General Dynamics, NNS To Cooperatively Build New Attack Submari

Electric Boat Corp., a subsidiary of General Dynamics, and Newport

News Shipbuilding (NNS) have — "at the urging of the U.S. Navy" — reached a teaming agreement to cooperatively build the Navy's new attack submarine, NSSN.

Under the terms of the agree- ment the companies will be equal team members in construction of each of the first four submarines in this new class. This requires an alteration to existing law, con- tained in last year's Defense

Authorization Act, which directs independent submarine construc- tion by the two yards.

Electric Boat will perform final assembly, testing, outfitting and delivery of the first and third sub- marines. For all four submarines,

Electric Boat will construct the engine room modules, command and control modules, and seven other sections of the ship. Electric

Boat will continue its role as lead design yard. NNS will perform final assembly, testing, outfitting and delivery of the second and fourth submarines. For all four

Marine Electronics Merger

Creates New Player

Simrad and Kongsberg

Norcontrol, two Norway-based electronic equipment suppliers, merged on January 1 of this year to form Kongsberg Maritime.

Kongsberg Norcontrol's primary market is merchant shipping, and its systems are reportedly installed on more than 3,000 ves- sels worldwide. The company is also a supplier of vessel traffic management systems (VTS).

Simrad manufactures electronic equipment for the offshore oil and ocean science sectors as well as for fishing craft and yachts.

Kongsberg Maritime has report- edly won a shuttle tanker order, which will be built by Astilleros

Espanoles Sestao, and will com- bine Kongsberg Simrad's dynamic positioning and process control with Kongsberg Norcontrol's inte- grated bridge system.

Ashland Debuts New

Combustion Analyzer

Ashland Chemical's Drew

Marine Division has introduced the Diesel Performance Analyzer (DPA), a PC-based cylinder and injection pressure monitoring sys- tem designed to facilitate timely, accurate diagnosis of engine condi- tions. DPA is for use on all types of two-stroke engines, as well as four- stroke medium-speed engines with a maximum of 1,500 rpm. The sys- tem uses a PC or laptop, with either MS.DOS or Windows ver- sion 3.1 or 95 software. Software can also be customized to fit specif- ic needs. Data collection for mea- suring combustion pressure is accomplished with a pressure sen- sor and two permanently fitted inductive magnetic sensors that obtain rpm and crankshaft angle data from the flywheel.
