Jiaolong Underwater Engineering Co., Ltd. dares to integrate潜水 technology development, research, and practice into a comprehensive service. The company has increased its investment and added imported diving equipment. Our main business scope includes: troubleshooting underwater issues in various vessels; underwater cutting, salvage, welding, leak plugging, underwater bricklaying and sealing walls, underwater inspections, propeller and other underwater cleaning services; various underwater installation and removal services; as well as underwater exploration and inspection in rivers, lakes, and reservoirs, underwater construction projects such as reservoirs, power stations, water purification plants, bridges, underwater pipeline laying and backfilling, and underwater detection and camera operations.
Construction Schedule and Safety Measures
1. Pre-job briefing for underground operations, including well depth, entry depth, water level difference at both block points, water depth, and current conditions, and clearly defining the operational objectives and specific technical requirements for construction.
Divers must be certified to operate, equipment must be properly adjusted, and divers' physical signs must be normal. Ensure that the equipment is in good working order, communication is functioning, and the divers' physical condition is normal prior to entering the well.
3. Rescue equipment and personnel preparation. In addition to the normal personnel and equipment for well operations, a separate set of rescue equipment and personnel must be provided to prevent any accidents during operations and ensure preparedness for rescue.
4. Underground Operations, ground crew in place. Compressor Maintenance Staff: Ensure the compressor runs smoothly before the divers descend and until they surface, report any issues to the communications officer immediately; Ground Maintenance Staff: Responsible for coordinating with all personnel to meet the demands expressed underground; Communications Staff: Communicate with underground workers, understand their working conditions and needs, and be aware of the safety status at each work site.
5. This task primarily involves cutting and clearing pipes, followed by cleaning debris and then constructing walls. Before building, due to a water level difference on both sides, divers will enter the water only after the flow has evened out and no significant water currents are present. Due to the gases and water underground, special requirements are placed on the equipment used, so we employ pneumatic, hydraulic, and low-pressure equipment underground.
6. Hoisting personnel must follow the instructions of the communication personnel while also being attentive to the conditions underground. Absolutely no hoisting is allowed when there is someone at the wellhead. Prior to each hoisting, signal the diver to confirm their safe position. Place the hoisting item aside for confirmation by Party A.
7. Decontamination work, after completion of construction, conduct a safety confirmation on the construction area and wellhead, primarily ensuring the wellhead cover is secure.
8. In the event of serious injuries, deaths, or other safety accidents, Party B shall immediately report to the relevant authorities (110) and notify Party A, while also handling the matter as required by the relevant departments. To ensure timely rescue, familiarize yourself with and remember the contact information of nearby hospitals and route maps.
Party B shall comply with the relevant management systems for safety production in engineering construction, strictly organize construction in accordance with safety standards, and take necessary safety protection measures.
Mega Dragon Diving Supplies provides breathing gases for divers, which should comply with the following regulations: The air supply for divers, the scheduling of work and rest times for divers, and the diving team's operation should be calculated at a pressure of not less than 8 cubic meters per minute under normal pressure to ensure the safety of divers during diving operations and the smooth implementation of diving work. The construction period guarantee measures of the diving company aim to deliver excellent underwater operations to the owner, which is our company's pursuit and goal. During the project, we adhere to the philosophy of "careful construction, strict contract compliance, and reputation" and the target of "unit project fulfillment rate" to carefully carry out construction to ensure the implementation of the work schedule as planned. Salvage and rescue is a relatively complex underwater operation that requires close cooperation between salvage teams. Every step must be taken with seriousness, meticulousness, strictness, and safety. As long as each salvage team member works together, all salvage services can be successfully completed. The salvage team must first ensure the personal safety of each member and minimize potential dangers.
Our technical staff provides a detailed explanation. The staff indicates that objects typically recovered underwater are sunken ships or heavy cargo, with the main preparatory steps including: underwater exploration, which is a crucial step before lifting, requiring divers to thoroughly record underwater construction conditions, including water flow rate and temperature. Additionally, carefully inspect and mark the areas where the lifting lines can be secured. After a detailed exploration, calculate the weight of the lifting vessel and the specifications of the lifting equipment based on the weight of the object and underwater stress conditions. Secure the lifting lines at pre-marked locations and check their stability. Reconfirm the lifting vessel's lifting capacity and conditions, and have them checked and confirmed by relevant responsible parties. The working environment should be secured before lifting, taking into account the current wind, direction, wave height, and weather conditions. With extensive experience in underwater operations across industries like water plants, shipping, water conservancy, port, bridges, and municipal pipelines, Longqiang Company can meet your needs. We can arrive at the underwater construction site on the day of the call and provide a precise underwater construction plan and a quote for the diving operations.
