Submarine pipelines are commonly used along coastlines for wastewater draining or for gas/fluid transportation from platforms at deep waters. Depending on the installation area, they are subject to waves and currents and the common solution to improve the pipe stability is to cover them with bitumen or articulated concrete block mattresses. The aim of the present study is to investigate the wave-induced forces on the articulated concrete block mattress covering a submarine pipe, laid on sea bed, by using a RANS numerical model in order to evaluate its global stability.

Abstract

Submarine pipelines are commonly used along coastlines for wastewater draining or for gas/fluid transportation from platforms at deep waters. Depending on the installation area, they are subject to waves and currents and the common solution to improve the pipe stability is to cover them with bitumen or articulated concrete block mattresses. The aim of the present study is to investigate the wave-induced forces on the articulated concrete block mattress covering a submarine pipe, laid on sea bed, by using a RANS numerical model in order to evaluate its global stability.
