Technology overview

How ZIMA works, at a high level.

ZIMA pairs underwater swerve-drive mobility with close-range UV-C treatment, operating on a prevention-first cadence: short, repeatable passes that stop early-stage growth before it becomes established fouling.

Build and test media

From fabrication and integration to the water.

Assembly sequence

Bench integration

Assembly, treatment hardware, and electrical integration on the rebuilt prototype.

Interactive demo

Fouling never stops. See what prevention looks like.

Growth keeps appearing on the plate below. Drive the rover yourself, or switch to auto passes to see how short, repeatable maintenance cycles keep a hull close to its clean baseline.

Operating logic

What the system is designed to do.

Adhering mobility platform

A hull-climbing platform designed to stay attached and move predictably across curved steel surfaces.

Close-range UV-C treatment

A compact treatment module designed to target early-stage growth before it becomes established fouling.

Frequent maintenance passes

Regular treatment cycles keep the hull closer to a clean baseline instead of letting buildup accumulate.

Container fleet relevance

ZIMA is being developed around commercial operating reality: repeatability, coverage, uptime, and easier integration into maintenance workflows.

Simulation demo

Early simulation of ZIMA’s motion and pathing. Real-world passes would use tighter, more closely spaced patterns.

Industry Issues ZIMA Addresses

A cleaner hull changes cost, compliance pressure, and environmental impact.

Three industry problems make prevention-first hull maintenance matter.

55,000
tonnes of microplastics released from ship and yacht coatings each year
Toxic Antifouling

Toxic Antifouling

Operators have long relied on coatings and reactive cleaning to manage fouling. A prevention-first system creates a path to reduce how much the hull depends on harsher intervention.

ZIMA is designed to support cleaner hull upkeep before the pressure for aggressive intervention builds.

of current global emissions linked to the fuel burden created by fouled hulls
Carbon Emissions

Carbon Emissions

Even thin fouling layers raise drag. Keeping the hull cleaner more consistently can lower the fuel penalty that builds between major cleaning events.

The system is built around preventing the drag penalty that operators end up paying for later.

80%
of invasive marine species transfer associated with biofouling hulls
Invasive Species

Invasive Species

Biofouling is a transport pathway. Preventing organisms from establishing on the hull can help reduce transfer risk between ports.

A prevention-first maintenance rhythm can help protect not just vessels, but the waters they move through.

Development story

Built through iteration.

Our early proof-of-concept hardware and hands-on underwater robotics work shaped the team’s approach to subsea design. Today, we’re developing ZIMA’s custom swerve drive, UV-C treatment hardware, electronics, and controls together, moving from CAD to machining and assembly. Working on the complete rover helps us see how the parts fit together and what to refine in the next build.
