Why the Cheapest Drydock Quote Is Almost Always the Most Expensive

The quote that looks like a bargain
Say you've got a drydock quote sitting in front of you at $168,000. Another one comes in at $204,000. The spec sheets look roughly comparable. Most owners do the arithmetic and sign the first one — that's nearly forty grand in your pocket, what's there to think about?
Six months later, that saving tends to be gone. Sometimes not just gone, but negative.
I'm a quality and compliance manager at Damen Shipyards Group. Four years in this seat, and my job is to review every drydock spec and every repair report that comes through our yards — roughly 180 of them in a given year. In 2024, I rejected 21% of first-pass deliverables because of out-of-tolerance weld measurements and missing NDT records. "Rejected" isn't an abstract word in that sentence. It means the vessel is still in our dock and every schedule downstream is now somebody's problem.
I'm not saying the cheaper quote is always the wrong one. What I'm saying is that the lower number is usually lower because its scope is narrower. And the parts that got trimmed rarely show up on the page in front of you.
What's actually missing from that bid
Every drydock quote rests on a set of assumptions about scope. Cheap quotes often don't write those assumptions down.
Take surface prep. A cheap quote says "high-pressure wash." A more expensive one says "surface preparation to Sa 2.5." Those are not the same job. One is knocking the loose stuff off; the other is reaching the roughness profile a coating spec actually requires. When the paint starts blistering in a cargo hold ten months down the line, the second quote's price tag starts to make sense retroactively.
Same thing happens with the phrase "class compliant." Every yard will write it into a quote. Very few quote documents specify what NDT coverage that actually means, at what stage the inspections get performed, or whether an independent surveyor or the yard's own team is doing the measuring. Classification societies like DNV and ABS have requirements on the books. But "compliant" can be translated into very different sums of money once the steel's already been assembled — and nobody's comparing those sums when the bids first come in.
There's also a piece almost no one volunteers: dock time itself costs money. A vessel's drydock slot is a fixed window. If the surface prep runs two days longer than planned and those two days weren't built into the yard's schedule, the owner is paying in time, not in cash. A medium-sized vessel's charter equivalent can run into tens of thousands of dollars per day. That figure doesn't appear on the quote. It never does. But it's real, and it's usually the biggest line item in the whole comparison.
What the real bill looks like
In 2023, we took in a vessel that had come out of a "value" drydock nine months earlier. The hull coating had already started to fail — blistering in spots, some localized delamination. The previous yard had done what its contract said. The issue was everything the contract didn't say.
Rework costs aren't just new paint. It's re-scheduling dock time, coordinating transport, sourcing the coating system again, re-doing inspection records, and absorbing the disruption to the vessel's charter schedule. When we tallied it up, the all-in came to just north of two hundred thousand. The owner thought they'd saved about forty. They spent five times that replacing the saving.
I've run the same math enough times now that I think of it as a pattern rather than an anecdote. It took about three years and somewhere in the neighborhood of five hundred specs before I fully internalized it: the gap between the bid price and the actual cost almost never comes from a yard cutting corners on purpose. It comes from scope that wasn't written down. The cheap quote didn't lie to you. It just answered a narrower question.
Three questions I'd ask before signing anything
I don't review drydock quotes the same way I did a few years back, and I've been slowly pushing this framework onto the owners I work with during pre-job meetings. It's not complicated. Three questions. Force the supplier to write the answers into the document.
- What does the scope actually cover? Surface prep standard, NDT coverage percentage, coating system spec, inspection hold points — all of it belongs in the quote. "Class compliant" on its own isn't a complete answer, because different yards interpret compliant differently. Require the spec sheet to attach those numbers before the bid gets compared.
- Who eats the delay? Drydock time has a fixed cost. Put a day rate on it, define what counts as weather-down days versus yard-caused delay, and write the change-order threshold into the contract. Once both sides have put a number on lost time, the estimates get noticeably more honest. Nobody wants to eat a day rate they agreed to.
- What does year three look like? Coating life expectancy, weld repair probabilities, class condition items — all of that belongs in the comparison. A yard that saves on the coating system because its quote looked leaner often comes back with a full coating renewal that erases the saving and then some. Rolling those three-year costs into a per-vessel-per-year figure is the only way to get a realistic comparison.
That's the TCO logic in a nutshell — the sticker price is one input into a longer equation. About three years ago we started requiring a mandatory scope definition document attached to every drydock inquiry. The first few months, suppliers grumbled. Since then, our variation orders caused by "scope wasn't clear" have dropped meaningfully. Turns out putting the fine print on the front page saves a lot of arguing later.
Bottom line
Here's the thing: the lowest drydock quote is a one-day commitment. It doesn't tell you what day 30, day 300, or day 1,100 will cost. Run those days through the math, and the "expensive" quote turns out to be the cheap one more often than not. Not every time. But most times.
Next time you're comparing bids, try this — write the scope down at the inquiry stage, put delay rates in the contract, and roll the three-year cost estimate into the comparison. The extra day-one cash you spend buying down uncertainty tends to come back with interest when the vessel leaves the dock on schedule and stays out of it for the next three years.
