Apparently was laid up in Abidjan Anchorage 3/2013, and AIS signals stopped six months later

Looks like it was a fire onboard. Does somebody know how it happened?

Next to her is the AHTS vessel GULF FLEET NO 102 (IMO 8127464). She was built by Hudson Shipbuilders in Pascagoula MS in 1982, originally for Gulf Fleet Supply Ships. That company later became part of Tidewater Marine. She was put under Vanuatu flag about 2003, and later sold to TCO Marine Ltd of Port Harcourt, Nigeria. She's currently classes as "laid up, class suspended."
