# Industrial Specification: Ballast System

## 1. Technical Definition
A system that controls the stability and draft of a floating crane by adjusting water distribution in dedicated tanks.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-3.0 bar differential pressure across ballast pumps**. Failure boundary: **Structural failure occurs at 4.2 bar differential pressure or 85% tank volume capacity**, Mechanism: **Hydrostatic pressure exceeding ASTM A36 steel yield strength (250 MPa) or sloshing-induced dynamic loads exceeding tank baffle design limits**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Corrosion-induced wall thinning below 6mm thickness in seawater ballast tanks | 8 | Tank rupture at 2.8 bar operating pressure | Cathodic protection system maintaining -850mV to -1100mV potential relative to Ag/AgCl reference electrode |
| Ballast pump cavitation at NPSH below 2.1m at 1500 RPM | 8 | Impeller erosion reducing pump efficiency below 65% | NPSH margin of 1.5 times vapor pressure at 20°C seawater (2.34 kPa) |
