Yes that is true. Technology is available. However, these are all new concepts for the operator. E.g. there is currently no cathodic protection in his plant. He has no pipeline near the water table. It would take a bit of selling. Over the road the next plant has an underwater pipeline. But this...
@metengr: It is casing - oil country tubular goods, not casting. I am not sure whether you understood casting or not.
@SJones: The corrosion is inside the annulus. Outer casing is 20" K55. Inner casing (the corroded one which needs to be repaired) is 13 3/8" K55. The corrosion at the top is...

Directional drilling does not look so attractive in this case after all. There is already a lot of underground infrastructure there and they would have to go down to 9 ft plus. Its being a marine terminal, that would be approx. the level of the salt water table. The problems due to routing a...
Sorry that I give the info only piece meal. The planning is to route the line per piperack along the dike (inside the dike) of the diesel tanks. Pipe line will be at the level of the dike wall top. Pipe trench/draining trench (pipes with other products) will run underneath this rack (vertical...
Thanks for all your input. Actually my original question was prompted by a misunderstanding between myself and the plant HSE manager. With "tankfarm" I understood the complex (bunds, unclassified areas, everything). With "tankfarm" he meant the actual tanks impoundment within the bund walls...
Does anybody know whether there is a ruling, legislation, guideline or similar (in any country) which prohibits or strongly recommends against the routing of an LPG transfer line through an oil products tank farm? The situation I am thinking of is an existing marine terminal. LPG would be...
