SmartMarine® 3DOffshore Coordinate Systems

To support the modeling of offshore structures, SmartMarine® 3D supports both ship and geographic style coordinate systemsCoordinate systems with grid planes can be created with Grid Wizard in Grids task environment

SmartMarine® 3DOffshore Coordinate Systems (continued)

Grids type is typically used for offshore grid planesBearing axis and origin location are reported using cardinal directions (North, South, East, & West)Multiple coordinate systems can be created in single databaseAny coordinate system may be used as reference coordinate system for placement

SmartMarine® 3DGrid Lines

Grids type coordinate systems display grid lines by default– Grid lines are associated with intersections of grid planes at each

elevation plane

Ship type coordinate systems do not display grid lines by default

SmartMarine® 3DAngled Grid Planes

Coordinate systems may also have angled grid planes– Useful for creating jacket structure

SmartMarine® 3DAngled Grid Planes (continued)

Edit grid plane properties– Set Axis of Rotation– Set Angle of Rotation

Needs to be done individually for each angled grid plane– Axis and angle settings often are different for each grid plane
