The rapid transition toward green energy and sustainable transportation has introduced a complex set of operational challenges for Indonesia’s maritime logistics sector. The Ministry of Transportation has formally addressed ongoing concerns regarding the reluctance of several commercial ship operators to transport electric vehicles across domestic waters. According to regulatory authorities, the hesitation stems primarily from the failure of vehicle owners and logistics providers to meet stringent safety requirements mandated for maritime transport.
These safety protocols are clearly outlined in the Circular Letter (Surat Edaran) of the Director-General of Sea Transportation Number SE-DJPL 12 of 2024. Issued on April 4, 2024, the regulation governs the handling of Indonesian-flagged vessels engaged in the transportation of electric vehicles. The scope of the directive encompasses critical operational standards, ranging from specialized vehicle placement schemes on board vessels to the mandatory implementation of rigorous emergency response procedures at sea.
Background and Context of the Maritime EV Safety Dilemma
As Indonesia aggressively promotes the adoption of battery-powered vehicles to reduce carbon emissions and curb national dependence on fossil fuels, inter-island logistics have faced an unprecedented testing ground. Maritime transport remains the backbone of connectivity in an archipelagic nation like Indonesia, where millions of passengers and cargo units traverse open waters daily. However, the unique chemical and physical properties of lithium-ion batteries—commonly used in modern electric vehicles—pose distinct safety hazards that traditional maritime safety standards were not originally designed to handle.
Lithium-ion batteries carry a risk of thermal runaway, a phenomenon where a damaged or overheated cell can trigger an uncontrollable, self-sustaining temperature increase, ultimately leading to fire or explosion. Unlike conventional internal combustion engine vehicles, fires originating from lithium-ion battery packs are notoriously difficult to extinguish using standard marine firefighting equipment. They require specialized cooling agents, specific containment protocols, and continuous monitoring.
Recognizing these vulnerabilities, the Indonesian government drafted regulatory frameworks to preemptively mitigate potential disasters at sea. However, the transition period has exposed significant friction between transport operators seeking to minimize liability and vehicle owners demanding seamless inter-island mobility.
Chronology of Events and Consumer Complaints
The issue gained widespread public attention following a series of incidents where vehicle owners reported being denied boarding privileges by ferry operators when attempting to transport their electric cars across major domestic shipping lanes. Service users voiced their frustrations across various platforms, prompting the Ministry of Transportation to launch an internal review and subsequently reiterate existing regulatory guidelines to shipping companies.
Samsuddin, the Director of Shipping and Seafarers at the Ministry of Transportation, confirmed that his office continues to receive reports regarding operators turning away battery-powered fleets. "We have indeed received information indicating that several operators remain hesitant to transport electric vehicles," Samsuddin stated.
In response to these complaints, maritime authorities initiated a comprehensive re-socialization campaign directed at ship operators, vessel captains, and port authorities. The primary objective is to bridge the communication gap, ensuring that all technical prerequisites stipulated in the April 2024 circular letter are thoroughly understood and meticulously implemented without compromising navigational safety.
"We issued this circular letter again after receiving complaints from service users regarding several operators unwilling to transport them," Samsuddin explained, emphasizing that the government does not endorse a blanket ban on electric vehicles. Instead, he clarified that the rejections are strictly tied to non-compliance with technical safety thresholds. "There is no prohibition against carrying electric vehicles using maritime transportation. Perhaps, in this case, certain requirements outlined in the circular letter were unfulfilled, leading operators to decline the cargo."
Core Regulatory Requirements under SE-DJPL 12/2024
To ensure transparency and guide both operators and consumers, the Ministry of Transportation outlined specific operational mandates that must be satisfied before any electric vehicle is permitted onto a commercial vessel. These measures are designed to contain potential hazards and provide immediate emergency intervention capabilities:
- Strategic Deck Placement: Electric vehicles must be parked exclusively in designated open-deck areas. They are strictly prohibited from being stowed in enclosed lower car decks, where smoke detection and fire suppression are significantly more challenging.
- Battery State of Charge (SoC) Limits: The energy level within the vehicle’s battery pack must be restricted to a maximum of 50 percent prior to boarding. This limitation reduces the overall chemical energy available and lowers the risk of spontaneous thermal runaway during transit.
- Specialized Mitigation Facilities: Vessels authorized to carry electric vehicles must be equipped with specialized firefighting tools, thermal imaging devices, and containment equipment tailored specifically to the characteristics of lithium-ion battery fires.
"This is something that the public needs to understand. It is not a matter of arbitrary rejection; rather, the safety requirements specified in the circular letter may not have been fully met," Samsuddin noted.
Industry Implications and Future Regulatory Upgrades
The current friction between operators and EV owners highlights broader systemic challenges within Indonesia’s logistics infrastructure. As EV adoption rates climb—supported by government tax incentives, localized manufacturing investments, and expanding charging networks—the demand for inter-island EV transport is projected to surge exponentially.
Shipping operators, operating under strict international and domestic maritime liability laws, are naturally risk-averse. In the absence of comprehensive insurance products specifically designed for maritime lithium-ion transit risks, operators bear the legal and financial burden of potential catastrophic accidents. Consequently, strict adherence to the Ministry’s circular letter serves as their primary legal defense mechanism.
To address these long-term structural needs, the Ministry of Transportation has indicated plans to elevate the current legal framework. While the guidelines currently exist as a Directorate General Circular Letter, authorities are considering upgrading the policy into a more binding legal instrument, such as a Ministerial Regulation (Peraturan Menteri) or a formal Decree of the Director General.
"The next phase will likely take the form of a Director-General Decree," Samsuddin remarked regarding the evolutionary trajectory of the regulation. However, he noted that the government has not yet established a strict timeline for the rollout of the upgraded regulations. Policymakers are deliberately adopting a cautious approach, choosing to monitor international developments and technical benchmarks issued by the International Maritime Organization (IMO).
"So far, the guidelines remain general in nature," Samsuddin concluded, signaling that Indonesia’s domestic regulatory framework will continue to evolve in tandem with global maritime safety standards.
Economic and Logistical Analysis
The implications of these regulatory enforcement measures extend far beyond immediate passenger convenience, touching upon key economic and logistical pillars:
- Logistics Costs and Efficiency: The necessity of open-deck placement and specialized safety gear may limit the volume of electric vehicles a single vessel can carry per voyage, potentially increasing logistics costs for distributors and individual consumers alike.
- Infrastructure Adaptation: Ferry terminals and commercial ports across the archipelago will eventually need to invest in dedicated staging areas, battery diagnostic tools, and rapid-response safety units to support compliant loading procedures.
- Consumer Confidence: Clear, standardized enforcement of safety protocols will ultimately bolster public trust, assuring travelers that inter-island maritime transit remains secure even as the national vehicle fleet undergoes a historic technological transformation.
As Indonesia navigates the complexities of the green energy transition, the alignment between technological innovation and regulatory enforcement remains paramount. The ongoing dialogue between the Ministry of Transportation, ship operators, and the public reflects a shared commitment to balancing modern mobility ambitions with uncompromised maritime safety.
