Read more about G.R. Bowler's Callaway automation
project in The GREAT
LAKES SEAWAY REVIEW. In the first application of its kind
in the Great Lakes, the USS/Great Lakes Fleetís self-unloader, Cason
J. Callaway, retrofits a steam propulsion plant unit with an ACC
qualified automated control system.
G.R. Bowler's Scope of supply:
- Automated steam propulsion and auxiliary machinery
- Engine room, bridge, and ballast control systems
- Siemens Moore Process Automation, Advanced Process Automation
and Control System (APACS)
- Control, monitoring, alarm, trending and logging functions
- Accordance with USCG and American Bureau of Shipping rules
for ACC type certification
- ABS type-approved and tested hardware; and redundancy in systems
Benefits of G.R. Bowler automation architecture:
- All propeller commands are controlled directly from the bridge.
- Engine room watch requires only one worker.
- Capital investment cost is lower compared to diesel re-powering.
- Maintenance cost of the steam turbine is lower compared to
- NOx stack emissions of steam power are lower compared
- Fuel consumption is reduced by 100-120 gph at lake speed.
System Update: April
2001: The system has been operating flawlessly, without downtime,
and has successfully reduced both fuel and manpower costs.
