Hydrostatics Tests

BEND:

This is a test of the bending moment diagram of the Hercules vessel with a detailed weight distribution. It also provides a set of status reports in an intact case and in a flooded case.

CK_STOP:

This is a test of the option -STOP on the RARM command.

CLR:

This is a test of the different ways of computing the heeling arm by changing the location of the point of application.

DMARK:

This is a test of the ability to set the condition by specifying several draft marks and their readings.

FILL_APPROX:

This test shows how the -approximate option usess the correct CG and keeps the derivates (free surface moment) when it is filled.

HSTCMPX:

This is a hydrostatic example of a complicated body composed of several hulls with different orientations.

HSTTUB:

This test checks the hydrostatics of a single tube.

HULDAM:

This test produces righting arms at various yaw angles for a vessel with four vertical columns, one of which is partially damaged. It also shows how to use the wind and righting arm coefficient options.

HVRSTB:

This test checks righting arms at various yaw angles for a vertically oriented hull shape.

LS_FLOOD:

This test is a simple box which is used to compute longitudinal strength with a compartment flooded.

OSCSED:

This test checks the stability of a barge.

P_M:

This test checks longitudinal strength after moving a part. These files are further discussed as part of the workbook A Gentle Introduction to MOSES.

P_MPART:

This test is similar to p_m. Two shear and bending moment diagrams are created. Here the part begins near amidships. The first diagram is similar to that in test p_m. The part is then moved and equilibrium found then the second diagram is created.

S_OK:

This test all the options that make a check with the stab_ok command. The options are used both for intact and damage stability.

STABCOEF:

This test all the wind and rigting arm coefficient options available on the stab_ok command.

TANK_CAP:

This test computes a tank capacity table.

TIDE:

This tests the ability to change the tide.

TUBDAM:

This test is the same as HULDAM, except the model is comprised of tubulars rather than a hull definition.

WBEND:

This test is a simple box which is used to compute longitudinal strength in waves.

ADD_WEIGHT:

This test and the following one (LOST_BUOY) is a barge with two compartments symmertical about amidships. Here, the compartments are flooded while in the other one, the compartments are modeled as negative buoyancy.

LOST_BUOY:

This test and the previous one (ADD_WEIGHT) is a barge with two compartments symmertical about amidships. Here, the compartments are compartments are modeled as negative buoyancy, while the other one, they are flooded.
