Pressure Switch News

USCG Marine Safety Alert 05-12

Pressure Switch Location for Fixed Fire Suppression Systems Where's yours located? This safety alert addresses the location of fire suppression system pressure switches aboard vessels. These critical components sense the activation of the system and then electrically secures the ventilation systems operating in the protected space. Securing the ventilation is essential in extinguishing a fire onboard a vessel. It assists in isolating the fire within the space, minimizes the introduction of additional oxygen to fuel the fire and prevents the loss of fire suppression agents from the space.

Emergency Shutdown System Gives Peace of Mind

ESRS Engine Shutdown System from Sea-Fire

In the event of an engine room fire, once the fire suppression system is engaged it's critical that engines, generators and fans are shut down quickly. This both minimizes damage to equipment and helps contain the extinguishing agent within the compartment it's protecting. The ESRS Engine Shutdown System from Sea-Fire automates this procedure using microprocessor technology, in a simple plug and play design. ABYC requires automatic equipment shutdown if there is more than one air change per minute within the engine compartment.

USCG Marine Safety Alert: Air Receivers & Relief Valves

This Safety Alert addresses safety issues relating to air receivers on Uninspected Towing Vessels (UTV), but may apply to air receivers on any vessel. Air receivers, regardless of specific use onboard a UTV, contain extreme amounts of potential energy; an uncontrolled release of this energy may lead to serious injury, death and catastrophic vessel damage. Although this issue involves basic safety and good marine practice, too many related problems have been recently discovered. Not long ago, an air receiver unexpectedly ruptured with terrible results onboard an UTV on the Upper Mississippi River. A crewmember was seriously injured and paralyzed.

Marine Safety Alert: Propulsion Loss, Fuel Switching

Ships switch fuel oil from residual fuels to distillate fuels in order to reduce emissions. The Coast Guard expects ships will switch fuel more frequently to comply with new emission reduction regulations. When switching fuel oil, some ships have experienced propulsion losses linked to procedural errors or fuel oil incompatibility. API developed a paper titled “Technical Considerations of Fuel Switching Practices” that discusses problems that lead to propulsion loss while switching fuel. It is available at http://marineinvestigations.us. This document may be useful to vessel owners, operators, and engineers interested in preventing fuel system failures and propulsion casualties while meeting current and future exhaust emission control requirements.

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.

Gardner Denver Water Jetting Systems Now Offers TLE

Gardner Denver Water Jetting Systems now offers its customers the TLE - Trans Line Exchanger Cleaner. This lightweight machine has been developed to clean vertical trans line exchangers in furnaces and other vertical bundles. It consists of two air motors: one to feed the hose and one to retract the hose. aluminum alloy, which can be separated by 4 small air cylinders, for quick-changing of the high pressure hoses. The hoses are moved by two continuous chains with polyurethane blocks, which are powered by the air cylinders. The TLE is small, light and easy to operate. The operator manipulates the switches on top of the unit to drive the hoses. Two handles can be fixed in several positions to suit the operator. A balancer with guides for the hoses is also available.

Insurers Should Control Ship Classification System: Broker

Insurers should control the ship safety classification process in the light of weaknesses exposed by the Erika’s loss, a senior tanker broker said. Insurance companies should hold the mandate over who inspected vessels’ structural conditions and passed them as safe, an official at Marinav Shipping and Trading said. Since insurers pay out the claim, it is therefore in their best interest to ensure that the vessel is maintained so that risk is minimized, the broker said. The current system is flawed because ship owners appoint the inspectors and can apply pressure to receive “flexible” treatment in return for retaining their business, he said…

Fleet Growth Weighs on Product Tanker Earnings

Photo: Alex Sergienko

Healthy returns enjoyed by the product tanker market in recent years are under threat as impending fleet growth is expected to reduce the sector’s earnings over the medium term, according to the Product Tanker Market Annual Report 2015 published by global shipping consultancy Drewry. The widespread switching of trade by product/chemical tankers (also called “swing” tankers) from chemicals to refined products has resulted in rapid growth in the product tanker fleet, which has expanded by 11.4 million dwt through 2012-14 (of which 8.2 million dwt is attributable to switching of tonnage).

Offshore Workboat Fire Safety

A Novec 1230 gas suppression system provides a unique, Class-compliant and effective margin of safety for an offshore dive support vessel. Despite the recent drop in oil prices, the marine sector remains extremely busy supporting the oil industry, and this will always remain the case. The squeeze on contractual pricing and labor is a recent issue caused by that drop in oil prices. Fortunately, the sector is led by legislation in the form of IMO/SOLAS regulations and respective Flag State requirements which are controlled by regulatory authorities such as DNV…

Aegean Bunkering Pte Ltd on Friday said it had this week left the world's largest marine fuels market in Singapore after handing back its supply and craft operator licences. The company had announced in October that it would halt physical supply operations in Singapore by January amid heightened commercial pressures after the city-state adopted tougher bunkering procedures. Aegean Bunkering, headquartered in Greece, was last year ranked the 20th largest marine fuels supplier by volume in Singapore from a total of 55, data from the Maritime and Port Authority of Singapore (MPA) showed.

USCG Alert: Compliance with MARPOL Requirements

The Coast Guard has confirmed several reports it has received stating that main engines may not attain the expected speed when using ultra low sulfur fuel oil. The Coast Guard has revised its list of recommendations to vessel owners and operators about the importance of establishing effective fuel oil changeover procedures to comply with MARPOL Annex VI emission regulations. Ensure fuel oil switching is accomplished outside of busy traffic lanes and the ECA. Generally the ECA is 200 nm from the North American Coast and 50 miles from the U.S. Caribbean coast (e.g., the Commonwealth of Puerto Rico and the U.S. Anticipate that there may be many technical challenges for operators when beginning to use ULS fuel oil as a matter of routine and compliance.
