Additive-Manufactured Marine-Spare Board Adviser

The mandate

Vessels lose operating time waiting for low-volume brackets, covers, impellers and legacy service parts to cross continents, while additive-production vendors promise same-port manufacture from a digital file. Yet part criticality, design ownership, revision, approved material, printer process, inspection route and vessel schedule must align before a locally made item is a legitimate spare. Directors need an independent operating view of which use cases deserve investment, how conventional stock and emergency supply remain available, and whether apparent lead-time savings survive approval, failed prints, customs and last-mile handoff.

Three days a month support the board, but the evidence is organised around six specific handoffs rather than recurring generic reviews: two vessel need cases, two controlled production-workshop observations and two port-agent deliveries. Five committee sessions decide use-case entry, hub qualification logic and portfolio limits. Between sessions the adviser provides a short exception memorandum only when a proposed part changes safety, custody or vessel fallback assumptions. Technical management, class, flag, OEMs and authorised inspectors continue to make every formal approval.

Nine months cover selection of the first part families, observation of two complete digital-to-vessel journeys and the fleet investment decision. The appointment stops after a closing paper records eligible and prohibited archetypes, file and material controls, production-hub capacity, inspection and logistics dependencies, conventional fallback, whole-event economics and unresolved liability. Renewal is unavailable for ordinary additions to the parts list; only a new vessel class or material process may support a separately approved term after a fresh conflicts review.

The adviser carries no line authority, executive responsibility, design approval, class or flag role, purchasing delegation, part-release right or board vote. Challenge may include rejecting a use case from the board portfolio or asking management to preserve physical stock despite longer nominal lead time. The adviser cannot release a file, approve a drawing or material, select a print bureau, sign inspection, direct a vessel, clear customs, fit a component, determine seaworthiness or represent regulatory and insurer acceptance.

Interests in ship managers, owners, OEMs, design-file platforms, additive-machine or powder providers, production bureaux, inspection firms, classification societies, port agents, couriers, insurers and investors must be disclosed. A mandate for a bidder, rights holder or compared manufacturing hub requires recusal from that part family and all proprietary files. The chair may retain the adviser on unrelated cohorts only after documenting separation. The monthly retainer never depends on printed volume, vendor award, claimed lead-time reduction, vessel departure or avoided off-hire.

Why the board wants this voice

Engineers can judge parts and procurement can compare prices, but the board lacks someone who has owned the full operational consequence between a vessel need and a verified onboard spare. Independent challenge can distinguish credible distributed supply from a technology showcase while leaving design, inspection and maritime authority intact. The adviser also tests when conventional inventory is the more resilient answer.

What you will own

• Press management to trace each candidate from vessel failure mode and part identity through design rights, revision, approved material, production slot, inspection, transport, onboard receipt and authorised use.
• Test part archetypes by safety criticality, geometric complexity, demand rarity, file maturity, material availability, post-processing, inspection lead time and conventional fallback.
• Challenge lead-time claims that omit failed build, queue, powder or feedstock constraint, destructive test, customs, port cut-off, agent custody and vessel schedule change.
• Examine cyber and commercial boundaries for file release, access duration, local reproduction, revision withdrawal, production evidence, rejected output and intellectual-property leakage.
• Shape board gates for part-family eligibility, controlled case, production-node reliance, additional material process, fleet replication and withdrawal after failure.
• Maintain an independent record of conflicts, prohibited parts, evidence gaps, failed builds, fallback use, conditions, management disagreement and dissent.
• Leave the committee a portfolio view connecting accepted onboard availability, conventional-stock consequence and complete event cost to each proposed use case.

Candidate qualifications

• Has governed marine technical supply, additive spare deployment or another regulated distributed-manufacturing service from need through approved use.
• Can evidence a print-near-demand proposal changed after design rights, material, inspection or vessel-handoff constraints became known.
• Understands vessel spare criticality, digital file custody, additive processes, post-processing, inspection, class and flag interfaces, ports and emergency procurement.
• Has challenged technology and maritime executives while preserving engineering, OEM, inspection, vessel-command and regulatory authority.
• Can distinguish printable geometry, authorised file, conforming production, inspection-accepted part, onboard custody and approved installation.
• Is independent of relevant owners, OEMs, print platforms, equipment and material vendors, bureaux, inspectors, class societies and insurers.

Non-negotiables

• Can provide three days a month, five committee sessions and six controlled vessel, workshop or port-handoff observations.
• Will not release design files, approve parts or materials, select printers, sign inspection, direct vessels or imply class acceptance.
• Brings direct marine-service supply or regulated additive deployment; manufacturing-technology investing alone is insufficient.
• Will disclose owner, OEM, platform, bureau, material, inspection, class, port, insurance and investment relationships before part review.
