The LNG/C Matthew

Photo Album

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. Download more information (1 MB Adobe Acrobat file) about the LNG/C Matthew automation project. Download presentation: "UNDERWAY with PCS7/APACS OS" (7 MB/40 pages Microsoft PowerPoint file).

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, combustion control)
  •   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.)
