Divers must not operate in unstable underwater environments prone to collapse. Prior to diving, it is essential to clearly determine the water depth, job content, and underwater operation methods. Divers must wear proper and secure gear; signal lines must not replace safety belts. When descending or ascending, the air supply hose, signal line, and descent guide line 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 line should be arranged properly. Communication between the surface and underwater should be concise, definite, and include the subject. When adjusting the air supply using the waist-mounted regulator, the gas flow should be slowly adjusted according to the rate of descent or ascent. Equipment for deep-water diving operations must undergo rigorous inspection and multiple successful adjustments before use. Operators of imported diving equipment must understand the equipment's performance, master its flexible use, and be aware of precautions. Huahang Underwater Engineering Co., Ltd., "Established with Excellence, Fully Certified." The basic operation process for underwater shipwreck recovery: gather information and conduct scans. We would like to clarify in advance that no company or individual can guarantee successful recovery, but please be assured that our professional recovery teams are rigorous and honest, and will not engage in any illegal activities. The recovery teams possess precision underwater search sonar, which uses sound waves to detect and search underwater objects, people, ships, vehicles, and riverbeds.
Measures for diving operations:
Diving construction operations must be conducted in accordance with the regulations of the Underwater Diving and Salvage Association.
Diving construction operations must adhere to the principles of prevention first, rigorous organization, and legal compliance to ensure the personal health of divers.
Perform regular equipment inspections to ensure compliance with operational specifications.
Divers report their daily conditions to the dive leader before entering the water.
Dive Team Responsibility System, work logs must be filled out for each shift.
Two diving teams must continuously check the ropes and air hoses during the same construction work to prevent entanglement.
Strictly control the working hours and cycles of divers to ensure they receive adequate rest.
Prohibited for non-divers to perform underwater operations.
Ensure technical briefings are conducted, and everyone signs in.
Diving operations are conducted strictly 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, use in conjunction with a rope, specifically as (tighten once, loosen twice, land thrice).
