Marine Safety Alert: Fuel Switching Safety

A Marine Safety Alert was issued to increase awareness and reiterate general guidance on fuel systems and fuel switching safety in an effort to prevent propulsion losses. After a noted decrease, there has been a recent increase in the number of reported loss of propulsion incidents on deep draft vessels within the Eleventh Coast Guard District. Coast Guard studies and review of marine casualties indicate that lack of maintenance and testing of certain systems, including fuel oil systems, is one of the leading causes of propulsion failures. Advanced planning and careful fuel system management are critical to safely switching fuels. This is especially important if fuel switching is not routine practice. Proper procedures, training, and maintenance are essential for vessels to safely switch between heavy/intermediate fuel oils and marine distillates. Additionally, vessel operators need to have a good understanding of their system requirements and limitations, and determine if any modifications may be necessary to safely switch between intended fuels. Managing Risk Extensive analysis of propulsion losses has revealed certain trends among vessels operating on marine distillates. In order to manage risk and improve safety, vessel owners and operators should: • Consult engine and boiler manufacturers for fuel switching guidance; • Consult manufacturers to determine if system modifications or additional safeguards are necessary for intended fuels;


Displacement Transmitters Improved

OMEGA's new output displacement transmitters have improved IP67-rated sealing coupled with polymer guides with rigid carriers. These transmitters have a less than 0.2% linearity as well as rugged stainless steel body construction making them especially accurate and reliable in wet and corrosive conditions. Output options are either direct-acting 4 to 20 mA or reverse-acting 20 to 4mA. Recommended for industrial use and automotive testing applications.

This Day in Coast Guard History – April 23

1880-Captain Jerome G. Kiah and his crew of six surfmen from the Point Aux Barques Life-Saving Station responded to a distress signal from a stranded scow in Lake Huron.  They departed their station in their pulling surfboat but the boat capsized a number of times in the icy water, eventually causing the six surfmen to perish from hypothermia. Only Captain Kiah survived the ordeal, but was severely injured from the cold water and forced to resign from the Service
