The LNG/C Matthew
The LNG/C Matthew (originally El Paso Howard
Boyd) was built in 1978 by Newport News Shipbuilding. The new
owners, Cabot LNG Inc., recognized the need to replace the engine
roomís obsolete 1970s-vintage hardwired electronic control systems.

G.R. Bowler's Scope of supply:
- Safety, reliability, and twenty years of serviceability for
its new systems
- ABS type-approved, Siemens Moore, APACS systems hardware and
ProcessSuite HMI software
- Bridge throttle control, monitoring, and alarm and data management
functions for the main propulsion machinery and engine room auxiliaries
- Seamless architecture of control hardware and communications
software suited for the LNG vesselís complex, dual-fuel strategies
Benefits of G.R. Bowler automation architecture:
- Dual-fuel systems (heavy, #6 fuel oil and LNG boil-off):
- maximize efficiency of the combustion process (dual-fuel,
- fuel the vesselís propulsion boilers, and
- provide an added safety feature.
- Troubleshooting and adjustment of plant operations
is streamlined by real-time, comprehensive observation and graphing
of plant variables (on monitor screens).
- Main turbines, total systems observation, and access
to selected alarms are controlled from the bridge.
- Systems can be monitored and controlled from shore.
- New officers find the superior operator interface
and display graphics easy to understand and use.
System Update: January
1999: Commissioning is complete and Cabot LNG Shipping is currently
transporting liquefied natural gas aboard the LNG/C Matthew from Point
Fort in Trinidad to Boston, Massachusetts on a regular schedule. (The
ship is now owned by Tractebel and operated by Hoegh Fleet Services.)
