Dry-Dock Financing: Drydocking Costs and Structure

A dry-dock period is a recurring, planned, and costly item in the life of every classed vessel. Underwater hull inspection, paint renewal, and required repairs all happen in this window. This guide explains the cost components of a dry-dock, yard selection, and how to finance the period.

What a dry-dock is and why it costs

A dry-dock is the period when the vessel is lifted out of the water and the full hull becomes accessible. Class rules require most commercial ships to dry-dock every 2.5-5 years. Cost falls into three main headings:

Dock fee: The yard's daily dock hire and service charge
Work items: Paint, anti-fouling, steel repair, valve and shaft work
Indirect cost: Revenue lost while the vessel is out of service

That third item is usually underestimated; for a charter operator, dock time is direct lost revenue.

Cost drivers

| Driver | Effect | |---|---| | Vessel length / tonnage | Sets the dock fee and work volume | | Hull condition | Corrosion and steel renewal raise cost | | Paint system | Premium anti-fouling costs more but lasts longer | | Yard location | A positioning voyage adds cost | | Scope of work | Class only, or refit combined as well |

A well-planned dry-dock minimises surprise steel work by nailing down scope in advance.

Timing around the class window

A dry-dock period is not arbitrary; it tracks the class calendar. Most structures bring the dry-dock into the same window as the special survey — so the vessel completes both class renewal and hull work in one haul-out. This combination shortens out-of-service time and improves capital efficiency.

A typical planning horizon:

12 months out: Class window fixed, preliminary scope drawn
6-9 months out: Yard quotes obtained, booking made
3-6 months out: Financing structure arranged
Dock period: 2-8 weeks depending on scope
After: Class approval, insurance renewal, return to service

Yard selection

Choosing a yard is not only a price question. It also matters on the financing side:

Track record: Yards with a refit-yard history are seen as more reliable
Capacity: The right-sized dock and a workable booking window
Location: A yard near the vessel's route lowers positioning cost
Payment plan: Some yards offer extended payment terms

Capable yards book out months ahead; leaving the booking late both raises the price and compresses the schedule.

Structures to finance a dry-dock period

1. Short-term investment loan

For the full dock and work cost. Interest-only during the work, principal installments once operations resume. This is the most common structure.

2. Top-up of existing credit

Added to the operator's existing investment loan. Minimal extra negotiation, easy to manage.

3. Yard financing

Some yards offer their own extended payment plan. It looks attractive, but an effective-cost comparison is essential.

4. Fleet maintenance reserve

For operators with several vessels, the annual dock calendar ties into a single financing flow.

A dry-dock is usually a short-to-medium-term item; unlike purchase financing, the tenor is work-tied and the output is clear. For wider context, see the refit and class definitions.

The grace-period logic

During a dry-dock the vessel earns nothing. A well-built structure provides a grace period (repayment deferral) for the duration of the work. Principal repayment kicks in only after operations restart. This softens the double burden on cash flow — revenue stopping plus spending.

Frequently asked questions

Should I combine the dry-dock with class renewal?

Usually yes. Bringing both into one dock window shortens out-of-service time and lowers total cost. Most financing structures also prefer this combined scope.

Which is more expensive — the dock fee or the work items?

It depends on the vessel. On older or corroded hulls, steel and paint work can exceed the dock fee. On younger vessels, dock hire and routine items dominate.

Do I need a firm cost for financing?

An approved yard quote speeds the financing conversation. For items that only become clear once opened up — like steel work — adding a contingency to the structure is common.

How long does a dry-dock take?

2-8 weeks depending on scope. A class-only check is short, while projects combined with a refit stretch across weeks.
