Location Factor (Excl.Submarine Cables)

Description

This function calculates the location factor for submarine cables based in the specific location of the cable. See section 6.5 on page 44 in CNAIM (2017). For calculating the location factor for all other network assets please see the function location_factor().

Usage

location_factor_sub(
  topography = "Default",
  sitution = "Default",
  wind_wave = "Default",
  intensity = "Default",
  landlocked = "no"
)

Arguments

topography

String. Describe the topography around the submarine cable. Options: typography = c("Low Detrimental Topography", "Medium Detrimental Topography", "High Detrimental Topography", "Very High Detrimental Topography","Default" )

sitution

String. Descibes how the submarine cable af fixed to the sea floor. Options: sitution=c("Laid on bed", "Covered", "Buried", "Default")

wind_wave

Numeric. Options: wind_wave=c(1, 2, 3, "Default"). Settings:

  • wind_wave = 1: Sheltered sea loch, Wind <200 W/m2

  • wind_wave = 2: Wave <15kW/m, Wind 200-800 W/m2

  • wind_wave = 3: Wave <15kW/m, Wind 200-800 W/m2

  • wind_wave = "Default": No data available

intensity

String. Combined wave and current energy factor. Options: intensity=c("Low", "Moderate", "High", "Default").

landlocked

String. Options: landlocked = c("yes","no"). Default setting for landlocked = "no".

Value

Numeric. Location factor
