The verdict in three sentences
A useful website specification for an offshore wind components supplier fits in about a dozen pages and sets measurable requirements: page count, file size limits, load times, support response times. With a 2026 market budget of EUR 18,000 to 50,000 and 10 to 16 weeks of work, the template below lets you compare three agencies on numbers rather than impressions. The sections that most often decide the winner are the tender enquiry form with drawings up to 50 MB and the quality and certification pages.
The context to set out on page one
The sales manager of a Dublin based supplier of fabricated and machined components for offshore wind foundations, secondary steel and turbine assemblies is preparing to brief three agencies. Buyers are developers preparing Irish Sea projects, tier one contractors and turbine OEMs who prequalify suppliers on paper. The site must prove capacity, project references and the quality system. Ireland's offshore pipeline means many buyers are visiting the site for the first time, often from the UK, Denmark or Germany.
Accessibility is now a procurement topic too: the European Accessibility Act applies to a range of products and services from June 2025, and large buyers increasingly ask suppliers about WCAG conformance. Check what applies to you; aiming for WCAG 2.1 AA on key pages is a sensible baseline.
The template, section by section
| Section | What you fill in | Measurable requirement to set |
|---|---|---|
| 1. Company and goals | Activity, markets, numeric goals | Example: 12 qualified tender enquiries per quarter within 12 months |
| 2. Audiences | Developers, tier one contractors, OEMs, procurement | One journey per audience, reachable in 2 clicks from home |
| 3. Sitemap | 20 to 40 pages: capabilities, processes, projects, quality, careers | Page list attached, each page with one goal |
| 4. Project references | Projects supplied, components, approved photos | Reference template, at least 6 at launch |
| 5. Quality and certification | Current certificates, qualified welding procedures | Downloadable certificates with expiry dates shown |
| 6. Tender enquiry form | Fields, recipients, attachments | Drawings up to 50 MB, PDF, DWG and STEP, automatic acknowledgment |
| 7. Languages | English, optionally Irish or German | Native review, language switch on every page |
| 8. Technical constraints | Hosting, CMS, security | Under 2.5 seconds mobile load time, daily backups |
| 9. Schedule and budget | Target date, range | 10 to 16 weeks, budget stated as a range |
| 10. Response format | Expected proposal content | Days per line item, comparable references |
Stating a budget range does not weaken your position: it stops you receiving EUR 9,000 and EUR 65,000 proposals for the same brief.

Illustrative example: Ciarán, sales manager at an offshore wind components supplier in Dublin, 140 staff, 28 pages to plan, 6 project references, stated budget EUR 25,000 to 40,000.
- Writing the spec with the template: 3 days of his time, about EUR 2,100 internal cost.
- Three proposals received: EUR 24,000, EUR 33,500 and EUR 46,000. Scores out of 100: 68, 86 and 80.
- Choice: the EUR 33,500 proposal, top scored, with EUR 180 a month of maintenance.
- Goal: 12 qualified tender enquiries per quarter; a single EUR 300,000 order for secondary steel is about 9 times the website budget.
FAQ
How long should the specification be?
Ten to fifteen pages is enough for a 20 to 40 page site. Longer documents get skimmed and the answers become vaguer.
Should we tell agencies our budget?
Yes, as a range, for example EUR 25,000 to 40,000. It filters out mismatched proposals and speeds up comparison.
Why require 50 MB attachments?
Buyers send 3D models and heavy specifications. A form capped at 10 MB loses enquiries or pushes them to email.
How many agencies should we brief?
Three gives a useful comparison without overloading your team. Allow 3 weeks to respond and a 45 minute pitch each.
What belongs on the quality page?
Current certificates with expiry dates, qualified processes and a quality contact. Review it at least once a year.
