Divers in sea-hunt for drop site of reef balls in Bintulu

KUCHING: When Malaysia LNG Group of Companies and the Sarawak Forestry Corporation (SFC) teamed up to save the marine ecosystem in Bintulu, they needed divers to send ahead and evaluate the drop site.

Fortunately, they had to look no further than within their own ranks for both divers and an experienced dive instructor.

Helming the dive team for BEACON (Biodiversity, Environment and Conservation) is Christopher Cri, 54, an SFC enforcement officer who also happens to be an instructor with National Association of Underwater Instructors (NAUI).

With over 20 years of diving experience, Chris is proud to be onboard this pioneer project, lending his skills to keep his team safe and do what they go underwater to do – make sure the sea bed in a certain location can take a cluster of reef balls.

The reef balls used for this project weighs about 2 tonnes each and has an expected lifespan of 500 years. It is made of a special material that mimics natural limestone.

It is non-organic and non-toxic, but has rough surfaces suitable for settlement of coral polyps and other micro organisms. The hollow centre offers shelter for marine life such as turtles. The sharp outside edges is also a deterrent for destructive trawlers nets.

The benefits it will bring to marine life in the area is great, but first, the BEACON divers must make sure the reef ball does not sink into the silt and disappear.

Chris explained that what they look for at the sea bed is ‘stability’.

“You can measure it with a stick. You dig a certain depth and then feel for stability. If you can feel the hard clay soil under the silt, then the sea bed is stable.”

In the sunny June days before the deployment of the first 200 reef balls, the waters off Similajau National Park was found to be unsuitable. The sea bed was muddy and visibility was almost nil. The team spent three days straight diving.

Wahid Kep, said that with zero visibility, it was a very good thing that neither he nor any other diver in the team succumbed to claustrophobia.

“It was quite an experience. There are a lot of species down there, and I’m looking forward to more dives,” he said.

Wahid, a MLNG fire marshal, recently received his scuba certification from PADI (Professional Association of Diving Instructors), having trained specially for BEACON.

“I have been diving ‘kampung-style’ since I was young,” he said. The village rivers and streams were enough to satisfy a boy, but Wahid always dreamt bigger.
