EFC Working Party 9: Marine Corrosion


Chairman: Professor Philippe Refait
Vice-Chair: Dr Paul Shiladitya
Secretary: Dr Paul Shiladitya


Objectives for the Working Party on Marine Corrosion:

The objectives of the Working Party can be defined as follows:

  1. to provide engineers, designers and materials specialists with information related to the use of materials in the marine environment;
  2. to act as or to create a platform for discussion by authorities from industry and academic institutions on materials aspects of marine corrosion;
  3. to identify and to define areas in which information is not up-to-date or not available in the required form;
  4. to identify areas in which research and development is required;
  5. to establish and maintain contacts with other workers in the same area and either co-operate with them or avoid duplication of activities.

In order to meet the objectives of the Working Party the following working methods have been decided to be used in the Working Party.

  1. Organize and participate in Workshops, Seminars and Conferences
  2. Prepare guidelines on all aspects of marine corrosion
  3. To either carry out research or simulate others to do so in areas where a lack of scientific knowledge has been shown to exist.



In the field of Marine Corrosion the important issue is the resistance of materials against corrosion in contact with seawater. In order to cover this area the Working Party "Marine Corrosion" was proposed after the International Congress of Marine Corrosion held in Cannes 1964. During the years, the Working Party has been active in several areas. In the frame of the working party literature studies have been performed on the subject of marine corrosion testing, crevice corrosion in seawater and corrosion of non ferrous metals in sea water. The Working Party has organised and supported workshops, seminars and conferences many times in its history, of which several documented in the EFC series. A round robin test at several test sites studying crevice corrosion in seawater on stainless steel was carried out in the early 1990 by the Working Party. Ten years later the working party initiated a European Commission funded project, Crevcorr, which developed crevice corrosion testing techniques that should be able to predict service performance in seawater. In this project another round robin test programme was carried out, both in natural seawater and developed new synthetic seawater with bio capacity developed during the project, the latter being a major achievement in the field of crevice corrosion testing. Not only stainless steel has been the topic for the Working Party, non ferrous metals such as aluminium and copper based alloys have been included in the activities. Since the EFC series was introduced the Working Party has been involved in six publications in the EFC series until today. Furher details of the history of the Working Party can be found in the history publication of EFC.


Work programMe:

  1. Arrange a Marine Corrosion session at EUROCORR each year
  2. Initiate work on new publications in the area of Marine Corrosion
  3. Follow the standardisation of the test methods from the "Crevcorr" project in ISO
  4. Collaboration with NACE in Marine Corrosion related topics


Call for next meeting:

The next meeting will be held during EUROCORR in Prague, Czech Republic, that is held in September 2017.

WP 9 publications:

The working party has published the follwing books in the EFC series:

  • The Corrosion Performance of Metals for the Marine Environment: A Basic Guide (EFC 63)

    Editor-in-Chief: R. Francis and C. Powell

    This guide is a joint EFC-NACE publication and has been instigated and supported by many of the members of WP9 (Marine Corrosion) of the EFC (European Federation of Corrosion) and STG44 (Marine Corrosion) of NACE International.

  • Methodology of Crevice Corrosion Testing for Stainless Steels in Natural and Treated Seawaters (EFC 60)
    A Working Party Report on the CREVCORR Project
    Edited by Ulf Kivisäkk, Bard Espelid, and Damien Féron

    Visualisation video for the disk spring set up in EFC 60, Annex B (Crevcorr) (82 MB)

    In EFC publication number 60 "Methodology of crevice corrosion testing for stainless steels in natural and treated seawaters", a method for making crevice corrosion specimens for stainless steel for seawater testing is included in chapter 4 at pages 17-20. The test method was developed in the EU partly funded project "Crevcorr" and a detailed procedure is described in Appendix B, pages 94-99. In order to visualise the assembly of the crevice corrosion specimen a short instruction video is available below: The video has been prepared by DNV Energy in Bergen, Norway.
  • Corrosion behaviour and protection of copper and aluminium alloys in seawater (EFC 50)
    Edited by D. Féron
  • Marine Corrosion of Stainless Steel (EFC 33)
  • Survey of Literature on Crevice Corrosion (1979-1998) (EFC 30)
