European foreword
This document (EN 18071:2025) has been prepared by Technical Committee CEN/TC 15 “Inland
navigation vessels”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2026, and conflicting national standards shall be
withdrawn at the latest by May 2026.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CWA 17540:2020.
This document has been prepared under a standardization request M/581 addressed to CEN by the
European Commission. The Standing Committee of the EFTA States subsequently approves these
requests for its Member States.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North

Introduction
Methanol also known as methyl alcohol is a polar covalent hydrocarbon fuel that can be made from non-
fossil sources and is very clean burning when compared to conventional marine fuels. Therefore
methanol is increasingly being used as sustainable fuel for vessels for environmental reasons. Its usage
is expected to expand significantly in the future. Therefore, there is a need to standardize the bunkering
requirements for inland navigation vessels to a reasonable degree, so that vessel operators have the tools
to select vessel fuel providers that meet set safety and fuel quality standards, in order to conduct
methanol bunkering operations safely.
This European Standard specifies safety requirements for methanol bunkering within the meaning of
European Parliament and Council Directive (EU) 2016/1629 of 14 September 2016 laying down technical
requirements for inland waterway vessels.
This document on the bunkering of methanol is based on research outcome of the Workshop CEN/WS
106 ‘Specification for bunkering of methanol’ in which was developed the CWA 17540 ‘Ships and marine
technology – Specification for bunkering of methanol fuelled vessels’. Next to this as a reference is used
the existing standard EN ISO 20519 ‘Ships and marine technology – Specification for bunkering of
liquefied natural gas fuelled vessels’.
1 Scope
This document specifies requirements for methanol bunkering transfer systems to and from inland
navigation vessels. The various scenarios for the bunker facility operator concern land, truck and vessel
(barge). It concerns design, dimensions and technical requirements for the transfer of methanol,
including the nozzle, connection, inner and outer flanges and failsafe features.
This document also specifies the process and procedures for the bunkering operations, as well as
responsibilities and risk assessment scope, taking into consideration the specific hazards in handling and
bunkering methanol fuel. Next to this, the requirement for the methanol provider to provide a bunker
delivery note and training and qualification of personnel involved.
This document is not applicable to cargo operations.
