Online leviathan Amazon has become the latest retailer to try to circumvent the congested containership sector to get goods to market.

Consultancy Alphaliner reported that the US conglomerate loaded a number of its own 53-foot containers on to an open-hatch bulk carrier operated by Gearbulk and Grieg Star joint venture G2 Ocean.

The 50,800-dwt Star Lygra (built 2013) carried the cargo from Shenzhen in China to Houston in the US.

"The ongoing shortage of capacity on many liner trades and continued sky-high container freight rates keep prompting shippers and beneficial cargo owners to look out for alternative options to move cargo across the oceans," Alphaliner said.

G2 Ocean's managing director for the Atlantic, Scott Krantzcke, confirmed 213 newly built 53-foot containers were safely discharged from the Star Lygra at Port Houston, Texas, on 6 October.

One time only?

"This was a one-off project, but due to the ongoing global supply chain challenges, we have carried a greater number of containers this year, and we are expecting this trend to continue well into 2022," he added.

"By doing so, we hope to ease the situation for customers and provide them with the reliability they need," Krantzcke said.

He added that the fleet has unique capabilities that allows the vessels to accommodate the transportation of specialised cargo.

Amazon's move echoes action taken by another US shipper, Walmart, which put its own boxes on three Saga Welco open-hatch carriers earlier this year.

G2 Ocean's L-class ships usually carry cargoes such as forestry product and steel pipes.

They have a notional container capacity of 1,411 teu.

The shipping company has been contacted for comment.

Handy handysizes

Coca-Cola hit the headlines earlier in October, when it revealed it had loaded 60,000 tonnes of material on three handysize bulkers.

Alphaliner said the cargo was concentrate powder shipped in big bags.

This was the equivalent of 2,800 teu of boxes.

The company chartered the 34,400-dwt Aphrodite M, the 35,000-dwt Weco Lucilia C and the 35,130-dwt Zhe Hai 505 (all built 2011), according to a photograph posted on social media.

Bulker association Intercargo said in a statement: "Recent reports that Coca-Cola has chartered three bulk carriers to keep its production lines running serve to highlight the flexibility and efficiency of the dry bulk cargo sector."

The organisation added that the shipping industry has already proven its worth during the Covid-19 pandemic, and now, with the supply chain disruptions during the economic recovery phase, deepsea shipping is adapting to the uneven cargo and container flows.

"Dry bulk carriers are demonstrating the vital role they play at the very heart of the world fleet," Intercargo said.

Mainstream media has been full of news of big cargo owners such as Ikea and Home Depot chartering vessels, but brokers point out that what this really means is reserving space on ships.
