on the sea.
At present, about 660 metric tons of oil (close to 4,000 barrels) still accumulate in pipelines that have been depressurized and closed. Shell is currently assessing this to determine which method to use to safely clean up the accumulated oil. The cleaning process may take several weeks.
Hugh Shaw, the representative of the British Department of Energy and Climate Change, said that after Shell took effective block action, the risk of more oil being leaked was significantly reduced. He said that to confirm the exact location of the oil spill takes Shell for three to four days.
The Scottish government issued a statement saying that the preliminary environmental impact assessment did not find that the oil spill had an impact on birds and marine life, but the Scottish government stated that it will continue to monitor the situation.
[Event Review] Royal Dutch Shell said that as of now, its drilling oil spill in the North Sea region of the United Kingdom has leaked about 1300 barrels of oil and the leak rate is less than five barrels per day.
Comprehensive media reported on August 15, Royal Dutch Shell said on the 15th, on the 10th occurred in the company's oil spill in the British North Sea area GannetAlpha drilling platform, about 1300 barrels of oil has been leaked into the sea.
Glen Cayley, chief technology officer of Shell Europe’s exploration and production activities, said that it is difficult to estimate the total amount of leakage, but so far it has already leaked 216 tons of oil, or 1300 barrels. Shell said the current leak was leaking at less than five barrels a day.
Ultra-high frequency induction heating equipment is a kind of equipment developed for surface quenching by applying electromagnetic induction principle and modern power electronic technology. Surface heat treatment process in which the workpiece is heated locally by an induced current. This heat treatment process is often used for surface quenching, but can also be used for local annealing or tempering, and sometimes for bulk quenching and tempering.
Uhf induction heating equipment adopts IGBT efficacy, soft switching resonant dual control and frequency automatic tracking system, MOSFET devices and unique frequency conversion technology, high frequency operation is stable. Uhf INDUCTION heating equipment with constant current and power control function, greatly optimize the metal heating process. Under the same conditions, it has 50% energy saving compared with the traditional high cycle electron tube heating equipment, no high cycle radiation, no high cycle drying. Reduced power load and power capacity, with 100% full load design, UHF induction heating equipment can work continuously for 24 hours without interruption. With automatic heating, insulation, cooling three periods of function Settings, is conducive to improve the heating quality of UHF induction heating equipment, simplified manual operation. Uhf induction heating equipment can be selected according to the power and frequency. The higher the high frequency, the shallower the heating depth, and the lower the high frequency, the better the diathermy. Induction heater 1 ~ 20KHZ high frequency automatic tracking.
UHF heating equipment has the advantages of high frequency, small size, light weight, energy saving, solid and beautiful solder joints, almost unlimited welding part shape, surface pattern will not be damaged, the metal internal crystal structure unchanged, small annealing range and so on. , no obvious welding scar, widely used in metal glass manufacturing, electrical and electronic industry connector welding, small relay internal non-contact welding, refrigeration industry high pressure welding, jewelry industry parts welding, manufacturing metal jewelry and process welding.
