On the morning of August 4th, the first large-scale equipment delivery ceremony for Hainan Refinery's 1 million tons/year ethylene and refining expansion project was held in Yangpu, Hainan
.
After receiving the task of transporting large-scale equipment from Hainan Refinery and Chemical, the shipping company carried a 5,000-ton deck carrier, assembled a newly purchased 60-axis full-steering self-propelled hydraulic trolley (SPMT) imported from Germany, and organized the company's own transportation team.
Ningbo Ro-Ro boarded the ship and successfully arrived at Hainan Refinery's self-contained terminal after a voyage of more than 1,000 nautical miles
.
●At 9:48, the commander-in-chief gave an order, gun salutes were fired, fireworks filled the sky, and the vinyl tower pick-up and unloading officially began
.
● The first is to lay a springboard to fill the gap between the deck ship and the shore to provide the vinyl tower landing conditions
.
●
● Afterwards, the hydraulic trolley began to be jacked up, and after the upper ethylene tower was lifted into place, the hydraulic trolley began to roll on and unload the ship
.
●
● At 3:00 pm, the hydraulic trolley completed the unloading.
According to the ethylene tower transportation plan formulated in advance by the project, it took 4 hours from the self-provided wharf via the road outside the factory area to reach the ethylene tower placement position in the factory area
.
●
● Complete the unloading of the vinyl tower at 8 pm
.
●
It is understood that the ethylene tower delivered by Sinopec Shipping Company this time is the core equipment in the critical path of Hainan Refinery's 1 million tons/year ethylene project.
The tower is 90 meters long, 6 meters in diameter, and has a total manufacturing and processing weight of 560 tons.
The Xiangshan manufacturing plant of the engineering company completed the overall manufacturing and processing, and was shipped to the project construction site two months ahead of the contract delivery date.
Non-standard equipment

The 4,060-ton "steel giant house", the largest offshore booster station in China, was shipped On August 6, the first offshore deep-water offshore wind farm in China, which was surveyed and designed by the Guangdong Institute of Energy China and carried by Guangdong Thermal Power - Huadian Yangjiang Qingzhou San 500 MW The offshore booster station of the offshore wind farm has completed all construction work and will be shipped from Nantong to the project sea area
.
A "steel giant house" equivalent to the height of an 8-story residential building, from the river to the sea, honked its horn and set sail
.
The overall size of the upper block of the offshore booster station shipped this time is about 52.
3 meters x 46.
8 meters x 22.
9 meters, the weight of the single unit is about 4060 tons, the size and weight are large, and the transportation distance is long.
Axis) will be ro-ro loaded on the ship at the wharf, tied and fixed on the transport bracket, and will be transported by sea for about 1,030 kilometers (560 nautical miles), and it is expected to be transported to the wind farm waters after 8 days
.
The offshore booster station is the power collection center of the offshore wind farm, which is equivalent to the "heart" of the wind farm.
Its design level and construction quality are crucial to the safe and stable operation of the project
.
The offshore booster station of Qingzhou III Project is the largest offshore booster station in China, with a total weight of 4,060 tons.
It adopts an integral structure with a "cross"-shaped channel inside, and is equipped with professional equipment such as electrical, fire protection, and HVAC.
The overall equipment is localized The rate is over 95%
.
Guangdong Institute gives full play to the advantages of offshore wind power design technology, and draws on the design and operation and maintenance experience of multiple offshore booster stations, and conducts in-depth optimization design of the upper block of the booster station, which meets the functional requirements and takes into account the construction economy and operation and maintenance.
It has been unanimously praised by all parties involved in the construction
.
During the shipment and construction, the Guangdong Thermal Power Project Department overcame many unfavorable factors such as tight construction schedule, heavy tasks, three-dimensional cross construction and frequent occurrence of typhoon and bad weather.
, carried out a number of calculation and analysis on the sea binding design, tooling strength, ship stability, load adjustment analysis and mooring calculation for the transportation of large and heavy objects.
The technology of loading construction is feasible
.
After selecting the appropriate tide level time period, seize the opportunity to ensure that the ship loading work is carried out in an orderly manner, and strictly control the quality of loading and lashing
.
The project is China's first offshore deep-water offshore wind power project with the farthest offshore, deepest water depth and largest single-unit capacity.
It is located in the sea near Shapa Town, Yangjiang City, Guangdong Province, with a total installed capacity of 500 MW and a total of 30 units of 8.
3 MW, 37 sets of 6.
8 MW wind turbines, supporting the construction of offshore booster stations and onshore centralized control centers
.
After the project is completed, it can provide 1.
547 billion kWh of clean electricity every year.
Compared with coal-fired power plants of the same scale, it can save 478,000 tons of standard coal and reduce carbon dioxide emissions by 451,000 tons per year.
Accelerating the realization of the "3060" goal is of positive significance
.
