Explosive Charge Applications in Seabed Strengthening for Underwater Pipelines

Abstract The importance and impact of subsoil quality is discussed with regard to the safety and reliability of underwater pipelines. Non-classical operational analysis is employed to define generalised dynamic systems. A model incorporating loading of the subsoil acting on a pipeline immersed in an underwater excavation is a specific case of a generalised dynamic system. This paper justifies the incorporation of the analytical method of generalised dynamic systems into the selected model. An innovative, non-standard and effective method is proposed to compact and improve the subsoil for underwater pipeline foundations using blasting charges.
