Purpose

To specify an offset of an attached vessel from its initial position.

Theory

Refer to Vessel Offsets for further information on this feature.

Keyword Format

A block of two lines defining the offset, repeated as many times as necessary:

VESSEL=Vessel Name

OFFSET=X Offset [, Y Offset] [, Z Offset] [, Yaw Offset] [, Roll Offset] [, Pitch Offset]

Data for any Vessel Name specified here must be input under *VESSEL.

Table Input

Input:

Description

Vessel:

The name of the attached vessel.

X:

The magnitude of the vessel offset in the global X-direction.

Y:

The magnitude of the vessel offset in the global Y-direction. This entry is optional and defaults to zero if omitted.

Z:

The magnitude of the vessel offset in the global Z-direction. This entry is optional and defaults to zero if omitted.

Yaw

The vessel rotational offset about the vertical or global X direction. This entry is optional and defaults to zero if omitted.

Roll

The rotational offset, in degrees, about a vessel local surge axis. This entry is optional and defaults to zero if omitted.

Pitch

The rotational offset, in degrees, about a vessel local sway axis. This entry is optional and defaults to zero if omitted.
