2002, Andrews Survey, EMEC Billia Croo, Seabed Site Investigation series https://portal.medin.org.uk/portal/start.php?tpc=015_ac552a74bde8c0f3e6aa0b6b52f1268f During December, 2002, Andrews Survey carried out 16 marine piezocone penetration tests (PCPT’s) and 16 vibrocores as part of the European Marine Energy Test Centre, Orkney. The fieldwork was performed for RJ McLeod from the vessel ‘Forth Fighter’. The water depth at the test locations was approximately 50m. Penetration of up to 5m for the PCPT’s was specified and achieved. The investigation generally revealed the seabed stratigraphy to be sandy deposits to the north of the site, with glacial till overlying suspected shallow bedrock encountered to the south. 20070731
