4.3 Calculation of oil outflow parameters

 The oil outflow parameters P O, OM and OE should be calculated as follows:

  Probability of zero oil outflow, P O:

where:
i = represents each compartment or group of compartments under consideration, running from i = 1 to i = n
Pi = accounts for the probability that only the compartment or group of compartments under consideration are breached
Ki = equals 0 if there is oil outflow from any of the breached cargo spaces in i. If there is no outflow, Ki equals 1.

  Mean oil outflow parameter, OM:

where:
Oi = combined oil outflow (m3) from all cargo spaces breached in i
C = total cargo oil capacity at 98% tank filling (m3)

  Extreme oil outflow parameter, OE:

 where the index “ie” represents the extreme outflow cases, which are the damage cases falling within the cumulative probability range between 0.9 and 1.0 after they have been arranged as specified in paragraph 6.1.
