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 a given position of an obstacle drifting relative to the target marine structure;
modeling with the computer system at least two different tow routes actively diverting the same obstacle over time from the given position to at least two different tow positions relative to the target marine structure by using at least two different tow models for calculating an active diversion of the same obstacle in each of the at least two different tow routes;
modelling with the computer system one or more altered drift tracks of the obstacle for each of the active diversions by using one or more drift models for calculating a passive drift of the obstacle over time form the at least two different tow positions of each of the active diversions;
presenting with the computer system the at least two different tow routes and the one or more altered drift tracks for each of the active diversions for comparison to one another; and
initiating with the computer system based on the comparison a tow operation to actively divert the obstacle.

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.
