The Wellness at Sea Conference was held in Singapore this last week: http://seamenschurch.org/article/wellness-at-sea-conference-singapore-january-2017
This may be the part that would interest most here on this forum:
Another panel looked at the impact of modern communications on seafarer wellbeing. There is a debate in the industry about the value of restricting seafarers’ access to social media. This is an important issue given the perception among seafarers that access to the Internet is akin to a human right, but this must be balanced against cyber-security risks. One speaker pointed out that today’s seafarers have a need for access to the Internet and that restrictions are generally ineffective and counterproductive.
