How to Calculate Lay-Up Vessel Costs in Indonesia: Hot Lay-Up vs. Cold Lay-Up

Laying up a vessel can help reduce operating expenses when the ship is temporarily out of service. However, the total cost depends on the lay-up method, duration, and location. To calculate lay-up vessel costs in Indonesia, shipowners need to compare hot lay-up and cold lay-up expenses, including crew, maintenance, port charges, compliance, and reactivation costs.

Hot Lay-Up vs. Cold Lay-Up

Hot lay-up keeps essential vessel systems maintained and a reduced crew onboard, allowing the ship to return to service relatively quickly.

Cold lay-up shuts down most machinery and reduces daily operating expenses. However, it requires additional preservation work and more preparation before the vessel can return to service.

Factor	Hot Lay-Up	Cold Lay-Up
Machinery	Essential systems maintained	Most machinery shut down
Duration	Generally shorter periods	Generally longer periods
Crew	Reduced working crew	Minimal approved watchkeeping
Daily costs	Higher	Lower
Preparation costs	Usually lower	Usually higher
Reactivation	Faster	Requires more work

The appropriate option depends on how long the vessel will remain inactive and the total cost of keeping it in lay-up.

Step 1: Choose the Lay-Up Type

Start by estimating the vessel’s expected idle period. Hot lay-up is generally suitable when the vessel may return to service soon. It maintains greater operational readiness, although crew, fuel, and maintenance expenses remain relatively high. Cold lay-up is usually considered for longer periods. Daily expenses are lower, but machinery preservation, inspections, and reactivation can increase the overall cost.

Before deciding, consider:

• Expected lay-up duration
• Vessel condition and maintenance requirements
• Crew and security expenses
• Preparation and reactivation costs
• Lay-up location and available facilities

The lowest daily cost does not always provide the lowest total cost.

Step 2: Identify the Main Costs

Both lay-up methods have recurring expenses, but the amounts differ.

Cost Component	Hot Lay-Up	Cold Lay-Up
Crew	Higher	Lower
Fuel and power	Higher	Lower
Maintenance	Regular maintenance	Preservation and inspections
Security	Required	Required
Port charges	Depends on location	Depends on location
Insurance	Depends on policy	Depends on policy
Reactivation	Generally lower	Generally higher

For vessels in Indonesia, additional expenses may include anchorage or berth charges, agency fees, launch boats, transportation, provisions, security, and technician attendance. Request quotations based on the vessel’s particulars, expected duration, and proposed location.

Step 3: Check Crew and Compliance Requirements

Reducing the crew does not remove the vessel’s safety and regulatory responsibilities. Before entering lay-up, the owner or manager should coordinate with the relevant parties.

Flag state
Confirm the permitted manning level, watchkeeping arrangements, and any required approvals.

Classification society
Review maintenance requirements, lay-up status, survey schedules, and reactivation procedures.

Insurance provider
Confirm whether the lay-up arrangement affects insurance coverage, premiums, or notification requirements.

Port authorities
Verify permission to use the proposed anchorage or berth and confirm the applicable local procedures.

Safety and environmental requirements
Maintain appropriate fire protection, security, emergency arrangements, and pollution prevention measures.

Requirements may differ depending on the vessel, lay-up duration, and Indonesian port.

Step 4: Calculate the Total Lay-Up Cost

To compare both options, use the same calculation.

Total Lay-Up Cost = (Daily Cost × Number of Days) + Preparation Cost + Reactivation Cost

Example Calculation
Assume a vessel normally costs USD 10,000 per day to operate.
Using illustrative percentages from a historical DNV GL lay-up cost model:

• Hot lay-up: 74% of normal operating costs = USD 7,400/day
• Cold lay-up: 34% of normal operating costs = USD 3,400/day
• Additional cold lay-up preparation and reactivation costs: USD 600,000

Lay-Up Duration	Hot Lay-Up	Cold Lay-Up	Lower Cost
90 days	USD 666,000	USD 906,000	Hot
150 days	USD 1,110,000	USD 1,110,000	Equal
300 days	USD 2,220,000	USD 1,620,000	Cold

These figures are hypothetical examples based on historical cost assumptions, not actual Indonesian port rates. The example assumes that other one-time costs are equal.

Find the Break-Even Point
The break-even point shows when cold lay-up becomes more economical.

Break-Even Days = Additional Cold Lay-Up Costs ÷ Daily Savings

Using the example:
USD 600,000 ÷ (USD 7,400 − USD 3,400) = 150 days

In this scenario, cold lay-up becomes cheaper after 150 days. Actual results depend on the vessel’s operating expenses, lay-up location, preservation requirements, and reactivation costs.

Step 5: Consider the Lay-Up Location

The lay-up location can significantly affect the final budget. In Indonesia, locations such as Batam, the Riau Islands, Balikpapan, and Surabaya may be considered depending on vessel requirements and local availability.
Before selecting a location, check:

• Anchorage or berth availability and permission
• Port charges
• Water depth and weather conditions
• Security and watchkeeping arrangements
• Access to technicians and spare parts
• Transportation and launch boat services

A lower anchorage fee does not always mean a lower total cost. Additional transportation, security, and maintenance expenses can affect the final amount. Evaluating anchorage fees alone is rarely enough to predict your total expenditures; local port tariffs, security arrangements, and environmental compliance rules across different sectors of Indonesian waters play a major role in the overall budget.

Step 6: Include Reactivation Costs

Reactivation should be included in the budget before the vessel enters lay-up. A vessel returning from hot lay-up generally requires less preparation because essential systems have remained maintained.
Cold lay-up may require additional work, including:

• Machinery recommissioning
• Equipment testing
• Crew mobilization
• Technical inspections and surveys
• Repairs identified during reactivation

These expenses can reduce the savings achieved during the lay-up period. The final decision should consider both the cost of keeping the vessel inactive and the cost of returning it to service.
