Livorsi Raw Water Flow System

Livorsi Water Flow Gauge

The Raw Water Flow system is a new patented system that indicates your engine’s water flow volume. This system warns you of a potential problem or danger that would otherwise not be indicated by a water pressure gauge alone, thus preventing cosmetic and structural damage to expensive exhaust headers, intercoolers and cooling systems. What is Water Flow? Water flow is a real indication of water surging through a cooling system such as: exhaust headers, sea strainers, impellers, Gen sets, intercoolers and any other marine or industrial applications that utilize water flow. Why You Need It.

USCG Issues Safety Alert

The U.S. Coast Guard issued a Safety Alert stating that a chemical tanker recently suffered a tank explosion in the Gulf of Mexico near Galveston. After stripping a tank, the tankerman opened the tank top cover and an explosion ensued, injuring the tankerman and damaging the vessel. While the investigation is ongoing, the cause appears to be that the bearings in the cargo pump failed, allowing the shaft and impeller to shift and spin against the casing. The friction caused extreme heat and possible sparks, which ignited the atmosphere in the tank. Owners and operators are advised to ensure proper maintenance of cargo pumps. Source: HK Law

Omnithruster Continues to Lead The Way

The recent award from the Japanese Defense Agency for its two newest Coastal Mine Sweepers secures Omnithruster’s position as one of the leading designers and manufacturers of advanced, low noise, shock hardened thrusters. The Omnithruster JT575AM, designed from the ground up for the Japanese Defense Agency, incorporates the patented Omniphaser noise masking system. This device uses some of the thruster’s own output to reintroduce a water/air mixture into the thruster inlet. The air bubbles compress and expand while traveling through the impeller absorbing incipient cavitation energy that normally emanates a noise. This reduction in noise is dramatic; enough in fact, for the U.S.
