Verifying vessel origin and ship dimensions
The physical length and width of the ship are important parameters that need to be
recorded in the SU90 software.
Prerequisites
For accurate location of the ship dimensions, you need the detailed vessel drawings.
Neither tools nor instruments are required. The SU90 system is turned on and operates
normally.
Context
It is common practice to place the
Ship Origin
at the same position as the motion
reference unit (MRU). This will minimize the vectors when your vessel is moving. Use
the vessel drawings to establish the offset values between the basic position of the
Ship
Origin
and the MRU location.
If you do not have a motion sensor you can place the
Ship Origin
at any location on the
vessel. We suggest that you place the origin under the captain’s seat on the bridge. All
sensors will then be referenced to this position. Whenever a sonar is used with short
ranges, this will provide a more precise presentation.
