Prototype + test support
A prototype is most useful when it answers a specific question about fit, load path, materials, build method, installation, operator use, or performance. Define the question, the evidence needed, and what happens next before choosing what to build.
Prototype basis
A coupon, fixture, mockup, subassembly, or installation-fit article may answer the question without building the complete product. The prototype plan should state what the article will prove, what it will not prove, and how the findings will change the next configuration.
Define the operating problem, platform interfaces, load cases, geometry, materials, environment, human use, build constraints, and acceptance checks. Identify the uncertainty that blocks the next decision and select a prototype that isolates it.
For supplier-built mounts, frames, foundations, rails, racks, consoles, panels, deck components, and enclosures, define the interfaces, materials, attachments, corrosion controls, fabrication access, inspection points, and service needs. Include fabricator input before the package is finalized when weld sequence, fixturing, or distortion can affect fit.
For supplier-built panels, shells, hatches, fairings, housings, ducts, and covers, define the geometry and manufacturing route together. Record the material system, core, reinforcements, inserts, bonds, tooling, process controls, inspection, repair access, and qualified review inputs required by the project.
Organize the load cases, support conditions, parent structure, joints, attachments, material assumptions, failure modes, and acceptance criteria needed by the qualified reviewer. Keep the review assumptions tied to the geometry and build information used for the article.
Use physical measurements or owner- or partner-provided scan data where needed. Provide the defined build information to the selected fabricator or composite shop. Support the build, fit checks, installation, and planned test, then record discrepancies and update the configuration from the findings.
What the project receives
Product requirement, interfaces, risks, acceptance checks, and required evidence
Models, drawings, material, process, and build information
Fabricator, installation, inspection, and test package
Observed findings, discrepancies, and updated configuration
Review basis
Identify the owner, OEM, contract, ABYC, ISO, AWS, class, flag, material and process, and regulatory criteria that apply to the article and its intended use. State the required evidence, reviewer, and test or review that will confirm each requirement has been met before testing begins. Regulated calculations, structural substantiation, certification, and authority acceptance remain with the qualified or authorized party responsible for them. Weld procedure or personnel qualification and laminate approval remain with the qualified or authorized party responsible for those decisions.
