The Art of Dredging

Dredging and shipping

Tropical cyclones

In 2003 I witnessed my first typhoon, in Jing Hae typhoon shelter area in Korea.

Jing Hae is a huge body of water, surrounded by hills, with a small entrance, at the south coast of Korea.

We were not the only vessel in that shelter area. In a matter of 24 hours, the area filled with ships and was densely packed, all lying at anchor within 2 - 3 cables from each other. Some were unproperly ballasted, others did not keep their engines on standby or running. It was Russian roulette in there.

As it happened: two ships collided in front of us, a Panamax hit a large fishing trawler, the trawler sunk in a few minutes time, leaving 15 crewmembers in the water, in the midst of this typhoon. 

After a fierce struggle, crew of Gerardus Mercator could rescue 5 man from the water, battling wind forces well above 12 Beaufort during three hours. 

(Eventually all the crew of the sunken vessel was saved.)

                                                    The morning after 

In 2004 JDN lost a dredger "Cristoforo Colombo" in an extratropical-cyclone on Sachalin Island, and in 2006 MV Pompei was completely disabled by yet another typhoon in South China Sea.

By 2007 I was truly obsessed with the subject, not at least because I live in the Philippines, a typhoon-infested archipelago. I learned from first-hand experience that tropical cyclones do not read textbooks, and don't play by the book. They are rogue.

I wrote "Tropical Cyclones, a briefing for mariners", starting from my own 8 years of working amidst typhoons in and around South China Sea.
