MANILA, Philippines — The Philippine Coast Guard (PCG) is eyeing to seal all 24 valves of a sunken motor tanker in Manila Bay on Monday and start siphoning the remaining fuel from the ship on Tuesday, July 30.
Coast Guard Station Bataan Lt. Commander Michael John Encina said the sunken Motor Tanker (MT) Terra Nova has 24 valves. However, 14 valves leaked and these were sealed on Sunday.

“When you say siphoning, it is the process of removing the remaining oil inside the tanker. The tanker has 1.4 million liters of industrial fuel oil (IFO) inside the Terra Nova,” Encina explained in a press conference on Monday afternoon.
“So we need to siphon around 300,000 liters for it to float, according to our expert. The intention is to siphon it, to afloat the vessel, to salvage it, and put it on the shore to prevent further oil spill,” he added.
According to PCG’s earlier statement, the shipping company and the contracted salvor Harbor Star will position and secure the two recovery vessels (barge and motor tanker) on site to commence the siphoning operations on July 30 or July 31.
The contracted salvor said it could siphon “approximately 50,000 to 60,000 liters of IFO daily” and finish within a week. But Encina said the siphoning will last for five to seven days or a maximum of 10 days.
‘Minimal excretion’
Based on PCG’s latest aerial surveillance, the oil spill in Manila Bay has started to lessen.
Encina said the oil spill is at a “minimal scale” of 1 liter per hour or 24 liters per day, which is “very controllable.”
Last July 25, authorities said MT Terra Nova “capsized and eventually submerged” in waters off Bataan province.
On July 27, the PCG said the oil from the sunken motor tanker started to leak into Manila Bay, spreading about 12 to 14 kilometers across the area.
