<strong>Lifting</strong> <strong>operation</strong>al hazardsWhat is the Hazards with this ?- Offshore lift- Dynamic load factors- Hook snags to the supply boat- Motions of the <strong>wind</strong>mills ( floater)- Limited deck area on the vessel- Wind loads- Obstructions along the foundation- Sightlines- <strong>Lifting</strong> is done over the boat deckClassification: Internal 2010-04-28Typical Offshores cranes on <strong>wind</strong>mills•Typical <strong>offshore</strong> crane•Chain hoist•Manual slewing device•Lack of safety systemsClassification: Internal 2010-04-28

How to achive a safe design•Start with <strong>operation</strong>al questions.- What is our need for a lifting device:- Weights of the loads- Size-Frequence of use- Operational <strong>wind</strong>ow- <strong>Lifting</strong> height- Hosting speed- Design lifeClassification: Internal 2010-04-28Hazard involved•What is the <strong>operation</strong>al hazards involved- Danger of falling objects- Weather conditions- Movement of the ship and plant-Working area- Sight lines- Method of communication- Based on this we can establish the necessary technical requirementsfor a lifting crane on an <strong>offshore</strong> <strong>wind</strong> farm,Classification: Internal 2010-04-28
<strong>Lifting</strong> at <strong>wind</strong>mills, rules and regulation•What rules do we have and how can we use them ?.- Maritime rules ?- Classification society rules for shipboard cranes ( DNV. LRS, ABS) ?- Machinery directive ?- Based on the fact that the <strong>wind</strong> mills are permanently installed/anchored to the seabed, the Machinery directive should apply withinEEC- In addition to national laws and standards, in the county the <strong>wind</strong>millsare mounted- The lack of product standard covering lifting devices on <strong>offshore</strong><strong>wind</strong>mills and relevant safety system is our main consernClassification: Internal 2010-04-28What standards should be used• Machinery directive 2006/42/EC main document• Harmonized EN standards relevant to the product ( winch, steel, welding).• EN-13852-1 with reference to safety system relevant for this applicationRelevant safety system:AOPSMOPSEMC lowering of the loadOther technical requirement to ensure safe <strong>operation</strong>s i.e:• Slewing drive unit, ensuring safe slewing motion• Remote control <strong>operation</strong> of winch / chain hoistThe final solution must also take into account the cost aspect, and find costeffective solutions, based on the involved riskClassification: Internal 2010-04-28
Operation /TrainingBased on the involved risk.•Roles and responsibilities must be clear•Operational procedures must be written•Proper training•Crane operator competence. ( <strong>offshore</strong> crane)•Banksmen/ slingers competence•Norsok R003 can be used as a guidelineProper training is the key to safe lifting <strong>operation</strong>s80% of the accidents is a result of the lifting i <strong>operation</strong> itself.20% is other causes and technical issuesClassification: Internal 2010-04-28Maintenance•Maintenance should be based on FMECA•RCM analysis•Based on risk and reliability.•Limited access to the <strong>wind</strong>mills during winter is a challenge•Very limited use of the lifting davit.Preservation can be a bigger issue, than maintenanceClassification: Internal 2010-04-28
