MARPOL Redux: Look Back, because Something may be Gaining on Us

Amidst the IMO sustainable fuel regulation highs and lows there are other parts of the maritime regulatory environment that may warrant a closer look.
For roughly a century, maritime relied on liquid fossil fuels. Meanwhile, it took over half a century for regulations to start to deal with the negative effects of liquid fossil fuels and to effectively deal with maritime fossil fuel disasters.
The star player in this effort was OPA90, which, once implemented, massively reduced the negative effects of liquid fossil fuel damages.
Today we are standing on the precipice of the introduction of a huge number of more sustainable fuels, each with their own peculiarities and potentials for public and environmental harm.
Rather than rushing through regulations after the horse has left the barn for each sustainable fuel, this may be time to take the OPA90 approach and adapt it for the incoming fuels.
OPA90 was the lead for liquid fossil fuels regulations, and this effort resulted in various follow up efforts such as MARPOL double hull requirements, SOPEP and specific national responses. Many non-U.S. national response regulations have taken many pages from the U.S. playbook.
In retrospect this became an assortment of regulatory sausages.
This has also become evident when one considers that in the United States pieces of the OPA90 approach such as the Joint Incident Command System are now also applied in non-pollution related disasters such as the Dali/Key Bridge incident.
That speaks well for the conceptual success of the OPA 90 approach but does not mean it will not result in miscommunication and response delays in future sustainable fuel disasters.
When considering fuels, it is important to realize that, in maritime, fuels and cargo are actually the same thing. OPA 90 related to oil cargoes, but the adoption of SOPEP centered on the realization that many ships can carry as much oil for fuel as other ships carry in cargo.
In this regard a single regulatory model that includes cargoes and fuels of any kind and provides specific responses to the hazards of those cargoes and fuels would make sense.
In this regard the International Dangerous Goods Code provides a frame work for classification and handling of goods, but not for remediation in disasters. Some of the sustainable fuels would fall under this code and others would not, but it is unclear if this regulation applies to these goods if carried as fuel.
What all of this appears to argue is that the industry could benefit from a regulatory swamp drain and rationalize an approach that is linear and fully inclusive in its application.
Such an approach would do the following:
- Define what situations can result in general disasters with damage to property and the public (spills, groundings, hurricanes, tsunamis, melt downs, collisions, allisions, fires, explosions)
- Define what is carried aboard ships and categorize the hazards and preventative measures with those fuels and cargoes (that can include deck cargoes, lost containers, cars and lithium batteries)
- Outline a general response approach (Joint Command System, etc.)
- Outline specific response modifications for specific fuels and cargoes including environmental impacts and remediation challenges (salvage and environmental response per type of cargo and type of ship)
- Set approved user requirements (cargo and fuel shipboard prevention and response, Vessel Response Plan, SOPEP manual, approaches for autonomous vessels, etc.)
- Set approved responder requirements similar to Area Response Plans, vessel Salvage Marine Fire Fighting (SMFF) regs, etc.
- Set a standards for reimbursement of damages and response (Insurance and SCOPIC style standards)
- Set standards for enforcement. (limits to criminal prosecution and crew retentions, responder hold harmless, and federalization)
The realization of this approach would probably be a long-term industry wide IMO level effort, but a first pass will identify and categorize the various components and build a road map for detailed evaluation.
There is no doubt that much, if not most, of the above components have at one time or another been examined, activated and exercised under OPA90. OPA90 Forum is an organization that has hundreds of years of experience with OPA90 activities. In this regard a logical choice to make this first effort would be a working group organized under OPA90 Forum.
For every column I write MREN makes a small contribution to an organization of my choice. For the foreseeable future I am selecting SL7Expo. An industry wide effort to develop a Smithsonian level exhibit center for commercial maritime.

