A Ship Collision Risk Analysis is used to assess the risk of collisions between a ship and an offshore installation.  The overall risk posed to an offshore installation due to a ship collision is a function of the likelihood of a ship colliding with the installation and the impact energy transferred during the collision.

The risk analysis involves the following steps:

• Identification of marine traffic, which could impact on the installation.
• Determination of collision frequencies from historical data.
• Estimation of the probability of marine traffic impacting critical platform structures.
• Determination of the consequences of ship collisions on critical structures by estimating the energy transferred from a collision event.
