Frequently Asked Questions

How much does PenLog cost?

PenLog offers flexible pricing based on your needs. We work with individual pen supervisors, contractors, and fleet operators. Contact us to discuss the best option for your operation. Early access users receive preferred pricing.

Do contractors need to create accounts?

No! Contractors get a simple link. They click it, submit pen status, upload photos, and they're done. No app downloads, no passwords, no training required.

Is our data secure?

Yes. All data is encrypted in transit and at rest. Photos are stored securely. We're GDPR compliant. Your dry dock data is yours—you can export it anytime in standard formats (PDF, Excel).

Does this work offline?

Currently, PenLog requires internet connection. Offline mode is on our roadmap for late 2026. Most shipyards have WiFi, but we understand connectivity can be spotty in some areas.

Is PenLog accepted by Flag State inspectors?

PenLog is designed to meet SOLAS Chapter II-2 documentation requirements for bulkhead penetrations. Our export format includes all information typically required during Flag State inspections. We're currently pursuing official approval from Bermuda, Panama, Marshall Islands, and Liberia Flag administrations. We recommend discussing PenLog with your Flag State surveyor before the dry dock.
