AI Technical Summary

Benefits of technology

[0008]Thus, the embodiments of present invention comprise a combination of features and advantages that enable substantial enhancement of mooring a floating vessel. These and various other characteristics and advantages of the present invention will be readily apparent to those skilled in the art upon reading the following detailed description of the preferred embodiments of the invention and by referring to the accompanying drawings.

Problems solved by technology

Moving the pull-in winches increases the time needed for mooring as well as increases the difficulty in making later adjustments of the mooring system, such as relocating the vessel within its watch circle.
This process can be time consuming when the mooring lines can only be adjusted one line at a time.

Embodiment Construction

[0007]Embodiments of the present invention include a mooring method for a moored vessel that comprises a first chain stopper that is fixed to the vessel and is operable to selectively couple an upper chain to the vessel. A chain tensioner is coupled to the vessel and is operable to pull the upper chain. A second chain stopper is fixed to the vessel and is operable to selectively couple the upper chain to the vessel. The chain tensioner engages the upper chain at a location between the first chain stopper and the second chain stopper.

Abstract

A mooring method for a moored vessel that comprises a first chain stopper that is fixed to the vessel and is operable to selectively couple an upper chain to the vessel. A chain tensioner is coupled to the vessel and is operable to pull the upper chain. A second chain stopper is fixed to the vessel and is operable to selectively couple the upper chain to the vessel. The chain tensioner engages the upper chain at a location between the first chain stopper and the second chain stopper.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]Embodiments of the present invention relate to methods and apparatus for mooring floating platforms. More specifically, certain embodiments of the present invention relate to systems for tensioning mooring lines that are connected to a floating vessel.[0004]Multi-leg mooring systems generally include a plurality of mooring lines extending outward from a floating platform to a plurality of anchors set into the seafloor. Each mooring line comprises a short length of chain extending from the vessel and connected to a long length of mooring line running to the anchor. Common procedures for anchoring the vessel include extending (pay out) the chain segment from the vessel so as to connect the chain segment to the mooring line that is connected to the anchor, which has been previously set at the seafloor. The chain...
