Night Time Operations
With the following controls in place it may be allowable for personnel transfers using the FROG
Personnel Transfer Capsule to take place during the hours of darkness:
i.
The risk assessment for the task shall be comprehensively reviewed prior to commencing
operations. The lifting plan and risk assessment shall be approved in writing by the Offshore
Installation Manager or appointed deputy.
ii.
The operator should have contingency to immediately rescue the passengers from the water
e.g. Fast Rescue Craft. Without fast rescue contingency personnel transfers should not take
place.
iii.
The crane boom should be fitted with adequate floodlights to illuminate the crane hook and
FROG unit. The Crane Operator must maintain a clear line of view with the FROG unit at all
times.
iv.
The take-off and landing areas should be illuminated to a level of at least 20 lux or greater.
v.
The FROG unit should be fitted with a strobe light to allow clear locating by all parties.
vi.
The hoisting, transit and landing paths of the FROG unit should be predefined in the lifting
plan and are adhered to.
vii.
Radio contact should be maintained throughout the entire lifting operation between the
Crane Operator and the take-off and landing site.
viii.
An unmanned trial run which covers, as a minimum, the take-off, transit and landing paths
of the FROG should be conducted prior to commencing personnel transfers. The Crane
Operator should confirm readiness to proceed on completion of the trial run.
ix.
A non-visual based method of communicating with the lifted personnel should be in place,
e.g. radio or loudhailer, in the event of an emergency.
