UNDERWATER NAVIGATION
Single-point current meter designed for very long-term deployments
With all the features and capabilities of the standard Aquadopp, the deepwater Aquadopp 3000 m current meter has been used and proven by oceanographers around the world for almost 20 years. Thanks to innovative data diagnostic features for challenging environments, it provides exceptionally high-quality 3D currents in a form factor that is easy to install in any type of mooring line configuration, or simply attached to a bottom or surface platform.
Introducing the all-new, extremely compact and high-resolution multibeam sonar from NORBIT.
The WBMS-series are ultra compact sonars designed specifically for use on all platforms. With low power consumption, the system may be operated for a full day on a single battery. NORBIT’s wideband multibeam technology allows long range real-time data collection, whilst simultaneously achieving high range resolution.
Neptune Oceanographics’ unique SNIFFIT system for the detection of subsea leaks of hydrocarbons is a proven, real time, in situ method that has been used world-wide and has many applications in diverse underwater markets.
The small, lightweight detector combines with its control unit and Windows based software to warn the user of the presence of gaseous Hydrocarbons (such as methane) ahead of the more obvious physical clues such as the presence of bubbles.
The Sniffit was developed specifically to allow, real time in situ detection of dissolved and gaseous methane in water, whatever the source, and has been successful in hydrocarbon surveys to depths of over 3000m world-wide.
Following on from the very successful MKI and MKII versions of the ‘Long Ranger’ family of subsea leak detection systems, Neptune have released their latest MKIII version.
As with the earlier versions, the MKIII can detect fluorescent dyes, crude oils, lubricating oils and hydrocarbon based control fluids at depths down to 3000m (6000m as special) but with enhanced performance.
Under some circumstances such as with water injection flow lines, leaks can be identified using the temperature difference between the surrounding seawater and the water leaking from the flowline.
The flowline water temperature is normally above ambient seawater temperature due to the high pressure pumping required.
Neptune has developed a differential temperature technique that can detect very small temperature changes. The sensors comprise fast, high precision thermistors connected through the Neptune leak detection system to the ROV umbilical for onboard display and recording.
