... efficiency and reduces emissions. Provided the measurement technique can offer insights into levels of solids, emulsion, and foam layers, non-intrusive level measurement could potentially become an enabling technology for additional extensions of asset lifetime. This is because a non-intrusive profiler would...

... and subseabed soil properties and structure, and detect all objects that may prove hazardous to pipeline installation and operation. Survey data are collected by a variety of sensors: multibeam and sidescan sonars, magnetometers and subbottom profilers. In environments where UXO may be present, these sensors...

... required for seismic risk analysis. In order to achieve these objectives, a high-resolution multibeam echosounder, side scan sonar and Chirp sub-bottom profiler was mounted on an ROV to reduce the water column height between the sensors and the seabed. This resulted in increased data accuracy...

... Abstract A towed multi-channel FM acoustic reflection profiler has been developed for locating and generating images of buried objects. One significant application of this sonar is buried pipeline surveying. The multi-channel reflection profiler uses 16 line arrays mounted in a towed vehicle...

... ABSTRACT Sub-bottom profiling in South Africa has, in the past, been used as a general mapping tool in deep water. Recently the shift has been towards shallow water engineering and mining applications within the costal zone where existing profiling systems fail to operate successfully...

... proposed pipeline route was changed and the length of flexible pipe was increased. Geophysical survey tools included: a narrow-beam water-depth recording system with velocipede calibration; a scale-corrected side-scan sonar system; a 3.5-kHz shallow-penetration profiler; a one-kilojoules intermediate...