Facts Only

* The article discusses the need for a revised regulatory approach to maritime disasters, particularly those involving new sustainable fuels.
* For roughly a century, liquid fossil fuels dominated maritime transport. Regulations to address their negative impacts developed over half a century.
* The OPA90 (Oil Pollution Act of 1990) significantly reduced the impact of oil spills and became a model for subsequent regulations like MARPOL double hull requirements and SOPEP (Solvent Oil Pollution Prevention).
* The regulatory approach developed around OPA90 has evolved into a “assortment of regulatory sausages,” illustrating how regulations can become fragmented and applied across diverse situations.
* The Dali/Key Bridge incident in the United States demonstrates the applicability of the OPA90 approach beyond pollution response, highlighting both its conceptual success and potential for miscommunication.
* Maritime fuels and cargoes are essentially the same thing, requiring a unified regulatory approach.
* The International Dangerous Goods Code provides a framework but lacks specific remediation guidelines for sustainable fuels.
* A proposed regulatory “swamp drain” suggests a single, inclusive model for managing maritime disasters, regardless of cargo or fuel type.
* The proposed model would include defining disaster scenarios, categorizing hazards, outlining a general response approach, and setting specific response modifications for fuels and cargoes.
* It would also establish approved user and responder requirements, standards for damage reimbursement, and enforcement mechanisms.
* The OPA90 Forum is proposed as a key organization to initiate this comprehensive effort.

Executive Summary

The article argues for a renewed regulatory approach to maritime disasters, drawing a parallel to the development of the OPA90 regulations following the widespread use of liquid fossil fuels. It suggests that the industry’s reactive, piecemeal approach to addressing new sustainable fuels—like the current efforts around MARPOL—risks repeating past mistakes. OPA90’s success in reducing oil spill damage through comprehensive regulations, including the requirement for double-hulled ships and detailed response protocols, is presented as a blueprint. However, the article warns that this fragmented approach, resulting in “regulatory sausages,” could lead to confusion and delays in responding to disasters involving novel fuels. The proposed solution is a unified regulatory model that would encompass all cargo and fuel types, outlining specific hazards, preventative measures, and response protocols. This model, rooted in the principles of the Joint Incident Command System, would aim to streamline disaster response and ensure consistent standards across the industry. The article emphasizes the importance of proactive regulation rather than reactive adaptation.

Full Take

The article is a sophisticated, if somewhat understated, critique of the maritime industry’s historical tendency towards reactive regulation and its potential vulnerability to future disruptions posed by sustainable fuels. It deftly uses the OPA90 narrative – a story of belated but ultimately effective action – to frame a call for preventative, holistic regulation. The core pattern here is the cyclical nature of industrial response to environmental crises: initial denial, then fragmented, siloed regulations, followed by belated, often insufficient action. The “regulatory sausages” metaphor vividly illustrates this process, suggesting a bureaucratic bloat and lack of integration. The framing of fuels as “the same thing” – cargo and fuel – is a brilliant move, designed to disrupt the industry’s ingrained silos of thinking about oil versus other substances. This opens the door to a truly systemic approach. However, the reliance on the OPA90 model introduces a subtle bias: the assumption that a “command and control” approach, while effective in one context, will automatically translate to others. The potential for miscommunication and response delays, even with a well-defined system, is a significant caveat. The article subtly highlights a systemic risk: the industry's history of absorbing and repurposing successful regulations—like the Joint Incident Command System—suggests a capacity for unintended consequences and a lack of critical distance. It's a sophisticated defense against overly simplistic solutions, designed to encourage a more nuanced, adaptive approach. The proposed “regulatory swamp drain” – while laudable in intent – could easily become another bureaucratic layer, potentially slowing down innovation and resilience. The underlying assumption is that centralized control is superior to decentralized, agile responses, a premise ripe for challenge. The invocation of SL7Expo, a Smithsonian-level exhibit, is a classic “solutionist” gambit—a seemingly noble aspiration designed to frame a complex problem within a technologically-driven framework. The detected pattern is ARC-0024 Ambiguity: the author relies on broad generalizations about “disasters” and “hazards” without fully defining these terms or acknowledging the inherent uncertainties in predicting and responding to complex events. A deeper dive would reveal significant operational and technological gaps. This narrative operates primarily at the level of strategic risk, overlooking the crucial role of human judgment, adaptability, and on-the-ground expertise in a rapidly evolving technological landscape. It is likely driven by a desire to avoid future crises by preemptively establishing controls, a very common, and ultimately precarious, approach.
