# Industrial Specification: Dynamic Positioning System

## 1. Technical Definition
A computer-controlled system that automatically maintains a floating crane's position and heading using thrusters and propellers.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1.0 m position deviation, 0.5-2.0° heading deviation**. Failure boundary: **Position deviation &gt; 5.0 m or heading deviation &gt; 10.0° for &gt; 30 seconds**, Mechanism: **Thruster saturation due to hydrodynamic drag exceeding maximum thrust capacity (F_max &lt; ρ·C_d·A·v²/2)**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.

| Symbol | Variable Definition | Localized Reference |
