What Counts as "Supply" I

Image result for OSV

I wrote something recently for one of my content customers about the economics of offshore support vessels (OSVs). These are the specialized ships that provide a range of support services to offshore oil and gas drill platforms.

The bottom line is that OSVs are a lousy investment idea. If given an opportunity to invest in such a vessel or in any corporate entity whose main line of business involves owning or operation such vessels: run the other way!

There are too many of these darned things and (though I wasn't allowed to put it this bluntly for the
commercial cite I was writing for), the oil majors take advantage of the fact that there are so many
of them. They pocket the savings.

Understanding the oversupply problem requires taking into consideration both cold stacked and
warm stacked OSVs. To review: a warm stacked vessel is left at port, but continues in operating
condition. It can readily be reactivated. Indeed, a warm stacked vessel continues to have a
working crew. As some people like to say, the term “warm” can refer to the crew beds.


A cold stacked vessel, on the other hand, is one where the crew’s beds, as well as the engines
and kitchens, go cold. If a vessel is cold stacked not because of its age or infirmities but for
market reasons, and without any expectation of a scrapyard to come, then the engine must be
filled with protective fluid, and the vessel as a whole protected from the elements. A cold stacked
vessel protected in this way can be reactivated, but that entails costs between $1.5 and $2.5 million.


Further, the longer a stacked vessel stays idle, the less likely it is ever to make a return to the market.

Thus: it is tricky to do a economics textbook’s supply-and-demand discussion of the vessels available in relation to the demand for the services they provide, because the percentage of the cold stacked vessels that are truly still available to service demand is itself a judgment call. What is certain is that there exists considerable oversupply and that the law of supply and demand applies not just to the value of the vessels but to the value of the services they provide. Right now, there is a buyers’ market for the chartering of OSVs.

This is not offered merely as a random bit of business news. I'll have something to say tomorrow about the idea of "supply" in economics, drawing on this matter.

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.   We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a maj...

Searle: The Chinese Room

John Searle has become the object of accusations of improper conduct. These accusations even have some people in the world of academic philosophy saying that instructors in that world should try to avoid teaching Searle's views. That is an odd contention, and has given rise to heated exchanges in certain corners of the blogosphere.  At Leiter Reports, I encountered a comment from someone describing himself as "grad student drop out." GSDO said: " This is a side question (and not at all an attempt to answer the question BL posed): How important is John Searle's work? Are people still working on speech act theory or is that just another dead end in the history of 20th century philosophy? My impression is that his reputation is somewhat inflated from all of his speaking engagements and NYRoB reviews. The Chinese room argument is a classic, but is there much more to his work than that?" I took it upon myself to answer that on LR. But here I'll tak...

Recent Controversies Involving Nassim Taleb, Part I

I've written about Nassim Taleb on earlier occasions in this blog. I'll let you do the search yourself, dear reader, for the full background. The short answer to the question "who is Taleb?" is this: he is a 57 year old man born in Lebanon, educated in France, who has been both a hedge fund manager and a derivatives trader. He retired from active participation from the financial world sometime between 2004 and 2006, and has been a full-time writer and provocateur ever since. Taleb's writings for the general public began where one might expect -- in the field where he had made his money -- and he explained certain financial issues to a broad audiences in a very dramatic non-technical way. Since then, he has widened has fields of study, writing about just about everything, applying the intellectual tools he honed in that earlier work. As you might have gather from the above, I respect Taleb, though I have sometimes been critical of him when my own writing ab...
