Shandong: Building a Dream of Deep Blue, Playing a New Movement of "Harmonious Sea of People and Beautiful Ocean"
On the morning of March 8, 2018, General Secretary Xi Jinping pointed out in his speech at the Shandong delegation that the ocean is a strategically important place for high-quality development and should contribute to the construction of a maritime power.
Three months later, General Secretary Xi Jinping inspected Shandong after attending the Shanghai Cooperation Organization Qingdao Summit.
Along the inspection route of Xi Jinping, it can be found that many inspection sites are located on the coast of the Yellow Sea, which is related to the marine strategy.
In his heart, the word ocean is very important.
When inspecting the Yantai Base of Shandong CIMC Raffles Offshore Engineering Co., Ltd., General Secretary Yin Yin asked—
"Basic and core things cannot be obtained or bought. We must rely on our self-reliance and independent innovation to achieve. I think you have this confidence, and I hope you will rise to the challenge and make persistent efforts."
Bearing in mind the entrustment of General Secretary Xi Jinping, go ahead and start a new situation.
In the report of the 12th Party Congress of Shandong Province, "ocean" appeared in as many as 30 places and became a high-frequency word.
Looking at the past, Shandong's total marine economy ranks second in the country, and national-level marine ranches account for nearly 40% of the country. Looking at the future, Shandong will be strong in the sea, and take independent innovation as the pen to build a modern marine industry system and build a "human sea". Harmonious and Beautiful Ocean" continues to write new chapters.
Deeply ploughing the blue sea and the future of animal husbandry and fishing: "Blue Granary" lights up the fishing fire of thousands of families
In the early morning of June 2, in the bay area not far from the wharf of Nanhuangcheng Island, Changdao, Shandong, fishermen's small cages were lined up in rows, and fishing boats shuttled between them from time to time on the sea.
63-year-old Wang Maoyi is feeding the black squid he breeds. The high-raised bait draws a beautiful arc under the blue sky and sprays it into the cage under his feet. Juveniles gather on the water surface like a dark cloud to grab food happily.
A few months later, this box of 30,000 juveniles will enter the "Jinghai No. 001" deep-sea intelligent cage independently developed by Yantai CIMC Raffles to start their deep-sea journey.
Starting from Nanhuangcheng Island by speedboat, you can see the "Jinghai No. 001" standing majestically in the distance.
As the main body of the implementation of the "Hundred Box Plan" for the largest single-unit equipment-based marine ranch in Asia, the Jinghai series of cages are well-known.
These behemoths with a length and width of 68 × 68 meters, a depth of 40 meters, and an effective breeding volume of 70,000 cubic meters are equipped with various systems such as 5G communication, marine data monitoring and underwater monitoring, which realize the automation of cage platform culture, Intelligent, the annual output of single cage is more than 600 tons.
In the fishery industry chain, the cage is a "bridgehead" for the modern farming model.
With such a huge cage platform, only 4 staff members can complete the fish farming task of more than 1,000 tons that used to take 30 or 40 people to complete through automatic feeding, underwater monitoring, underwater net washing and other equipment.
"The reason why our cages are called deep-sea cages is that the water depth reaches 31 meters, the flow rate reaches 1 m/s, the water can be exchanged once within 2 minutes, and the seawater self-purification ability is strong; the second is the distance The coastline is 4 to 5 hours away by boat, and it is in the core position of the Bohai Bay." said Zhang Jiayu, general manager of Yantai Jinghai Marine Fishery Co., Ltd.
Taking advantage of the advantages of large deep currents and abundant bait resources in the open sea, Jinghai series cages are equipped with artificial and natural double bait and clean water to truly realize the intelligent equipment-based "wild-like" breeding in the deep sea.
The ocean is a strategic location for high-quality development, and the construction of marine pastures is an important means to promote the transformation and upgrading of traditional fisheries to modern fisheries.
As an important measure for Shandong to develop a marine economy and build a marine economy, the "Hundred Boxes Plan" will build 100 deep-sea intelligent aquaculture cage platforms. industrial chain.
At present, there are 6 large-scale intelligent cage platforms in the Nanhuangcheng sea area located at the intersection of the Yellow Sea and the Bohai Sea at 38 degrees north latitude.
One fish drives an industrial chain, and the marine ranch has initially established a "cage breeding and shared relay" model, opening up the deep-sea industrial chain and hoarding "blue granaries".
Two weeks ago, Wang Maoyi sold nearly 20,000 catties of juvenile black squid to Jinghai Company, with a profit of more than 400,000 yuan.
This old fisherman who made his living from fishing in the 1990s and has experienced wind and frost has seen the real money brought by the "big fishing belt and small fishing", and also witnessed Shandong's fishery from primitive fishing to scientific and technological breeding, from passive and extensive. to the process of refined development.
"It took me two and a half years to raise black squid to raise more than 1 kilogram, and many fish farmers took three years. After the fish become adults, they have to find sales everywhere, and they are even more worried when they encounter an epidemic." Wang Maoyi said that he now only If you need to raise fry for half a year, you can sell them to Jinghai Company and put them in the cages of marine pastures to continue farming.
