Hi, at the moment FME support the OGP P1/90 format, and this has now been replaced with the OGP P1/11 Geophysical position data exchange format. Suggest that FME implement this new format as well
"Originally released in 2012 to replace the UKOOA P1/90 and P2/94 formats, Version 1.1, released in August 2018, incorporates industry feedback from the first release and provides greater flexibility – without changing the fundamental format structure. For example, the format now enables the recording of land and OBC formats and additional peripheral sensor, or QC data. It also includes enhancements such as: handling channel grouping, ‘virtual’ position objects such as mid-points, global pre-plot attributes, event-based attributes, receiver and source relation records."
