I Almost Picked a $152,000 Shipyard Quote Over Damen—The TCO Model Changed My Decision

It Started with a Number I Wanted to Believe

In June 2024, I sat in our Den Helder office with nine shipyard proposals for one 32-metre survey vessel on the table. The five-year special survey was due before the end of the year, and the finance director had told me to cut 6% from next year’s maintenance budget. The quote that kept pulling my attention was not from Damen. It was a regional yard’s number: $152,000. Damen’s proposal was $241,500.

I won’t pretend I didn’t feel the pull. I’ve been procurement manager at an offshore survey and subsea services company for six years, managing about $1.2 million in vessel repair and dry-docking spend every year. That budget is not large enough to attract special attention, but it is large enough to hurt when a docking runs over. By that point, I had negotiated with more than 20 shipyards and documented every order in our cost tracking system. I knew the textbook answer: compare total cost of ownership, not the headline number. The problem is that the textbook answer becomes harder to explain after a finance director has seen a nine-line quote at $152,000.

My colleague Henry, who tracks dry-dock stats across our small fleet, walked into my office and said, “Just remember why we added the schedule-risk column to the scoring sheet.” He wasn’t telling me to choose Damen. He was telling me not to let one number make the decision for me.

That warning came from experience. Four years earlier, I had approved a bid that was $38,000 lower than the next realistic option. By the time the yard finished fixing what the surveyor found, the final invoice was $51,000 above that same next option. That mistake is why I built the cost calculator in the first place.

Still, I was hungry for a cheaper number. The regional yard had done acceptable work for us in 2022. Their quote listed the same class survey items, the same coating touch-up areas, the same shaft and rudder inspections. On paper, the two scopes looked identical.

Then I Compared What Damen Actually Included

The difference started on the second page. The lower proposal said the price covered the work “as per attached scope” and excluded:

• dock and berth costs after the first four days, at $4,800 per day;
• waste disposal, tank cleaning and sludge handling outside the specified tanks;
• surveyor attendance after the first day;
• all discovered steelwork repairs, to be quoted after inspection; and
• project management and reporting if the vessel remained in the yard longer than seven days.

Damen’s quote, from Damen Shiprepair Harlingen, had a different tone. It split the five-year survey into a fixed-price package, listed the norm times for each inspection opening, confirmed a start date in the dock calendar, and priced expected extra work using a rate card attached behind the main estimate. It also included a day-by-day schedule from arrival to redelivery.

The low quote wasn’t dishonest. It was a starting point. Damen’s quote was closer to a finish line.

When I added the most likely extras from our previous dry-dockings, the gap between the two proposals shrank from $89,500 to roughly $17,000. When I added the cost of a one-week schedule delay—using Henry’s stats on planned versus actual redelivery dates—Damen became the cheaper choice.

Actually, that understates it. What mattered was not which yard had the lower starting number, but which proposal was closest to the invoice we would actually pay. In our experience, Damen’s documentation matched the final bill more closely than most. You pay for that transparency in the base price.

I don’t have hard data on industry-wide overruns. I can tell you what our own records show: two of our last three “budget” dry-dockings produced change orders above the original contract value, while the Damen jobs we had used before stayed near the rate card. That sample is too small for a statistical conclusion, but it is big enough to influence my procedure.

What Happened When We Docked at Damen in November

We selected Damen for the third week of November 2024. The dry-docking at Harlingen took 18 days, including two days of propeller pitting repair that only became visible after the shaft was pulled. The final invoice was about 2.1% above the proposal. The vessel went back into service on 6 December and made the winter survey campaign without unscheduled dock time.

Had we taken the lower quote, that result would still have been possible. I don’t want to imply otherwise. The difference is that with Damen, we had a confirmed schedule, a fixed price for the survey package, and a rate card for the unknowns. The cheaper option had no rate card and no confirmed start date in the dock calendar. It offered a duration, but not a slot.

When I Would Still Choose Someone Else

To be fair, Damen is not the right call for every repair. If the scope is simple, our own superintendent can supervise it, and a short delay won’t hurt, I will happily use a smaller yard and keep more money in the maintenance budget. Last year, I approved a $16,000 bow-thruster repair at a local yard because the job was standard, the vessel could be spared for two weeks, and there was no class deadline. It would have been wasteful to pay for Damen’s planning overhead on a routine repair. That is not a criticism of Damen; it is honest suitability.

So when do I choose Damen? When the cost of being late is high. When the vessel has a confirmed contract or survey window. When the inspection scope hides unknowns below the waterline. When the yard’s planning system is part of my risk mitigation. In those cases, the relevant question is not “Can we save $80,000?” It is “What is the probability that a cheaper proposal still leaves us operational on the agreed date?”

Three Lessons I Took From That Comparison

First, make every yard quote the same complete scope. If a vendor says exclusions are in the general terms, treat that as a red flag and price those terms before comparing totals.

Second, put a schedule risk number on the spreadsheet. If the vessel earns $9,000 per day, a one-week delay is a cost. Leave it out and you are not comparing shipyards; you are comparing arithmetic.

Third, be honest about when cheap enough is actually good enough. Damen does not need to be the low-cost option for every maintenance task. For critical, schedule-sensitive repair work, however, paying for certainty can be the least expensive thing you do.

These numbers came from proposals received in June 2024. Build your comparison on your own quotes, because steel prices, dock capacity and season all move the starting point. The method matters more than the figure.

That is the part that does not show up in a vendor’s first paragraph. The real value of a Damen quote is not a smaller number; it is a narrower gap between the number and the final invoice. After six years of tracking dry-docking costs, I trust a yard that treats its price as a promise. In this industry, a promise with a schedule is often the cheapest thing you can buy.
