The Maritime Technologies Forum (MTF) has unveiled comprehensive guidelines for conducting qualitative risk assessments specifically HAZID and HAZOP for ships using alternative fuels. As the maritime sector accelerates its decarbonisation efforts under the IMO’s 2023 GHG Strategy, these guidelines aim to support safer adoption of new fuel technologies across the global fleet.
Supporting the Transition to Alternative Fuels
Alternative fuels play a crucial role in reducing greenhouse gas emissions from international shipping. While the IMO has already issued several guidelines for designing and operating ships capable of using such fuels, many of these fuels are still subject to the Alternative Design and Approval process until mandatory regulations come into force.
Under this process, ship designers and operators must demonstrate through qualitative risk assessments that alternative-fuel technologies offer safety levels equivalent to conventional fuel systems.
Existing references such as MSC.1/Circ.1455 and IACS Rec. 146 continue to serve as baseline frameworks. However, with rapid technological advancements and increasing adoption of fuels like ammonia, hydrogen, methanol, and advanced biofuels, MTF recognized the need for updated and expanded guidance to cover a broader range of applications.
New Guidelines for HAZID and HAZOP Implementation
MTF’s newly published report outlines clear procedures for carrying out HAZID (Hazard Identification) and HAZOP (Hazard and Operability) studies for alternative-fueled vessels.
Key features include:
-
Qualification requirements for specialists conducting the assessments
-
Step-by-step methodology for both HAZID and HAZOP processes
-
Required input documents and preparation checklists
-
Risk criteria and reporting standards
-
Guidance on identifying hazards and implementing safeguards
These guidelines were formally introduced at the MTF Seminar on Safe Maritime Decarbonization at Europort on November 6, 2025. Industry leaders participating in the seminar emphasized the importance of such tools to ensure consistent evaluation practices, transparency, and stakeholder confidence especially as more newbuilds and retrofits adopt alternative fuel systems.
With alternative-fuel vessels set to become increasingly common, MTF’s new guidelines provide timely and practical support for ship designers, operators, and regulators. By standardizing qualitative risk assessment practices, the framework strengthens the industry’s ability to identify hazards, implement safeguards, and ensure safe maritime decarbonisation on a global scale.
