The Kamsarmax Bulk Carrier "MASTER" (GT 44,619 - DWT 81,588), fully laden with soya beans, en route from Kalama Port, Portland, USA, to Jingtang, China, began running out of fuel due to bad weather (head winds/seas) during her westerly transpacific crossing.

On 5 February, Tsavliris despatched the S/T "Koyo Maru" (GT 2,474 - BHP 10,000) from E of Cape Ryori Saki, Japan, to the vessel's assistance. On 7 February, the tug met up with the vessel and commenced escorting her towards Muroran, Japan.
On 8 February, the vessel ran out of fuel, whereupon the tug connected up for towage to destination. On 9 February, the convoy arrived at Muroran anchorage for the vessel to replenish bunkers and the operation was successfully completed.
