MLC 2022 Amendments Shift From Paper to Detention Risk as Port State Control Tightens

The grace period is over. The 2022 package of amendments to the Maritime Labour Convention, 2006 crossed into binding force on 23 December 2024, and by early 2026 the transition from soft guidance to hard port state control enforcement is visibly under way. Inspectors are no longer flagging the new clauses as advisory; they are citing them in deficiency reports and, in a small but telling number of cases, stacking them into detainable outcomes.

Three clusters of amendments are driving most of the exposure. First, gender-appropriate personal protective equipment: shipowners must now provide ergonomically suitable PPE for female seafarers, including helmets, coveralls, gloves and safety footwear sized to individual physical characteristics, as summarised by the analysis from Chambers and Partners. Generic men's kit reissued to mixed crews is no longer a defensible practice. Second, dignified and timely repatriation — including of deceased seafarers — and guaranteed prompt access to shore-based medical care in port. Third, reasonably priced internet on board and, where possible, affordable or free connectivity in the port area itself.

The United States Coast Guard's Port State Control Annual Report for 2024 sets the enforcement baseline. Across 8,711 SOLAS safety exams the service recorded 82 detentions, for an annual ratio of 0.94 percent, and MLC-linked deficiencies were already among the fastest-growing categories even before the 2022 package took effect. Lloyd's Register's port state control guidance and SAFETY4SEA's breakdown of the 2024 detentions both flag crew welfare, hours-of-rest documentation and medical-access arrangements as the clauses most likely to convert a deficiency into a detention this year. Operators reading the USCG's CVC-2 detention pages can now track specific MLC citations case by case.

There is also a jurisdictional complication. USCG guidance under NVIC 02-13 and its own MLC briefing material confirms that while the United States is not a party to the convention, Coast Guard PSC teams still apply its standards to foreign-flag vessels on the basis of "no more favourable treatment" — meaning owners trading into US ports cannot assume a softer regime than they would see in a Paris MoU or Tokyo MoU inspection. For manning departments, that removes the last reason to run differentiated compliance playbooks by region.

What this means for operators: treat the 2022 MLC amendments as a live audit target, not a box-ticked certification. Fleet teams should reverify that gender-specific PPE inventories are logged per vessel, that medical-access and repatriation protocols are captured in the SMS with named shore-side contacts, and that onboard connectivity arrangements are documented against crew contracts. Expect inspectors to ask for evidence, not assurances. A single detention tied to crew welfare now travels with a reputational signal that charterers, P&I clubs and recruitment partners all read in real time — and that is a cost well above the direct delay.
