The news and information for marine surveyor, ship surveyors, cargo surveyors, marine cargo inspector, and the steps to conduct survey for draft survey, petroleum survey, bunker survey, includes marine survey software
A bunker quantity survey is taking measurements on board the delivery barge or at the shore tank and on the receiving vessel before and after transferring of oil takes place by involves an approved marine surveyors.
– Surveyor measurements the bunker tanks to determine the quantity of oil delivered.

Even though the procedure has been tightened, we may see some bunker tanker are still trying to play their tricks, therefore it is very important for Chief Engineer, Vessel’s Crew and Surveyor to know well their tricks.
Below are the Tricks of Bunker Supply, trust that most of our Chief Engineers might known the trick very well, or even know more other tricks. Hopefully by knowing these tricks we can do some prevention, counteract or countermeasure to protect our interest:
1. Manipulating the sounding result
It is very easy for the bunker barge operator to manipulate the sounding result.
Counteract/Countermeasure: Chief Engineer or bunker surveyor appointed should sound the bunker barge tanks himself

In this post, I would like to write about how to do tank sounding for ballast water and fuel oil.
Sounding Tools:
– Sounding Tape, in meter or feet. For Manual measurement of sounding, a measuring tape normally made up of brass and steel with a weighted bob attached at the end of the tape is used.
– Water Finder and Oil Finder Pastes. Sounding pastes are also available for both water and gas oil which highlights the level of fluid in tape.
Sounding Tanks Step of Works:
– Check the sounding tape and partly lowered on to the sounding pipe.
– Layered the suspected sounding depth with Water Finder Paste (if you check the ballast)
– Layered the suspected sounding depth with Oil Finder Paste (if you check the oil)
– Continued to lowered the tape until the sounding tape bob touching the bottom tank (datum plate).
– Roll up the sounding tape.
– Check the height of water / oil level that signed on the tape or  the finder paste  changes the color  to become red.
– Recorded the sounding.
– Check the trim and list of the ship for volume calculation.

Recently, I have updated marine survey software for better performance and assist your fast calculation during surveying. In this version there are some updates includes:
– Clean and Larger interface with simple and easy data input for the survey.
– The software created basis Microsoft Excel files that works best with excel 2007-2013 and it could also working with excel 97-2003.
– The presentation is creates by Microsoft Power Point basis, it totally free to download. All version PP enable to open this.
– Smaller size file and performs faster file access.
I have added some software relate to oil calculation. The software are:
1. BunkerCal
A Bunker Tank Sounding calculation program. Bunker survey calculation for tank sounding report based on ASTMÂ Table 54B .
Follow this link to know more http://www.sevensurveyor.com/software/surveysoft-marine-surveyor-software/
2. OilCal
A Petroleum calculation program. For shipboard survey with calculation and ullage report based on ASTMÂ Table 6A, 6B, 54A and Table 54B.

Hope the software is useful. Please try it and drop your comment here.

Just go to this link for downloading: http://sevensurveyor.com/software/. The list of software will be growing, I will load additional software when available.
Just leaving your comment about Software for Marine Cargo Surveyor.

PS: If you need the complete calculation software you could search on the web, it is available to buy online. For the ASTM Table complete version, you could check at this link http://www.astm.org/BOOKSTORE/ADJUNCT/ADJD125010.htm
The bunker calculation is simple and needs the following:
– Tank Sounding data and Tank Capacity Table. The Corrected Sounding means below is the sounding after correcting with vessel’s trim and list.
– Temperature of Oil on Tanks,
– Oil Density @15*C,
– Table ASTM 54B (VCF) and Table ASTM 56 (WCF).
Now we could go with sample of 1 tank to test the calculation.
