As an interpreter on the Malaysian patrol vessel in 2017
Last week I was working as a translator for about 10 Japanese crews and 25 Malaysian crews including a captain during the workplace training on the Malaysian patrol boat named PEKAN.
This used patrol vessel whose former name was Erimo has been granted to Malaysia from Japanese Government. Before leaving Japan for Pekan, Malysia on March 4th, it underwent a major face-lift, its equipment was renewed and the new crews were trained for 2 weeks.
I wish them Bon Voyage and every success in their new duty.

Prior to the port clearance,  some additional translation work on the operation manuals and the interpretation work on the spot was done by me.

The ship is to be in service for 30 more years.
