Business case to refit a Tanker to use Onshore Power Supply (OPS)

This case study explores the retrofit of the crude oil shuttle tanker Toril Knutsen to use onshore power supply (OPS) during port stays. The analysis assesses onboard retrofit requirements, power demand at berth, CAPEX, and the resulting business case. Total CAPEX is estimated at around $4M for a conservative tanker-specific configuration. Payback can fall in the range of 1 to 4 years, with most value driven by reduced FuelEU, EU ETS, and IMO-related compliance costs.
