![]() ![]() Records all in the survey book includes with the density for Ballast and Bilges, and for Oil complete it with density and temperature. The Fresh Water was at density 1.000.īut if not the reference pattern is for Fore Correction or Fc = (Fd x AT): LBM and After Correction or Ac = (Ad x AT) / LBM. Determining of deductible weights by measuring and sounding Deductible Weight could measure by sounding the tanks which used the Sounding Tape or gauging the tank level by visual inspection. Any deductible weight such as Ballast Water, Fresh Water, Fuel and Diesel Oil, and Bilges is notify to check. ![]() Records the water dock density as survey data. Inserted the Hygrometer on to the water sample on the Sampling Can or Tube, then we could check the scale pointed on the surface of the sampling water. To determine the density of water, we need the instrument named Hydrometer or Density Meter. The sea water density is indeed at density 1.025 and the fresh water at density 1.000. Where as the water density is subject to changes which follow with water tide that carrying different water salinity and temperature on to the ship dock. ![]()
