Molikpaq blast densification project sakhalin island, russia

摘要

This paper is a summary of the work carried out by an international team of speciallists in the successful explosive compaction of the sand fill core of the Molkpaq offshore oil production structure. The sand fill core is an essential element for the stability of the structure. The sand core must resist liquefaction forces caused by heavy wave action, ice loading, and earthquakes. Explosive compaction methods were used to improve the stability of 220,000 cubic meters of coarse dredged sand placed in the core area.
