Definition of Rank

  • Rank 1 is a one-dimensional parameter
  • Rank 2 is a two-dimensional parameter
  • Rank 0 is a one-dimensional parameter describing the second dimension of a two-dimensional parameter (e.g. bin depths for moored ADCP data)

Data Access Policy

SIMORC data access conditions

The data collated and held at BODC on behalf of the SIMORC project are restricted. However, the data will be available to download from the Official SIMORC Website, as part of the project protocol. The data set will initially include data from the oil companies TOTAL, Shell and BP.


Narrative Documents

Vaisala Analog Barometers Models PTB100 (A), (B) and PTB101 (B), (C)

The PTB 100 series analog barometers are designed both for accurate barometric measurements at room temperature and for general environmental pressure monitoring over a wide temperature range. The long-term stability of the barometer minimizes the need for field adjustment in many applications.

Physical Specifications

Size 97 x 60 x 22 mm
Weight 85g

The barometers use the BAROCAP* silicon capacitive absolute pressure sensor developed by Vaisala for barometric pressure measurements. The BAROCAP* sensor combines the elasticity characteristics and mechanical stability of a single-crystal silicon with the proven capacitive detection principle.

Gill WindObserver II

The WindObserver II is a solid state ultrasonic anemometer, with a stainless steel housing suitable for marine and offshore applications. It measures wind speed and direction over ranges of 0-65 ms-1 and 0-359° respectively. The optional de-icing system is recommended for high altitude and aviation applications.

Range 0-65 ms-1 (0-145 mph) 0-359° -40°C to 70°C
Accuracy ±2% at 12 ms-1 ±2° at 12 ms-1 -
Output rate 1 Hz, 2 Hz, 4 Hz, 5 Hz, 8 Hz, or 10 Hz
Parameters UV, Polar, NMEA, Tunnel
Units ms-1, knots, mph, kph, ft min-1
Averaging Flexible, 1-3600 s

BODC Processing

Data were received by BODC in Excel spreadsheets. These were stabilised into text files and then reformatted to QXF format using BODC transfer function 518. The following table shows how the variables within the files were mapped to the appropriate BODC parameter codes:

Following transfer to QXF, the data were screened using BODC's in-house visualisation software, EDSERPLO.


Project Information

System of Industry Metocean data for the Offshore and Research Communities (SIMORC)

The EU-funded SIMORC project is a collaborative effort between MARIS (Netherlands), BODC (UK), the International Association of Oil and Gas Producers (OGP) and IOC-IODE to provide a harmonised and quality controlled metocean data set from data collected by oil and gas producers, accessible through the SIMORC protocol.
