Time-Varying Risk Measurement for Ship Collision Prevention

Risk assessment of ship/platform collision

Although there have been few collisions between ships and offshore installations, the grave consequences of such a collision has provoked the study of the probability of collision worldwide. A theoretical study is undertaken on the assessment of risk of collision in this paper. The causes of collision and the models of evaluating the risk collision are reviewed, which are then followed by some ...

A Survey on Ship Collision Risk Evaluation

Recently, ship collision avoidance has become essential due to the emergence of special vessels like chemical tankers and VLCCs (very large crude carriers), etc. The information needed for safe navigation is obtained by combining electrical equipment with real-time visual information. However, misjudgements and human errors are the major cause of ship collisions according to research data. The ...

Ship collision risk assessment for the Singapore Strait.

The Singapore Strait is considered as the bottleneck and chokepoint of the shipping routes connecting the Indian and the Pacific Ocean. Therefore, the ship collision risk assessment is of significant importance for ships passing through the narrow, shallow, and busy waterway. In this paper, three ship collision risk indices are initially proposed to quantitatively assess the ship collision risk...

Probabilistic Method for Predicting Ship Collision Damage

Time-varying risk premia

Time-varying risk premia (TVRP) is one of the four sources of stock return autocorrelation. TVRP arises in a securities market equilibriumwhen the equilibrium expected returns of the available investments vary over time; in particular, the presence of TVRP does not indicate pricing inefficiency. This paper provides equilibrium upper bounds on TVRP, as a function of the return period, the time h...
