Oil bunkering vessel explodes after loading crude oil off the coast of Bonny.
Four crew members were said to have been killed in the fire.

Thank God.

Crude oil spills from sabotaged pipelines, polluting land and water.

Workers are sent to investigate and determine the cause and points of leakage.

leak points are discovered.
In this pix, two valves are located close together.

Connect a hose from valve to vessel, open valve and within hours you have a full vessel loaded with thousands of barrels of crude oil worth millions of dollars.

Now, company sends pipeline repair and maintenance team.

In most cases, workers are sent to a house boat.

Workers arrive house boat.

There's usually lots to eat.

Workers leave for site very early in the morning.

On board the barge, gathering equipments and tools for work.

In some cases, a coffer dam may be built. This protects against collapse of bond wall in very slurry terrain.

Cutting off the valve from the pipeline, in readiness for clamping.

Six inches valve successfully removed from pipeline.
This operation helps save millions (probably billions) of dollars worth of crude oil lost to the activities of illegal bunkering in Nigeria.

Kudos to the pipeline maintenance crew.

The End..
