Carmacoring and D’Appolonia provide an innovative large diameter piston coring system for use in offshore geotechnical and geophysical surveys. The main advantages of the system are 1) easy installation and deployment from a wide range of vessels, 2) excellent recovery of high quality samples using an active piston, 3) variable barrel length (3 to 30 m) 4) no water depth limitations and 5) cores can be used for both geotechnical and geohazard assessment. The system can be deployed to collect long piston cores during conventional geophysical surveys, allowing considerable schedule savings for offshore projects. This poster discussed the main attributes of the system: characteristics of the Carma Piston Corer system, the track record of the tool in terms of sample recovery and water depths, Angel Descent deployment for reduced disturbance, geotechnical sample quality, and examples of application to both geotechnical and geohazard projects.
