risk analysis and risk assessment on all aspects of the operation; formulate
corresponding safety precautions; carry out technical disclosure on construction plan
and safety to the relevant workers.
3.5.2 The lifting operation commander, crane driver, rigger shall be familiar with the
lifting plan and strictly follow the lifting plan.
3.6 Filing
3.6.1 Before lifting, according to regulations, an application for crane vessel registration
shall be made to the relevant departments of the Offshore Petroleum Operation Safety
Office of the State Administration of Work Safety.
vessel shall meet the safe operation requirements of the crane and be recorded.
b) Review the anchor points and keep records.
c) The anchor cables (chains) of the front and rear windlasses are evenly stressed.
d) The status and capabilities of the load regulating system and backup load
regulating pump are normal.
e) The vessel's main engine, power supply system, control system are normal.
6.2 Crane inspection
After the crane vessel is in position, the crane shall be inspected but not limited to the
following:
a) The crane braking device, transmission device, pulley block, control system are
normal.
b) The hook height limiter and boom limiter are normal.
c) The lifting span indicator and lifting weight indicator are normal.
d) All operating handles, buttons, signals and alarm devices, communication
equipment in the crane operating cab are normal.
e) The boom, crane vessel deck and operating site lighting shall meet the operating
requirements.
6.3 Inspection of lifted objects
After the crane vessel is in position, the lifted objects shall be inspected but not limited
to the following:
a) The lifting points of the lifted object, snap rings, rigging, struts, towing system
rigging, barge deck, strength and stability analysis of piers, etc. shall meet safety
technical requirements.
b) The specifications and models of rigging and snap rings shall be consistent with
the lifting design plan.
c) Rigging and snap rings shall be inspected by professional inspection agencies.
7 Lifting operations
7.1 Situations where lifting is prohibited
Lifting operations shall not be carried out under any of the following circumstances:
a) The weight of the lifted object exceeds the rated load of the crane or the weight is
unclear.
b) The fixtures of the lifted objects are not completely released.
c) The crane brake or safety device fails, the hook nut anti-loosening device is
damaged, the wire rope is damaged to the point of being scrapped.
d) There is no padding between the edges and corners of the lifted object and the
wire rope.
e) The longitudinal and transverse angles of the ship are greater than the vessel's
stability requirements.
f) Poor visibility makes it impossible to clearly see the vessel’s deck, lifted objects
and command signals.
g) The wave height and sea conditions in the operating sea area do not meet the
requirements for safe operation of crane vessels.
h) The wind force in the operating sea area is greater than level 6 (including level 6).
