“…A wave glider is an unmanned vehicle that combines two bodies (floater and submerged glider) via flexible umbilical cables, which can directly convert the movement of ocean waves into propulsion, and also overcome the need for low energy consumption during the observation period at sea. (Zhang et al, 2020). Wave gliders have been widely researched and published by papers, among others (Olson, 2012) which examines the working principle of the sensors used in wave gliders.…”

Indonesia as a country that often experiences tsunami disasters needs to have an early warning system against tsunami disasters. This system can use various existing technologies, one of which is the tsunami buoy system. The new tsunami buoy system does not use the natural mooring system but uses the wave glider system. This paper discusses the structural strength of the surface floater of wave glider using Eva Foam and Fiberglass material for skin and Alluminium material for frame and kell. The surface floater using 16 pieces for frame and 1 piece for keel. Enviromental loads is use in this paper like hydrodynamics load and weight load. The results from this paper is material from Eva Foam has a maximum principle stress is 12693 Pa and shear stress is 6114.6 Pa. For material from Fiberglass has maximum principle stress is 11.875 Pa and shear stress is 6076.3 Pa. Safety factor (SF) from maximum principle stress and shear stress for Eva Foams is up to 6x and SF for maximum principle and shear stress for Fiberglass is up to 26x. Conclusions for this paper is the desain for surface floater of wave glider it can be operated in the sea with draugh 0.18 m.

“…In addition, the materials selected for the acoustic release device also need to have good process performance and be easy to process into the required parts. According to the properties of various metal materials, the materials used in the acoustic releaser mainly include aluminum alloy, stainless steel 304, engineering plastics and high strength alloy steel [4][5]. Table 1 is a comparison table of mechanical properties of different materials.…”

In this paper, the structure and basic working principle of acoustic releaser are introduced. The main structure of the acoustic release is designed, including material selection, pressure shell design, release mechanism design, etc., and the stability check and finite element simulation analysis are carried out. Effectively improve the stability and reliability of acoustic release. It is of great significance to improve the acoustic releaser technology level, meet the needs of Marine investigation and promote the development of Marine monitoring technology in our country.
