Parachute Air Lift Bags with Underwater Open Bottom for Underwater Geotechnical Surveys
Description
Marine debris poses a significant environmental threat, and buoyancy bags are often used for its removal from oceans, rivers, and harbors. These bags can lift large pieces of debris such as sunken boats, containers, and abandoned equipment. Made from tough, durable materials, buoyancy bags are designed to withstand harsh marine conditions while providing high lifting capacity. By using these bags, environmental agencies and marine conservation groups can quickly and safely remove debris from underwater environments, helping to preserve the health of aquatic ecosystems.

FAQ
1. Do Buoyancy Bags need to be anchored?
In most cases, Buoyancy Bags are not anchored but are instead attached to the object being lifted with ropes or cables. However, for certain operations, they may require some form of anchoring or stabilization.
2. Can Buoyancy Bags lift underwater vehicles?
Yes, Buoyancy Bags are ideal for lifting submerged vehicles, such as underwater drones or small boats. They provide the necessary buoyancy to safely raise the vehicle to the surface or move it to another location.
3. Can Buoyancy Bags be used in both freshwater and saltwater?
Yes, Buoyancy Bags are designed for use in both freshwater and saltwater environments. They are resistant to corrosion and damage caused by exposure to saltwater, ensuring long-term performance.
4. Can Buoyancy Bags be used for lifting vehicles in dry docks?
Yes, Buoyancy Bags are used in dry docks to assist with lifting and repositioning vehicles or ships. They provide an efficient alternative to cranes and other heavy lifting equipment in these environments.
