2 History Established in Water Weights was the originator of the water-filled load bag, used in proof load testing of cranes and lifting equipment.

3 What are Water Weights? Water Weights proof load test bags are used for suspended or deck loads using any number of bags for loads up to 1500 tons.

4 empty bags weigh >2% of achievable load savings in transportation, labor, and downtime of equipment under test minimum floor loading during staging of weights load measured accurately with certified load cell or flow meter wide range of bags for all sorts of testing parameters different weight capacities achieved with single rigging using manifold and valve systems.

11 ISO 9001:2008 FS Water Weights bags are fully certified and tested in accordance with government requirements and regulations.

12 ISO 9001:2008 FS How are they tested?

22 Jim Bentley Vice President, Imes Inc Maximising Remaining Useful Life of Lifting Assets

23 My Glossary of Terms Design Life Original life of asset based on the as designed (specified)condition (design code used, loads to be carried, for how long and in what environment etc). Life Extension Operation under the as designed criteria for extended period. Change of use Alteration to one or more of the original design criteria (loads to be carried, frequency of lift, environment etc).

24 Change in Methodology Traditional approach based on prescriptive test and inspection. This approach has in generally served us well but tends to manage assets on a day to day, week to week basis. Risk Based approach based on design condition, actual service loadings and degradation with sights set on required life of asset. This approach produces an organic maintenance plan based on results of each inspection/maintenance cycle.

25 Limitations of Prescriptive Testing Overload Testing Potentially More Harm Than Good Unable to Benefit From Experience Lack of Flexibility

26 IN SERVICE DATA INSPECTION DATABASE TESTING DEFECT REPORTS DATA MINING & ANALYSIS TOOL DESIGN DATA MANUFACTURING DATA STRUCTURAL ANALYSIS LOAD TESTING BASELINE NDE SAFETY CASE STATISTICAL DATABASES RISK RISK BASED INSPECTION SCHEDULE Evaluation of Current Condition

27 Risk Based - Objectives Continued safe, cost effective operation and management of mechanical handling assets through programmed life. Compliance with relevant legislation and corporate requirements Risk based system to target inspection and mitigation measures Provide an auditable trail Traceability for all decisions made Manage information interfaces Effective control of costs and resources Reduce Life Cycle Cost Added value

33 Installed Crane Crane Example 1989 i.e current 24 years of service Design Life 25 years to CMAA 70 Regular use intermittent operation 100K to 500K cycles Mean Effective Load Factor to 0.85 Customer desire to operate crane until 2040 as a hard target with stretched targets of 2060 and At 2080 crane would be 90 years old.

34 Life Extension Approach Establish current condition Review design code and any legislation changes Visual inspection Instrumented load test (AE/Strain gauges etc) Review existing or develop Finite Element Model Apply current inspection conditions to model Review current inspection, test and maintenance activity Complete risk assessment of design and operational use past, present and future.

35 Life Extension Cont. Against identified risks map current inspection, test and maintenance activity to give level of mitigation Continue doing activity that underpins risk mitigation Stop doing activity that does not contribute Start doing activity that reduces risk to acceptable level ALARP/ALARA

36 Life Extension Cont. Collect usage data (fatigue) and apply to design calculations. Establish where crane lies on fatigue clock Use fatigue history to establish when in future crane will exceed maximum mean effective load factor end of life date Use information to plan re-capitalization of asset

37 Mean Effective Load Factor Hook Load (lbs) Recorded lifts during lifetime 24 years (288 months) Load/Rated Capacity W W 3 Est. lifts/total lifts, P k 3 = W 3 P < < < < < < < < < < Totals Estimated value of k = = For a Service Class D (Heavy Service) crane, Load Class L 3 and N 2 load cycles k = to 0.85 (ref. CMAA#70 Table 2.8-1) Hence the crane usage to date is within the mean effective load derived from the load spectrum

38 Projected Life For the crane the mean effective load factor k = 0.85 max. Hence k 3 = compared with at present. Hence, for the same load distribution the crane life will be (0.6141/0.2225) x 24 = years. If the installation date was at the beginning of 1989, the max mean load factor will be met in the year 2055.

39 And Finally. In all you do just remember that when faced by a strong challenge an appropriately strong response is needed
