Description
On the Ship page you can use the ship's physical dimensions to create a virtual reference point (the Shop Origin) in a dedicated coordinate system for the ME70 system. The Ship Origin is normally located in the following position:
|
• |
X position: Half the ship's length |
|
• |
Y position: Half the ship's width |
|
• |
Z position: On the waterline |
If you want to change the location of the Ship Origin, you can do this by providing offset values in the X, Y and/or Z directions. To do this you will need the ship drawings.
NoteWe recommend that you 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.
Details
X Offset
Select the offset value on the X axis (fore-and-aft direction) from the default Ship Origin. This is the origin that was defined by the vessel designer and/or the shipyard when the vessel was built. Adjust with a positive value for X if your new preferred origin is located ahead of the default Ship Origin.
Y Offset
Select the offset value on the Y axis (athwartship) from the default Ship Origin. This is the origin that was defined by the vessel designer and/or the shipyard when the vessel was built. Adjust with a positive value for Y if your new preferred origin is located on the starboard side of the default Ship Origin.
Z Offset
Select the offset value on the Z axis (vertical) from the default Ship Origin. This is the origin that was defined by the vessel designer and/or the shipyard when the vessel was built. Adjust with a positive value for Z if the new preferred origin is located under the default Ship Origin.
Ship Dimensions
Insert the physical dimensions of your vessel (length and width).
Do this as accurately as possible. This information is used to create a new origin in the vessel coordinate system.
