Divers must not operate in underwater environments prone to collapse. It is mandatory to clearly determine water depth, job content, and underwater operation methods before diving. Divers must wear proper and secure gear; signal ropes must not substitute for safety belts. When descending or ascending, the air supply hose, signal rope, and descent guide rope must be kept separate. After reaching the designated depth, the diver's helmet should be ventilated for 2-3 minutes before starting work, and the air supply hose and signal rope should be properly arranged. Communication between the surface and underwater should be concise, affirmative, and avoid omitting the subject. When adjusting the air supply using the waist-mounted valve, the air supply volume should be slowly adjusted according to the descent or ascent rate. Equipment for deep-sea diving operations must undergo rigorous inspection and multiple successful adjustments before use. Operators of imported diving equipment must be familiar with the equipment's performance, learn to use it flexibly, and be aware of precautions. Huahang Underwater Engineering Co., Ltd., "Established with Excellence, Fully Certified." The basic operational process for underwater shipwreck recovery includes gathering information and conducting surveys. We would like to preface that no company or individual can guarantee successful recovery, but please rest assured that professional recovery teams are meticulous, factual, and will not engage in any illegal activities. Recovery teams possess precision underwater search sonar, which uses sound waves to detect and search underwater objects, people, vessels, vehicles, and riverbeds.
Measures for Diving Operations:
Diving construction operations must be conducted in accordance with the regulations of the Diving Salvage Industry Association.
Diving construction operations must adhere to the principles of prevention-first, rigorous organization, and legal compliance to ensure the personal health of divers.
Regular equipment inspections are required to ensure compliance with performance specifications before operation.
Divers report the day's conditions to the dive leader before entering the water.
Diving Team Responsibility System, work shifts must fill out (work log)
Two dive teams must check the rope and air supply hoses regularly during the same construction work to prevent entanglement.
Strictly control the working hours and cycles of divers to ensure they receive adequate rest.
No non-divers are permitted to perform underwater activities.
Ensure technical briefing, everyone signs in.
Diving operations are conducted strictly in accordance with diving procedures.
Comply strictly with operational procedures, hang warning signs in a civil manner, and create a strong atmosphere.
Under the condition of ensuring smooth communication, the use is in conjunction with a rope, specifically (tighten once, loosen twice, land thrice).

The administrative personnel of the project is Da Hai. The entire pipeline installation. Service for opening doorways in load-bearing walls and drilling holes in walls with water drills. To meet more clients and property owners. Before the recovery operation, an application for a navigation notice must be submitted according to the regulations of maritime traffic law. When the recovery operation is carried out, there must be steel reinforcement inside the sea. If holes are drilled at the top or bottom, it will damage the steel structure of the beam, leading to a decrease in the building's structural integrity. Divers conducting underwater operations should be equipped with diving knives, and this is especially important when working in deep water. What are the requirements for the size of concrete cutting? This is also a concern for many consumers. Only on this basis. Our service scope covers, our main business. Welcome to cooperate for underwater services. Firstly, we need to understand what is included in underwater operations, which includes underwater ship recovery and recovery operations of underwater objects.
