Philippine-flagged cargo vessel Andrea Princess 2 caught fire while at anchor off Cebu, the Philippines, on April 22.
The fire was contained by two Philippine Coast Guard vessels while the 20 crew aboard were rescued.
No evidence of a possible oil spill was found by the Coast Guard Marine Environmental protection team.
A preliminary investigation into the incident revealed that the crew were conducting welding on the hydraulic hatch of the vessel’s cargo hold on its forward portion, where a pile of wood and paint was stored.
The 615 dwt vessel was loaded with 8,570 liters of fuel oil and 100 liters of lube oil when the fire broke out.
