Autonomous ships - Whilst Iβve covered autonomous vehicles fairly consistently, Iβve yet to pay much attention to other modes of autonomous transport, for which there are many. Last week Vice posted
an interesting short documentary on autonomous marine craft being developed by Boston-based
Sea Machines Robotics.
Whilst the global shipping industry, which is approximately $12tn in size, might seem like the likely adopter of automated unmanned sea craft. In the near-term, thatβs unlikely to be the case:
>> Letβs think about ride hailing; the driver is likely to earn 1x to 4x times the cost of the vehicle annually. The driver is limited to driving 1 to 3 passengers at any one time and as such is unscalable. Taking up to 50% of Opex, the driver is by far the biggest cost on a per ride basis. Therefore, the incentive to replace the driver with an autonomous system is high - both in the short and long term.
>> The biggest cost levers in shipping beyond the ship itself is fuel costs. The crew also contribute to fuel costs through the use of electricity and space used for crew quarters which adds weight and air resistance. The reduction in these would only likely constitute a 5% to 7% savings on operational costs. This saving is fairly paltry in comparison to the high cost of a new autonomous asset, which even whilst retro-fitted might be 10%+ of the ships value / new ships would be significantly more. Currently, it only makes sense to think about autonomous ships as being fully unmanned or else the savings quickly trend to zero. Another considerable cost in shipping is insurance, many of these ships are carrying hundreds of million dollars of often corrosive cargo. Whilst 80% accidents are caused by human error - not having any humans aboard in order to mitigate certain incidents provides some headaches. Most importantly, itβs difficult for current insurers to accurately model and price insurance premia of autonomous ships. Currently the economics of large scale autonomous doesnβt add up.
It may be more interesting to look at replacing much of the fuel costs and drivetrains of these ships, with electric solutions. Currenlty, ships use Heavy Fuel Oil (HFO) which is cheap, dirty and requires a lot of human intervention to run consistently. Whilst Donald Trump might not believe in them we should expect to see increasing quotas around the use of combustable fuels, especially as shipping is the
single worst global polluter.
So what does this mean for autonomous ships?
Last week, Norway launched the first autonomous passenger and car ferry - check out the
video. The ferry operates daily within a pre-defined route and timetable.
In the short term, weβre going to see more autonomous ships operate within waterways such as ferry routes, archipelagos, coastline patrols and inter-city riverways. These are comparatively low-risk, low-cost and high usage use cases.
