Hot Layup
What Is Hot Lay-Up?
Hot lay-up is the preferred option for vessel owners who need the flexibility to return their vessel to active service at short notice. During hot lay-up, a reduced skeleton crew remains onboard, essential machinery is kept running, and the vessel is maintained in a ready-to-operate condition.
While hot lay-up carries higher ongoing costs than cold lay-up, it significantly reduces crewing, insurance, and operating expenditure compared to full trading status — making it the ideal solution for market downturns expected to last weeks to months, or for vessels awaiting a confirmed next charter.
At International Shipcare, every hot lay-up programme is managed by a dedicated Technical Superintendent and supported by our 24/7 communications centre at Brunei Bay — the world’s first officially gazetted lay-up anchorage.
Hot Lay-Up vs Running Costs
Cost Category | Normal Running (100%) | Hot Lay-Up | Cold Lay-Up |
H&M Insurance | 100% | 100% | 70% |
P&I Insurance | 100% | 50% | 10% |
Crewing | 100% | 70% | 0% |
Repair & Maintenance | 100% | 50% | 0% |
Spares & Consumables | 100% | 33% | 0% |
Auxiliary Fuel | 100% | 50% | 5% |
Hot lay-up delivers meaningful savings across P&I insurance, crewing, repair, maintenance, and fuel — while keeping the vessel ready for rapid return to service.
Hot Lay-Up Procedure
Step 1: Initial Consultation & Lay-Up Planning
ISC’s Technical Superintendent meets with the vessel’s management team to assess the vessel type, anticipated idle duration, flag state requirements, and owner priorities. A customised hot lay-up plan is developed covering crew reduction targets, machinery maintenance schedules, and inspection frequencies aligned with Classification Society requirements.
Step 2: Crew Reduction & Safe Manning
Manning is reduced to the minimum permitted under the vessel’s Safe Manning Certificate, as approved by the Flag State. ISC advises on the optimal crew composition to maintain vessel safety and Class compliance while minimising ongoing crewing costs.
Step 3: Machinery Preservation & Operational Maintenance
Essential machinery — main engine, generators, pumps, and navigation systems — is kept operational in the most economical manner, in consultation with ISC’s technical team. Where machinery is placed on reduced-frequency run cycles, ISC documents the schedule and monitors compliance to prevent deterioration.
Step 4: Dehumidification of Enclosed Spaces
Although the vessel remains active, enclosed machinery spaces and accommodation areas are susceptible to humidity-driven corrosion during extended idle periods in tropical climates. ISC deploys dehumidification (DH) equipment for critical enclosed spaces to prevent moisture ingress and protect electrical systems and equipment.
Step 5: Ongoing Inspection & Monitoring
ISC conducts scheduled onboard inspections on a weekly and monthly basis. All activities are logged and reported to owners and managers. Our 24/7 communications centre maintains 4-hourly radio check-ins with every vessel at anchorage.

When to Choose Hot Lay-Up vs Cold Lay-Up
Hot lay-up is the right choice when:
- The vessel is expected to be idle for less than 6 months
- A fast return to service (days, not weeks) is required
- The vessel is awaiting a confirmed next charter or voyage order
- The owner wishes to retain a reduced crew onboard for security or maintenance continuity
Cold lay-up is the better option when:
- The vessel will be idle for 12 months or more
- Maximum cost reduction is the priority
- Reactivation within 14 days is acceptable
For vessels falling between these two scenarios, ISC also offers Tailor-Made Lay-Up Plans built around your specific vessel and timeline.
Frequently Asked Questions — Hot Lay-Up
skeleton crew onboard and maintains essential machinery in operational condition, allowing fast reactivation. Cold lay-up fully decommissions the vessel — crew signs off entirely and all major machinery is shut down — making it more cost-effective for long idle periods but requiring more lead time (up to 14 days) to return to service.
A vessel in hot lay-up can typically be reactivated immediately, subject to the availability of a full crew complement, since machinery remains operational. This makes hot lay-up ideal for vessels expecting confirmed employment within weeks or a few months.
Yes. ISC has managed hot lay-up programmes for bulk carriers, container ships, LNG carriers, FPSOs, and anchor handling tugs. Our customised plans are adapted to the specific systems and classification requirements of each vessel type.
