The International Maritime Organization (IMO) has recently updated its guidelines for handling “MARPOL delivered samples,” with a key change being the requirement for an increased sample size from 400 ml to 600 ml for compliance checks under the Safety of Life at Sea (SOLAS) Regulation II-2/4.2.1. This update specifically pertains to fuel oil flashpoint requirements. Starting in May 2024, suppliers will need to include flashpoint data on the Bunker Delivery Note (BDN) in accordance with MARPOL Annex VI guidelines. The formal implementation of these changes will take place with SOLAS amendments on January 1, 2026.

The IMO’s MSC-MEPC.2/Circ.18 now includes additional requirements for sampling fuel oil to determine compliance with MARPOL Annex regulations. These guidelines emphasize the importance of familiarity with sampling equipment, proper witnessing of sampling by both ship and supplier representatives, and specific measures to prevent sample contamination. Furthermore, there has been a shift in responsibility for tracking retained samples from the ship’s Master to the Company, along with the establishment of new procedures for documenting flashpoint testing.

These updates aim to enhance the accuracy and reliability of fuel oil sampling processes within the maritime industry. By increasing sample sizes, incorporating flashpoint data on Bunker Delivery Notes, and implementing stricter guidelines for sampling procedures, the IMO is working to improve compliance with SOLAS regulations and ensure the safety of maritime operations. It is crucial for all stakeholders involved in fuel oil handling to adhere to these updated guidelines to maintain industry standards and environmental protection.
