Algerian state shipowner ENTMV has extended a scrubber tender for two of its ships.
It wants closed-loop systems provided and installed on the 1,300-passenger car ferries Tassili II (built 2004) and El Djazair II (built 2005).
The tender deadline has been stretched from 19 November to 30 December.
Offers will be binding for three months.
ENTMV is listed with two other vessels.
