Comparative Ice Drift and Tow Model Analysis for Target Marine Structure
First Claim
1. A marine threat modelling method for a target marine structure conducting a set operation in a body of water, the method comprising:
- monitoring with a computer system at least one given position of at least one obstacle drifting in a vicinity of the target marine structure as the target marine structure conducts the set operation in the body of water;
modeling with the computer system at least two subsequent positions of the at least one obstacle over time from the at least one given position relative to the target marine structure by using at least two models for calculating movement of the at least one obstacle; and
presenting with the computer system the at least two subsequent positions for comparison to one another.

Abstract
A marine threat monitoring and defense system and method protects a target vessel in icy or other marine regions. The system uses communications, user interfaces, and data sources to identify marine obstacles (e.g., icebergs, ice floes, pack ice, etc.) near a target vessel performing set operations (e.g., a stationed structure performing drilling or production operations or a seismic survey vessel performing exploration operations with a planned route). The system monitors positions of these identified marine obstacles over time relative to the target vessel and predicts any potential threats. When a threat is predicted, the system plans deployment of support vessels, beacons, and the like to respond to the threat. For example, the system can direct a support vessel to divert the path or break up ice threatening the target vessel.
