As a result of the COVID-19 pandemic, it has not been possible to hold face to face meetings of our members for the last two years, due to the challenges involved with international travel.


An online meeting was held in December 2021 to review ISOA’s recent activities, and its plans for the coming year.​

The next members’ meeting has been tentatively arranged for June 2022 in London, but this will be confirmed nearer the time, dependant on travel restrictions.


ISOA meetings normally adopt the following format

  • An evening social event for ISOA members and guests

  • A formal meeting, comprising

    • Review of ISOA surveys among its members, and other current work items

    • Discussion on industry topics (including regulatory developments, technical and operational standards, newsworthy issues such as piracy

  • Presentations by external speakers/industry experts on topics of general interest to members


Annual Personnel Accident Surveys


ISOA conducts an annual Personnel Accident Survey to which its members contribute. The intention of the survey is to:


  • Monitor trends in levels of accidents on offshore support vessels

  • Analyse accident data according to a variety of parameter (including activity being undertaken, type of injury etc.)

  • Enable members to benchmark their own performance against the ISOA average, and take appropriate steps to improve performance.


The aggregate results are circulated to all ISOA members, with individual company data being treated as confidential.

Staff Numbers Benchmarking Survey

ISOA has instigated a survey is to assess and compare the various levels of vessel and shore based staffing levels across the OSV sector, with specific focus on:

  • Shore based General and Administrative Personnel

  • Crew levels on different OSV vessel types


Data is aggregated by region as well as globally.


Members are able to compare their own staffing levels with the averages compiled for ISOA as a whole.

Members are updated on developments at their meetings, and by circulars between meetings.


Where appropriate, ISOA provides input on behalf of its members to the development of regulation and standards.
