Special Topics Riding the Same Wave

Every lesson so far has told one story in different clothes: technology arrives on ships faster than the rules written for it. Connectivity came, and MSC.428(98) followed years behind; the IACS resilience requirements later still. Autonomy is sailing ahead of its mandatory code by roughly a decade. This closing lesson looks at the same pattern where it is burning hottest, literally, and then at the work plans that show where the wave breaks next.

Electric vehicles on the ro-ro deck

Electric vehicles are ordinary cargo on extraordinary chemistry. A modern EV carries a large lithium-ion battery, and lithium-ion cells fail in a distinctive way: thermal runaway, a self-sustaining reaction in which a failing cell's heat pushes its neighbours past their own failure point, venting flammable gases as it spreads. Three properties make this a maritime problem of the first order. Runaway fires are hard to extinguish, because the reaction generates its own heat and fuel; they produce dense, toxic, flammable vapour clouds in exactly the closed deck spaces ro-ros are built from; and they can reignite hours or days after appearing dead, as damaged cells re-heat. A car deck is a low, densely packed, ventilated steel cave: an environment that rewards early detection and punishes delay.

The response playbook, as industry practice has settled it, with the ABS advisory on best practices for the transport of electric vehicles (June 2022) as one of its clearest statements, works the levers a ship actually has:

• Stowage: designated areas for EVs, planned access for firefighting, and attention to what is parked around them.
• Detection: the earlier a failing pack is noticed, the more options remain: video monitoring of the decks and thermal imaging on patrol buy the minutes that matter.
• Firefighting: large quantities of water, applied not to extinguish the chemistry, nothing extinguishes it, but to cool the pack and its neighbours until the reaction starves, with boundary cooling around the space and a reignition watch afterwards.
• Charge and condition: stored energy is the hazard, so state-of-charge limits appear in much carriage guidance beyond the ABS text, and ABS itself wants damaged vehicles stowed in a designated area, on the weather deck where the ship has one.
• Training: crews drilled on how a battery fire differs from the car fires they trained for: the reflexes are close, but not the same, and the differences are exactly where casualties happen.

If that list feels structurally familiar, it should: identify the asset, detect early, respond with what preserves the ship, plan for recovery. The resilience grammar of Lesson 2 is not a cyber invention: it is how shipping absorbs any new hazard.

Reading the regulatory horizon

Where are the rules? Coming, on the industry's usual schedule, and on two tracks. For vehicles as cargo the work sits with IMO's ship systems and equipment sub-committee: SSE 12 (March 2026) put interim guidelines first, on fire safety for pure car and truck carriers and on video monitoring and detection systems, with any SOLAS amendments expected to enter into force on 1 January 2032 at the earliest. The wider work plans, summarised in DNV's briefing on SDC 12, show the same rhythm across the horizon: SOLAS provisions allowing lithium-ion batteries as a ship's main source of electrical power, targeted around 2028, wind propulsion around 2029, and nuclear power from around 2030 onwards, alongside work on quieter ships and composite structures. The dates matter less than the shape: each topic gets an experience-gathering phase, then guidelines, then binding text. In the gap, advisories and class guidance are the operative rulebook, which is why an operator who can read class guidance critically is never waiting for regulation to tell them what competent looks like.

The habits that transfer

This course ends where it began, with a habit rather than a fact. Ships became hackable because useful technology arrived without a security question attached; car decks became chemistry labs because useful cargo arrived without a firefighting question attached. The defence is the same each time, and it is not any single rule: it is the operator's discipline of asking, early, what happens when this misbehaves, and what do we do in the hour after? Applied to a network, that question produced E26, drills, and guarded remote doors. Applied to a battery, it produces stowage plans, thermal cameras, and cooling water. Applied to whatever arrives next, and the work plans above tell you roughly when it arrives, it will produce the answer before the casualty does. That habit, more than any clause cited in these six lessons, is what this course hopes you take back to the ship.
