The verdict in three sentences
For an offshore services company (marine logistics, inspection, maintenance) based in Amsterdam, a credible corporate website costs 15,000 to 46,000 EUR in 2026. The budget should first fund HSE and certification pages and a secure document portal where buyers from energy majors download your certificates without email back-and-forth. Delivered in 3 to 5 months, in English and Dutch, it shortens supplier qualifications and carries weight in tenders.
The budget line by line
Buyers at oil and gas operators and offshore wind developers assess a contractor before they even send a qualification questionnaire. They look at your capabilities, your safety statistics and how current your certificates are. A generic brochure site does not pass that filter.
| Item | 2026 cost (EUR) | What the buyer finds there |
|---|---|---|
| Strategy, architecture and bilingual design | 3,000 to 8,000 | An image aligned with operator standards |
| Capability pages (marine logistics, inspection, maintenance, base) | 3,000 to 10,000 | Assets, crews, operating areas |
| HSE and certification pages (ISO 9001, ISO 14001, ISO 45001, VCA) | 1,500 to 3,500 | Safety KPIs and current certificates |
| Secure supplier document portal | 4,000 to 14,000 | Up-to-date certificates, insurance, data sheets |
| Technical copywriting and translation EN NL | 1,500 to 4,500 | Precise technical language |
| Secure hosting, CDN, backups | 1,000 to 3,000 | Fast loading from Houston, Aberdeen or Lagos |
| Testing, training and launch | 1,000 to 3,000 | A team able to update the site itself |
| Total | 15,000 to 46,000 |
These amounts are 2026 ballpark figures excluding VAT. The low end covers 15 pages and a simple password-protected portal. The high end includes 30 to 40 pages, a portal with named buyer accounts, a download log and document expiry alerts.
What buyers at the majors check
Supplier qualification relies on evidence. Each requirement needs a place on the site or in the portal, with a visible update date.
| Buyer requirement | Location | Update frequency |
|---|---|---|
| Valid ISO and VCA certificates | Certification page and portal | At each renewal |
| HSE statistics (TRIR, LTIF, hours worked without incident) | HSE page | Quarterly |
| Anti-bribery policy and code of conduct | Ethics and compliance page | Yearly |
| Sustainability reporting (CSRD data, emissions) | Sustainability page | Yearly |
| Tax and payment behaviour statements | Secure portal | Quarterly |
| Insurance policies (liability, equipment, cargo) | Secure portal | Yearly |
| Project references | References page, with client consent | Twice a year |
European sustainability reporting rules push operators to assess their supply chain: a page quantifying your emissions and safety performance becomes a sales argument in its own right. Be careful with photos: many operators forbid publishing images of their installations without written permission.
A 3 to 5 month plan
The first month covers interviews with management, the HSE manager and the sales lead, followed by the site architecture. Months 2 and 3 are dedicated to design, copywriting and translation, which take longer than development. The document portal is built in parallel and tested with two or three trusted buyers. The final month is for testing, legal review of content and launch. Timelines mostly slip when internal approval involves a head office abroad.
Mini case study
Pieter runs an 80-employee offshore inspection and logistics company in Amsterdam. He invests 28,000 EUR in a bilingual site with a portal. His team answered 6 qualification questionnaires a year at 40 hours each. With the portal, each answer drops to 15 hours: 150 hours saved, valued at 60 EUR an hour, or 9,000 EUR a year.

The real lever lies elsewhere. A yearly inspection contract with an operator is worth about 230,000 EUR with a 15 % margin, or 34,500 EUR. A single extra qualification won thanks to a faster, more complete file pays for the site in the first year. This remains an estimate: a buyer's decision also depends on your prices and track record.
FAQ
Should the site be bilingual from launch?
Yes. Buyers and HSE teams at operators mostly work in English, while local authorities and recruits expect Dutch. Technical translation costs 1,500 to 4,500 EUR, a small budget against the weight of a single tender.
How do we secure the document portal?
Named accounts for each buyer, two-factor authentication, time-limited download links and an access log. These features add 2,500 to 4,500 EUR to the base portal.
Should we publish our HSE statistics?
Aggregated indicators (TRIR, hours worked without incident) reassure buyers, provided they are updated every quarter. An indicator frozen for 18 months has the opposite effect.
What does it cost after launch?
On the market, secure hosting, maintenance and document updates run 250 to 650 EUR a month depending on the expected service level.
Can the site support recruitment too?
Yes, a careers page with job listings and an application form costs 1,500 to 3,000 EUR more. It also helps demonstrate your safety culture to candidates.
