Construction schedule and safety measures
1. Pre-job briefing for underground operations, understand well depth, entry depth, water level difference at both blocking points, water depth, and water flow conditions, clarify the operation objectives and specific technical standards for construction requirements.
2. Divers must be certified and on-site equipment must be properly adjusted. Ensure that the equipment is in good working order, communication is operational, and divers' physical conditions are normal before 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 Personnel: Ensure the air compressor operates normally before divers enter and before they surface, and report any issues immediately to the communication officer; Ground Maintenance Crew: Responsible for coordination among personnel to meet the various demands reflected from underground; Communication Officer: Communicate with underground workers, understand their operational status and needs, and ascertain the safety conditions at each work site underground.
5. This task primarily involves cutting and removing pipes, clearing debris, and then constructing walls. Before building, due to water level differences on both sides, divers will enter the water only after the two sides have equalized and no significant water flow is confirmed. Due to the underground gases and water, special requirements are placed on the equipment used, and 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. Before each hoisting, signal the diver to confirm their safe position. Place the hoisting item to the side for confirmation by Party A.
7. Site Clearance Operations, after completion of construction, conduct safety confirmation on the construction area and wellhead, primarily ensuring the wellhead cover is secure.
8. In the event of major injuries, deaths, or other safety incidents, Party B shall immediately report to the relevant authorities (dial 110) and notify Party A, while also handling the matter in accordance with the requirements of the relevant departments. To ensure timely rescue, familiarize yourself with and remember the phone numbers of nearby hospitals and route maps.
Party B shall comply with the relevant safety production management systems for engineering construction, strictly organize construction according to safety standards, and take necessary safety protection measures.
Mega Dragon Diving Supplies provides breathing gases for divers, which must comply with the following regulations: The air supply for divers, the scheduling of work and rest times for divers, and the retrieval team shall, according to the following regulations, calculate at least 8 liters per minute at atmospheric pressure to ensure the safety of divers during diving operations and the smooth implementation of diving tasks. The construction timeline guarantee measures of the diving company aim to deliver excellent underwater operations to the client, which is our company's pursuit and goal. During the project, we adhere to the policy of "diligent construction, strict contract adherence, and reputation" and the target of "unit project completion rate." We carefully carry out construction to ensure that the work timeline is implemented as planned. Recovery and rescue operations are relatively complex underwater tasks that require close coordination between retrieval teams. Every step must be taken with care, attention to detail, strictness, and safety. As long as each retrieval team member collaborates effectively, all recovery services can be successfully completed. The retrieval team must first ensure the personal safety of each member and minimize potential hazards.
Our technical team provides a detailed explanation. Staff members indicate that objects typically lifted from underwater include sunken ships or heavy cargo. The main preparatory steps include: underwater exploration, which is a crucial step before lifting. The construction unit should assign divers to thoroughly record underwater conditions, such as water flow and temperature. Additionally, carefully inspect and mark the areas where the lifting lines can be securely anchored. After a detailed exploration, calculate the weight of the lifting vessel and specifications of the lifting equipment based on the cargo's weight and underwater force conditions. Secure the lifting lines to the pre-marked locations and check their stability. Reconfirm the lifting vessel's capacity and conditions, and have them rechecked and confirmed by relevant responsible parties. The working environment should be secured, and during the lift, factors like wind, wind direction, wave height, and weather conditions should be considered. With extensive experience in underwater operations across industries such as water plants, shipping, water conservancy, port operations, bridges, and municipal pipelines, Longqiang Company can meet your needs. We can arrive at the underwater construction site on the day of your call, provide a practical underwater construction plan, and offer a quotation for the diving work.
