Robust and field-proven acoustic releases
Oceano - Construction

Vue d'ensemble

Leveraging 40 years of experience and with over 15,000 units delivered, iXblue’s acoustic releases have proven their reliability by meeting the most demanding needs of scientific campaigns and offshore works.

Strength, accuracy, long-battery life (up to 10 years) and a permanent concern for quality make iXblue's Oceano acoustic releases a state-of-the-art product range designed for payloads from 200 kg to 5,000 kg and dedicated to both coastal and ultra-deep offshore operations.


New acoustic release: Oceano R5

Oceano R5

Oceano R5 is the latest addition of iXblue’s oceanographic acoustic releases. It has been designed to be a real workhorse: based upon what made the success of the previous Oceano 2500S Universal (AR861B2S), robustness and reliability, Oceano R5 is lighter and shorter for the same depth rating (6,000m/19,700ft). It is equipped with a positive drive-off release mechanism for improved release reliability and built out of high-tensile strength super duplex stainless steel offering outstanding corrosion resistance. Fitted with new electronics, Oceano R5 was designed to minimize mechanical friction for added robustness.
