INTRODUCTORY NOTES

Applicability

This information is applicable to the following vessel for MDC Project 3065:

MDC Hull Number Vessel Name

855 TBD

The vessel is a floating crane, intended for rivers, inshore, intra-coastal and protected waters within the Norfolk District area of operations.

Notes

The hydrostatic calculations are based on the molded displacement.

The calculations do not account for the shell plating.

The calculations are for fresh water, specific gravity 1.000

The calculations assume no trim and no heel.

All weight units are long tons, equal to 2240 pounds.

All length units, unless noted, are in feet-inch.

The “f” and “a” suffixes to the table values indicate positions forward or aft of midships.

855-B125-01 Page 2 of 7

DEFINITIONS

BPL: Baseplane, the horizontal plane of the bottom of the vessel.

KML: Distance in feet from the BPL to the longitudinal metacenter.

KMT: Distance in feet from the BPL to the transverse metacenter.

LCF: Longitudinal Center of Flotation, in feet from midships.

LCB: Longitudinal Center of Buoyancy, in feet from midships.

Midships: The longitudinal center of the Vessel.

Moment / In Trim: The moment required to trim the vessel by one inch.

Trim: The difference between drafts at the forward and aft ends of the vessel.

VCB: Vertical Center of Buoyancy, in feet above the baseplane.

Weight / Inch: The amount of weight required to sink the vessel by one inch.

Cb Block Coefficient.

Cp Prismatic Coefficient.

Cf Waterplane Coefficient.

INTRODUCTORY NOTES

This information is applicable to the following vessel for MDC Project 3065:

MDC Hull Number Vessel Name

855 TBD

The vessel is a floating crane, intended for rivers, inshore, intracoastal and protected waters within the Norfolk District area of operations.

Notes

1) The permeability of all tanks is assumed to be 0.98.

2) The following definitions are used in the tank sounding tables:

a) Sounding (Ft – In) = depth of the liquid in the tank, in feet and inches, measured from the bottom of the tank.

b) Volume (Gallons) = volume of the liquid in the tank, in gallons, corresponding to the sounding.

c) Weight (LT) = weight of the liquid in the tank, in long tons of 2240 pounds, corresponding to the sounding and the specific gravity of the liquid in the tank.

d) LCG (Feet) = longitudinal center of gravity of the weight of the liquid, in feet, measured from the Amidship.

e) VCG (Feet) = vertical center of gravity of the weight of the liquid, in feet, measured from the Baseline.

f) TCG (Feet) = transverse center of gravity of the weight of the liquid, in feet, measured off the Centerline, port (p) or starboard (s).

g) FSMt (LT-Feet) = transverse free surface moment of the liquid in foot-long tons.

h) FSMl (LT-Feet) = longitudinal free surface moment of the liquid in foot-long tons.

INTRODUCTION

This information is applicable to the following vessel for MDC Project 3065:

MDC Hull Number Vessel Name

855 TBD

The vessel is a floating crane, intended for rivers, inshore, intracoastal and protected waters within the Norfolk District area of operations.

Purpose

To demonstrate compliance with specified damaged stability requirements at operational drafts and conditions, as specified in the vessel specifications.

Criteria

The contract specifications require the following:

USCG regulation 46 CFR Subchapter C, Section 28.580 Unintentional flooding, (f) Survival Conditions.

(1) The angle of equilibrium after flooding does not exceed 25° (0.44 radians);

and

(2) Through an angle of 20° (0.35 radians) beyond the angle of equilibrium after flooding, the following are met—

(i) The righting arm curve is positive;

(ii) The maximum righting arm is at least 4 inches (102 millimeters);

(iii) Each submerged opening is capable of being made weathertight; and

(iv) The heeling arm caused by deploying all fully loaded davit-launched survival craft on one side of a vessel does not exceed the righting arm at any angle of heel beyond the equilibrium angle when launching is assumed on the damaged side.

Additional Criteria: 3” margin line remain above the equilibrium waterline following damage.

CALCULATION NOTES

• The calculations are based on the molded dimensions.

• The calculations are for fresh water, specific gravity 1.000

• The initial heel is assumed zero.

• All weight units are long tons, equal to 2240 pounds, and all length units, unless noted, are in feet.

• The Damage Stability analysis were performed for the following conditions:

1. Counter-Ballasted condition – No Significant Deck Load.

2. Ballasted condition – No Significant Deck Load

• For this analysis, the survival criteria is evaluated for single compartment damage condition.

• Per 46 CFR 28.580(f), all submerged openings through an angle of 20° beyond equilibrium shall be capable of being made weathertight. For this vessel design, all hatches on the deck are watertight. In addition, all compartment/void vents are the gooseneck type with hinged covers or inverted ball checks and can be closed to be weathertight. This survival criteria is satisfied.

• Due to symmetry about centerline, damage stability calculations were only considered for the one side (starboard) of the barge.

• GHS computer software (Creative Systems Inc., Port Townsend, WA (360) 385-6212) was used extensively in the development of this document.

RESULTS

In all conditions, the barge satisfies the survival requirements identified in 46 CFR

28.580(f) with any single compartment damaged and flooded.

SURVIVAL CONDITIONS

(1) The angle of equilibrium after flooding does not exceed 25 deg.

(2) Through an angle of 20 deg. beyond the angle of equilibrium after flooding, the following are met,

- The righting arm curve is positive;

- The maximum righting arm is at least 4 inches;

- Each submerged opening is capable of being made weathertight
