Maritime Contract Governance System

The governance layer for maritime contracts: the one thing we build, held to an institutional standard.

MBN governs a maritime contract from scope to award, and from January 2027, through execution. A single discipline, done deeply: contract governance, and nothing else. Engineered as one robust, intuitive system: not a marketplace, not a directory. Purpose-built for the small-vessel fleet, up to 3,000 GT and 9,000 kW, with the architecture to scale toward unlimited as we grow.

Structured tendering
one defined scope, the same for every bidder
Attributable authority
who decided and when, always on the record
Audit-grade record
every step preserved, defensible later

What's a tender?

In contracting, a tender is a formal, published request for a defined scope of work: the vessel publishes what it needs, qualified providers bid against that exact scope, and one is awarded under recorded authority. It's the discipline of institutional and government procurement, brought to maritime contracting.

Built for your role
MBN works differently from each side of the tender. Pick the path that matches your organization.
For Vessels
The vessel side of a governed tender.
Publish a defined scope, receive bids against that exact scope, and award under recorded authority. Every clarification stays on the tender itself. From owners' offices to chief engineers, governed procurement from the vessel seat.

For Service Providers
Governed tenders, matched to what you do.
MBN Tender Distribution routes tenders to you when your engineering categories and service sub-regions match the scope. You bid against one defined scope, clarify on the record, and receive awards that are attributable, not assumed.

For Management Companies
Arrives Jan 2027
Fleet-wide contract governance.
Every tender, bid, and award across the vessels you manage: traceable, audit-grade, in one place. Governance across the fleet, never crew or maintenance. Management Company accounts arrive in MBN's next phase (~January 2027): portfolio visibility, delegation, and authority attribution.

I've worked both sides of the tender. As an operations engineer, I defined the scope, then watched the approvals and the authority behind it go verbal and unrecorded, until an invoice arrived over expectations and no one could say who authorized what. As a service provider, I put in the proposals, then chased the approvals that lived in someone's inbox. MBN is the system I wanted from either seat: one defined scope, recorded authority, a record that holds up. The discipline of institutional and government procurement, without the bureaucracy.
— Victor De Leon V., MBN Founder
Why MBN exists
Maritime contracting has long run on trust and memory: verbal approvals, authority that's hard to attribute later, scope that drifts without a record. MBN gives that trust a structure: explicit authority, enforced approvals, a record that holds up. Not a digitized version of the old way. A governed one.
What goes wrong today
  • Authority assumed rather than documented: when a decision is challenged, no one can point to who actually authorized it.
  • Financial commitments without enforced approval limits: invoices arrive that exceed any reasonable spending boundary.
  • Scope changes negotiated informally: the original tender and the executed work no longer match, and the change history is in someone's inbox.
  • Warranty periods activated without recorded commissioning: claims surface months later with no defensible start date.
  • Disputes that turn on memory instead of record: resolved by whoever documented best, not necessarily by who was right.
How MBN governs
Operational correspondence is not governance. Email and chat tools exist to coordinate work. They do not establish authority, enforce approvals, or preserve the kind of attributable record that holds up under audit.
MBN introduces explicit authority, formal approval gates, and lifecycle traceability designed to fail closed when required approvals are absent. The intent is institutional discipline at maritime contracting's scale, without the bureaucracy that makes institutional discipline unworkable in practice.
What's live today
Tendering is live. Every tender published through the platform runs the four controls below. No opt-in, no exceptions.
Published scope
A tender is a defined document, not an email thread. Scope, timeline, parameters: written once, published once, the same for every bidder.
MBN Tender Distribution
Tenders are emailed automatically to every service provider whose engineering categories and service sub-regions match the published scope, without anyone maintaining a vendor list.
Recorded clarifications
Questions and follow-ups land on the tender record, not in separate inboxes. When you review bids later, you see the conversation that shaped each one.
Attributable awards
Award decisions are recorded explicitly: who authorized, when, against which bid. The successful provider knows immediately; unsuccessful bidders see the outcome with the same clarity. No implication, no ambiguity.
Assistive by design

AI that drafts. Authority that's human.

MBN's tools do the drafting and the data entry so people can spend their time on the decisions. The Tender Helper turns a plain-language description into a structured scope; the quote reader turns a provider's PDF into a priced, line-by-line bid. The tools prepare the work. Authority always stays with a person.

Live today across the U.S. and the Caribbean.

MBN matches every tender to service providers by engineering category and by service sub-region, so work reaches the providers actually equipped and positioned to do it. Active coverage today spans the United States and the Caribbean.

The platform is built for the Mediterranean and Central America as well; those regions open as our coverage expands.

Arriving January 2027

What arrives January 2027

Once tendering is grounded, MBN extends governance into the rest of the contract lifecycle. Activating in January 2027:

  • Workrooms — the governed execution environment after a contract is awarded. Milestones, evidence submission, and acceptance events tracked under audit-grade records.
  • Change Orders — formal scope expansion, reduction, pricing, or timeline adjustments after execution begins. Submission, review, and approval under explicit authority.
  • Warranty Room — controlled environment for post-execution warranty claims. Activated only after formal commissioning acceptance, with deadlines tracked through a clear closure event.

None of this is live yet. We label it so you can plan, not so you mistake it for what's available today. Each tier page covers the relevant subset in more depth.
