Pilotage Paradox

by Paul Drouin

The Cosco Busan accident, as with many others that have the same root cause, can be categorized into what I call the pilotage paradox. For on the one hand, we wish to confide the safety and con of the vessel to the pilot, yet on the other insist it is the crew and captain that are ultimately responsible and accountable for the safe conduct of the vessel.

In the seven minute interval between leaving the inner harbour and striking the bridge pylon, the pilot gave 13 helm orders without the slightest indication on the bridge of the Cosco Busan that anything was amiss. We know this because the National Transportation Safety Board (NTSB) has left an amazing amount of information on their public docket website, including transcripts of the bridge voice recordings.

Leaving berth 56 (Port of Oakland) and passing under the San Francisco-Oakland Bay Bridge is a relatively simple matter, even under blind pilotage conditions, as only two course changes bring you through the span. The Delta-Echo span of the bridge is wide, with a horizontal clearance of 673 meters, and is equipped with a RACON dead center of the span. For the Cosco Busan, winds were light and the vessel would be stemming the flood current as it passed under the bridge. This maneuver should not give an experienced 3rd Mate cause to sweat, much less an experienced pilot.

Under keel clearance was not great for the Cosco Busan, however, and as a consequence hydrodynamic forces on the hull caused by the flood tide would have been strong as the vessel’s sidebody came to obstruct the flow, which was setting at approximately 130° (T) near the bridge and anywhere up to 168° (T) further from the bridge.

Quiz: What city in the world is home to the most billionares? The Answer to this question may suprise you. According to Forbes the honor goes to Moscow.

Pictured above is the Yacht of 41 year old oil tycoon Roman Abramovich. Enlgish Russia tells us:

Roman Abramovich, the Russian Richest Guy (as of 2006), has visited St. Petersburg a few days ago on his “Pelorus” boat, the largest private yacht in the world, with the size of the football field and the price tag of 245,000e or $500,000. He had not come alone, but escorted by two luxury cruise ships carrying other less fortunate Russian

While he is in fact only the 15th richest man and the boat is only the world’s 11th largest, it’s impressive non the less.

The title of one story in this week’s MarEx Newsletter proclaims “Maritime Academy Graduation Heralds the Continuation of Good Times” and nothing affirms this better than a look into the order books of the world’s largest shipyards.

The information the following links comes from the Colton Company: “a small firm of specialized management consultants. Its principal consultant is Tim Colton, an industrial engineer, maritime economist and naval architect, with 49 years of experience in the shipbuilding industry, both in the U.S. and worldwide. Our business is helping your business to grow and to prosper”.

MarineLog tells us:

Tim Colton opens new maritime consultancy
Tim Colton, formerly president of international shipbuilding consultants Colton & Company, has returned to the consultancy biz after three years with Halter Marine. Colton, the perennial moderator of Marine Log’s “Shipbuilding Decisions” conference and a frequent contributor to Marine Log magazine”

Here are the pages of greatest interest:

• Shipyard Activity in 2007. It seems that the Overseas Houston (in Aker’s Philadelphia Shipyard) is the only Unlimited tonnage being built this year.
• Large Cruise Ships on Order. The largest of the large are two more Royal Caribbean’s “Freedom of the Seas” class, the world’s largest (by Gross Tons) cruise ships. They are being built by Aker Turku in Finland and are scheduled to launch in 2009 and 2010.
• Offshore is seeing perhaps the largest growth with 13 Drillships and 39 Semi-Submersibles and 79 Jack-ups on order. View the list here.
• And what is seemingly the Topic of the Day… LNG orders. With an impressive 143 ships ordered we understand the push to build terminals across the U.S.

Of great interest to U.S. Mariners; The U.S. Shipping Fleet. With seemingly every ship under the U.S. flag listed this (along with our own Merchant Fleet Chart) makes for an interesting read. Many thanks to Tim Colton for maintaining this resource. Visit the Colton Company’s Homepage for more valuable statistics.
