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.

National AIS Project – Environmental Statement

The US Coast Guard is seeking comments on its draft programmatic environmental impact statement (PEIS) addressing proposed implementation of the Nationwide Automatic Identification System (NAIS) project. The proposed NAIS involves installing receivers, transmitters, transceivers, repeaters, and other equipment on towers and other structures at up to 450 sites at locations along 95,000 miles of coastline and inland waterways, as well as the use of selected remote platforms


Navy Signs $72.8M Contract

Military contractor Raytheon Co. landed a $72.8m contract from the U.S. Navy to provide the Royal Australian Navy with radar equipment. Raytheon's Integrated Defense Systems unit will provide system transmitters, hardware and spares for radar systems on three Air Warfare Destroyer ships. The work will be done at Raytheon plants in Massachusetts and Rhode Island. Components of the radar system are already in use on U.S. Navy cruisers and destroyers. (Source: Ninemsn)

CMX web.jpg

CML Microcircuits has announced the launch of the new cutting-edge Marine AIS Search and Rescue Transmitter (SART) processor, the CMX7045. The CMX7045 is a highly integrated and flexible baseband processor fulfilling the needs of an AIS-SART and meeting IEC 61097-14 requirements. In addition to providing the core AIS-SART formatted data functionality, the CMX7045 incorporates a number of auxiliary operations that assist in the overall system implementation and therefore reduce component


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


CMR Debuts Gas Engine Pressure Regulator

A range of gas engine pressure regulators, which provide control of pressure levels within the fuel train on dual fuel or natural gas engines, is new for control and instrumentation specialists CMR Group. CMR’s regulators enable high-pressure gas fuel from lines and tanks to be reduced to safe and/or usable pressures for the secure and reliable operation of high horsepower engine technology used in a wide range of harsh and challenging environments including the onshore/offshore oil


Webtool HP690A Intensifier Panel

The Webtool HP690A intensifier panel is used to boost the pressure of a work fluid, usually hydraulic oil or water/glycol mixture, from a standard hydraulic power unit (HPU). The input pressure from the HPU is typically 210 bar (3,000psi), and the HP690A intensifier panel boosts this to produce an output pressure of 690 bar (10,000psi). This 690 bar output allows the operation of high pressure devices such as a Webtool subsea hydraulic cutting tool
