The Type 8085 Inline XSRS transceiver is the latest addition to Sonardyne's SIPS 2 streamer positioning product range.
SIPS 2 uses a network of acoustic transceivers attached to each streamer, air gun and tailbuoy/ navbuoy to measure ranges between each other and the survey vessel. This enables both the shape of the towed array to be known and the positions of the hydrophones, relative to the survey, to be precisely determined.
Offering the same performance advantages as existing 'clip-on' XSRS transceivers, the new Type 8085 unit is designed to fit in-between streamer sections thus allowing streamers to be deployed and recovered without having to attach or remove any acoustic hardware. This allows for faster and more efficient survey operations whilst improving back-deck health and safety.
Manufactured from Grade 5 Titanium, the Inline XSRS is designed to withstand high operational loads and wrapping onto drums. It has a working load of 30kN and uses industry standard 37 pin Syntrak connectors to connect into the streamer.
Communications and power are picked up from the streamer, whilst all other lines are passed through the unit in a shielded cable bundle. By eliminating the need for an internal battery pack the safety risks and operational downtime associated with replacing batteries, whilst streamers are deployed, is removed.
Like all SIPS 2 XSRS', the Inline XSRS uses Digital Signal Processing with multiple modulation modes to suit different operating conditions. The rugged intelligent transducer array reduces surface and bottom bounce effects using beam steering technology.
