Subsea power converters have been identified in recent researches as a
potential means of supplying power to subsea loads and this technology has been
seen as a means to reduce the reliance on offshore platforms. This study
analyses all electric subsea high power system for power generation and
transmission in the offshore oil and gas industry for sustainable subsea
development. In order to accomplish the analysis of power generation and
transmission to subsea loads, the MAT lab SIMULINK software was employed to
ascertain losses arising from the transmission of power to subsea systems. Data
from Agbara and Akpo fields, all located in Nigeria, were analysed using the
MSDC model as an alternative power source for power generation and transmission
to all subsea loads. When the voltage loss between a step out distance at 30 km and
200 km was compared for the Akpo oil field, the plots indicate a significant loss
in voltage. The RMS value of voltage loss increased from 0.8874 at a step out
distance 30 km to 0.9449 for 200 km.
