Siemens recently provided an advanced power system for the D90, a semi-submersible drilling platform with the deepest drilling depth and deepest drilling depth of CIMC Raffles Offshore Engineering Co., Ltd. ("CIMC Raffles"). Siemens' advanced power pack system covers “one-stop†solutions from low-voltage switchboards for high-voltage switchboards to transformers, drilling inverters, propulsion drives and propulsion motors, making the platform more stable, reliable and efficient. The year is galloping on the sea.
The D90 deep-sea semi-submersible rig is based on the Frigstad D90 basic design and is 117 meters long, 92.7 meters wide and 118 meters high. With a maximum water depth of 3,658 meters and a maximum drilling depth of 15,240 meters, the D90 can operate in 99% of the world's waters. The power pack system capacity provided by Siemens is equivalent to the electricity consumption of a city with a population of 500,000.
In addition, the platform is equipped with the world's leading Siemens DP3 closed-loop power system. The Siemens DP3 closed-loop power solution guarantees energy and safety for the platform, reducing oil consumption by 11% for drilling platforms, reducing nitrogen oxides by 35% and carbon dioxide emissions by 20%. In addition, when the generator on the platform suddenly fails, through the DP3 closed-loop power solution, the standby generator can be started in a very short time, so that the platform can obtain continuous power, ensure safe and stable operation, and reduce the maintenance cost of the host by 50%. .
Lin Bin, Executive Vice President of Process Industry and Drives Group, Siemens (China) Co., Ltd. said: "With our cutting-edge technology and advanced experience in industrial digitalization, Siemens is willing to provide the latest in the offshore drilling industry for local companies such as CIMC Raffles. And the highest level of technical support to help it maintain its industry leading position."
Siemens launched DP3 closed-loop power technology in 2010 and is the first in the world to apply this technology to real ships and obtain classification society certification. This technology can effectively reduce host operation and maintenance time, improve host operation flexibility and fuel economy, and reduce greenhouse and harmful gas emissions. At present, Siemens DP3 closed-loop power technology has been integrated and applied in more than a dozen real ships around the world.
Marine engineering equipment is called “flowing land†and is a strategic tool for the development of the offshore oil industry. The “Made in China 2025†national strategy also ranks the offshore equipment industry as one of the top 10 areas supported by the industry. CIMC Raffles is a leading international offshore equipment company and the only domestic company with the capacity to build large-scale deepwater semi-submersible drilling platforms. Since the first cooperation between the two parties in 2005, Siemens has provided a power pack system for the six semi-submersible platforms successfully delivered by CIMC Raffles. They are currently operating in the South China Sea, the Norwegian North Sea and the Brazilian waters.
Concerned about surprises
Pe Plastic Sheet, full name is Polyethylene Sheet.
Physical properties: PE plastic Sheet is the most simple structure of the macromolecular organic compounds, the world's most widely used polymer materials, composed of ethylene polymerization, depending on the density is divided into high density polyethylene, medium density polyethylene and low density polyethylene.
(1) LDPE Sheet
Low density polyethylene Sheet (also known as high pressure polyethylene Sheet)
(2) LLDPE Sheet
Linear low density polyethylene
(3) MDPE Sheet
Medium density polyethylene
(4) HDPE Sheet
High density polyethylene (also known as low pressure polyethylene)
(5) UHMWPE Sheet
Ultra high molecular weight polyethylene(6)Modified polyethylene sheet
Chlorinated polyethylene (CPE) and crosslinked polyethylene (PEX)
(7)Ethylene - ethylene copolymer
Ethylene/propylene copolymer (plastic), EVA, ethylene, ethylene butene copolymer - other olefins, such as octene POE, cyclic olefin copolymer, ethylene/unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH).
Polyethylene, which has a molecular weight of 3 million to 6 million, is known as UHMWPE.
Ultra high molecular weight polyethylene is very strong and can be used for body armor.
1. Papermaking industry: suction box board, scraper, molding plate, bearing, gear;
2. Mining industry: charging barrel, abrasive and adhesive-resistant back lining for warehouses;
3. Chemical industry: acid pump, filter plate, worm gear, bearing;

5. Textile industry:buffer board;
6. Food processing industry: chopping block, refrigerating plant;
7. Wharf: anti-collision board.
1. Acid and alkali resistance, resistance to organic solvents
2. Excellent electrical insulation and static resistance
3, Can still maintain a certain touness even at low temperature
4. Extremely high impact strength
5. Low friction coefficient
6. Non-toxic
7. Low water absorption
8.Lower density than any other thermoplastic plastics (<1g/cm3)
Disadvantages:
PE Plastic sheet have Weak mechanical property, air permeability, easy deformation, easy ageing, brittle, brittle less than PP, easy stress cracking, surface hardness, easy to scratch.
Difficult to print, in printing, surface discharge treatment, cannot electroplating, the surface has no luster.
Specification: the diameter of the PE rod can be produced from 2mm to 250mm. The conventional length is 1000mm, and the length is unlimited.
The thickness of PE sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of10-180mm is 600*1200mm.PE sheet can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited
