CHAPTER 509: CHAPTER 357: THE PERSON MAY BE FAKE!

Sister sought to win people over with virtue, Han Yu could only dream of such luck.

Considering it would be awkward for her to encounter people, he skipped the meal at the Transportation Bureau, briefed Chen Zikun, Zhang Ping, and Captain Fan, greeted Commissioner Ding and Director Chu, then gathered a stack of materials and drove to Binjiang to report to the bureau leadership.

Commissioner Ding clearly understood that the young man’s leaving was not only because he was worried about Jiang Meimei feeling awkward, but more so because he did not want to host the leaders. This traditional reluctance was something he shared with his mentor.

Han Yu didn’t know what the Old Political Commissar thought, but he arrived at the Water Police Station during mealtime, had a quick meal in the canteen, and then at the suggestion of Political Commissioner Jiang, went to a small meeting room on the second floor to report the slimmed-down construction plan based on the initial expert validation.

"The main engine definitely cannot be a Caterpillar from the United States; it must be domestically produced."

"Salted Fish, the main engine is not like other equipment; I’ve looked into it, and the imported main engines truly have better quality than the domestic ones."

"Director He, I also know that the imported ones are better, but we can only do so much with the money we have."

"What if it malfunctions while in use?"

"We have been using the domestically produced 6135 model in batches since the 1950s, and now the quality of domestic diesel engines has improved a lot. Proper maintenance should prevent problems. Besides, East Sea Diesel Engine Factory is currently introducing foreign technology and planning to form a joint venture with foreign engine manufacturers."

The young man was also trying to save money.

After some thought, Director He smiled and said, "You are the expert in this field, and you will be the one using the new ship, so if you think the domestic engine will work, let’s go with that."

"Thank you, Director He."

Han Yu handed over a previously validated expert plan and continued, "Regarding the propulsion system, I also know that fully azimuth thrusters are better. But their cost is too high; we can’t afford them, so dual rudder and dual propellers are more realistic."

Director He, looking at the plan materials, asked, "Do we need bow thrusters on both sides of the bow?"

"No, they’re too expensive."

"And the speed?"

"The maximum speed of cargo ships on the Yangtze River cannot exceed 15 knots, newly built fishing boats can reach 20 knots in good sea conditions. Our new ship, besides performing firefighting and rescue tasks, will also enforce the law on the water, so logically the maximum speed should be at least 16 knots, otherwise, we won’t be able to catch up."

Han Yu took a small sip of water and said helplessly, "Although there’s only a one-knot difference between 15 knots and 16 knots, the cost to increase that one knot is not trivial, so our maximum speed can only be designed at 15 knots."

Political Commissioner Jiang smiled and asked, "What if, during water law enforcement, the suspect’s vessel speeds over 15 knots and we can’t catch up?"

Director He looked up and said, "Indeed, those vessels trying to escape won’t care about maximum speed. They will maximize their horsepower and flee at the highest possible speed to escape the crime. I have to consider this."

"If a suspect’s vessel really pushes its engine to the limit and tries to escape desperately, our new ship, even if it can reach 15 knots, won’t be able to catch up."

Han Yu pulled out a sketch he had drawn, lifted it up, and said with a smile, "The new ship has more power than 001, and it’s also heavier; I estimate it can reach 300 tons. There will be enough space on the aft deck to install a crane, and we can buy two speedboats according to the space dimensions of the aft deck.

If we encounter a boat trying to escape, we’ll use the crane to deploy a speedboat to pursue. No matter how fast the suspect’s vessel is, it cannot outrun the speedboats donated to the Water Police Station and Port Supervision Bureau by Linghai Shipyard. Once we target them, they definitely won’t be able to escape."

Using the Law Enforcement Rescue Boat as a mothership, this idea is interesting.

Director He thought it was feasible and nodded slightly with a smile.

Having spent decades by the river, Political Commissioner Jiang was too familiar with the conditions on the river and reminded, "Salted Fish, catching up doesn’t mean you can get close, nor does it imply that you can board."

"I know, chasing large ships is very dangerous."

Han Yu smiled confidently and said, "That’s why I just mentioned deploying one speedboat in such scenarios, not two."

Political Commissioner Jiang subconsciously asked, "What do you mean?"

"Speedboats have very small fuel tanks and limited endurance, so they should be deployed one after another, taking turns to pursue. Back when we jointly went to Jiangyin Waters to arrest robbers who attacked ship crews, speedboats and motorboats mainly played a monitoring role. Climbing aboard was ultimately achieved using 001 and the Supervision Boat."

"I understand now, the role of speedboats is not to assault but mainly to track and monitor."

Concluding the reports item by item, the overarching idea was to save wherever possible.

The report moved on to firefighting systems; domestic firefighting equipment is severely lagging, not only in water firefighting equipment but even more so in land-based firefighting equipment.

In recent years, virtually all firefighting engines purchased by various regions’ fire services are imported.

Even the cheapest extendable ladder type of aerial firefighting vehicles costs over two million yuan, and the ladders can only extend up to seventeen or eighteen meters.

"Fire pumps can only be imported. There are few professional fire and rescue boats domestically, while there are many in foreign ports. Just like the experts said during the validation, most use pumps by Dutch company Nijhuis with a flow rate that can reach up to nineteen hundred cubic meters per hour..."

"Director He, the experts during the validation mentioned that this hydraulic lift system is very necessary."

"How does it lift?"

"Compared to large-tonnage roll-on-roll-off ships, bulk carriers, and oil tankers, our new ship is just slightly larger, its main-ship barely reaches their deck height, not to mention the decks which have ship structures as high as five to six stories. If a fire breaks out on the deck, our water cannons can only spray upwards."
