Applicability of DNVGL-ST-F101 Submarine Pipeline Systems code to landfall pipeline part

[M.A]

What is the limitation of using DNVGL-ST-F101 on the landfall part of the pipeline?

hi

there should be a code break somewhere at the landfall, usually at or close to the pig catcher or valve etc if there is one. F101 should be used right upto the code break. the landfall would probably be a similar location class to a platform riser.

consider pressure testing requirements. might be different across code break, and might be tested separately.

also consider CP systems. onshore is often impressed current. offshore is usually anodes. there can be issues near the code break because of different voltages etc.
