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
a) The crane braking device, transmission device, pulley block, control system are
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
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

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).
i) The tension of the crane vessel’s positioning anchor cannot meet the requirements
for stable vessel position.
7.2 Preparation for lifting
Lifting preparation includes but is not limited to the following:
a) Before lifting operations, a test lifting operation shall be carried out to ensure that
