Underwater Blasting Operations in the Proximity of Existing Structures: an Approach to Safety Assessment
The construction of new subsea installations and systems nearby existing structures (such as pipelines) may require blasting operations for obstacle removals, seabed preparation, removal of large boulders, etc. The paper presents an approach for the definition of possible effects on existing subsea...
