Suez Canal Authority (SCA) has announced that it will allow ships to burn heavy fuel oil (HFO) when transiting the waterway and will restrict the use of open-loop scrubbers. The restriction on the open-loop scrubbers is consistent with pre-existing restriction on wash water discharges during vessels transit of Suez Canal. The Suez Canal Authority will not put any conditions or restrictions on fuel oil or Open-loop Exhaust Gas Cleaning Systems until ratification of MARPOL Annex VI by Arab Republic of Egypt.
