Drydock — Capitalization of Scheduled Maintenance Under Component Approach
Capitalizing drydock costs as a vessel component — replacing the previously depreciated drydock component with the new drydock expenditure, which is then depreciated over the next drydock cycle.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Vessel — Drydock Component (New Drydock Costs Capitalized) | Asset (+) | 4,850,000.00 | - |
| Vessel — Previous Drydock Component (Remaining Book Value Written Off) | Asset (-) | - | 850,000.00 |
| Loss on Derecognition — Previous Drydock Component | Expense (+) | 850,000.00 | - |
| Accounts Payable / Cash (Shipyard Invoice + Materials + Services) | Liability (+) / Asset (-) | - | 4,850,000.00 |
💡 Accountant's Note
Drydocking is the mandatory periodic haul-out of a vessel for underwater hull inspection, maintenance, and class society certification renewal — required every 2.5–5 years (most vessels operate on 5-year class cycles with an intermediate survey at 2.5 years). Drydock costs include: shipyard steel repair, hull painting (anti-fouling paint), propeller polishing, sea chest cleaning, tailshaft withdrawal and inspection, rudder overhaul, thruster maintenance, anchor chain inspection and replacement, accommodation upgrades, and classification society fees. Under the COMPONENT APPROACH (IAS 16.43 / ASC 360): drydock costs are CAPITALIZED as a new vessel component — not expensed as incurred. The previous drydock component (fully or partially depreciated) is DERECOGNIZED at the commencement of the new drydock. This prevents 'double-counting' future depreciation. The new drydock component is depreciated straight-line over the next drydock cycle (5 years). This is a critical distinction from the 'defer and amortize' method historically used — that method is no longer permitted under IFRS.
Practitioner & Systems Framework
💻 ERP Architecture
Drydock project management requires a dedicated cost code: all shipyard invoices, materials, crew overtime during drydock, superintendent fees, and classification society fees are coded to the drydock project. The total project cost becomes the new drydock component in the fixed asset register. The old drydock component's net book value must be determined at the start of the drydock — this requires the depreciation schedule to be current. Vessel components should be reviewed at each drydock to assess whether the component approach accurately reflects the remaining lives of all parts.
⚠️ Audit Flags
Drydock capitalization is a frequent audit area — the temptation to expense drydock costs (increasing current-period costs but avoiding future depreciation) or to capitalize items that should be expensed (e.g., routine crew costs during drydock, painting that is maintenance not improvement). Auditors test: (1) Appropriate items capitalized vs. expensed — only costs that are part of the drydock cycle (not voyage repairs, routine maintenance) are capitalizable. (2) Previous drydock component derecognition — is the remaining book value of the old component written off? (3) New drydock component depreciation period — is it calibrated to the next scheduled drydock (5 years for most vessels)?
📄 Required Documentation
Drydock project cost summary (by cost category: steel, painting, inspection, equipment overhaul), shipyard contract and invoices, classification society certificates issued after drydock (confirming class renewal), previous drydock component book value at derecognition, new drydock component addition to asset register, depreciation schedule (new component), and off-hire analysis during drydock period.
