Lifting and Hoisting categorisation flowchart Lifting and Hoisting operations identified to take place
Categories
Categorise and implement control measures as detailed below
Control Measures
Routine 1: Routine lifting and hoisting operations. ➢ Ordinary operations with a crane. ➢ Ordinary operations with portable lifting appliances. ➢ Deck operations with an offshore crane and handling standard CCU’s to and from a supply boat. ➢ Stable load with known and evaluated weight, shape and centre of gravity. ➢ Standard rigging arrangements. ➢ Suitable environmental conditions.
➢ ➢ ➢ ➢
Lifting and Hoisting operation planning. Permit to Work. Risk Assessment (generic). Existing written procedures for these lifting and hoisting operations. ➢ Toolbox talk. ➢ 10 questions for a safe lift.
Non - Routine 2: Simple / basic lifting and hoisting operations ➢ Using only one hoisting appliance. ➢ Stable load with known and evaluated weight, shape and centre of gravity. ➢ Centre of gravity below the hoisting point. ➢ Sufficient working area and ample headroom. ➢ Standard rigging arrangements. ➢ Not within sensitive, difficult or restricted areas.
➢ ➢ ➢ ➢
Lifting and Hoisting operation planning. Permit to Work. Risk Assessment dedicated to the operations. Simple sketch showing operations to be executed, prepared by a competent person. (e.g. signaller/banksman, offshore crane operator or, lifting and hoisting focal point). ➢ Toolbox talk. ➢ 10 questions for a safe lift.
3: Complicated lifting and hoisting operations. ➢ ➢ ➢ ➢ ➢ ➢ ➢ ➢
Using two or more lifting and hoisting appliances. Tandem lift using cranes and tailing of loads. Hoisting of personnel. Hoisting other cargo than standard CCU’s to and from offshore installations and hoisting between two vessels. Operator has no direct view on the load – blind lift. Extended duration, e.g. more than one shifts. Odd shaped loads, not having the centre of gravity in the middle of the load, but with a known weight. Within sensitive, difficult or restricted areas.
4: Complex/Critical lifting and hoisting operations. ➢ Handling of heavy loads (weight of the load > 25 ton). ➢ Weight of load in excess of 90% of the rated capacity of the lifting and hoisting appliance. ➢ Load with unknown, difficult to estimate, weight and or centre of gravity. ➢ Special or expensive load, whose loss would have serious impact on production and operations. ➢ Over active or energised hydrocarbon-containing process equipment. ➢ Hoisting through hatches, small deck openings, in shafts and passing several deck levels. ➢ Hoisting through the splash zone and subsea hoisting. ➢ Non-standard rigging arrangement or equipment.

Lifting and Hoisting operation planning. Permit to Work. Risk Assessment dedicated to the operations. Formal written work package including Method Statement describing the operations. Dedicated and qualified engineering input to Method Statement and “Lift Plan”, by means of numbered drawing(s), clearly and detailed showing all accessories. Preferably: formal approval of work package and planning by a Technical Authority, Subject Matter or Principal Technical Expert (SME, PTE) or independent third party engineers. Toolbox talk. 10 questions for a safe lift.
