Bunker checklists
One of the main objectives of the working group was to create harmonized bunker checklists for known bunkering scenarios. These checklists reflect the extra requirements of ports with regard to bunker operations of alternative marine fuels in or near their port environment. By using bunkering checklists, a high level of quality and responsibility of the bunker operators can be obtained.
Implementing harmonized bunker checklists in ports will also be of great benefit to the vessels (and their crew) bunkering in other ports because it will reduce the potential confusion caused by having to comply with different rules and regulations in different ports.
The Clean Marine Fuels working group has developed checklists for the following types of bunkering:
Ship to Ship checklist
Within the IAPH Liquefied Gas bunker checklist series, the Clean Marine Fuels working group provides a checklist for Ship-to-Ship bunkering of liquefied gasses as a marine fuel in a port. For example, Liquefied Natural Gas (LNG), Liquefied Biogas (LBG), and Liquid Hydrogen (LH2).
While most fuels have alternative Ship-to-Ship checklist versions tailored to specific bunkering scenarios, only one exists for Liquefied Toxic gasses, like Ammonia. Due to limited experience with this fuel, more project-based operations are needed to create additional versions.
- Version A. It has been developed specific for project-based bunkering of vessels alongside a quay where the site operator is fully engaged in, and has a shared responsibility for, the safety of the STS bunkering.
IAPH recommends that terminals should be involved in the process to enable and ensure safe bunker operations at their berths.
The LG STS bunker checklist is a safety tool on an operational level. Port authorities or other competent authorities should acquaint themselves, that terminals are also involved on a system safety level. This way ensuring safe bunker operations of liquefied gas as a marine fuel by having terminals perform the correct procedures in both preparatory and operational process states.
Truck to Ship checklist
The Clean Marine Fuels Working Group has not yet established a checklist for Truck-to-Ship bunkering of liquefied toxic gases, such as ammonia (NH3), in a port.
Development of a Truck-to-Ship version is scheduled to commence in 2026.
A checklist for Ship-to-Ship ammonia bunkering can be found here.

The checklists contained in this section are for general use in order to maintain appropriate safety levels when bunkering liquefied gas as a marine fuel in situations to which these checklists apply. If you would want to use these checklists for inclusion in the rules, requirements and/or guidelines applicable in your area of responsibilities, you are free to do so provided the following conditions are met:
- The existing text of the questions may not be changed nor may questions be added.
- However, where in view of local circumstances, it is considered that certain questions are not appropriate, these questions may be omitted in full only and the IAPH Administrator should be promptly informed of such action by contacting us here.
- On each page of your version of the checklist, the source “IAPH” and the IAPH logo should be included in an appropriate position.
- Translations have been authorized.
