Maritime Law, Statutory Regulations and Survey and Certification
Core concepts
Know the international framework: UNCLOS, IMO conventions, flag State responsibilities and port State control. Understand SOLAS chapters, MARPOL annexes, Load Line Convention, COLREGs, STCW and MLC. Certification content includes the major certificates and their validity: Safety Construction, Safety Equipment, Safety Radio, International Oil Pollution Prevention, International Sewage Pollution Prevention, Load Line, Safety Management Certificate and Document of Compliance, and the class and statutory survey regime (annual, intermediate, special, docking). Understand the role of the recognised organisation, the ISM Code's safety management system, the ISPS Code, and the survey cycle harmonisation system. Know how a certificate can be invalidated and the meaning of a condition of class.
Traps
Questions frequently test validity periods: the Safety Management Certificate is generally five years with an intermediate verification, while a Document of Compliance is also five years with annual verification. Do not confuse a condition of class with a recommendation. Another trap is assuming port State control can detain for a class matter alone; detention is for statutory deficiencies. Be careful with the difference between a statutory survey and a classification survey.
Worked rule of thumb
Use the five-year cycle as the anchor: special survey at five years, annual surveys each year, intermediate survey at the second or third anniversary. If a certificate expires during a voyage, extension is limited and only with flag State approval, and the survey must follow promptly.
