This is a question for pipeline enginers in offshore field.
Is there any guideline or reference code which tells the frequency of pigging a pipeline used(for transportation of well fluid/crude oil) for descaling purpose.
What is international practice followed by operators to pig the pipelines connected with SPM calm buoys.

RE: This is a question for pipeline eng
As for, operational and descaling pigging, the frequency depends on the commodity. The initial pigging runs provides information on the scale build up, depending on which a regular interval can be determinded.
As an example, Sarawak Shell Malaysia performs [IBC conference notes]:
12, 16 & 18 inch Belingian oil : 1 in 3 months.
8 , 12 & 18 inch Samarang oil : 1 in 2 weeks.
30, 32 & 36 inch Laconia oil : 1 in 6 months.
