As marine surveyor, you might need organisation to develop your knowledge and experience. Today I will post you one of them called International Institute of Marine Surveying (IIMS). This is an independent, non-political organisation promoting the professionalism, recognition and training of marine surveyors worldwide. The IIMS is held marine surveying training, short courses and distance learning. Right now, the representative office was spread at several countries. Here a brief description about IIMS.
The IIMS is a membership organisation and since 2004 has increased its membership worldwide to cover 98 countries. It is the largest organisation of its kind in the world, and seeks to represent its industry to government and non governmental organisations such as the International Marine Organisation (IMO), Coastguards, insurance companies and ship owners.
Air draught – means the vertical distance from the surface of the water to the highest point of the ship’s mast or aerial.
Bale space capacity – is that cubic capacity of a cargo space when the breadth is measured from the inside of the cargo battens (spar ceiling) and the measured depth is from the wood tank top ceiling to the underside of the deck beams. The length is measured from the inside of the fore and aft bulkhead stiffeners.
Broken stowage – is defined as that space between packages which remains unfilled. The percentage that has to be allowed varies with the type of cargo and with the shape of the ship’s hold. It is greatest when large cases are stowed in an end hold or at the turn of a bilge.
Cargo information – means appropriate information relevant to the cargo and its stowage and securing which should specify, in particular, the precautions necessary for the safe carriage of that cargo by sea.
After reviewing some comments on the posts, I decided to write this post. Flash back, this post is explains several basic calculation that usually use by marine cargo ship surveyor to complete their jobs. I think this will be usable for beginner.
Vessel Trim Calculation
Trim is different between aft draft and forward draft of the vessel.
Trim = Draft Aft (DA) – Draft Fore (DF)
Example : DF: 5.40 M, and DA: 7.25 M
Trim = 7.45 – 5.40
Trim = 2.05 M (Apparent Trim / AT)
A few weeks ago, I have got the full version of Draft Survey Software, thanks to Capt. Michael from MW Marine Services, LLC that has given me free.
Now, I have time to post the review of Draft Survey software, so the reader could give comment and feedback to software owner for next expansion. This review is based on the software I have tested. Just continue reading to check the below test.
The below screenshot show how the software works:

Hi marine cargo surveyor. :). It was about three months with no posting, as I have faced busy days.
Previously, we have discussed topics about Draft survey : Terms of Conduct, Draft Survey : Procedures and Calculation, Draft Survey : Specimen of Calculation, How To Conduct Bunker Survey, and Bunker Survey Calculation. Appreciated every feedbacks and comments around the posts.
In this posts, I will generally introduce about cargo hold cleanliness survey. The hold cleanliness survey is conducted to ensure the cargo hold condition before loading by inspected whether the hold is ready to load the nominated cargo or not.
