The third and last scenario arises when the vessel is unemployed at the time of the repairs, either due to not having been fixed for employment at the time the casualty occurred or due to a cancellation of the employment because of the casualty. A similar situation arises if the repairs are deferred until after the vessel has completed performance of any existing charter.
The loss of time must be calculated only to the extent that the vessel actually lost income. If the vessel would have been unserviceable regardless of the damage and related repairs (e.g. if the vessel would have been laid up in any event), the assured will have no claim under his loss of hire insurance, see the comments in 3.1 above.
