Terrifying Simulation Reveals How A Man Survived 60 Hours Trapped Underwater After Boat Sank

In a truly miraculous tale of survival, a man managed to stay alive for two and a half days, trapped underwater in nothing but his boxers. He found himself in this life-or-death situation after waking up to use the toilet, only to face an unimaginable ordeal.

It has now been 11 years since Harrison Okene defied all odds when his boat capsized about 20 miles off the coast of Nigeria. The surging water forced him into what turned out to be the only room on the vessel with a pocket of air, saving his life.

A chilling simulation has recently been created by the YouTube channel Brew. It shows, step-by-step, how the then-29-year-old managed to survive for an unbelievable 60 hours at the seabed of the Gulf of Guinea, a region in the Atlantic Ocean.

At the time of the incident, Harrison was working as a cook on the Jascon-4, a tugboat that had a crew of 12 others. The boat was tasked with stabilizing an oil tanker when disaster struck.

One night, a massive wave hit the tugboat, flipping it upside down along with the crew inside. Harrison, who was in the bathroom wearing only his boxers when the wave hit, was gripped by panic as water started pouring into the small cubicle around him.

Managing to push the bathroom door open, Harrison stepped into total darkness. He noticed the boat’s propellers were pointing up while the wheelhouse was facing down—a clear sign of the vessel's catastrophic position.

In the chaos, he encountered a few of his colleagues. Together, they struggled to open the boat’s hatch while the rising water levels made their efforts increasingly difficult.

The powerful force of the water eventually swept Harrison away from the exit and pushed him further into the vessel. He ended up in another bathroom, this one attached to the second engineer's cabin.

At first, Harrison believed this turn of events had sealed his fate. However, unknown to him, this bathroom had just enough air trapped to keep it from completely flooding, creating a life-saving pocket of air.

He clung tightly to the base of the washbasin, keeping his head in the small air pocket near the ceiling, which, due to the overturned boat, was actually the floor.

At one point, Harrison accidentally broke the door handle of the bathroom. He still believed his best chance at survival was to reach the main exit, not realizing that the boat had already settled on the ocean floor.

Reflecting on his experience, Harrison told the Guardian: "But I told myself, instead of panicking, you have to think of a way out," He added, "The air couldn't go out of the boat completely. Some had to be trapped inside."

To stay above the rising water, Harrison discovered two mattresses. He stacked them on top of each other, creating a makeshift platform that allowed him to remain in the small air pocket of his bathroom sanctuary.

Recalling the terrifying experience, Harrison said: "I tried to kill the fear in front of me," He explained further, "Because one thing that can kill you fast is fear."

"That panic that comes at you, it kills you before your real death comes."

"Because the moment you start panicking, you use too much oxygen."

After nearly 60 hours without food or water and with the air in his chamber running dangerously low, Harrison’s prayers were finally answered. A diving crew, sent to recover bodies from the wreck, unknowingly stumbled upon him.

Harrison noticed strange lights and unusual sounds outside his chamber. Taking a leap of faith, he left his tiny refuge and managed to reach a diver, who then rescued him from his underwater prison.

The incredible rescue was even captured on camera, adding a visual element to his astonishing survival story.

Following his rescue, Harrison was taken from the diver's bell to a recompression chamber. There, he had to spend another three days to avoid the deadly effects of surfacing too quickly after being at such depths.

As he later explained, "Everything was normal. My temperature, blood pressure. I thought, that's not normal,"

Despite the trauma of being the sole survivor of the accident, Harrison faced his fears and, in 2015, became a certified commercial diver, proving his remarkable resilience and determination.

In a heartwarming twist, it was the same diver who discovered Harrison at the bottom of the sea who later presented him with his diving diploma, completing the circle of this extraordinary journey.
