Security levels: what they mean and what changes

PSA-M1 · The security framework · PSA-M1-A How the ISPS Code, security levels and the four levels of security training fit together.

Three levels, set by governments, not by the yacht. **Your job is to know the current level and what it changes for you.**

Where this sits

Governing: SOLAS XI-2; ISPS Code Part A section 2 and Part B; gov.uk maritime security guidance. Builds on: L1.1.

The three levels

Level Meaning What it feels like on board
1: normal Minimum appropriate protective security measures maintained at all times Controlled gangway, ID checks, restricted areas locked, deliveries checked
2: heightened Additional protective measures for a period, because of a heightened risk of a security incident More frequent checks and patrols, fewer access points, more searching, more escorts
3: exceptional Further specific measures for a limited period when an incident is probable or imminent, even if the target cannot be identified Access restricted to essential people, possible suspension of operations, instructions from government

The ship security plan (SSP) sets out what the vessel does at each level. You will not see the whole SSP; it is confidential. The SSO tells you what your part is.

Who sets the level

Security levels are set by governments, not by the master or the owner. For UK ships, the Department for Transport is responsible for maritime security policy, and the MCA implements the ISPS Code on UK ships.

  • At sea, a ship works to the level set by its flag state.
  • In port, or before entering port, a ship complies with the port state's level if that is higher than the level set by its flag (SOLAS XI-2).
  • The ship can always choose to operate at a higher level than the one set, and the SSP may say when.

CAUTION: Levels differ ashore The port facility may be at a different level from your yacht. Where the two differ, or after a security incident, a Declaration of Security may be agreed between the ship and the port facility setting out who does what.

What changes for you at level 2

Exact measures depend on the SSP, but typical level 2 changes are:

  • access: fewer gangway or tender landing points; every person identified and logged; visitors escorted;
  • searching: a larger share of people, bags, stores and vehicles searched;
  • patrols: more deck rounds, especially at night and on the waterside;
  • restricted areas: bridge, engine room and other spaces locked or guarded;
  • deliveries: checked against orders before loading, with no unexpected deliveries accepted;
  • communications: radios checked, call-in schedule for patrols.

At level 3, expect instructions from the authorities and a sharp reduction in movement on and off the vessel.

Maintaining awareness

The third Security Awareness competence is about vigilance. Complacency is the enemy, particularly at level 1, when nothing has happened for months and you know everyone on the dock.

  • Treat every check as if it matters.
  • Know the level: many yachts post it at the crew entrance and gangway.
  • If you are unsure what a change means for you, ask the SSO.

TIP: Level changes at night Level changes can arrive at any hour. If you are the night watch, you will often be the first crew member to act on one. Know where the SSO's cabin is and how to wake the duty officer.

scenario · core

You are the gangway watch on a 90 m yacht in port. The SSO tells the crew the ship has moved to security level 2. A delivery driver you know well arrives with flowers and asks to walk them straight up to the guest deck as usual. What do you do? (a) Let him through because he is a regular (b) Refuse all deliveries until level 1 is restored (c) Ask a guest to decide (d) Apply the level 2 measures in the SSP: check identity and the delivery, search or escort as required, and do not relax control because you know him
