The orderbook for the largest oil tankers is growing larger, Gibson Shipbrokers warns. But the bright spot is that smaller tankers are seeing ever smaller orderbooks.

Gibson noted that the current VLCC orderbook, which saw an additional two ships being ordered at DSME by Guggenheim Capital, currently stands at 16% of the total fleet. The brokerage noted the "risk of over-ordering if investment in VLCCS continues at such a relentless pace."
