The National Transportation Safety Board (NTSB) has released its annual compendium of marine accidents and the lessons learned from them.

“Safer Seas Digest 2015,” available in print and on the NTSB’s website, ntsb.gov, examines 29 major marine casualty investigations the agency closed in 2015.

“’Safer Seas Digest 2015’ represents our continuing commitment to sharing the lessons that we learn through our investigations,’’ said NTSB Chairman Christopher A. Hart. “Many marine accidents can be prevented when crews know of and respond to safety issues early and when crews work together effectively in the event of a crisis.’’

The 72-page report lists some of the lessons learned from the investigations, such as better voyage planning, the need for effective communications and recognizing the peril of crew fatigue.
