Abstract
Systems and methods are disclosed for deploying one or more anchor piles on the seafloor using submersible line tensioning systems and techniques to achieve tensioning of mooring lines at the seafloor rather than at the conventional vessel deck level. Among other things, the disclosed systems and methods may be advantageously employed for tensioning mooring lines for Mobile Offshore Drilling Units (MODUs) when additional mooring legs must be added to the original complement of MODU legs, as well as and for tensioning mooring lines for vessels having turret mooring systems, each of which have limited space for surface tensioning equipment.
