FIELD SERVICES
Field services have been provided on a global basis since the formation of Propulsion Data Services.
Typical field services are:
Ship checks
for arrangement, structures, equipment installations etc are performed
as needed to meet requirements of naval architectural and marine
engineering projects. Engineers are equipped with portable computers
complete with CAD systems and diagnostic tools as necessary.
Inclining and deadweight surveys
have been performed on a wide range of craft from small boats to large
motor ships. All data is integrated into the Propulsion Engine for
in-field processing. Stability kits include inclinometers, printers,
scanners and portable computers, all battery operated, allowing tests to
be performed on a dead ship.
Sea trials are the predominant field service.
Performance evaluations are performed to determine:
If propulsion and other systems are performing to expectations.
What changes can be made to improve performance.
Baseline performance data for comparison with later events.
Data such as speed, engine
power levels, vessel trim, propeller
shaft torque and vibration levels are typically recorded. All data can
be reviewed on site. All data is stored in an HDF file for later
analysis.
Vibration investigations are unfortunately all too common. Acquisition
of data is performed using equipment such as multiple
accelerometers for modal analysis and stroboscopes for quick
inspections. Data is stored in an HDF file for review on site
and further diagnostics at a later date.
Data Logging for Simulations:
With the advent of electronic control systems for engines, gears and
other major energy consumers it is easy to log how and when an
event happens. Adding position tracking and speed using gps, propulsion system output, power
meters on generators and large electrical consumers and other points of
interest it is possible for Propulsion Data to log
system functions which can be used to understand how equipment and energy
is being used. Combined with analysis using the modeling and simulation module of the Propulsion
Engine the information can be used to define more efficient operating procedures or
to design an entirely new vessel optimized for a particular service.
