Seawater/Hydrocarbons/Carbon Steel

I propose to pump crude oil and seawater in a carbon steel pipeline. I propose to treat the seawater to control corrosion as follows:

1) Considering hydrazine oxygen scavenger to remove oxygen mechanism of corrosion.

2) Considering biocide (or similar) to reduce anaerobic organic growth and anaerobic corrosion.

What other considerations should I be reviewing?

Thank you.

You should also consider the use of filming corrosion inhibitors and regular pigging. You can also model the corrosiveness of the pipeline based on flow velocity and line geomitry, a company to consider for this is CorrosionWatch based in Calgary Alta. Canada. Contact JamesFerguson@CorrosionWATCH.com.
They should be able to help you out.
