How Can I Learn More?

Crew Endurance Management (CEM) Pamphlet This tri-fold pamphlet may be printed out and used for informational and training purposes.

The CEMS Guide for Maritime Operations (Spanish Version) released January 2003.  The guide gives an overview of the CEMS program and explains the scientific research and tools behind it. The guide is organized into five sections:

  • An overview of CEMS,
  • An example showing how to implement CEMS onboard a commercial vessel,
  • Details on how to manage the "Red Zone",
  • Tips on controlling maritime related performance stressors, and
  • Suggestions showing how an organization can implement CEMS.

Addendum to the Guide for Maritime Operations (Spanish Version) released September 2005.  The addendum aims to supplement the original Guide for Maritime Operations with additional details and discussion in a step-by-step format.

The Navigation and Vessel Inspection Circular (NVIC) 02-08, dated March 21, 2008, provides guidelines for vessel owners, operators, third-party auditors, Coast Guard personnel and others to assess a company's or vessel's CEMS program. Enclosures in the NVIC provide a discussion of the essential implementation steps, risk factors, and the role of the CEMS Coach. Lastly there is a job aid/checklist provided to aid an evaluator in assessing an organization's CEMS program.

CEMS Demonstration Project, Report to Congress  Under the Coast Guard Authorization Act of 2004, Congress directed the Coast Guard to report on the results of a demonstration project involving the implementation of CEMS on towing vessels. The purpose of the demonstration project was to show that CEMS is feasible, effective and sustainable. The project was completed in the Summer of 2005 and subsequently delivered to Congress on March 29, 2006.

Training Tools

These tools are distributed to those individuals attending Crew Endurance Coaches Training for use in education and risk assessment efforts:


CEM Self Sustaining Workshop (SSW). Computer software that enables trainers and operators alike to learn the basics of CEM in an interactive, self-paced style. Considered the encyclopedia of CEM, it is designed to help Coaches with education efforts within their vessels and companies. It is distributed to all who attend Crew Endurance Coaches Training.

Decision Support Tool (DST). CEM implementation tool that enables maritime operators to assess 15 Crew Endurance Risk Factors and subsequently develop crew endurance plans to address those areas needing improvement.

Crew Endurance Training Tool (CETT). This tool is provided to Crew Endurance Experts to help them train new Crew Endurance Coaches. The CETT provides Experts with a presentation that follows the course outline laid out in the Coast Guard accepted course for CEM.

Where Was CEM Developed?

The Coast Guard Research and Development Center in Groton, Connecticut developed CEM as part of its Human Error Reduction/Fatigue Research Effort.

How is CEM Being Implemented?

The Human Element and Ship Design Division at Coast Guard Headquarters promotes deployment of CEM through partnerships with various maritime industry groups such as the American Waterway Operators AWO) and the Chamber of Shipping of America (CSA).
