How to select pneumatic fender ?

Ship-to-Ship

The fender selection procedure for ship-to-ship operations is outlined below.

Two ship types, sizes and weather conditions such as Calm, Moderate and Rough are initially confirmed.

 

OCIMF Table Selection

Equivalent displacement coefficient ; ''C'' is calculated, and fenders are selected tentatively by using the table in OCIMF Ship-to-Ship Transfer Guide ; '' OCIMF Table Selection''. In this case, initial internal pressure of the fender shall be 50kPa (Pneumatic 50). The selections are designed based on Calm weather condition, therefore if the weather is confirmed as Calm, the fender system can be simply selected from the tables.
