Full Scale Trials |
Oceanic maintains an active field trials team offering an independent assessment
of vessel performance and providing a one-stop service for trials planning,
logistics, instrumentation and acquisition, management, execution and reporting.
Oceanic can also provide specialized support (ice characterization for example)
to an external team.
Projects have included ship performance trials, vibration analysis, icebreaker
correlation trials, seakeeping trials and maneuvering studies. Oceanic engineers
have participated in USCG Polar Sea ice-propeller interaction studies, ice performance
trials of the Healy, and CCGS Sir John Franklin correlation program.
Typical trial measurements may include:
- Vessel speed and position (GPS)
- Propeller thrust, torque, pitch, rpm and power
- Rudder settings
- Hull and propeller roughness surveys (BSRA roughness)
- Environmental conditions
- Wind speed and direction,
- Wave height,
- Current velocity,
- Ice thickness, temperature, salinity, density and flexural and compressive
strength.
- Air temperature
- Water temperature and salinity
- Bathymetric data
- Machinery and hull vibration (acceleration, spectral analysis)
- Seakeeping motion (six degree-of-freedom)
