IMO Polar Code

The International Maritime Organization (IMO) has introduced a mandatory Polar Code to enhance safety and protect the fragile ecosystems of the Arctic and Antarctic regions.

With amendments entering into force on 1 January 2026, the Polar Code now applies to a wider range of vessel types, including certain non‑SOLAS vessels.

If your ship operates in polar waters – under SOLAS, MARPOL or newly included categories – it must comply with the applicable sections of the Polar Code.

What is the purpose of the Polar Code?

The International Code for Ships Operating in Polar Waters, commonly called the Polar Code, is a mandatory framework overseen by the IMO. It ensures ships:

• Can operate safely in extreme cold
• Are designed and equipped for ice, darkness and remote conditions
• Follow strict environmental requirements
• Carry trained and competent crew for polar operations

These requirements are mandatory through amendments to SOLAS, MARPOL and STCW.

Who must comply?

SOLAS‑certified ships, if operating in polar waters, must comply with:

• Part I‑A Safety Requirements
• Part I‑A Manning & Training Requirements

MARPOL‑certified ships are required to comply with:

• Part II‑A Environmental Protection Requirements

Non‑SOLAS ships (effective 1 January 2026)

The following vessel categories are now subject to mandatory Polar Code requirements when operating in polar waters:

• Fishing vessels of 24 metres in length and above
• Pleasure yachts of 300 GT or greater (not engaged in trade)
• Cargo ships between 300 and 499 GT

These vessels only need to comply with Part I‑A Safety Requirements for:

• Safety of Navigation (Ch.9-1)
• Voyage Planning (Ch.11-1)

These vessels are not required to apply for a Polar Ship Certificate, nor must they establish a PWOM (unless mandated voluntarily by the administration).

Note:
For non‑SOLAS vessels outside the categories listed above, but which hold a MARPOL certificate, only the Part II‑A Environmental Protection Requirements of the Polar Code apply.
