... Abstract Predictive equations of normalized shear modulus (G/G max ) and material damping ratio (D) are presented for calcareous sand, siliceous carbonate sand and carbonate sand of the Bay of Campeche and Tabasco Coastline. This was achieved using a database of 84 resonant column tests and 252...

... consisted of seabed excavation to remove the in-situ carbonate sand and reef limestone, and replacement with the engineered rock fill to form a sufficiently level surface for placement of each of the four pad footings. Installation of the DCP at the Malampaya site commenced after a 3 day wet-tow from...

While considerable investigation of the anchor line performance in clay has been conducted, there has been limited investigation into the anchor line behavior in sand, and none in carbonate sand. The limited relevant information in the codes...
