4. Confusion About What Is Layup
Type of Layup/ Layover
Hot (full crew)
Warm (minimum manning)
Cold (no crew)
Preparing for Layup/ Layover
Maintenance routines required
Preparing machinery for layup
Equipment removal for storage
Humidity issues
Reactivation Time
Equipment failure
Deterioration
Pressure to be ready in case of new work comes up.
Cost of Services
Best Layup Location & Where
Port
Anchorage
Security
Quality of Service
Services Being Offered
Do nothing
Traditional service may not meet my needs
VCI & Enhanced Layup Services
Fleet Layup Strategies

5. Concerns With Laid Up Vessels Who Use Cheap Operators
No emergency response procedures written for cold layup
Fire, Flooding, Collision, Unauthorised Boarding, Medical Emergency, Severe Weather
No procedures displayed for watchmen & staff to follow
Not duplicating full set of bilge alarms
Not removing flammables from the vessel
Not removing combustibles from the vessels
Breaking toilet seals with closed sewerage tanks. What’s in the tank?
Sea water systems shut down full of sea water.
Lack of understanding about the use and capability of dehumidifiers. Well undersized and spaces not sealed

6. Understanding the Layup Process
Reliability, cost and time increases to reactivate the vessel if the deactivation and layup are not managed properly
The importance of a proper reactivation plan cannot be underestimated but I never saw one made by the clients!

7. Vessel Pre Arrival Layup Issues
Anchor chain wear greater than class maximum wear requirements. Older vessels especially and slippage occurs on anchor chain during lowering and heaving
Boilers are not soot blown prior to arrival and boiler heavily fouled
Fuel lines not changed over from HFO 4 hour’s minimum to arrival. Dirty fuel systems
Defective equipment not logged as out of service or defective. Causes hand over disputes when the client comes for the vessel.

8. During Deactivation
Generally crew and management can have low understanding to recommendations and best practises for layup
Leaving sea water lines full cause corrosion and flooding issues
Bilges full and bilge holding tank is full
Flammables not removed during layup
Computer not backed up or removed from the vessel causing loss of data
Crew leave ship early and work does not get done
Not created a reactivation plan
Resources
Materials
Time to complete

9. Traditional Vessel In Layup Issues
Incorrect or no maintenance being done
Equipment not being turned regularly and seizing
Equipment lube oil pumps being started routinely and causing surface corrosion & pitting
Hydraulic rams such as steering gear rams ungreased and pitting occurs
Deck equipment not turned or operated causing seizure of equipment
Rollers & fairleads
Lifeboat davit arms becoming stiff and not operating
Deck valves turned causing seizure
Wires not coated on drums and covered causing rust on the wire
Relying on out of survey equipment
Extinguishers
life raft’s
Crane for lifting equipment
Gangway wire
Failure is visible

10. Traditional Vessel In Layup Issues- Continued
Corrosion of pressurised ballast sea water pipes causing flooding- Quite common in tanker pump rooms but also when scuppers pass through ballast tanks.
Pest Infestation and dry food stores left open
Toilets not covered and water evaporates causing loss of seal direct to the sewerage tank
Using emergency generator for power and generator fails. Not rated for additional usage and not able to power the crane to get a rental generator on board. Require to reactivate the main generator and flood sea water system.

11. Traditional Vessel Reactivation Issues
Start to see the hidden failure modes
Electronic equipment failure. Failed to start up
Pneumatic control systems sticky or not operating correctly
Boiler combustion control systems require recalibration
Stiffening of ship side valves and cannot open
Corrosion issues in ballast lines
Spares required to reactivate not on board or removed and not logged
Crew not familiar with the vessel or been away from it a long time.
No plan and therefore no idea how long to reactivate.
Could not pick up the anchor. Twists in the chain

12. Factors to Consider For Reactivation
When do I expect to return my vessel/s to service?
Am I managing a fleet of laid up vessels?
What is the reactivation time?
Is the vessel due for dry dock prior to reactivation?
Do I know where the vessel is likely to re-enter service next?
Is there a reactivation plan?
Has any failure analysis studies been completed for the vessel?
What layup strategy & maintenance was done in layup?
Was the vessel deactivated properly?
