System for converting existing tankers to shuttle tankers

Abstract

A system for converting Jones Act/OPA90 compliant tankers to shuttle tankers includes a dynamic positioning system, means for bow loading of crude oil, and the necessary power systems to make each operational.

What is claimed is:  
     
         1 . A kit for converting a Jones Act compliant, OPA90 compliant tanker into a shuttle tanker for use with a floating storage and offloading vessel, said kit comprising: 
 a dynamic positioning system for: 
 ascertaining the position of the tanker and then determining the movement required from said ascertained position to a predetermined position;  
 means for moving said tanker from said ascertained position to said predetermined position;  
   means for loading fluids from said floating and storage and offloading system to said tanker, said system for loading fluids constructed and arranged to be located at the bow portion of the tanker;    power means for driving said means for moving said tanker and said means for loading fluids.    
     
     
         2 . The kit as defined in  claim 1  wherein said tanker further includes at least one thruster mounted to the hull of the tanker.  
     
     
         3 . A method for converting a Jones Act compliant, OPA90 compliant tanker into a shuttle tanker for use with a floating storage and offloading vessel, said method comprising the steps of: 
 adding a plurality of thrusters at various locations around the hull of the shuttle tanker;    controlling said plurality of thrusters and the main propulsion and rudder system of the shuttle tanker to maintain the shuttle tanker in a predetermined position;    adding a bow loading system to the front of the shuttle tanker.
