Chapter 38: Chapter 35: Little Tech Expert_2

Xu Sanye turned his head to look at Director Yang and Director Shen, then looked around at everyone: "Next, please have Master Zhou from Bailong Port Shipyard present the design proposal. Director Liu, we don’t really understand, please help us oversee it, and if there are any deficiencies or aspects that are not comprehensive, please point them out to us."

"Okay."

"Old Ding, Old Shen, Xiao Zhang, regarding issues related to the budget, please also raise them timely. The deadline is tight; time waits for no one. Both the proposal and the budget must be finalized tonight."

Xu Sanye, originally speaking with emphasis and full of spirit, suddenly noticed that wall grass, Housekeeper Shen, and Zhang Lan were all unconsciously looking at Director Yang. He instantly felt embarrassed, and could only turn back to ask, "Director Yang, is this arrangement okay?"

Director Yang cleared his throat and said slowly, "Let’s begin."

"Okay, Master Zhou, begin."

This is at the Police Bureau!

Master Zhou had never experienced such a situation; his hands holding a large roll of technical drawings were trembling, and for a moment, he didn’t know how to start.

During this critical moment, as problems arose, Manager Wu became anxious. Not being very knowledgeable about technical aspects and seeing Salted Fish also worrying for Master Zhou, he suggested in a hurry, "Leaders, our Master Zhou only knows how to work hard without much talking. How about letting Xiao Han help with the report?"

Xu Sanye was already feeling embarrassed and now even more so. After all, he was the one who found this party B, and said unhappily, "These are your design drawings!"

"Xiao Han also participated in the design, he helped with several drawings."

"Is that so?"

"Really, if you don’t believe it, you can ask Xiao Han."

There’s an important course in marine engineering technology called mechanical drafting.

He had to take a self-study exam soon, and while other subjects could be learned on one’s own, mechanical drafting can’t just be learned through self-study.

Seeing Master Zhou busy with the drawings these days, Han Yu naturally wouldn’t miss the opportunity to learn and went to the shipyard office to watch Master Zhou draw every noon and evening.

At first, he just watched and asked questions, later helping with the drawing; he could be considered as having participated in the design.

Just as he was unsure how to begin, Master Zhou felt like he had found a savior and eagerly said, "Xiao Han, please help, report for us, I’ll present the drawings."

The embarrassment couldn’t go on any longer, the scene couldn’t stay cold.

With no other option, Xu Sanye grimly said, "Xiao Han, step up, make it quick."

"Yes!"

Han Yu never expected to stand in for Master Zhou, but he steeled himself and stepped forward to face everyone.

Glancing back at the first drawing displayed by Master Zhou, recalling the things Master Zhou had said while drafting, he took several deep breaths, adjusted his emotions, and nervously started to report.

"Leaders, this is a design proposal based on the requirements Director Xu proposed after inspecting the four dunships of the relevant law enforcement departments, in accordance with national standards.

The project involves the construction of a floating pier for docking a hundred-ton class law enforcement ship, divided into six parts. Let me first report to the leaders about the main project, which is the design proposal for the dunship. The dunship is thirty-three meters long, eleven meters wide, with a design draft of one and a half meters.

The main hull is divided into several sections by five transverse bulkheads and a mid-longitudinal bulkhead. The bow and stern are for the anchor chain room; other than the pump room and storeroom, all other compartments are empty. According to the ship’s draft and buoyancy state, appropriate fixed ballast is placed in each empty compartment..."

He spoke fluently and sounded very professional.

Xu Sanye felt he regained some face, showing a smile.

Director Yang, Director Shen, and Instructor Ding were surprised and showed an astonished expression.

Zhang Lan had known Little Salted Fish understood technology and could repair machines, but didn’t expect he would articulate so well; she secretly gave a thumbs-up.

Presenting a design proposal... Now with Master Zhou constantly pointing out relevant locations and data on the drawings, Han Yu not only didn’t feel nervous but also slowly got into the groove.

"In terms of structure and materials, the ship is made of steel, with a single deck and single bottom. The main hull is longitudinally framed; the deck housed transversely framed. From bow to stern at the 8-number, 24-number, 40-number, 56-number, and 72-number marking positions, which are the ones my finger is pointing at, there are five watertight transverse bulkheads."

"In the middle of the ship, from here to here, a mid-longitudinal bulkhead is the set that runs through the bow and stern; the outer hull and end enclosure plates are made of eight-millimeter thick steel plates. The main deck is seven millimeters, the bulkhead plate is six millimeters, and the exterior walls of the deck housing are also made of six-millimeter thick steel plates..."

Director Yang, Director Shen, and Instructor Ding were initially surprised, but as they listened on, that turned into astonishment.

This was not just an immobile iron shell on the river; it was essentially a nearly hundred-ton vessel, just without an engine. It had everything else a ship should have.

At the bow and stern, there were six large anchors, with one anchor weighing up to five tons!

Several anchor windlasses would need to be installed, as well as various steel brake pawls for chains, simple anchor discarding devices, horizontal guide rollers, and cable winders...

The ship’s building structure would use lightweight steel framing; the walls made of steel plates lined with fifty millimeters of fireproof and thermally insulating rock wool, with nine-millimeter boards as the substructure.

The engineering department would include a pump room and bilge water, as well as a firefighting system.

The electrical department would have several switch cabinets to connect to three hundred eighty volts of three-phase electricity, and the installation of what a signal lamp control panel, a broadcasting and general alarm board, and a ship-wide comprehensive alarm board around what lighting, navigation, and signal systems.

"Xiao Han, let me interrupt for a second."

"Instructor, please."

"Why do we need all these systems for a dunship that will remain stationary on the river?"

"Master Zhou designed this according to national standards for ship manufacturing, and the Yangtze River North Branch Channel is always silted up. At its worst, it could accumulate over a meter of mud overnight.

This type of incident is not unprecedented, it happened last year in Bailong Port waterway, where so many passenger ships were stranded that not a single one could move."
