Fully-Electric, Intelligent Containership in Service

China has put in service a fully electric 740-TEU containership, the first of two. The vessels are equipped with 10 container-sized batteries with a total power supply of approximately 19,600 kWh. They supply two 875 kW permanent-magnet synchronous propulsion motors. Reports have said the ships will have a top speed of approximately 11.5 knots. The battery containers are swappable so that ships can ‘refuel’ at a quick stop.

The two planned vessels also have fully autonomous navigation capabilities.

This is the kind of advance we ought to see in every large maritime nation. For the US it would be useful to replace barge traffic on the Mississippi with electric propulsion using battery packs. While autonomous navigation would not be much use there, fully electric power would cut emissions to as low as they could go. Short-haul traffic elsewhere could also profit from such designs. Inland shipping in particular is a good target.

Investing in this type of ship is a way US shipbuilding could vault ahead. It could become the go-to place for battery electric designs. While China will still have a lead because of its early leadership in battery power and storage, the US could make a targeted move to catch up on specific designs.

Where are the entrepreneurs for this kind of effort?

Bangladesh and the HKC: Standards for Ship Recycling

Shipbreaking has always been dirty and dangerous work. For years it was performed under inhospitable working conditions, in countries where legal protection for workers was not strong. Then the Hong Kong Convention (HKC) for the Safe and Environmentally Sound Recycling of Ships became effective in June of 2025. That changed things. Now there is clear international law marking how recycling yards must operate if they want to handle the world’s discarded ships.

Bangladesh is the largest ship-recycling state, with many facilities, and much tonnage recycled into scrap steel and other by-products. The government has drafted new Ship Recycling Rules 2025, to assure that their recycling yards are compliant with both Bangladesh law and with the HKC. And these rules have been receiving some criticism.

The opinion piece linked below, by a prominent Bangladeshi professor and ship-recycling expert, debunks that criticism. It seems that Bangladesh has managed to thread the needle, creating a legal structure that will support compliant shipbreakers, while giving noncompliant facilities a chance and a time window to become compliant. And it’s done in a way that will not allow the noncompliant yards to persist in a rogue fashion.

The law should be welcomed by the shipping community. Bangladesh is a preferred location for shipbreaking because of its ideal geographical setting and better cost profile. A rising tide of scrapping is coming, because of the need to improve environmental characteristics of ships, and an oversupply created by a newbuilding splurge. Bangladesh needs to be included in the roster of decent places to recycle ships.

Bulk carriers and containerships moving at slowest speeds

Slow steaming is a good way to save on fuel costs and meet the new IMO requirements. So ships have slowed down. But I was amazed at the graph below, showing a trend for quite a while.

Slowing down is an important way of cutting CO2 emissions from fuel oil. It also implies that more ships are needed to meet planned sailings on a scheduled route. It’s a deliberate reduction of individual ship ‘productivity’, since fewer paid cargo-carrying trips can be made in a year. But it may be a better fit with the demand for shipments right now, and it might result in fuller vessels.

We should remember that slow steaming will not eliminate CO2 emissions problems; it’s a stopgap at best. New types of power with very low or zero emissions through their life cycle well-to-wake must be developed. The investments have to be made.
