Some mariners hold radar course completion certificates that have expired, or will expire before July 22, 2019. Under strict interpretation of regulations, these mariners may be required to provide a course completion certificate to prove the validity of their existing radar observer endorsement. This potential action would go against the purpose and intent of this rulemaking.
Mariners will be considered in compliance with radar observer requirements if they hold a valid Merchant Mariner Credential containing the appropriate endorsement as Radar Observer. Mariners should not be required to provide training certificates to show their Radar Observer endorsement is current and valid.
This policy letter will expire on July 22, 2019, which is the implementation date of the Amendments to the Marine Radar Observer Refresher Training Regulations final rule.

The National Maritime Center posted a bulletin to alert mariners that due to a continued backlog of credential applications and increased net processing time of both mariner credential applications and medical certificate applications caused by the lapse in appropriations and shutdown of National Maritime Center operations, the following updated actions are being taken:
Merchant mariner credentials (MMC) and medical certificates (national endorsements only) that expire in December 2018, January 2019, February 2019, March 2019, April 2019, May 2019, June 2019, or July 2019 are extended as valid until August 31, 2019. Mariners who are actively working on expired credentials that meet the expiration criteria must carry the expired credential with a copy of the attached letter.
This extension does not change the time frame during which a credential may be renewed. A credential may be renewed at any time during its validity and for 1 year after expiration based on the expiration date printed on the credential.

An Inspected Towing Vessel (ITV) pushing a loaded tank barge experienced a loss of steering and subsequently ran aground, Sept. 25, 2018. The marine casualty investigation determined the initiating event to be the port shaft propeller nut wedged into the rudder, which prevented the free and full movement of the steering gear. (Figure 1)
Contributing Factors and Analysis.
The investigation identified the initiating event causal factors to be a material failure of the port shaft propeller nuts locking strap (missing), the lack of a secondary securing mechanism (second nut/cotter pin) on the port propeller nut, and an inadequate corrosion mitigation preventative maintenance program. Visual analysis of the starboard shaft locking strap noted significant deterioration of the locking mechanism (Figure 2), requiring immediate replacement. Based on the analysis of this casualty, marine inspectors inspected the locking nut straps of several other ITV’s during scheduled dry-dock exams, which showed similar corrosion issues.
The Coast Guard recommends the following preventative measures:
Review company corrosion prevention systems/programs. If necessary, engage with a corrosion specialist from the American Boat and Yacht Council and/or National Association of Corrosion Engineers.
Ensure adequate primary and secondary propeller shaft securing devices (cotter pins, double nut, locking strap, etc.) are in place at all times, with consideration given to vessel operations and environmental conditions.
Inspect propeller fasteners routinely/during every dry-docking and replace in accordance with manufacturer’s instructions.
The Coast Guard issues findings of concern to disseminate information related to unsafe conditions identified as causal factors in a marine casualty and that may cause a similar casualty on other vessels. Findings of concern are intended to educate the public, state, or local agencies about the conditions discovered so they may address the findings with an appropriate voluntary action or highlight existing applicable company policies or state/local regulations.
These findings of concern are provided for informational purpose only and do not relieve any domestic or international safety, operational, or material requirements.
