What Are the Disciplinary Sanctions for Forging Marine Radar Plotting Relative Motion Triangles?

Forging marine radar plotting sheet relative motion triangles, fabricating target vessel Closest Point of Approach (CPA) and Time to CPA (TCPA) calculations, or falsifying navigation bridge simulator instructor verification signatures carries severe academic sanctions, including automatic course failure (grade F), suspension for up to two academic semesters, or permanent expulsion from maritime training institutions. In nautical science curricula accredited by the International Maritime Organization (IMO) and the Standards of Training, Certification and Watchkeeping (STCW), radar navigation and manual plotting—including transferring relative radar vectors onto standardized plotting sheets to determine a target vessel’s true course, true speed, and aspect—represent a statutory collision avoidance competency governed by the International Regulations for Preventing Collisions at Sea (COLREGs); fabricating radar plotting records subverts maritime safety, risks catastrophic open-sea collisions, and constitutes gross professional navigational malpractice.

Nautical science examination boards and bridge simulator instructors enforce strict trajectory audits to detect fabricated radar plotting submissions.

1. The radar navigation course lecturer audits submitted plotting sheets and detects mathematically impossible target vectors that violate vector triangle geometry ($O-A-W$ triangle).
2. The chief navigation simulator technologist checks the full-mission bridge simulator session logs and confirms that the cadet never activated radar tracking scenarios during the scheduled testing session.
3. The technologist checks the simulator digital video recorder (DVR) and confirms that no manual radar vector plots were executed under the cadet’s assigned console identifier.
4. The cadet is formally issued a disciplinary query requiring them to perform a live manual radar plot on a dynamic multi-target scenario within a strict six-minute collision avoidance window.
5. Inability to demonstrate manual vector derivation leads to a formal charge of navigational data falsification and simulator record forgery.
6. The Head of Department forwards an investigative report to the School of Nautical Studies Board and the Institutional Cadet Disciplinary Committee.
7. The cadet appears before the disciplinary committee to defend their submissions under constitutional principles of fair hearing.
8. The Academic Board considers the committee’s findings and ratifies an order of rustication or summary expulsion, notifying NIMASA to bar watchkeeping certification.

Acquiring hands-on competency in radar plotting is essential for navigating officers who will take navigational watch and maintain lookout on commercial vessels worldwide.

• Standardized nautical radar plotting sheet manual with approved collision avoidance exercises.
• Raw bench workbook recording target ranges, bearings, plotting timestamps, and calculated CPAs.
• Navigation simulator bridge sign-in register confirming console allocation and scenario completion.
• Plotted relative motion vector triangles displaying determined target true course and aspect.

Cadets must record actual experimental measurements honestly, accounting for radar clutter and aspect changes, rather than manufacturing idealized collision avoidance data.

Under IMO STCW regulations and national maritime training standards, fabricating radar navigation logs is classified as severe maritime fraud, carrying mandatory expulsion and total debarment from officer-of-the-watch certification nationwide.

Maintaining rigorous laboratory ethics ensures that nautical science graduates develop sound technical judgement required to navigate commercial vessels safely across global waterways.
