Soil Temperature for Buried Pipeline Fluid thermal analysis

[Hariharan]

It is well known that buried pipelines get an insulating effect from adjacent soil mass.
Can anyone cite references where the temperature of the soil just below seabed
has been measured and reported? This could also have been used in the analysis
of temperature gradient of the fluid in the pipeline.

Thanks

Hariharan

Hari,
The soil temperature at seabed or just below seabed should be same as the seawater temperature at seabed, what you should probabaly look for is the thermal conductivity of the soil at seabed which in my opinion is dependent on the soil type and porosity.

Try the websites of Logstor etc who makes preinsulated (PUR)pipe for marine applications. They will have data or you can contact them direct.
