Impressed current cathodic protection of deep water structures
(1994)Of all the various anti-corrosion systems usEd. by offshore structures and ship-building industry to reduce the ravages of sea-water corrosion, cathodic protection is one of the most important. Impressed current cathodic ... -
Optimal estimation of ship's attitudes for beampattern corrections in a coaxial circular array
(Taylor and Francis, 1994)A study is conducted to estimate the accurate attitude of a ship's motion and the estimation is used to arrive at the corrections required for a farfield pattern of a coaxial circular array. The relevant analytical expression ... -
A temperature profiler
(Publ. and Inf. Dir., New Delhi, India, 1994)An instrument developed for measuring temperature profiles at sea in depth or time scales is described. PC-based programming offers flexibility in setting up the instrument for the mode of operation prior to each cast. A ... -
Determination of wave direction using an orbital following buoy
(Publ. and Inf. Dir., New Delhi, India, 1994)Software has been developed in FORTRAN language using a personal computer for the determination of wave direction from time series measurements of heave, pitch and roll of an orbital following buoy. The method of digital ... -
Use of sparker signal to classify seafloor sediment
(Publ. and Inf. Dir., New Delhi, India, 1994)During the cruise 190 of R.V. Gaveshani, the sparker signal was recorded in the analog form on audio cassettes. This signal has been digitized and a statistical computation, viz. the normalized cross-correlation function ... -
Spectral irradiance measurements using a novel spectroradiometer
(Publ. and Inf. Dir., New Delhi, India, 1994)A novel design of a spectroradiometer has been implemented and tested in the sea to measure underwater optical and physical properties. The spectroradiometer has two high resolution diffraction-based spectrographs assembled ... -
