Description
The Marine Airbags
Commonly known as 'rubber airbags', 'MAX airbags','marine air bags', or 'balloons/belons', these inflatable objects are constructed from multiple layers of reinforced rubber. The MAX Marine Airbags are fabricated in accordance with the ISO14409 Ship Launching Air Bags standard. They possess a cylindrical form with hemispherical ends on both sides.
"Ship launching via air bags represents an inventive technique that is purportedly a Chinese invention and has been in application for several decades. The airbags are inflated to hoist the vessel or structure, and then, with the assistance of gravity, it is enabled to glide into the water in a regulated setting. This approach can be readily employed for vessels of all varieties and sizes, and is especially favored for flat bottom barges and small-to-medium-sized vessels."
Advantages
This technology is reputed to be a highly economical solution. With proper maintenance and care, airbags can remain in service for over 8 years. The prices of airbags vary depending on their types and sizes. However, even the larger-sized airbags generally cost less than alternative launching methods.
The airbags offer support to the hull of the vessel and facilitate its movement during launching into the water, additionally safeguarding the hull from damage. According to Kevin, "it is a secure option for launching structures weighing up to 10,000 tonnes". In reality, through meticulous calculation and professional supervision, heavy vessels in China exceeding 50,000 tonnes have also been successfully launched using this technique.
Moreover, in comparison to the oiled slipway launching, which is another prevalent choice for most small to medium vessels, this method is considerably more environmentally friendly. Its adaptability has been a significant factor contributing to its extensive adoption. Over the years, numerous issues such as slipway restrictions and working height difficulties can be resolved without imposing additional costs on shipyards.
Products Introduction
Ship launching Marine Airbags feature an exquisitely designed structure, incorporating five distinct functional membranes within the rubber layers.
Outer Rubber Layer
The outer rubber layer serves as a protective shield on the exterior of the marine airbag. Its primary function is to safeguard the underlying layers from abrasion and various external forces. Composed of a compound with ample tensile and tearing strength, it can endure even the harshest conditions and heavy-duty usage.
Inner Rubber Layer
The inner rubber layer plays a crucial role in sealing the pressurized air within the marine airbags, ensuring airtightness and maintaining the proper inflation state.
Synthetic-Tire-Cord Layer as Reinforcement
The reinforcement cord layers, fabricated from synthetic-tire-cord materials typically utilized in tires, are meticulously arranged at optimal angles. This strategic placement enables them to effectively hold the internal pressure and evenly distribute stress throughout the airbag. As a result, they offer robust and efficient reinforcement, enhancing the overall structural integrity of the marine airbag.