"The incidence and risks of black scorpion farming in the Inner Bay are high, and many individual fish farmers are fighting each other. Even after raising adult fish, it is difficult to sell fish with a scale of less than four or five thousand kilograms and less than 1 kilogram. All rotted in the sea and smashed in the hand."
Today, "Jinghai 001" has signed a cooperative breeding agreement with more than 100 fishermen from the fishery cooperatives on the island.
Through the model of "leading enterprises + cooperatives + fishermen + scientific research units", Yantai has effectively integrated 160,000 mu of sea area, realizing the largest transfer of sea area use rights in the province, and radiating and driving more than 20,000 fishermen to increase production and income.
The ocean needs to rest and recuperate, and the fishing season is closed from May to September every year.
For fishermen, requesting resources from deep seas through this aquaculture model not only broadens income channels, but also provides a demonstration for deep sea aquaculture in China.
"From offshore engineering equipment to the construction of fishery equipment to fish farming, every crossover is a challenge," said Guo Fuyuan, assistant president of CIMC Raffles Offshore Engineering Co., Ltd. and general manager of Yantai Jinghai Marine Fishery Co., Ltd.
Born to the Sea, Prospered by the Sea: Ecological Protection Empowers "Sea Pastoral"
As an important carrier of Shandong's strategy of strengthening the marine province, the marine ranch not only turns the blue ocean into a "marine granary" and a "maritime bank", but also makes the modern fishery aquaculture model on the road of economic development and ecological protection.
Not long ago, in the National Demonstration Zone of the Ocean Ranch on Nanhuangcheng Island, the first batch of "Jinghai Series" deep-water intelligent cages of black carp and perch have begun to be harvested.
In Jiaodong Peninsula, the taste of black squid is often described with one word - "fresh".
"The flesh of black squid is delicious and firm, and the protein is very rich. Jiaodong Peninsula uses it as confinement soup."
Li Xin, marketing manager of Yantai Jinghai Ocean Fishery Co., Ltd., said that the habit of this fish is to love reefs, "We put reefs around the cages, and algae kelp has been attached to it since a few months, and the fish manure is absorbed by the seaweed, attracting some Fish, shrimp, crabs and shells, these creatures have become the food of black mackerel, forming a natural cycle ecosystem, and sea cucumbers, abalone, etc. are gradually growing here.”
At that time, the contiguous aquaculture facilities and extensive bait feeding in the coastal waters resulted in large aquaculture output and heavy pollution.
Today, every reef is like an "ecological bank", with a large number of oysters, red snails and other shellfish enriched on the surface, and a large number of wild fish such as porcupine bream, barracuda, goby, black bream and other wild fish in the reef area kind.
The annual biological resources of the reef-casting area are 2.6 to 6.4 times that of the uncasted reef area.
"Through the construction of marine pastures, the establishment of a healthy marine ecosystem, and the selection of suitable bioremediation species for large-scale breeding can effectively regulate and restore water quality and sediment." Executive Deputy Director of the Institute of Oceanography, Chinese Academy of Sciences Yang Hongsheng said.
"Although our island is far away from the mainland, we can proudly say that what we eat here is the real seafood, and what we eat in other places can only be called seafood." Ge Meng, secretary of the Nanhuang Urban and Rural Party Committee and mayor of the township, introduced that it is natural to eat here. There are more than 100 kinds of sea treasures such as sea cucumbers, abalones, sea urchins, and scallops. It holds many national geographical indications such as Long Island Sea Treasures, Long Island Abalone, and Long Island Sea Urchins. Island".
Nanhuangcheng Island has green mountains and green waters, red tiles and powder walls, masts, and warehouses full of fish and shrimp, just like the paradise described in "Peach Blossom Spring".
Such an ecological picture is naturally inseparable from the credit of the marine ranch.
In recent years, the marine ranch in the waters of Long Island has accumulated more than 1.3 million empty squares of various artificial reefs, proliferated and released more than 30 million fish, and continued to improve the ecological environment of the waters around Long Island.
Not only that, the platform effect of the ocean ranch has also spawned cultural tourism projects.
Today, Nanhuangcheng Island is relying on the marine ranch platform to create a national A-level tourist attraction, further promoting the construction of marine ranch sea fishing boats, sea fishing wharfs, tourist service centers and other supporting facilities, launching a pilot operation of leisure sea fishing clubs, and creating a maritime "idyllic garden" Complex".
In order to promote the diversified and integrated development of marine ranches, Shandong has formulated and issued the "Shandong Province Marine Ranch Construction Plan", and established the spatial layout of "one body, two belts, three districts, four parks and multiple sites". Five types of characteristic marine ranches, such as pastoral type and sport fishing type, implement differentiated development.
Since 2019, in accordance with the goal of "based on Shandong and leading the country", the comprehensive pilot work of modern marine ranch construction has been steadily promoted.
From light blue to dark blue, the background color of farming has changed, and the fishermen have changed the world.
From the decline of relying on the sea to eat the sea, to repairing the ocean, loving the sea and protecting the sea, with the blessing of the marine ranch, "born to the sea and prospered by the sea" has been endowed with a new connotation of ecological civilization construction.
