Marine Meteorology and Oceanography ADCP

Acoustic Doppler Current Profiler (ADCP) carriage, equipped with Teledyne RD Instrument, (vertical transducer). Scientists use this equipment to measure how fast water is passing across an entire water column. An ADCP anchored to the sea floor is used to determine current speed at the bottom of the sea floor, and at equal intervals all the way up to the surface.

The Acoustic Doppler Current Profiler where Decundi inspection personnel witnessed F.A.T of the ADCP shown in the pictures below, is installed on its own structural skid with allied equipment. Some of the allied equipment are noted to be ADCP Carousel, EM Winch motor, Auger Winch and among others but not limited to, a 28” diameter Sheave 78 Series with 1/8” thick urethane lining which are integral for lowering the ADCP to the sea floor and hoisting the ADCP back to the structural skid/deck. The structural skid and deck for ADCP is made from carbon steel (coated) and atop the deck there is grating made from FRP.

Other places of installation for Acoustic Doppler Current Profiler are noted; that this equipment can be fitted in a horizontal position on a seawall or bridge pilings in rivers to measure the current profile from one pre-determined location to the other, and to the bottom of ocean-going vessels to take constant current measurements as the vessel moves. In very deep areas, they can be lowered on a cable from the surface (refer to narrative above speaking about Auger Winch and among others but not limited to, a 28” diameter Sheave 78 Series with 1/8” thick urethane lining).

As stated, Decundi inspectors carry out inspection during the manufacture, assembly and testing (F.A.T) of the equipment with satisfactory result and a comprehensive report of the findings is then sent to our client. Please contact us if you require these inspection services.

We also carry out inspection of P-Tanks on the Topside of Offshore Platforms (1st picture).
