Seawise DMS

Controlled documents, done properly.

Seawise DMS is an enterprise controlled-document platform for ISM/ISO documents: revision-controlled, approval-workflowed, per-user watermarked on view, and backed by an append-only SHA-256 audit chain you can hand to a class auditor.

Why it matters

One true version, fleet-wide — and you can prove who read it.

One true version, fleet-wide

No more 'is this the current revision?' across ship and office.

Controlled copies that stay controlled

Every on-screen view is stamped with the viewer's name, time and classification — re-stamped each view, never persisted.

Prove who read what

Per-user, per-revision read receipts — the answer to the #1 ISM finding.

Tamper-evident by design

An append-only hash-chained audit log with periodic verification you can show an auditor.
