Drewry: Megaships Not Delivering Mega Savings

The economies of scale that have been a key feature of the liner industry, may be running out, shows Drewry’s study of the operational and financial impacts on lines, terminal operators, ports and other supply chain stakeholders as vessel size increases up to and beyond 18,000 teu.

Since 2009, leading container shipping lines have engaged in a new-build ‘arms race’ with vessel sizes increasing at breakneck pace to drive down unit costs and improve profitability. This race-to-scale is set to continue with a further 53 megaships expected to enter service in 2016.

“While bigger ships help carriers reduce voyage costs, these savings are increasingly offset by higher port and landside costs meaning that total system cost savings are small and declining,” Drewry says.

Larger vessels place greater demands on ports, where channels have to cater for deeper draughts and on terminals, which need to upgrade equipment, yard facilities and manning levels to effectively handle increased peak cargo volumes. On a total ‘system cost’ basis the study found that the upsizing of vessels provides only modest savings for the overall supply chain with efficiency gains being further eroded as vessels size increases beyond 18,000 teu.

Drewry expects that even with no further increase in maximum vessel size, the sheer number of mega vessels expected to be delivered in 2016 will strain terminal resources, as the average size of ships increase the amount of cargo that has to be handled at times of peak container activity.

Key findings from the Drewry study:

• Combined shipping line and port ‘total system’ cost savings peak at only 5% of total network costs and economies of scale diminish as vessel sizes rise beyond 18,000 teu
• Terminals will incur significant capital expenditure to handle larger vessel sizes and terminal yard areas will need to increase by one third to avoid congestion, even with no growth in volume
• Scale economies from megaships only work for the total supply chain if terminals can increase productivity in line with increases in vessel size
• Continued vessel upsizing risks, leading to:
– No significant cost benefit, lower service frequency and/or less choice for shippers
– Higher supply chain risks as volumes are concentrated in fewer vessels
– Environmental effects arising from dredging deeper channels and expanding yard area

More megaships driving the industry to a critical stage

“As more megaships enter service the industry is rapidly approaching a critical stage,” said Tim Power, managing director of Drewry.

“To ensure the economics of vessel upsizing continue to benefit the entire supply chain, lines and ports need to work in a more coordinated manner if further productivity improvements from the transport system are to be realised. Addressing the operational and cost effects at port facilities caused by the challenging load and discharge patterns of these larger ships requires a cross-industry effort,” Power said, adding that if this is not achieved the implications are profound.

According to Drewry, there is a wider possible implication of these findings for the industry: if economies of scale in liner shipping have finally run their course, future vessel ordering will no longer be driven by the need to secure economies of scale but will instead be based on lines’ assessment of future demand growth.

“When this happens, the tendency to structural overcapacity that has plagued the industry will be much reduced,” added Power. “If this were combined with a process of continuing industry consolidation, liner shipping might at last be in a position to generate sustainable profitability.”
