Version: 3.1 Effective Date: 2026-03-25 Owner: Nils Johansson
JDS is the in-house documentation and quality management system for all engineering work produced under The Office of Nils Johansson. It defines how documents are created, numbered, reviewed, revised, stored, and retired.
Every document — whether it’s a field service report, a 3D model drawing, a timesheet, or a technical manual — follows the same system. This ensures consistency, traceability, and professionalism across all work.

Technical documents carry an engineering domain code so you can identify the discipline at a glance:
JDS-[CATEGORY]-[DOMAIN]-[NUMBER]
Example: JDS-DWG-MEC-003 (3rd mechanical drawing)
Example: JDS-RPT-MAR-001 (1st marine report)
System documents (procedures, templates, quality) omit the domain:
JDS-[CATEGORY]-[NUMBER]
Example: JDS-PRO-003
With revision: JDS-DWG-MEC-003 Rev B
| Code | Domain | Typical Work |
|---|---|---|
| MEC | Mechanical | Pumps, valves, flanges, brackets |
| MAR | Marine | Ship systems, engine room equipment |
| AUT | Automation & Controls | PLC, HMI, sensors, wiring |
| ELE | Electrical | Power, motors, generators |
| PIP | Piping | Pipe systems, fittings, P&IDs |
| STR | Structural | Frames, mounts, enclosures |
| TST | Testing & Measurement | Test fixtures, calibration tools |
| FAB | Fabrication & Prototyping | 3D printed parts, CNC, workshop |
| THR | Thermal & HVAC | Heat exchangers, cooling, ventilation |
| SFW | Software | Scripts, tools, applications |
| GEN | General | Cross-discipline |
