Ship System and Component Manufacturers Discuss Past and Future

The Congressional Shipbuilding Caucus (CSC) co-chaired by Representatives Gene Taylor (D-MS) and Jo Ann Davis (R-VA), met with ship component manufacturers on the impact that low rates of naval shipbuilding have had on their companies and the challenges confronting the ship manufacturing industrial base. The ship manufacturers that met with the Caucus included: Mr. Craig Hansen of BWXT/ Babcock and Wilcox in Mount Vernon, IN; Mr. Walter Herr of Fairbanks Morse Engine in Beloit, WI; Mr. Roy Arnold of IMECO, Inc. in Iron Mountain, MI; Mr. Michael Stobbart of Lister Chain and Forge, Inc. in Blaine, WA; and Mr. Terry Sterling of Nelson Stud Welding in Elyria, OH. These companies manufacture nuclear propulsion system components, diesel engines, ship heating and cooling systems, ship anchor and mooring chains, and welding systems, respectively. The industry representatives highlighted their challenges in maintaining and training a workforce and their cost structure in the face of low and unstable ship production in the United States. The industry stressed the need for larger shipbuilding budgets to provide economies of scale to lower the cost of systems and components across all ship platforms. Co-chairman Gene Taylor (D-MS), Rep. Elijah Cummings (D-MD), Rep. Brad Ellsworth (D-IN), Rep. Randy Forbes (R-VA), Rep. Stephanie Tubbs-Jones (D-OH), Rep. Steve Kagen (D-WI), Rep. Michael Michaud (D-ME), Rep. Bobby Scott (D-VA), and Rep


Oil Consumption of Medium Speed Diesel Engines

Reliability and availability are of paramount importance to all users of internal combustion engines. Inherent engine design reliability must be complemented by a suitable periphery and the appropriate choice and treatment of working media such as lubricants and fuel. CIMAC Working Groups have a long tradition of preparing recommendations and guidelines for the internal combustion engine industry and its users. In performing this work


Wärtsilä-Developed Engine Undergoes Test Program

The first electronically-controlled low-speed marine diesel engine built in Japan is currently completing its test program.

Moreover, the engine provides extended flexibility over a broader load range when equipped with a VTG turbocharger


Silence on the Ship

Hatz SilentPACK is a quiet engine. Sound is reduced by up to 90 percent

A double-hulled tanker called Bernhard Dettmer refuels ships in Hamburg Harbor – power supply on board is provided by a Hatz SilentPACK diesel engine. It is end of the working day. Calm returns on board the Bernhard Dettmer, although the diesel engine is running, supplying the ship with power. There is no noise, however, because the engine is running very quietly. This is one of the outstanding features of the Hatz 4L41C SilentPACK engine
