Maritime Law
What this domain tests
The legal domain checks your grasp of the framework a chief engineer works inside: SOLAS, MARPOL, LL, COLREG and STCW as conventions; flag State versus port State control; the ISM Code and the Safety Management System; class and statutory certification; the master's overriding authority; reporting obligations and the consequences of non-compliance. Croatian examiners often pose a scenario - an accident, a detention, an oil spill - and ask who is responsible and what must be recorded.
Core rules and concepts
- Hierarchy. Conventions create obligations on the flag State, which implements them nationally and issues certificates; the ship must hold valid statutory certificates (Safety Construction, Safety Equipment, Safety Radio, IOPP, ISSC, SMC, DOC for the company).
- Port State Control. Under the relevant regional MoU, a PSC officer may inspect and detain for deficiencies; the master must be informed and has a right of appeal against detention. Detentions are published, and clearance requires rectification and sometimes a re-inspection.
- ISM Code. Company must have a DOC and the ship an SMC; the SMS covers procedures, emergency preparedness, maintenance, reporting of non-conformities, internal audits, and the master's overriding authority to make decisions that safeguard life and the environment.
- MARPOL reporting and records. Oil Record Book Part I (machinery space) and Part II (cargo), Garbage Record Book, Ozone-depleting Substances Record Book, Ballast Water Record Book. Entries signed by the officer in charge and each page by the master.
- Casualty and incident reporting. Note of protest, accident report to the flag State, and P&I notification. Witness statements and evidence preservation come first.
- Contracts and liability. Know the difference between seaworthiness obligations and due diligence; the concept of the Himalaya clause and limitation of liability, in outline only.
Worked example
A PSC officer finds the oily water separator's 15 ppm alarm defective and detains the ship. Reasoning: this is a MARPOL Annex I deficiency and a detainable item because the alarm is a mandatory safety measure against illegal discharge. Actions: master informed and detention notice obtained, SMS non-conformity raised, repair by class-approved service with certificate, entry in the ORB for any internal transfer, appeal considered through the flag State, and P&I/company notified. The answer scores if it separates the legal steps from the technical repair.
Traps that cost marks
- Saying PSC "arrests" a ship - arrest is a court action; PSC detains.
- Confusing DOC (company) with SMC (ship).
- Forgetting the master's overriding authority under the ISM Code.
- Not knowing that ORB pages are signed by the master.
- Treating the ISM Code as a technical standard rather than a management system.
