DIVCAAS
DIVING COMPETENCY ASSESSMENT & ASSURANCE SCHEME
A fully digital, IMCA C 003 compliant progressive web application replacing all paper-based competency records, assessments, certificates, and approvals — accessible on any device, online or offline.
Type of Application
A Progressive Web App (PWA) — opens in any browser, installs to the home screen like a native app, works fully offline, and syncs data in real-time when connected.
Browser-Based — No App Store Needed
Runs in Chrome, Safari, Edge, Firefox. No download from an app store. Just open the URL and tap "Add to Home Screen".
RESTful Cloud Database
All portfolios, assessments, evidence, certificates, and approvals stored securely in the cloud with automatic backup.
Role-Based Access Control
Four portals — Candidate, Assessor/Verifier, Observer, and Admin — each with permissions matching the IMCA hierarchy.
Offline-First with Service Worker
Full functionality even without internet. Data syncs automatically when connectivity returns. Cache strategy: Network First, Cache Fallback.
In-App Toast Notifications
Instant in-app alerts on every key action — registration, signoff, certificate approval, rejection — displayed live across all portals without any external service.
QR Code Verification
Every issued certificate embeds a QR code. Scan on-site to instantly verify the diver's competency and certificate validity.
Why Paper-Based Systems Fail
Traditional competency portfolios create delays, risk, and compliance gaps
| Challenge | ❌ Paper / Manual Process | ✅ DIVCAAS Digital |
|---|---|---|
| Portfolio access offshore | Physical folder — can be lost or damaged | Available on any device, anytime |
| Assessment signoff | Paper form, wet signature, then scanning/emailing | Digital signoff with e-signature, instant notification |
| Certificate issuance | Days of admin to produce and post certificate | Issued digitally in minutes, QR-verifiable |
| Evidence documents | Photocopies filed in binders, easy to lose | Uploaded, tagged to units, stored in cloud |
| Compliance audit | Manual search through folders, days of prep | Admin dashboard with live filtering and export |
| Expiry tracking | Spreadsheet, easily outdated | Automated 5-year expiry dates, visible to all |

4. Complete Competency Units
Each unit has multiple elements. Candidates record evidence, upload documents, and mark competencies as demonstrated.

Security, Data, & Compliance
Built with security-first principles. All sensitive data is hashed and access is role-gated.
SHA-256 Password Hashing
Passwords are never stored in plain text. Hashed client-side using the Web Crypto API (SHA-256) before any transmission or storage.
Invite-Only Registration
No open sign-up. Cryptographic token embedded in invite links. Tokens expire. Cannot register without a valid invite from admin.
Cloud-Hosted Database
RESTful API backend with project isolation. All records are scoped to the DIVCAAS project. HTTPS only.
IMCA C 003 Compliance
Unit structures, entry criteria, and certificate format follow IMCA C 003 guidance. CCC UE Diving Ops Manual CM 011 §2 references embedded on certificate.
Full Audit Trail
Every action is timestamped: unit signoffs, approvals, rejections, certificate issuance. Admin activity log shows all changes with actor and time.
Certificate Verification
QR code on every certificate encodes cert number, name, ID, role, issue date, expiry, and verification URL. Scannable on any device.
