Numerical Study on Type Comparison of Submarine Cable Landing Floating Airbag

During the submarine cable landing construction, the floating airbag is the key to ensuring that the submarine cable itself is not damaged due to increased stress. Aiming at the existing various types of floating airbags, using the method of numerical simulation, the system optimization research and analysis are carried out from the comparison of the force of different types of floating airbags. It is found that the floating pillow is beneficial to reduce the lateral force of the current on the floating airbags and the submarine cable.
