To calculate this scenario with the IWRAP tool, do the following steps:
* Define leg;
* define traffic distribution in each direction;
* define causation factors;
* define number of ships in each direction;
* run the job and read results.

Introduction

This page describes one of a series of selected Test Cases which have been analysed/verified by use of the IWRAP program and by hand calculation. Only the number of collision candidates is calculated.

This test case calculates the number of Merging collisions per year.

The Scenario

20090405 Test Case Merging Collision Fig1.jpg


Hand calculation of the Crossing Collision Scenario

Collision due to Merging traffic is calculated in the same manner as calculating Crossing collisions.
