What is a ullage report?
A form used to record the ullage readings in a vessel’s tanks which is then used to determine the amount of cargo within the tanks on a vessel.
What is tank sounding arrangement?
To maintain ship’s stability, equilibrium, and hence the safety it is necessary that the level of the fluids is checked at regular intervals of time. The process of checking level of fluid in various tanks of ship is known as “sounding” of the tanks.
What does an Innage sounding measure?
The Innage method will tell you the actual depth of the liquid in the tank. An oil gauging tape measure with a plumb bob is lowered down from the reference point just to the point that the bob touches the bottom of the tank or datum plate. Innage oil gauging tapes are used with Innage plumb bobs.
What does 90% ullage mean?
Ninety percent ullage is the ullage minus 10% of the tank capacity. The 90% ullage volume is the amount of fuel that should fit in the tank without triggering the overfill prevention device. The 90% ullage number can be used to determine the amount of fuel to order.
How do you use ullage sounding?
When measuring level by ullage method, the sounding tape is inserted only till the bob/ tape touches some part of the fluid top surface. Instead of measuring the whole depth of the tank, only the free space (from the top of sounding pipe to liquid surface) is measured (Check Figure).
How do you take a sounding of tanks by Innage?
An innage is typically only taken when you know the tank is near empty. To take an innage, (a measure of the liquid in the tank, from the bottom of the tank to the top of the liquid), use the pointed weight, and attach it to the tape measure and lower that thing down your tube.
What does it mean to take a sounding?
take soundings in British English to try to find out people’s opinions on a subject. She will take soundings of the people’s wishes before deciding on a course of action.
How deep is a Fanthom?
6 feet
Fathom, old English measure of length, now standardized at 6 feet (1.83 metre), which has long been used as a nautical unit of depth.
What is the difference between ullage and sounding?
Sounding is the measured height of the fluid from the surface of the fluid to the bottom of the tank. Ullage is the void space in the tank measured from the top of the tank to the upper surface of the fluid.
How is ullage measured in a gas tank?
Sounding is the measured height of the fluid from the surface of the fluid to the bottom of the tank. Ullage is the void space in the tank measured from the top of the tank to the upper surface of the fluid. Ullage is measured when the content of a tank is highly viscous and if the tank is filled to the maximum.
What is the volume of an ullage bunker?
THE VOLUME OF ULLAGE IS 105.529.m3 ,THIS IS OBSERVED VOLUME, TAKE THE TEMPERATURE OF THE TANK THE TEMPERATURE IS 48°C. AS THE BUNKER DELIVERY NOTE THE DENSITY OF THE BUNKER IS 988.KG/m3.AT 15°C.
How does the ullage tape and Bob procedure work?
Ullage Tape and Bob Procedure is an established way of measuring petroleum in tanks. This procedure is carried out by measuring the leftover space between the reference point on the ullage hatch and the top level of the liquid inside the storage tank. (PDF) ullage dipping of bulk fuel storage Tanks
