Marine industries rely heavily on various pieces of equipment for different operations. Without this equipment, marine operations would not be possible. Among these pieces of equipment, marine airbags are one of the most important products. How many applications do marine airbags have? This question is the most confusing problem, especially for newbies in the marine industry.
Marine airbags are valuable equipment used in various marine operations. These include ship launching, ship recovery, and the list goes on. Their load-bearing capacity and durability make them stand out. Without them, ships or vessels may not be able to go into the water safely. In this article, I will discuss different applications of marine airbags.
Overview of Marine Airbags
Before discussing the applications, let’s first understand the basics of marine airbags.
마린 에어백 are equipment used to lift and move large ships and vessels. They are cylindrical and inflated during use. They are made from tyre cord fabric and rubber materials. These materials give these marine airbags both elasticity and strength. They have excellent load distribution, which makes them withstand extreme loads efficiently.
Have you ever thought about how ships and vessels enter the ocean? As you know, modern ships are very large and have high load capacity. Do the large cranes carry them and put them into the ocean? No. Ships and large vessels are launched using airbags, which help them move despite their very high weight. Marine airbags are made of rubber and synthetic tyre cord fabrics.
They are cylindrical and very elastic. During use, these marine airbags are placed underneath the ship or vessels. They are inflated using compressed air. As air enters, these airbags inflate, lifting the ship upward. Once inflated, these airbags propel the ship forward as they orient themselves toward the ship’s direction of travel.
There are multiple airbags placed one after another. This series of airbags makes the vessel enter the water easily. Not just in ship launching, these airbags are used in ship recovery and many other marine operations. These marine airbags consist of multiple layers, which enable them to withstand stress. Their elastic material allows them to absorb the impact force and distribute it evenly across the surface.
Applications of Marine Airbags
How many applications do marine airbags have? There is no exact number of applications for marine airbags. This equipment is used in a wide range of conditions. These include ship launching, ship recovery, ship lifting, marine salvage, and more. This equipment even helps lift large heavy-duty vessels.
In the section below, I will explain the most common application of marine airbags.
1- Ship Launching
Ship launching is one of the standout applications of marine airbags. Without them, launching a large ship would be very challenging. In this process, multiple 선박 발사 에어백 are positioned beneath the ship’s hull. After that, the airbags are inflated with compressed air, lifting the ship slightly.
These airbags roll and move, lifting the ship despite its greater weight. These airbags make the ship move towards the water and sink into it. It is worth noting that airbags are very elastic. So they absorb the force when the ship moves forwards on these airbags and enters the water. Using marine airbags for vessel launching is also cost-effective.
2- Ship Landing (Hauling Out)
Even large ships can face mechanical problems. In some cases, these issues are fixed while the ship stays in the water. However, if the issue is more critical, ships are brought ashore to have their issues fixed. Bringing large ships on land can be challenging. However, the use of marine airbags makes ship landing a lot easier.
During ship landing, a series of marine airbags are placed under the hull of the ship when it comes to shore. Once these airbags are inflated, they slightly lift the ship. After that, these airbags roll so that the ship that comes out of the water reaches the land. In this method, there is no need to pull the ship. Instead, the ship’s rolling provides support and helps it come out of the water.
3- Marine Salvage and Wreck Recovery
Salvage teams rely heavily on these marine airbags when they recover any sunken ship or its wreck. As you know, accidents in the ocean are not the rarest. A ship or vessel can sink during an accident, while the crew are generally saved first. However, salvage operations are then carried out to recover the sunken ship or its wreck.
In this process, salvage teams use the airbags to recover the sunken ship. How? In this process, divers first connect multiple airbags to the sunken ship. After that, the 해양 구조 에어백 are inflated under very controlled conditions. When these airbags inflate, they provide buoyancy to the sunken ship. As a result, the ship comes to the surface due to the buoyancy provided by the airbags. This is also done with wrecks if the ship is severely damaged.
4- Used in Dock and Harbour Construction
Construction of docks and harbours is a challenging process. Why? The reason is that different components make these docks. These include concrete blocks, caissons, prefabricated sections and the list goes on. Transporting these components to the site can be a huge problem. That’s where the marine airbags prove to be a great help.
In this process, these airbags are placed under the dock components and then inflated. As a result, these airbags lift the components and move them forward through rolling. This way, the component, irrespective of its size or weight, reaches the site easily. You won’t have to use cranes or any other lifting mechanism to transport the deck section on site during construction.
5- Temporary Floating Structures
Using temporary floating structures is common. The best examples of such structures include floating bridges, work platforms, and so on. Without building fixed platforms, the floating structure offers an affordable way to get things done. These floating structures are supported by marine airbags, allowing them to float on the water’s surface.
The marine airbags are connected to the floating structures from all sides. Additionally, the airbags are also positioned underneath the structures. This ensures the structure remains afloat and stable in its position. Remember, using an airbag to keep the structure afloat is highly cost-effective, making it a practical option.
6- Used For Heavy Lifting And Moving
Marine heavy lifting airbags are widely used to move various heavy objects. Lifting and moving such large parts is not easy through any other method. These parts can be any storage tanks, ship parts, or any other object. Remember, marine airbags can do it for two primary reasons. First, these airbags can withstand extreme loads with ease because they distribute the stress evenly.
Secondly, they can roll even when under extreme load. That’s why these airbags are positioned underneath the objects. As they inflate, they carry the object upwards. After that, these airbags (multiple) roll and make the heavy-duty objects move forwards. This means the transfer of objects happens without the use of any cranes or other lifting machines.
7- Emergency Rescue Operations
Despite care, accidents are inevitable in the marine industry. Not only in the marine sector, but you might also have heard instances where vehicles get drowned in floods. Under such conditions, marine airbags are highly effective at protecting assets. These airbags are placed under the vehicle or anything you’re saving.
After that, the airbags inflate, providing buoyancy to the vehicle. This way, the vehicle stays afloat on the surface rather than going deep. What makes these airbags the best option for rescue operations is their easy deployment. They can be deployed in minutes, if not seconds, and save the submerged objects. This means marine airbags are useful not only for the ocean but also in flood conditions.
자주 묻는 질문
What types of vessels can be launched using marine airbags?
All small and medium ships can be launched using marine airbags. For larger vessels, you’ll need larger airbags and vice versa. Additionally, you can also use them to launch barges, fishing boats and so on.
Can marine airbags be reused?
Yes. Marine airbags are made of strong, flexible material. They remain in good condition even when exposed to extreme load and stress. So they can be used repeatedly with ease. That’s the main reason these airbags are cost-effective in the long run.
Is a single marine airbag enough for ship launching?
No. Multiple airbags are used for ship launching. These marine airbags are positioned in series and roll to propel ships into the water. Using single airbags does not make sense for ship launching.
결론
Marine airbags have become one of the most important pieces of equipment used in different marine operations. They are cylindrical and very robust, capable of withstanding loads and stress. Interestingly, the marine airbags are available in different sizes. Small airbags are preferred for small ships and boats.
In contrast, larger airbags are the best option for larger ships and vessels. As I mentioned above, launching or landing a ship can be very difficult without these airbags. In this article, I have discussed various applications of marine airbags. They are highly versatile, offering a wide range of applications. From ship launching to moving heavy objects, these airbags stand out everywhere.
