The Logic: A ship is "Floating Hardware." Cleaning the bottom keeps it from slowing down, crashing, or breaking.
- LOTO (Pre-Op): Lock Out, Tag Out. This is Step Zero. Engines and thrusters must be physically locked and tagged "DO NOT START." If the hardware starts, the diver is gone.
- Diver Flag: The Alpha Flag (Blue & White) must be hoisted to tell other ships to stay away and slow down.
| Step | Item | Logic |
|---|---|---|
| 01 | CCTV (Pre) | The Scan: Cameras find the marine fouling before starting. |
| 02 | Brush Kart | The Clean: A vacuum spinning scrubber kart that sticks to the ship to remove barnacles and slime. |
| 03 | Scraper | The Detail: Hand tools for tight spots the kart can't reach. |
| 04 | Polisher | The Smooth: Buffs propeller blades like a mirror to save 20% fuel. |
| 05 | CCTV (Post) | The Audit: Final video scan to prove the hull is clean and smooth. |
- Gap Check: Using tiny metal rulers (Gauges) to make sure parts haven't worn down or shifted.
- Hot-Swap: Plugging a hole from the outside so a part can be replaced inside without the ship sinking.
- Water-Shield: Fitting a big waterproof box to the hull to create a dry space for underwater welding.
- Seal: Diver fits the Plug or Box over the work area.
- Drain: Pump out the water to create a safe, dry seal.
- Signal: Diver knocks 1-2-3 to tell the crew: "Safe to open!"
- Repair: Fix the hardware while the ship stays in the water.
- Smooth is Fast: A clean hull removes the "bugs" and "lag" from the ship's performance.
- Safety is Binary: There is no "Undo" button underwater. Either the LOTO is on and the flag is up, or the operation is a hard fail.
