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…

American Sensor Technologies, Inc. (AST) has achieved ATEX certification of its Explosion Proof Pressure Transmitters for Class I Zone 0 Exd hazardous locations. The added approvals enhance the ability for equipment manufacturers to specify AST pressure transducers as the sensors can now operate in both North America and Europe. AST Explosion Proof Pressure Transducers are commonly used in upstream and offshore applications where safety, reliability and performance are crucial. Additionally, the AST4300 Non-Incendive Rugged Pressure Transmitter Series is qualified as ATEX Class I Zone 0 Exd and the AST43LP Low Presssure Non-Incendive Pressure Sensor Series holds a ATEX Class I Zone 2 Ex nA rating. Each are also certified by Sira for Class I Zone 2 Ex nA IIC T4 Gc.

Roy Dunlap invented a mechanical  pressure switch that prevented oil tanks from overflowing and founded SOR Inc. SOR® founder Roy Dunlap leveraged the static-o-ring (SOR) technology to invent a highly accurate mechanical pressure switch that helped prevent the overfilling of oil tanks. This simple but innovative design resulted in a switch of flawless accuracy that would change the oil & gas and power generation industries forever. The static-o-ring pressure switch was developed…

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.

Ballast Water Treatment: Optimarin lands NOK 100 Million fleet retrofit contract with Saga Shipholding.

Exceptional Flow with Consistent Water Pressure. Jabsco, a recognized marine pumps and waste systems firm, has announced the new Par-Max™ Plus Series water pressure pumps – available in 4.0, 5.0, and 6.0 GPM models and provide exceptional flow and consistent water pressure to easily handle the demand of multiple outlets at one time. The Par-Max Plus patented co-injected molded diaphragm and larger heavier duty motor brushes significantly extend pump life up to 50% longer than previous models.

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.

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.
