[Internal combustion engines and gensets](https://www.materialinsights.org/energy/e_engines/) (energy) and [Ship propulsion](https://www.materialinsights.org/energy/e_marine/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · 11% of flow · Internal combustion engines and gensets → Ship propulsion*

Large diesel engines drive most cargo ships.

- **11%** of Internal combustion engines and gensets's energy goes this way

### 2. Price link: propulsion

*Cost and price · Strong · Both ways*

Most ships are driven by large diesel or dual-fuel engines, a big share of construction cost. Monthly moves correlate at 0.19 and yearly at 0.68 with the engine index, a shared US manufacturing cost trend.

- **0.19** monthly change correlation
- **0.68** 12-month change correlation
- **1.15** fitted elasticity
