Port-Call Data-Contract Director — Ocean Shipping

The mandate

Vessels, agents, terminals and port communities publish shifting arrival, berth and completion estimates with different meanings and update discipline. Voyage teams reconcile them by telephone, while fuel and customer systems consume a single timestamp without its confidence or source context. The operator wants contracts tied to decisions, not another message standard that assumes every port and counterparty behaves uniformly.

The deliverable is a Port-Call Decision Data Contract for arrival sequencing, berth readiness, cargo completion and departure. It will define voyage and event identity, status semantics, source precedence, update triggers, confidence, correction, acknowledgement and consumer obligations. Three representative ports must implement a lightweight reference exchange demonstrating value without requiring replacement of agent or terminal systems.

Milestone one in week three maps port decisions, source behaviours and cost of uncertainty. Week seven concludes milestone two with contract drafts and exception states. At week twelve, milestone three supplies live or shadow exchanges across three ports and disruption tests. The accepted contracts, partner playbook, economics and rollout sequence reach sponsors in week seventeen.

Acceptance requires voyage planners to reconstruct fifteen unseen port-call states, explain the source and confidence behind every decision timestamp, and respond correctly to injected berth, weather and agent contradictions. At least two external counterparties must acknowledge obligations. Operations and Fleet jointly sign after an internal team runs a complete call replay without consultant interpretation.

The client will provide voyage plans, AIS histories, agent updates, terminal messages, statement-of-facts records, fuel decisions, customer promises, interface terms and disputed calls. Port captains and planners will join observation; partner managers will secure counterparties. Client engineers implement exchange changes, while the fleet chief resolves contested event meaning and safety boundaries.

Why this is external work

Experienced operators compensate for ambiguous messages through relationships, while integration teams see standard formats rather than local port practice. Agents and terminals have different incentives to update forecasts, making unilateral internal rules ineffective. External work can broker practical obligations across counterparties and preserve human maritime judgement instead of pretending a canonical timestamp removes uncertainty.

What you will own

• Map arrival, anchorage, pilot, berth, cargo, service and departure decisions to evidence produced by vessel, agent, terminal and port systems.
• Define event identity, occurrence time, forecast horizon, status, confidence, source precedence, correction and acknowledgement for each critical update.
• Create exception states for weather, congestion, berth reassignment, incomplete cargo, missing agent response and conflicting official notice.
• Specify consumer behaviour so fuel, voyage, crew and customer systems respond appropriately to confirmed, forecast and disputed information.
• Trial contracts in three ports with different digital maturity, counterparties and operating constraints through shadow or live exchange.
• Quantify value through reduced waiting, avoided fuel, fewer manual chases, better customer communication and lower integration exception effort.
• Transfer counterparty onboarding, contract change, dispute review and rollout prioritisation to permanent fleet and data owners.

Candidate qualifications

• Designed maritime, aviation or logistics data contracts across independent physical operators with divergent systems and incentives.
• Led port-call or voyage optimisation where arrival and berth uncertainty influenced fuel, charter, customer or operational decisions.
• Modelled forecast, confirmed and disputed states without allowing one technically valid timestamp to erase human operating context.
• Negotiated practical data obligations with agents, terminals and port communities that lacked a common platform or maturity level.
• Tested partner behaviour through real calls or faithful shadow operation rather than relying only on interface-schema conformance.
• Delivered a rollout and operating model internal fleet teams could sustain after the external design engagement ended.

Non-negotiables

• The named director must work in Athens and observe representative vessel and port-call operations throughout the pilot.
• No referral, platform resale, agency ownership or success payment may influence port or technology selection.
• Masters, pilots, terminals and port authorities retain all navigation and safety decisions irrespective of data-contract status.
• Commercially sensitive voyage and counterparty records must stay in approved client environments and permitted ports.
