MSC.560(108) and PSSR: What every seafarer should know in 2026

Ask seafarers or crew managers what they are talking about right now, and the same subject keeps coming up: the STCW Personal Safety and Social Responsibilities (PSSR) course.

On paper, it is one of the most fundamental parts of maritime training. In practice, it has become one of the most debated — and most misunderstood — requirements in the industry.

A course focused on behavior, not equipment

When most people think of safety training at sea, they picture firefighting drills or survival suits. PSSR takes a different angle: it places people, not equipment, at the centre — because people are where safety begins.

The course introduces seafarers to what working onboard actually looks like: how vessels are organized, how responsibilities are distributed, and how each individual’s behavior shapes collective safety. Many people, one crew. It covers communication, teamwork, hazard awareness and procedures, alongside fatigue, stress and the human factors that so often lie behind maritime incidents.

Put simply, PSSR answers a single question: how do you behave safely on a ship? With multinational crews, strict hierarchies and demanding working conditions, the answer is far from obvious — which is exactly why the course exists.

How it became part of STCW

The requirement is rooted in the IMO’s STCW Convention. Before STCW existed, training standards varied sharply from country to country, producing predictably inconsistent safety outcomes. PSSR was made part of Basic Safety Training so that every seafarer shares a minimum understanding of safe conduct onboard.

It stands alongside firefighting and first aid, but in many ways underpins them: even the strongest procedures break down when people fail to communicate, cooperate or take responsibility.

The shift the industry cannot ignore: MSC.560(108)

That changed with IMO Resolution MSC.560(108), which came into force on 1 January 2026 and updated the corresponding competence table in the Annex. On the surface, it looks like another routine regulatory update. In reality, it marks a meaningful shift in how the industry defines safety.

For the first time, PSSR explicitly covers the prevention of and response to violence and harassment, including bullying and sexual harassment. Safety at sea is no longer defined only in physical terms — fires, collisions, equipment failure — but in social and psychological terms as well. 

The way people treat each other onboard is now formally recognized as a safety matter. Concerns about crew welfare, mental health and onboard culture have been mounting for years; MSC.560(108) finally embeds them in the regulatory framework.

Where the confusion begins

Since the amendment came into force, PSSR has shifted from a “tick-the-box” course into something far more visible and far more scrutinized. Training providers have refreshed their content, companies are revisiting internal policies, inspectors are looking more closely, and seafarers are beginning to ask questions of their own.

Among experienced crew, one reaction comes up again and again: “I’ve been sailing for years – do I now need to take this course again?” In most cases, the answer is no. Seafarers who completed PSSR before 2026 generally remain compliant, and their existing certificates are still valid.

The reality, however, is not always that straightforward. PSSR has not always been delivered as a standalone course – some seafarers received equivalent training onboard or as part of broader programs, with inconsistent documentation as a result. Enforcement also varies from one flag state to another. Combine crews trained at different times under different interpretations, and uncertainty becomes inevitable.

Shipowners are nonetheless expected to keep their crews informed and up to date on new regulations. Taking an updated PSSR course is often the most practical way to do exactly that.

The debate: what belongs on the certificate?

One of the liveliest discussions is not about the new PSSR content itself, but about how it is documented – specifically, whether certificates should explicitly reference MSC.560(108). The regulatory answer is clear: there is no formal requirement in the STCW convention to include such a reference.

The amendment updates the competence standards; it does not prescribe certificate wording. Yet the question refuses to disappear – because the industry does not operate on regulations alone. And individual flag states may (and do) mandate such wording on certificates, in order for them to be accepted in the real world.

Why implementation is not straightforward

Imagine a port state control inspection: the inspector is handed a certificate issued before 2026 with no mention of the updated requirements. Does this seafarer actually hold the new competencies?

Legally, the certificate may well still be valid – it met the requirements at the time of issue, and under STCW, PSSR certificates carry no expiry date. But many flag states and shipping companies now expect the updated training to be reflected in current documentation.

Most flag states apply the updated requirement from 2026 onwards. A number of others – Panama being a notable example – specifically require the PSSR certificate to cover the new subjects, with explicit reference text on the certificate itself, or it will not be accepted.

That is why some training providers, such as STCW.online, now include additional wording such as “as amended, including IMO Resolution MSC.560(108)”. Not because STCW demands it, but because it removes any doubt. Shipping companies tend to take a ‘better safe than sorry’ approach, and many want their crews to genuinely understand the updated expectations around behavior and onboard culture.

A phase of transition

On one side stands the formal regulatory position: existing certificates remain valid, and no specific reference to MSC.560(108) is required – a point reconfirmed by the IMO Sub-Committee on safety at its February 2026 meeting.

On the other side stands operational reality: companies, inspectors and clients want visible proof that training reflects the latest standards, and individual flag states can, and do, layer on requirements of their own. Much of the current confusion lives in the gap between the two.

What this means in practice

For seafarers, the message is largely reassuring: a valid pre-2026 PSSR certificate is generally still compliant. Employers may, however, expect crews to be familiar with the new topics introduced by MSC.560(108), and they remain responsible for ensuring that additional training is provided.

Taking the updated PSSR course – particularly when delivered online – is often the simplest way to settle any uncertainty. Flag states including Liberia and the Bahamas have already approved online PSSR courses.

For newcomers entering the profession, training already includes the updated content from day one. It is still advisable – though not formally required – to have MSC.560(108) explicitly mentioned on the certificate, in order to avoid any need for retraining later on.

For companies, the challenge lies in balancing regulatory compliance with practical clarity: making sure crews are not only certified, but also demonstrably aligned with current expectations.

A wider shift in maritime safety

The evolution of PSSR reflects a broader shift: the industry is moving beyond a purely technical view of risk towards a more holistic one, in which behavior, culture and wellbeing are treated as equally important.

MSC.560(108) does more than update a course – it reshapes what safety at sea actually means, for all the people, men and women alike, who work out there. And that is perhaps why a course that once sat quietly in the background has now moved to the centre of so many conversations.
