Last here in 2011, CSL Spirit has been operating as a shuttle bulker to load iron ore onto larger bulkers for export. As large bulkers are 2 large to tie up at the pier, CSL Spirit is loaded, then offloads into the larger vessel anchored off shore.
Several trips are required to fill one vessel.
I expect once she is done bunkering, she will sail back to Sept-Ills. CSL Spirit also severed national gypsum on numerous occasions.
