(I'm not sure if the self-unloader conversion was due to a cargo contract or not - perhaps William Lafferty will know).
I was going to respond to this yesterday, but was too lazy to do so. Now I feel compelled to respond :-) You're absolutely right about the reason for the exchange of vessels. The conversion coincided with Jones & Laughlin signing a twenty year float contract with Interlake. The conversion was announced in November 1965 to be carried out by American Ship Building Company's Toledo plant for completion in July 1966 and would yield a very efficient vessel with an unloading speed of 5000 tons per hour. The rise of taconite motivated the conversion coupled with the J & L contract. Interlake was then in an expansion program, especially the movement of Labrador ore, so it makes sense that a vessel adaptable to various cargoes, including taconite from Minnesota, and with a rapid unloading speed to offset the diminishment of carrying capacity would be attractive to Interlake. Indeed, John Sherwin stated in early 1966 that taconite would reverse the trend of ore coming from Canada, stating "[t]he demand for taconite pellets has now reversed this process, ... the company has arranged to acquire another vessel in the 600-foot class from another fleet," this I'm certain a reference to the
Purnell, which entered service as a self-unloader 15 August 1966. The decision to sell the vessel to Oglebay Norton in January 1970 was, in the words of Interlake, "to concentrate on straight deckers in the bulk trades," while O-N stated the purchase "... was in keeping with our long range program to facilitate more efficient movement of cargo for customers."
