## Project summary

This project brought together two critical services in a single mobilisation: recoating of four box coolers and cleaning of two freshwater tanks. The combination reduced the client’s overall cost and downtime, and ensured consistent quality throughout.

## How we worked

The box coolers were manually scraped, high-pressure washed and sandblasted before being recoated with two layers of Säkatonit Extra AR-F. Cooler lids were cleaned, sandblasted and coated internally with Tankguard Storage.

In parallel, the freshwater tanks were drained, cleaned with Odin Gel (HOCNF approved), and flushed with high-pressure water. Rust spots were addressed and coated with Tankguard DW epoxy.

## Results

Both cooling and freshwater systems were cleaned, recoated, and documented in the same timeframe — cutting back on logistics, coordination, and service overlap. All work was completed to spec, and the systems were handed back ready for use.

## What we used

- Säkatonit Extra AR-F (coolers)
- Odin Gel (certified tank cleaning)
- Tankguard Storage & DW
- Scorex 06 sand for blasting
- HP water systems and custom coating station

## Reflections

Bundling these two services into a single scope gave the customer real value — both technically and economically. It’s a model we aim to repeat wherever possible, especially for coastal ferries and wellboats where downtime is critical.
