  • Page 66 TRIAXYS™ Directional Wave Buoy User Manual version 13 Figure 18: Standard 20 to 150 m TRIAXYS Mooring Configuration There are several mooring designs that can be used to deploy the buoy in deeper water or faster currents. These include false-bottom moorings and inverse catenary moorings. There are many references in oceanographic literature documenting alternative mooring strategies as well as commercial mooring design programs available.

  • Page 67: Deployment Procedures

    There are no extraordinary procedures that need to be followed to prevent damage to any of the payload components or sensors. The TRIAXYS™ Buoy is a rugged instrument designed to take minor bumps anticipated through the course of routine field operations. There are no limitations associated with spinning or freezing.

  • Page 68: Software And Data Formats

    The wave processing algorithms reside both in the buoy firmware and WaveViewT base station software for VHF and GSM transmitted data. The TRIAXYS™ Post Processing Software will take raw logged TRIAXYS™ Buoy data and perform all wave analysis and archive the data into various data products.

  • Page 69: Motion Analysis

    4.1.5. Low Frequency Energy The Root Mean Square (RMS) noise value for the accelerometers in the TRIAXYS™ sensor is about 0.0005g. This noise is uniformly distributed over the nominal measurement bandwidth of 1 Hz so the vertical acceleration spectra have a fairly constant amplitude of approximately 0.0000 1 (m2/s4)/Hz at all frequencies.

  • Page 70: Directional Wave Analysis

    4.2. TRIAXYS™ Data Formats The data is transmitted from the TRIAXYS™ Directional Wave Buoy as per the set-up instructions of the Buoy User Manual via either VHF, GSM cell phone telemetry and email receipt of YYYYMMDD.RX data. The WaveViewTM software builds complete data files from the repeated messages. It does not archive redundant data.

  • Page 71: File Yyyymmdd.rx

    NOTE: In areas where there is significant radio interference, the operator may see many extra data sets of random Hex values with a header time stamp. A valid TRIAXYS™ message should begin with "7F". The timing of the incoming data time stamps should correspond to the set-up parameters on the buoy, i.e., reception hourly at 27 minutes past the hour for a 25 minute sample starting at the top of the hour.

    How is the TRIAXYS™ Buoy constructed? A: The TRIAXYS™ hull consists of two parts. The lower half or hull is constructed of a single piece of 316 stainless steel covered with a thermal powder coat finish and the dome is constructed of clear polycarbonate.
  • Page 106 How is a TRIAXYS™ Buoy deployed? A: The TRIAXYS™ can be deployed in currents up to about 3kts. Currents greater than this may cause the buoy to submerge periodically. While this will not compromise the buoy in anyway it may affect the quality of the data and the reliability of the telemetry.
  • Page 107 Please refer to the User's Manual for instructions on removal and replacement of the batteries. The flange gasket between the dome and hull of the TRIAXYS™ should be replaced as required or every two years to ensure its condition is sufficient to allow the dome and hull to form a seal prior to deployment.
  • Page 108 TRIAXYS™ Directional Wave Buoy User Manual version 13 A: As detailed in Section 2.0 of the TRIAXYS™ Manual, the buoy will need to be configured with your operating parameters if you require a set up that is different from the default settings. The PC or Laptop you use for this setup procedure must be equipped with a RAW IR driver and of course a hyperterminal or IR terminal.
  • Page 109 How is Local Magnetic Variation handled on the TRIAXYS™ and on WaveView? A: Local Magnetic Variation is not corrected for on the TRIAXYS™. The wave data sent from the buoy to the base station will not have any corrections for true north applied. In addition, WaveView makes no corrections for local magnetic variation.
  • Page 110 There should be more than enough solar and battery capacity to recharge throughout the spring and summer and be ready again for the next winter.
