Abstract
This document presents results from contact tests to determine the influence of coastal climate on connectors for use to transfer power from shore to fishing vessel batteries.
The test objects were CCS Type 2 (DC) and Type 2 (AC).
The tests simulate about three and a half years of operation in Norwegian coastal environments (marine corrosion index 8). The resistance increases excessively for at
least one contact in all connectors exposed to salt mist. Still, most of these connectors also have contacts without excessive contact increase. In the reference group (i.e. not
exposed to salt mist), a similar excessive contact increase is not observed for any contacts. Post-mortem investigations indicate that connections are sensitive to
mechanical handling.
The results indicate that exposure to coastal climate and/or excessive manual handling can be a concern for CCS Combo 2 and Type 2 connectors. At the same time, the
recorded resistance increases were limited, and the tested connectors would not have failed due to overheating during three and a half years of operation.
