DEVICE AND METHOD FOR ESTIMATION OF SEA BOTTOM STATE AT AREA OF EMBEDDING ANCHOR Russian patent published in 2001 - IPC

FIELD: devices for measurement of parameters of anchor embedding in sea bottom and additional measurement of such parameter as resistance of ground to embedding. SUBSTANCE: device monitors embedding of anchor at separate areas of bottom keeping record on embedding procedure and indicating nature of ground in stratum of embedding area. Device performs measurements through point on anchor as anchor moves over embedding trajectory. Device includes units located in hull where anchor is carried for measurement of distance between two points lying on trajectory as well as measurement by means of additional units at separate moment, thus making it possible to obtain graphical representation of trajectory trace on display. These additional units may contain inclinometer, for example showing inclination of hull at separate moments. Hull may also include penetrometer for measurement of resistance of ground to embedding. EFFECT: possibility of estimation of suitable anchorage for anchors possessing high resistance to horizontal displacement. 23 cl, 7 dwg
