pof_future_submarine_cables_10kv_pex: Future Probability of Failure for 10kV Non Pressurised submarine cables

Description

This function calculates the future annual probability of failure per kilometer for a 10kV non pressurised submarine cables The function is a cubic curve that is based on the first three terms of the Taylor series for an exponential function.

Value

DataFrame. Future probability of failure along with future health score

Arguments

utilisation_pct

Numeric. The max percentage of utilisation under normal operating conditions.

operating_voltage_pct

Numeric. The ratio in percent of operating/design voltage.

topography

String Topography

sitution

String Situation

wind_wave

String Wind Wave

intensity

String Intensity

landlocked

String Land Locked

sheath_test

String. Only applied for non pressurised cables. Indicating the state of the sheath. Options: sheath_test = c("Pass", "Failed Minor", "Failed Major", "Default").

partial_discharge

String. Only applied for non pressurised cables. Indicating the level of partial discharge. Options: partial_discharge = c("Low", "Medium", "High", "Default").

fault_hist

Numeric. Only applied for non pressurised cables. The calculated fault rate for the cable in the period per kilometer. A setting of "No historic faults recorded" indicates no fault.

condition_armour

String Condition Armour

age

Numeric. The current age in years of the cable.

reliability_factor

Numeric. reliability_factor shall have a value between 0.6 and 1.5. A setting of "Default" sets the reliability_factor to 1. See section 6.14 on page 73 in CNAIM (2021).

k_value

Numeric. k_value = 0.0658 by default.

c_value

Numeric. c_value = 1.087 by default. The default value is accordingly to the CNAIM standard see page 110

normal_expected_life

Numeric. normal_expected_life = 80 by default.

simulation_end_year

Numeric. The last year of simulating probability of failure. Default is 100.
