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.

Aanderaa Water Level Recorder Model 7
The Water Level Recorder (WLR) model 7 is a self-contained, high precision instrument specifically designed for recording of ocean water levels through precise measurement of hydrostatic pressure. The WLR records pressure, temperature and conductivity (optional) at regular intervals, enabling precise variations in water level to be calculated. The pressure sensor consists of an oscillating quartz crystal which shifts frequency with the force applied to it. Temperature is measured by a Fenwall thermistor.
The data from the WLR7 are stored in a solid-state data storage unit (DSU) which can store up to 65,500 ten bit, PDC-4 coded words in a set of EEPROMS. Click the link for further details on theWLR7.

BODC Processing
Data were received by BODC in MS Excel spreadsheets. They were stabilised into a text format 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:
Original parameter name | Original Units | Description | BODC Parameter Code | BODC Units | Comments |
---|---|---|---|---|---|
Time | DD-MM-YYYY hh:mm:ss | Date and time (Western Standard Time) | AADYAA01 + AAFDZZ01 | Day number and day fraction | Converted to GMT by subtracting 8 hours. |
CurSpd | m/s | Speed | LCSAEL01 | cm/sec | *100 |
CurDirn | degrees True | Direction | LCDAEL01 | degrees True | |
SeaWaterTemp | degrees Celsius | Sea temperature | TEMPPR01 | degrees Celsius |
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.
