Mean while, we can still find some degrees of risk factors facing the sea transportation, and these risks are mainly casue by  operators error. On this article, we will observe some example, list of ship operators error and other factors which can result to a big disaster to the ship operation.
As recorded, about 75-96% of marine accidents are caused by human errors and they occurs in these categories of operations and forms ;

• 84-88% mostly tanker accidents
• 79%  towing vessel grounding
• 89-96%  collisions
• 75%  Allison's
•75% fires and explosions

Ship Collision
When we talk about human errors, what do we mean?  Human error are mostly described as being one of the followings:

That collision was an example of human error. According the witness "The cause of the casualty was that the commanding officer of the USCGC CUYAHOGA failed to properly identify the navigation lights displayed by the M/V SANTA CRUZ II. As a result he did not comprehend that the vessels were in a meeting situation and altered the CUYAHOGA's course to port taking his vessel into the path of the SANTA CRUZ II."
