Executive Summary:

Damage stability calculations were performed to satisfy US Army Corps of Engineers scope of work for the Driftmaster replacement vessel, USACE MDC Project 2801.

The subject vessel is a Subchapter I Cargo and Miscellaneous Vessel subject to Subchapter S stability requirements, which has no applicable statutory damage stability requirements. As a catamaran, the vessel is capable of developing substantial righting energy and maintaining positive stability characteristics so long as damage is limited in extent. She is substantially subdivided transversely to minimize flooded length in the event of grounding or collision. She is also subdivided longitudinally into port demi-hull, cross-deck, and starboard demi-hull. Additionally, the normally-emerged cross-deck provides substantial reserve buoyancy once immersed and also prevents progressive cross-flooding which may exist on a monohull, due to its watertight boundaries as well as its elevation high above baseline.

The vessel was therefore evaluated simply to assess the resulting attitude (heel and trim) and potential for further downflooding, as well as an analysis to inspect that positive GM exists, and to inspect the righting arm curve to ensure positive righting arm exists in each case of damage.

Estimated lightship properties are as follows:

Lightship Particulars:

Displacement 528.90 LT

LCG 65.97 ft aft of frame 0 VCG 13.41 ft above baseline

Based on the results of these calculations, the subject vessel complies with the self-imposed damage stability criteria when the various damage scenarios are applied to the vessel while in all phases of anticipated operating conditions, including the deepest draft condition. Substantial residual righting energy and range of heel remain before submerging downflooding points leading to progressive flooding.

Vessel Description, Load Conditions, & Damage Scenarios:

Vessel Description:

Owner: United States Army Corps of Engineers Name: TBD (presently Driftmaster Replacement) Official Number: TBD

Length: 148’-0” Beam: 39’-0” molded Depth: 15-6” molded

The critical down flooding points for righting energy requirements are the aft and side generator room doors port and starboard (located 115’-6” and 99’-2” aft of frame 0, respectively, 17’-6” above baseline, and 12’-3” and 15’-6” off centerline, respectively). The doors are gasketed and capable of being dogged closed watertight. The propulsion motor room exhaust inlets port and starboard located high at the aft end of the sides of the main deckhouse (115’-5” aft frame 0, 22’-3” above baseline, and 15’-6” off centerline) are the critical downflood points that cannot be secured watertight.

Engine room intakes port and starboard on the 01 deck, propulsion motor room intakes and auxiliary machinery outlets are also monitored for downflooding, but do not present the most critical non-watertight openings due to their elevation and/or longitudinal location. All other air pipes are equipped with inverted vent check valves providing watertight seal in the event of submergence. All are modelled symmetrically to reflect damage to port or starboard side.

Load Conditions:

Damage stability was evaluated to encompass all anticipated intact loading conditions including lightship, departure, departure with recovered debris on deck, and arrival with recovered debris on deck. Tankage is divided into relatively small cubic tanks independent of the shell, so lightship closely correlates to a burnt-out condition. The initial intact conditions are summarized below, corresponding to those employed in the intact analysis of document 740-B155-01:

*Includes free surface moment

Maximum free surface moment was calculated by GHS and used in all applicable calculations.

Damage Scenarios:

Damage stability evaluation inspects asymmetric flooding of each starboard-side demihull compartment individually (vessel has a slight starboard heel at equilibrium and is symmetric about centerline, so port cases are omitted as redundant), representing a single compartment standard as applied to this multihull vessel.

To assess stability performance due to symmetric damage to both demi-hulls simultaneously (representing a low-energy grounding or collision) a symmetric case of damage to both the port and starboard forepeaks is included.

Finally, to represent a high-energy grounding or collision, damage to both the forepeak and the adjacent void compartment is included, with simultaneous damage occurring on the port and starboard demihulls, for a total of four damaged compartments.

Cross-deck damage was not evaluated, as it is not normally an immersed buoyant volume, so local penetration of the forward-most cross deck or the main cross-deck in way of the deckhouse will not affect trim, heel, or stability unless water is introduced into the space via heavy seas or the like. Damage to these spaces would most likely occur either due to impact with a dock or with another vessel in a congested harbor, where seaway effects would be negligible.

Stability Criteria:

Damage stability criteria do not exist by regulation for this vessel. However, to assess the residual range of heel to downflooding and the susceptibility to subsequent heeling and flooding when in the damaged condition, two criteria were applied in the evaluation.

The angle from the damaged equilibrium position to the point of progressive downflooding is assessed, as is the GM remaining after damage. Righting arm curves were inspected to ensure significant residual righting arm occurring at angles well beyond equilibrium.

Results:

Damage Criteria

The analysis indicates the vessel complies with the self-imposed criteria when subjected to the damage scenarios in all anticipated intact loading conditions, including the deepest intact loading condition.

Resulting draft, trim, heel, range of heel to subsequent downflooding, and available GM is summarized below for damage to the indicated compartment(s) while in the indicated initial condition:

In each instance, the most destabilizing asymmetric damage condition is due to flooding of the propulsion motor room.

Loss of waterplane from this compartment leads to increased draft and reduced residual righting arm, producing the minimum residual range to the point of downflooding. The minimum residual range is demonstrated in the heaviest ‘departure, with deck cargo’ condition, and provides 22.5 degrees beyond equilibrium. Residual stability is drastically better than a typical monohull.

The most destabilizing symmetric damage condition is the high-energy collision scenario, where both forepeaks and both compartments aft of the forepeaks are damaged. Despite the damage, the vessel still produces positive righting arms in excess of 5 feet to near 36 degrees beyond equilibrium, again when the damage occurs in the deepest draft condition.

See Appendix A through D for the detailed GHS output representing the synopsis above.

Description of Numeric Model Used in Analyses:

Creative Systems’ General Hydrostatics (GHS 16.00) hydrostatics & stability software package was used in all analyses.

The model of the subject vessel was created from an import of surfaces from Rhino3D, from which the lines plan and offset table was created, augmented with tanks, seachests, and sail components to reflect the overall vessel configuration.

Conclusion:

Under the assumed loading conditions, the subject vessel is in compliance with the assumed damaged stability criteria.