Through the ocean and advancing into the deep blue: independent innovation composes a "blue movement"
On June 13, 2018, General Secretary Xi Jinping came to the Yantai Base of CIMC Raffles Offshore Engineering Co., Ltd. in the rain.
On the dock of the factory, he held an umbrella and waded through the stagnant water to inspect the jack-up workover living platform docked here at close range. Taishan" gantry crane and marine ranch platform, learn more about the manufacturing, maintenance and operation of high-end marine engineering equipment from the person in charge of the company.
"Ocean ranching is a development trend, and Shandong can carry out pilot projects."
"The comments made by the general secretary during the inspection process outlined the ideological connotation and action framework of Jinglue Ocean, and pointed out the direction for us to move forward." said Wang Jianzhong, Secretary of the Party Committee and President of CIMC Raffles.
In the same year, CIMC Raffles established CIMC Blue Ocean Technology Co., Ltd., which took a solid step of "oil-to-fishing" and led the sixth wave of marine fishery in the country.
As an important carrier of Shandong's strategy of becoming a strong marine province, the marine ranch grafts marine engineering equipment technology into the fishery field. With the blessing of high-end large-scale equipment, it helps marine fishery go to the deep sea and reduces the pressure on the coastline ecological environment brought about by the previous breeding model.
The key to activating the "chess eye" of marine ranching is to speed up the pace of marine technological innovation.
As an old-fashioned offshore engineering equipment enterprise established in 1977, Shandong Yantai CIMC Raffles took independent innovation as its pen, and handed in the answer sheet to General Secretary Xi Jinping's entrustment with "Made in China" and "Scientific and Technological Innovation".
Offshore engineering equipment is called "mobile land" and is a strategic weapon for the development of the offshore oil industry.
The most complex and technologically advanced semi-submersible drilling platform is the "jewel in the crown" of the offshore engineering equipment industry, and it is the hope for human beings to develop deep-sea energy.
Under the blue sky and white clouds and the sea breeze, the semi-submersible drilling platform "Blue Whale No. 1" seems to be on a miniature offshore island.
According to the relevant person in charge of CIMC Raffles, "Blue Whale No. 1" can be called an "aircraft carrier" in offshore equipment. It weighs 42,000 tons and has a deck area 1.5 times that of a standard football field. From the hull to the top of the drilling rig It is 118 meters high, equivalent to 37 floors, and the construction price is about 700 million US dollars, equivalent to two Airbus A380 aircraft.
It is understood that "Blue Whale 1" adopts a large number of new technologies such as double rigs, hydraulic main lifting, cuttings recovery, and ultra-high pressure well control.
In order to have a close look at the core drilling system, it is necessary to climb up to a platform nearly 40 meters high from the deck. Only here can the double drilling tower system reveal its true colors.
Compared with traditional drilling platforms, the Blue Whale series is equipped with high-efficiency hydraulic double rigs and the world's leading closed-loop power system. The two well core systems work at the same time, which can improve the operation efficiency by 30%.
"The closed-loop power system applied for the first time in China enables the system to flexibly select or designate the engine running online according to different working conditions, save 10% of fuel consumption, reduce emissions, and greatly improve the green performance of the platform."
On the basis of summarizing the sister ships of the same series, "Blue Whale 2" has achieved many major innovations in the construction process of the project. It is currently one of the semi-submersible drilling platforms with the deepest operating water depth and drilling depth in the world, with a maximum working water depth of 3,658 meters. , the maximum drilling depth is 15,250 meters, equipped with DP3 dynamic positioning system, and classified by Det Norske Veritas.
In March 2020, "Blue Whale 2" conducted the second round of combustible ice test mining in the South China Sea, setting two new world records for "total gas production and average daily gas production".
The unknown ocean is constantly exploring.
At the National Two Sessions in 2021, carbon peaking and carbon neutrality will be written into the "Government Work Report" for the first time.
In this context, energy conservation and emission reduction, improvement of energy utilization, and new energy development have become "hot words" nowadays.
In fact, CIMC Raffles started to deploy offshore wind power two years ago, and has achieved leading advantages in the fields of offshore wind power equipment manufacturing, wind farm resource development, transportation and installation, and operation and maintenance services.
Not only that, as offshore wind power enters the parity period, relying on the existing facilities of offshore wind farms, combining wind and fishing with three-dimensional comprehensive utilization of marine resources will be able to better improve the income of offshore wind farms.
In response to the national 3060 call, CIMC Raffles also launched wind power-related and wind-fishing products.
In 2021, the "3060 Series Offshore Wind Power Installation Platform" project was signed in Shandong, launching a number of high-end offshore wind power installation vessels suitable for various complex sea conditions around the world, promoting the development of China's offshore wind power and helping to achieve the "3060" dual-carbon goal.
The sound of the waves is bursting, and the future can be expected.
The 3,024.4-kilometer coastline agitates Shandong Xianghai Tuqiang's ambition, playing a grand movement of passing through the ocean and advancing into the deep blue.
