The vessel record is meant to be a quick reference for general information that is required for
multibeam surveying. Some of the information does not change from survey to survey and should
go either in the front of the book or the back of the book. A section of pages can then be devoted to
the information that does change from survey to survey or day to day.
As an example:
•
Page 1
– Plan of the vessel with all vessel measurements
•
Page 2/5
– Plan of the vessel with all offsets
•
Page 6/9
– Equipment list and interfacing information
•
Pages 10/20 – Dates of individual surveys with a listing of surveyors responsible for those
surveys
•
Pages 21/40 – Diary of draft measurements
•
Pages 41/60 –Diary of sound velocity measurements
As can be seen, this is a general reference which can provide dates and general details.
When naming surveys and sound velocities, a certain degree of logic in their naming will greatly
assist deciphering an individual event out of many events. In the case of sound velocity profiles, it is
common to name the profiles for the date that they were taken. A sound velocity profile taken on
04 July 2015 would be referred to as 20150704. If more than one profile is taken during the day,
then a letter suffix can be added: 201590704a, to separate the profiles, or time of cast can be added
to the file name. Keep in mind that personnel, who were not on board during the data collection,
may need to reference the information; keeping it logical and chronological will help.
Ensure that many blank pages are kept for the various categories. When a book is filled, plainly
mark on the cover the inclusive dates that the vessel log covers. If possible, also mark this
information along the spine of the vessel log. These logs should be kept in a safe and dry place on
the vessel.

Daily Survey Log
The Daily Survey Log is where all the details of the survey are recorded: start/stop time of the lines,
line names, and line direction, the speed of survey, and comments about that survey line. A copy of
the appropriate survey log should accompany all multibeam data along its path during processing.
Daily Survey Logs are of two types: rough and smooth. The smooth log is a sheet that is arranged in
rows and columns, where the appropriate survey information is entered, much like a spreadsheet.
It can be a single sheet that is printed out on board, or it can be professionally produced pad of
sheets. The rough log is similar to the vessel log; it is normally a ledger book; the start/stop times,
line name, line direction and comments are entered line by line, usually on the right-hand page as
they occur. The left-hand page then is left for details of the draft, sound velocity profile data, tides
or any other information that is pertinent to the lines that are detailed on the right-hand page.
