Damen Quality Assurance: 7 FAQs About Choosing the Right Shipyard Partner

What should I look for when evaluating a shipyard's quality?

Look, I'm not saying you should ignore certifications. Every inspector will tell you to check ISO 9001, welding procedures, and material traceability. But here's the thing: those are baseline requirements, not differentiators. What I've found over the past four years of reviewing roughly 200+ vessel deliveries for Damen is that the real signal is in how a shipyard handles deviations.

When I ask a potential yard "What's your process when a weld fails NDT?", the ones who have a clear, documented rework procedure with root cause analysis — not just a quick grind-and-fix — are the ones that deliver consistent quality. The others? They'll tell you it "never happens." That's a red flag. In my experience, it always happens on some level. The question is how they deal with it.

Why do some shipyards offer significantly lower prices than others?

I've rejected roughly 15% of first deliveries in 2024 due to specs being off — wrong plate thickness, improper coating, missing documentation. And in almost every case, the root cause traced back to a price-driven decision upstream.

One example: we received a batch of fairing kits for an offshore platform where the corrosion allowance was visibly thinner than our spec. The vendor claimed it was "within industry standard." Normal tolerance is ±0.2 mm. We rejected the batch, and they redid it at their cost. But the schedule slip cost us $22,000 in re-planning and site idle time.

The lower price came from cutting one spec — a spec we didn't catch in the initial quote because it was buried in the fine print. So my rule of thumb: if the price is more than 20% below comparable bids, ask hard questions about what's being sacrificed. I'm not 100% sure every low bid hides a problem, but in my experience, the correlation is strong.

How do you ensure specifications are met during construction?

Let me tell you about a mistake I made early in my career. I assumed that if a shipyard submitted an approved inspection plan, they'd follow it. Didn't verify. Turned out their interpretation of "witness hold points" was different from ours — they only called us for critical inspections, not the intermediate checks.

Learned never to assume alignment after that. Now every contract includes a detailed Inspection and Test Plan (ITP) with specific hold points, notification windows, and documentation required. And we send a Damen quality representative for random spot checks — not every inspection, but enough to keep the yard honest. That simple change increased on-spec compliance from 78% to 94% in the following year.

What are the hidden costs of choosing the cheapest option?

Here's the math I run every time a procurement team pushes for the lowest quote. Let's say you save $200,000 on a $2 million repair contract. Sounds good. But if that savings means the job takes two weeks longer because the yard doesn't have the right equipment, your offshore crew stays idle — that's maybe $50,000 per day in lost production. Two weeks = $700,000. Suddenly that "savings" is a $500,000 loss.

And that's assuming no rework. I've seen a $150,000 paint job fail after six months because the yard used a cheaper epoxy that wasn't suitable for the operating temperature. The re-coating cost $220,000 plus de-mobilization. The original savings were $15,000 on material. You do the math.

So I always say: look at total cost of ownership, not sticker price. Setup fees, expedite charges, rework probability, schedule risk — they all add up. In my experience managing over 50 projects in the last five years, the cheapest initial quote cost us more in 60% of cases.

How does Damen's modular design approach affect quality?

This is one of those things I didn't appreciate until I saw it in action. Damen's modular approach means components — like engine rooms, accommodation blocks, and cargo handling systems — are built in parallel under controlled factory conditions, not exposed to weather on a building berth.

What that translates to is consistency. We can measure and document each module's quality before integration. For a recent 50-meter workboat project, we had 12 modules built simultaneously. Each had its own ITP, and we caught three minor issues before they ever entered the dry dock.

Compare that to traditional stick-built construction where welding is done in situ, rain delays are common, and accessing a defective weld in a completed hull costs ten times more to fix. So the modular approach isn't just faster — it's inherently higher quality because you can inspect and correct at the component level.

What happens when a quality issue is discovered after delivery?

I hit 'accept' on a delivery once and immediately wondered: "Did I miss something?" The two weeks until the first sea trial were stressful. Turned out the hydraulic pump alignment was borderline — not enough to fail sea trials, but enough to cause premature wear.

Here's what we do at Damen: every vessel has a 12-month warranty period covering defects from workmanship and materials. But more importantly, we log all post-delivery issues into a quality database and review them quarterly. That data feeds back into our production standards. When we saw a pattern of pump alignment issues in 2023, we updated our alignment procedure and added a laser-check step. Defects dropped by 70% in 2024.

The point is: even with the best processes, issues can slip through. What separates a good shipyard from a great one is how they use those slip-ups to get better. If a yard tells you they never have post-delivery problems, they're either not inspecting closely enough or they're not being honest.

How can I verify a shipyard's claims about their capabilities?

Don't take their word for it. Ask for: (1) a list of three recent projects of similar scope, (2) contact information for the client's project manager (not sales), and (3) permission to visit an active project site unannounced.

I've done this myself — showed up at a yard claiming they could handle API-level fabrication. The workshop was clean, welders were qualified, but their NDT equipment was outdated. That told me more than any brochure or sales presentation ever could.

Also, check for third-party certifications from class societies like DNV, ABS, or Lloyd's. Those audits are rigorous and public. If a yard has a pending or recent non-conformance report, that's valuable intelligence. Between you and me, I've saved my company from two costly partnerships just by doing a quick class society database check.
