Grounded Intelligence for Every Reefer Alarm

Topic: Star Cool Compressor Service & Stock
ETO on Watch AI Technical Advisor
100% Grounded OEM Mode
Try Live Scenario:
Ask @ai about alarms, OEM manual citations, or spare parts in store...

100% OEM Manual Grounded

Strictly cites official Carrier, Star Cool, Daikin, and Thermo King factory service manuals with exact page numbers.

Live Vessel Database & Spares

Directly queries your vessel's database for live container telemetry, active alarm status, and exact spare parts stock levels in the ship's inventory.

Ship-to-Shore Collaboration

Conversations and diagnostic steps sync between the vessel PC Hub and Fleet Office Dashboard, keeping superintendents and ETOs aligned.

Copyright-Safe Architecture

Operates strictly on factual engineering parameters, manual references, and on-board data — ensuring complete compliance without copyright infringement.

Absolute Reliability

Works offline at sea. No data loss during outages. Automatic recovery once reconnected.

Fleet Transparency

Monitor container health and maintenance history across the globe from a single login.

Operational Efficiency

Reduce manual paperwork by 80%. Speed up repairs with smart mobile diagnostics.

Infinite Scalability

Scale from a single vessel to hundreds of ships and thousands of reefers effortlessly.

Engineers

Ditch the paper. A mobile tool that makes daily rounds faster with high-contrast day & night modes for perfect visibility.

Managers

Real-time data for real-time decisions. No more waiting for end-of-voyage reports.

The Company

Lower risks, optimized spare part costs, and absolute protection of cargo quality.

Cyber Risk Management

Built with Maritime Cyber Risk in Mind

Designed around the principles of IMO Resolution MSC.428(98) and IACS cyber resilience guidance — architecture choices made from day one, not bolted on after.

Data at Rest

AES-256 Encrypted Database

All local vessel records, temperature logs, and spare parts inventory on the PC Hub are encrypted at rest using AES-256 (via SQLCipher) — the same encryption standard used across regulated industries.

Data in Transit

TLS 1.3 & Zero Inbound Ports

Cloud synchronization runs exclusively through authenticated HTTPS / TLS 1.3 encryption. The desktop application opens zero listening ports or background daemons on the vessel network, significantly reducing the vessel's exposed attack surface.

Air-Gapped Sync

Isolated Offline P2P Sync

Mobile-to-PC deck data exchange connects via direct USB cable tethering. Operates independently of open or unsegmented shipboard Wi-Fi networks to prevent wireless sniffing and interception.

Cyber Resilience

100% Offline Autonomy

Designed for full operational continuity during satellite (VSAT) dropouts, emergency network isolation, or cyber-incident lockdowns. Routine monitoring and compliance logging never stop.

Built to Support Your SMS Documentation

The architecture — encryption at rest, TLS in transit, air-gapped sync — is designed to align with the kind of controls Class societies (DNV, Lloyd's Register, Bureau Veritas, ABS) look for during cyber audits. We're happy to walk your compliance team through the technical implementation directly.

About Me

10 years in the engine room — before I ever wrote a line of code.

I'm a marine electrical engineer. ReeferControl wasn't born from a business plan — it came from being worn down by the exact same problem every fleet faces: the constant risk of lost cargo.

This is currently a one-person engineering project — not a startup with a sales team. That's exactly why every feature is tested against real deck operations, not a product roadmap meeting.

I'm not here to sell you software. I built this to solve a problem I live with at sea. If it holds up the way I believe it will, I'd rather see it running on real ships than sitting on my own laptop.

Here's how it protects your cargo and removes human error from the equation:

1

Catching temperature deviations instantly

Finding a deviation among 1,000 reefers usually means trusting tired crew members or manually digging through massive Excel dumps. ReeferControl automates this — whether your data source is automated modem reports or manual bay rounds. The app parses the 3x-a-day modem reports (where available) and instantly flags out-of-range containers. Even if a seaman logs a wrong temperature manually during a bay round, the system cross-references it with actual modem data where possible and highlights the discrepancy — cutting human error out of fault detection almost entirely.

2

"Ghost" spare parts lead to lost cargo

A missing spare part isn't just an inventory annoyance — it's a direct threat to the cargo. You think a critical part is in stock, but a previous crew used it, didn't log it in their disconnected Excel files, and never reordered it. When a reefer fails, you can't fix it in time. ReeferControl replaces this "Excel Hell" with a unified system. No complex PMS integration needed — just one clean app where inventory is accurate, so you always have the parts to keep reefers running.

3

Built for offline reality

Standard maritime software breaks when the VSAT goes down. ReeferControl is built for zero connectivity: the Android app and PC dashboard sync flawlessly offline via a simple USB cable — no dependency on a live satellite link. Data syncs to Firebase when a connection is available, replacing the practice of sending unencrypted Excel files through the Master's email. And if the internet is out entirely, the engineer can still export a standard Excel report in one click for the Master to send.

From a personal tool to a fleet-wide ecosystem

What started as my personal survival tool is now the ReeferControl ecosystem: an Android app for the deck, a Desktop app for the ETO, and a Fleet Dashboard for the office.

Every feature is checked against one question: would this have helped me at 3 a.m. standing in front of a faulty reefer?

How this works in practice

I've built and tested this against every real workflow I go through with actual reefer containers — a demo environment shaped entirely by day-to-day operations, not a lab exercise. I'm open to bringing it onto a working vessel to prove it out there, at no software cost — the only ask is covering the infrastructure it runs on (database hosting), which scales with the number of vessels using it. No license fees, no sales pitch. Just a tool built by someone who's stood where you're standing, offered to the fleet that needs it.

Let's talk about what's actually costing your fleet time and cargo — and whether this solves it.
