Divers must not operate in unstable underwater environments. Prior to diving, it must be clearly established what the water depth is, the nature of the work, and the diving procedures. Divers must be properly and securely dressed; do not substitute signal lines for harnesses. When divers are descending or ascending, separate the air supply hoses, signal lines, and descent guide lines. After the diver reaches the designated depth, the diving helmet should be ventilated for 2-3 minutes, and the air supply hose and signal line positions should be arranged before starting work. Communication between the surface and underwater must be concise and definite, without omitting the subject. When adjusting the air supply using the waist valve, the air flow should be slowly regulated according to the descent or ascent rate. Equipment for deep water diving operations must undergo rigorous inspections and multiple adjustments to ensure their functionality before use. Personnel using imported diving equipment should be familiar with the equipment's performance, understand how to use it flexibly, and be aware of safety precautions. Huahang Submarine Engineering Co., Ltd. is "established on precision and holds comprehensive qualifications." The basic operation process for underwater shipwreck recovery includes gathering information and conducting scans. We must clarify beforehand that no company or individual can guarantee successful recovery. However, please rest assured that legitimate recovery teams are严谨 and fact-based, will not engage in any illegal activities, and possess precision underwater search sonars. These sonars use sound waves to detect and search for underwater objects, individuals, 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 required to ensure proper operation upon performance compliance.
Divers report their daily conditions to the dive leader before entering the water.
Dive Team Responsibility System, a work log must be filled out for each shift.
Two diving teams must check the ropes and air hoses at all times during the same construction to prevent entanglement.
Strictly control the working hours and cycles of divers to ensure they receive adequate rest.
No scuba divers allowed for underwater work.
Ensure technical briefing, everyone signs in.
Diving operations are strictly conducted in accordance with diving operational procedures.
Adhere strictly to operational procedures, display warning signs for civil construction, and create a strong atmosphere.
Under the condition of ensuring smooth communication, when using the accompanying rope, the specific process is (tighten once, loosen twice, and land on shore).

The administrative person in charge of the project is Da Hai. Full pipeline installation. Load-bearing wall door openings/drilling services, to meet more clients and property owners. Before the recovery operation, an application for a navigation notice must be submitted according to the Navigation Traffic Law. When carrying out recovery operations, the recovery operator must ensure that there are no reinforcing bars inside the sea. If holes are drilled at the top or bottom, it will damage the reinforcing structure of the beam, leading to a reduction in the building's structural integrity. Divers should wear diving knives for underwater operations, and they should be equipped in deep water operations as much as possible. Regarding the requirements for concrete cutting dimensions, this is also a concern for many consumers. Only on this basis. Our service scope covers, mainly business operations. Underwater services welcome cooperation. Firstly, we need to understand what underwater operations include. Underwater recovery includes the recovery of sunken ships and underwater objects.
