A Conceptual Study of the Factors Involved in Installation, Operation, and Recovery of Moors with Attached Bottom-Mounted Sensors.
Abstract
A conceptual study is reported of potential failure mechanisms associated with installation, operation and recovery of deep-sea buoy moors with attached bottom-mounted sensors. The study is directed to the 'anchor-last' mode of installation. The effects considered include, among others, initial launch geometry, stability characteristics of the components (including torsional characteristics of the cables, both internally and externally generated), relation of the outlying instrument leads to the mooring riser, spin-stability of objects suspended by multiple lines and hydrodynamic effects such as strum and component rotation. The length of the instrument leads in relation to the depth is identified as an important parameter. The utility of modeling and the status of algorithms useful in the design of deep-sea mooring installations are discussed. A general installation procedure is suggested.
