New US Ballast Water Research Lab Opened

Traveling across the globe from port to port, the U.S. Navy fleet transports sailors and Marines, aircraft, and supplies. Unfortunately, ships can also unintentionally transport stowaways, small organisms which live in ballast water. Most people would not look at small organisms like mitten crabs or zebra mussels and think they are a major threat to the environment – and in their natural habitats they pose no threat. But what happens when these organisms are introduced into a new ecosystem? According to Rachel Jacobs, a chemical engineer in the Wastewater Management Branch at Naval Surface Warfare Center, Carderock Division, the results of introducing non-native species into a new environment can be disastrous for the ecosystem…

Shock Test Machine Saves Navy Big Bucks

The Navy's new Deck Simulator Shock Machine (DSSM) improves shipboard electronics reliability while reducing testing costs as equipment evaluations began in Philadelphia, saving the Navy $75,000 per test, as it meassures the effects of simulated underwater explosions on electronic equipment, informs Naval Sea Systems Command. The mammoth machine evaluates state-of-the-art, vibration-sensitive electronics cabinets weighing up to 1,500 pounds on shock isolation mounts. One of two such machines worldwide, the mechanism sits on 22,000 pounds of steel and concrete and records the effects of simulated underwater explosions on electronics equipment.

Installation of Dry Flexible Coupling on USS Essex (LHD 2)

Engineers at the Naval Ship Systems Engineering Station (NAVSSES), Naval Surface Warfare Center Carderock Division in Philadelphia recently oversaw the installation of dry flexible couplings on the lube oil service pumps and main feed pumps on USS Essex (LHD 2). The new couplings replace grease-lubricated versions eliminating hazardous waste and quarterly maintenance requirements for Sailors. The new couplings will run for a year on Essex before moving forward with installation on other amphibious ships. "The dry flex coupling, a device used to connect two moving parts of a system, replaced grid couplings that required more than three pounds of grease to keep each of the eight on board lubricated, " said Brett Franks, mechanical engineer and machinery alteration program manager.

Control Systems on LCC 20 Saves Fuel, Reduces Workload

Naval Sea Systems Command completed the installation of new control systems aboard USS Mount Whitney (LCC 20), April 8, which will reduce fuel usage and crew workload. Engineers from the Naval Surface Warfare Center Carderock Division - Ship Systems Engineering Station (NSWCCD-SSES) SSES installed the new control systems on a number of shipboard engineering components and are specifically designed to improve automation on the optimally manned ships. “Military Sealift Command-operated ships like the Mount Whitney traditionally have lower manning levels, therefore being able to operate many systems from one central control unit is essential,” said Matthew Douglass, Auxiliary Machinery Automation Branch head.
