Note that most of these cranes do NOT come under the ILO Article 25(2) of the Occupational Safety and Health (Dock Work) Convention for Lifting Appliances for testing and maintenance. They are NOT ships cranes, they are shore cranes and therefore must be certified and tested under the National Occupational Health and Safety Rules and Regulations.


If you are involved in Marine Warranty Surveys that require the use of these ‘big cranes’ you should be aware of the testing regimes for the cranes as well as all the loose gear, shackles, slings, spreaders, etc.


Normally a qualified ‘Lifting Engineer’ will prepare the lifting plans and this will in turn be checked by the company providing the Marine Warranty Survey service. This is NOT a job for the Marine Warranty Surveyor.


The Warranty Surveyor must be provided with a clear scope of work and ensure that he/she is provided with all the necessary ‘approved’ lifting / loading / slinging procedures. Then the surveyor can follow this procedure and confirm that all necessary steps are followed.


Heavy lift ship delivering modules to HHI shipyard. Mooring arrangements are part of MWS scope.


There are many other specialist heavy-lift machines used for the loading and discharge of modules.


Heavy lift transporters (Self-Propelled Module Transporter – SPMT) are often used to lift and manoeuvre modules off a


transport vessel and onto the quayside at the receiving yard. These transporters need to be certified and fit for purpose.


Hyundai Heavy Industries 10,000 ton SWL floating frame.


The use of Goliath Cranes in shipyards is a ‘normal’ operation that is NOT normally a MWS requirement unless it is a


particularly high value or unusual asset that is being lifted. This crane at HHI is rated to 1,600 ton SWL and can work in


Each hook has SWL 1250 ton. There are eight independent hooks.


In all shipyards around the world lifting operations within the yard are normally not considered Marine Warranty Survey items. These are day-to-day work for the yard to manage and manage the risks. Marine Warranty Surveys (MWS) normally require the surveyor to witness the safe delivery of the components and set them down at the receiving yard. That is the point at which the Marine Warranty ceases and the asset comes under the shipyard’s risk management and insurance cover.


I hope this article has been of interest to you, as a brief exposure to Marine Warranty Survey ‘Heavy Lifts’. Many more items within the scope of Marine Warranty Surveys are not mentioned here and can form part of future articles.
