The United States Coast Pilot® consists of a series of nautical books that cover a variety of information important to navigators of coastal and intracoastal waters and the Great Lakes. Issued in nine volumes, they contain supplemental information that is difficult to portray on a nautical chart. Topics in the Coast Pilot include channel descriptions, anchorages, bridge and cable clearances, currents, tide and water levels, prominent features, pilotage, towage, weather, ice conditions, wharf descriptions, dangers, routes, traffic separation schemes, small-craft facilities, and Federal regulations applicable to navigation.

Safety Alert: The Best Laid Plans for Safety Are Only as Good as Their Implementation!
Safety Alert: The Best Laid Plans for Safety Are Only as Good as Their Implementation!
Recently, while a bulk carrier was at anchor off the coast of Texas, a crewmember that could not swim was put over the rail in a Bosun’s Chair to paint the vessel’s mid-ship draft marks and load lines. Unfortunately, when his shipmates on deck commenced to haul him up, the Bosun’s Chair line parted and he fell into the water. He survived the fall and attempted to swim towards a life ring that had been thrown to him, but he ultimately submerged and was lost. Other crewmembers attempted to launch a rescue craft, but it failed to operate.

Safety Alert: MAN B&W Cooling Jacket Failures Using the correct bolts is essential!
Safety Alert: MAN B&W Cooling Jacket Failures Using the correct bolts is essential!
Recently, a 738-foot bulk carrier ran aground while outbound on the Columbia River. The grounding resulted in limited damage to the vessel and no pollution or loss of cargo. This casualty occurred primarily because of cracks on the cooling jacket of a two-stroke crosshead design Mitsui MAN B&W MC-C engine. The cracks caused a loss of engine cooling water that eventually resulted in the overheating of the cylinder cover. This then triggered an automated slow-down of the engine and an unintended loss or reduction in the vessel’s propulsion and maneuverability. Although the investigation is ongoing, identical failures of the same engine type have occurred with similar results although the engines were of different piston diameters and cylinder arrangements: about two years ago a similar equipment failure contributed to a grounding on the Columbia River, and in 2012, a vessel approaching Corpus Christi, TX lost power due to the same cause and struck a jack up oil rig causing extensive damage to the rig.

Safety Alert: Be Alarmed By All Alarms Correct Steering Gear & Other Nuisance Alarms Immediately!
Recently in the Pacific North West, Coast Guard marine inspectors experienced two different circumstances involving the alarm and control system of Mitsubishi Heavy Industries steering gears onboard relatively new vessels. Although neither event resulted in a marine casualty, they serve as a reminder to the potentially dangerous results that may occur when an alarm system is deliberately ignored. A false sense of operational safety develops when crewmembers continually silence what they consider to be a “nuisance alarm,” enabling a false perception of normalcy to develop.

ACCIDENTAL RELEASE OF CO2 SYSTEM! - IMPORTANCE OF DESIGN AND TESTING OF EMERGENCY SYSTEM CONTROLS
ACCIDENTAL RELEASE OF CO2 SYSTEM! - IMPORTANCE OF DESIGN AND TESTING OF EMERGENCY SYSTEM CONTROLS
This safety alert serves to remind shoreside and vessel personnel of the importance of 1) designing and maintaining emergency systems to be logical and easily operated in high stress situations, 2) maintaining a high level of crew familiarity with emergency systems, and 3) exercising safeguards during testing to mitigate the risk of human error or system malfunction. Although regulations prescribe standards for safety systems aboard vessels, installations particularly those onboard uninspected vessels, can vary dramatically.
