"Next, I would like to invite our chief engineer to speak." Ding Zhongyi said.

The chief engineer of the civilian products department of Jiangnan Shipyard has messy hair, and the overalls he wears are stained with engine oil, and his appearance and style are somewhat similar to Zhao Chunda.

Chief Engineer Fang pointed to the whiteboard and said while writing: "Okay, I will talk about the technical issues directly, and I hope that the comrades of the institute will discuss it together." The 12 drillships we are about to complete are all built in the shallow water drillship model in terms of the original hull design, steel plate selection, hull structural strength, and construction mode. It is substantially different from the working performance and deck space that the first source ship needs to have. Among them, several problems that need to be solved urgently are: first, the stability of the transformed ship is required to be good, and it can sail safely when the wind and waves are less than 0.4m. ”

Chief Engineer Fang took a sip of tea and continued: "Second, after being equipped with a suspension system, the ship's on-line orientation ability and speed meet the requirements of high-quality control and construction. Third, the seismic resistance of the hull, mechatronic equipment and fuel lines must meet the needs of safe and reliable work for a long time. If the above three problems cannot be solved, the transformation of the ** ship will be unsuccessful and will also affect production. ”

The fans in the house creaked. The researchers were taking notes.

Zhao Yuemin exchanged a few words with his father softly, and then spoke: "Chief Engineer Fang is very correct. Although we have the technology of shallow water ** vibrators, how to effectively use it on ships requires close cooperation between the two parties. Let me talk about the suspension problem of the specific ** array technology. ”

Zhao Yuemin took out a few prepared slides and placed them on the slide projector, and the light was projected from the slide projector and reflected on the white screen.

"Look, there are two ways to hang the ** array in the water, the stern towing type, and the side hanging type on both sides of the hull. Considering the first ship, it is necessary to complete more ** excitation as close to the shallow water area as possible on the shore, which requires the ship to be able to quickly and flexibly turn around and operate online, and at the same time work in the shallow water area without damaging the underwater ** and accessories. Therefore, I think it is more appropriate to use the side crane method on both sides of the hull. ”

"Second, considering the existing space on the deck, if a hydraulic device is adopted to control the retraction and release of the gun carriage, and the ** sinking operation, 4 sets of hydraulic pipelines, 4 hydraulic winches, 4 hydraulic cylinders and a set of hydraulic power stations are required. This is too complicated for the ship, and the equipment and installation are very difficult to equip......"

When Zhao Yuemin was telling, the engineers in those shipyards were secretly surprised. Zhao Chunda's reputation in the oil field, they have heard of it. Unexpectedly, this technical meeting was presided over by his son, who was less than 30 years old.

Moreover, Zhao Yuemin's speech was clear and logical, and he had a solid technical foundation hidden in his speech, which was not particularly commensurate with his age.

Engineers and researchers from both sides held a week-long meeting at the Jiangnan Shipyard and finally decided on a specific plan for the ship's transformation. In addition, the shipyard will carry out the construction and renovation, and the delivery is expected in a month.

Zhao Yuemin is also a thread in the needle, helping shipyards to contact customers in other oil fields. Whether it is Daqing Oilfield or Shengli Oilfield, seeing the excellent qualifications of Jiangnan Shipyard and the patented invention of the Red Star Research Institute, they all happily placed orders.

Ding Zhongyi is also a cheerful person, and in half a month, he delivered ten cement ships to Red Star Industry.

Hu Dong looked at the ten brand-new cement boats next to Shao Lake and slapped Zhao Yuemin's shoulder: "Yuemin, it's all your credit." ”

"Don't, Dongzi." Zhao Yuemin looked at the lake, "At the beginning, I held a board of directors and asked for the establishment of a technical school and research institute, and you supported me unconditionally in Shenchuan, making the decision-making process extremely smooth. ”

"We're brothers." Hu Dong said disapprerovitically, "I know, you Zhao Yuemin are all for the good of the company." ”

A red sun slanted westward, and two young people stood by Shao Lake, looking at a row of cement boats and smirking......

After the cement ship arrived, Hu Dong first carried Hongtashan and Maotai, and invited Xiao Dekai of the Transportation Department and the leaders of the Infrastructure Construction Department to have a meal. Contracted a cement project for the construction of an oilfield site.

In addition, starting from Shaohu Lake and reaching areas that can be reached through the canal, Hu Dongdu is actively pulling projects.

The seventies and eighties were the golden age of the development of cement ships. In the era of steel and timber shortage, the state put forward the policy orientation of replacing steel and wood. Although cement is not rich, it is a little better than steel and wood. As a result, cement was used to replace steel and wood in many fields, and cement ships came into being.

Not only that, the structure of the cement ship can make it multi-purpose. In rural areas, cement ships replace wooden ships transporting fertilizers, agricultural products, and means of production, and steel barges or self-propelled barges and wharf barges are used in inland waterway transportation and shipping.

Hu Dong's cement boats sail through the waterways of various villages and towns. Don't look at the low profit of transportation fertilizer, but the quantity is large and the demand is large. Ten cement boats were moored at the wharf, and early in the morning, there were farmer brothers pulling carts of fertilizer, waiting in line.

Hu Dong specially recruited dozens of crew members for the new fleet. There are generally two types of inland river vessels, one is the act of employing crew (that is, the shipowner hires crew to serve on the ship) and the other is a family ship. Family ships, it is easy to understand that the crew of their husband and wife and relatives or brothers and relatives are combined into a boat, relatively speaking, the combination of this kind of ship is more coordinated, after all, they are all family or family members, and the degree of harmony is a little higher. In the seventies and eighties, many families lived directly on ships.

The work on board is divided into the engine department and the driving department, and the sailing time is four hours in one shift and two shifts a day. There are shifts during the day and night when docking, anchoring, etc., and the daytime shift time does not matter what you do, but if there is a theft or other things you are responsible for, you must get up and be on deck duty at night.

The night is quiet.

A cement boat, smoothly moving on the river.

Zhao Yuemin and Hu Dong sat in the cabin, chatting with the chief engineer.

"The two bosses ......," said the young chief engineer, "I am from Lishui, Zhejiang.

In our village, we all used to make a living by running boats in the creek basin, and more than 40% of our sons inherited their father's business and even three generations of grandparents and grandchildren ran boats. At this point, the chief engineer paused and asked, "But I'm strange." The two bosses are both big businessmen who made a fortune in Fukagawa. Why do you fancy the business of pulling cement and fertilizer from the countryside? ”

Zhao Yuemin and Hu Dong glanced at each other, and both of them smiled.

"Actually, our purpose is not just to pull cement in the countryside." Zhao Yuemin explained, "Our company has opened a logistics company in Shenchuan, specializing in customs declaration for export goods. However, customs declaration is also a part of transportation. We haven't made any profits in other links. We want to seize the inland waterway shipping market first, and then integrate the logistics supply chain in the future. ”
