What the text actually does.What the negotiation actually means.What the decision actually requires.

Senior advisory on international public law, the law of the sea, ocean governance, and the blue economy — for those operating where the gap between legal framework and political reality is not a theoretical concern but a strategic one.

Why
Ordinem

The available material on ocean governance is not scarce. What is scarce is writing and advice that explains what actually happened, why it matters structurally, who is maneuvering and under what constraints, and what the second-order consequences are. Ordinem International exists to provide that — to states, institutions, and organisations that cannot afford to mistake description for understanding.

02 / How we work

An exacting standard at every stage

Understand

We begin by listening — not to confirm what we expect to hear, but to establish precisely what decision you are facing, what constraints you are operating under, and what the existing available advice has failed to provide. The gap between what clients have already read and what they actually need to understand is where our work begins.

Analyse

Rigorous analysis of the legal, geopolitical, and institutional landscape — not as a description of events but as a structural account of why things are happening, who is maneuvering under what constraints, and what second-order consequences follow from the available courses of action. We draw on direct experience at the highest levels of international law and maritime affairs, and we deploy it with the doctrinal precision and negotiation literacy that transforms proceedings into strategic understanding.

III

Advise

Clear, direct, and actionable counsel — including the things that are uncomfortable to say. We will tell you when the consensus is performative, when implementation architecture is underdeveloped, and when the gap between what states have agreed to and what they are doing is the most important strategic fact in your situation. We do not hedge. We identify the path most likely to achieve your objectives and set out the risks of each course with institutional honesty.

Accompany

We remain present through implementation. Strategic advice has no value if it cannot be sustained through the complexity of execution — through the procedural disputes, the coalition shifts, and the distance between what was negotiated and what is being delivered. We stand alongside clients at every stage.

03 / How we engage

Four forms of engagement

Ordinem International's work is delivered across four forms of engagement. Each is available across the full scope of our practice areas — the nature of the question, not the subject matter, determines the appropriate form.

Written Advisory Products

The Rapid Briefing

For clients who need precise interpretive clarity before a specific moment — a negotiation session, a ministerial briefing, a funding decision, a board presentation, or a public position that needs to be defensible. It tells you what is actually at stake, who is maneuvering under what constraints, what the realistic outcomes are, and what position is strategically defensible.

Two to four pages · Delivered within five working days

The Strategic Memorandum

For clients who need interpretive precision on a defined legal or policy question. Not a landscape analysis and not a moment-specific briefing — a rigorous written answer to a specific question whose implications are not yet fully understood. What does this provision operationally mean? What precedent does this procedural decision create? How does this instrument interact with existing obligations?

Five to ten pages · Scoped per engagement

The Negotiation and Institutional Assessment

For clients facing a consequential decision about how to engage with, fund, oppose, implement, or litigate a specific instrument, institution, or negotiating process. Three parts: the institutional landscape as it actually operates, the strategic environment including who is maneuvering and under what constraints, and an honest assessment of the client's position, options, and exposure.

Fifteen to thirty pages · Scoped individually following initial consultation

The Position Paper

A written document prepared for a client to submit, present, or defend — in a negotiation, before a Conference of the Parties, at a ministerial meeting, or in a dispute context. Drafted in the client's voice, reflecting the client's interests, grounded in the legal and institutional analysis that makes it defensible. The output is the client's document, not our analysis.

Scoped individually · All formats and lengths

Project Engagements

On-the-ground. Multi-phase. Outcome-oriented.

Project engagements are defined by how the work is delivered rather than what it contains. Where written advisory products respond to a question or a moment, project work involves sustained presence — direct collaboration with government counterparts, ministries, regional bodies, or institutions over a defined period, with an institutional or policy outcome as the deliverable rather than a document.

Projects we undertake include governance architecture and institutional development, national ocean policy design, blue economy regulatory frameworks, treaty implementation support, and capacity-building programmes for states and regional organisations. Each engagement is scoped individually. The form the work takes follows from what the client needs to build.

III

Ongoing Engagement

The Retainer

Monthly or quarterly access to senior advisory capacity for clients with recurring decisions, who need standing interpretive support across a negotiating cycle, or who want priority access without commissioning discrete engagements each time. Includes defined advisory hours, priority response, early access to Deep Brief issues, and one Rapid Briefing per quarter.

Monthly or quarterly · Reviewed at renewal

Delegation Support

Direct presence alongside a delegation at a Conference of the Parties, an ISA session, an intergovernmental conference, or a negotiating round — providing real-time interpretive support, drafting assistance, and strategic counsel in the room. Event-based and scoped to the specific meeting or session.

Event-based · In-room presence · Scoped per session

05 / Our People

Advisers of uncommon depth

Ordinem International is built on a model that is deliberately compact by design. We do not deploy large teams or intermediary layers. Every engagement is led by a senior adviser with direct, substantive experience at the highest levels of international law, ocean governance, and maritime affairs — not delegated to it.

The seniority of our counsel is not incidental to the offering.
It is the offering.

International Legal Practice

Careers shaped in international courts, treaty bodies, and intergovernmental processes at the frontier of public international law and the law of the sea.

Ocean Governance & Policy

Direct engagement with the institutional architecture of ocean governance — UNCLOS, IMO, ISA, the BBNJ process, and regional ocean bodies — at the most senior levels.

Blue Economy Advisory

Practical understanding of the legal and regulatory landscape for sustainable ocean industries — from fisheries and offshore energy to deep-sea resource management and maritime finance.

We operate with full discretion. We do not publicise client relationships or adviser identities without explicit consent. Those who engage us do so precisely because we maintain the highest standards of confidentiality in every matter we handle. Enquire in confidence

06 / Insights

Thinking that
goes further

Ocean governance moves fast and is poorly explained. Negotiations produce outcomes that official summaries describe but rarely interpret. Legal instruments are adopted whose implications practitioners cannot fully decode. Ordinem International publishes The Deep Brief and produces advisory analysis for clients who need to understand not just what is happening but what it means — for the institutions they work within, the decisions they face, and the operating environment they will navigate over the next five years.

The Lawless Sea?

The UNCLOS framework was among the most ambitious legal instruments ever negotiated. For several decades, it broadly held. What has changed is not the text — it is the willingness of powerful states to treat the obligations it creates as genuinely constraining.

Issue 02 · 15 June 2026 · Free to subscribers

Too Little, Too Late?

The BBNJ Agreement is the most significant development in the law of the sea since UNCLOS entered into force in 1994. It is also arriving into an environment that may not sustain it.
