3. OPERATION
Extreme Low Temperature
Ratings have been established at a temperature of minus 20°C. The effect of low temperature on steel must be recognized although no changes in design safety factors have been provided. When operating at low temperatures, caution must be exercised to take into account the lower impact capabilities of many steels which are typically employed. The risk of failure may be reduced by a critical load inspection.

4. MAINTENANCE & INSPECTION
General
If cracks, excessive wear etc. is recognised, contact Blohm + Voss Repair GmbH or an authorised service company.Weldings of the castings should be done only by Blohm + Voss Repair GmbH or an authorised service company in according to Blohm + Voss welding procedure.
Deterioration of equipment
Normal wear in course of use will eventually reduce the capability of the elevator links. The existence or cracks, or the appearance of defects, can indicate severe deterioration, even impending failure, and prompt attention is required either to remove the elevator link from service immediately, or to undertake appropriate repair as required.
Records
Inspection procedure are listed in this recommended practice and generalized sketches of the elevator links showing points to be inspected are to be provided. Written records should be maintained which accurately record the inspection and maintenance history of each elevator link. Records should include the date, personnel involved, and results of each inspection or maintenance procedure performed.
WARNING: NeveR Weld oN elevAtoR lINks!
Dismantling
The elevator links should be dismantled from the rig and inspected in a usitably equipped facility for excessive wear, cracks, flaws or deformation. Corrections should be made in accordance with recommendations which can be obtained from Blohm + Voss.
Cleaning
Before inspection, all foreign material such as dirt, paint, grease, oil, scale, etc. should be removed from the areas to be inspected by a suitable method.
Inspection Procedure
The inspection should be made by trained, competent personnel.

Category IThis category involves observing the equipment during operation for indications of inadequate performance.When in use, equipment shall be visually inspected on a daily basis for cracks, loose fits or connections, elongation of part, and other signs of wear, corrosion or overloading. Any parts found to show cracks, excessive wear, etc., shall be removed from service for further examination.The equipment shall be visually inspected by a person knowledgeable in that equipment and its function.
Category IIThis is Category I inspection plus further inspection for corrosion, deformation, loose or missing components, deterioration, proper lubrication, visible external cracks, and adjustment. Category II may involve some disassembly to access specific components and to identify wear that exceeds the allowable tolerances.
Category IIIThis is Category II inspection plus further inspection, which should include NDT of critical areas and may involve some disassembly to access specific components and to identify wear that exceeds the allowable tolerances.Prior to inspection, all foreign material such as dirt, paint, grease, oil, scale, etc. shall be removed from the concerned parts by a suitable method (e.g. paint-stripping, steam-cleaning, grit-blasting).
Category IVThis is Category III inspection plus further inspection for which the equipment is disassembled to the extent necessary to conduct NDT of all primary-load-carrying components.
Equipment shall be:disassembled in a suitable-• equipped facility to the extent necessary to permit full inspection of all primary-load-carrying components and other components that are critical to the equipment.inspected for excessive wear, • cracks, flaws and deformation.
Procedure:Corrections shall be made • in accordance with the manufacturer’s recommendations.Prior to inspection, all foreign • material such as dirt, paint, grease, oil, scale, etc. shall be removed from the concerned parts by a suitable method (e.g. paint-stripping, steam-cleaning, grit-blasting)
Frequency
Periodic inspection
The recommended schedule for inspection of all kind of
Elevators:• Daily: I+II6 Monthly: III1 Year: IV
Spiders:• Daily: IWeekly: II6 Monthly: III1 Year: IV
Power Slips:• Daily: IWeekly: II6 Monthly: III2 Year: IV
The recommended frequencies apply for equipment in use during the specified period.
The inspection frequencies are only recommendations. The schedule of inspection heavily depends on the following factors:
environment• load cycles• regulatory requirements• operating time• testing• repairs• re manufacture•
Non-periodic inspection
A complete, on-job, shut-down inspection equivalent to the periodical Category III or Category IV should be made before (if anticipated) and after critical jobs (e.g., running heavy casing / drill strings, jarring, pulling on stuck pipes and/or operating at extreme low temperatures) <-20° C (<-4° F).
Inspection
A thorough inspection should be carried out periodically (every 3 months) or as special circumstances may require. Before starting an inspection disconnect hydraulic/pneumatic system and remove all foreign materials (dirt, paint, grease Oil, scale, etc.) from surface by a suitable method. After a field inspection, it is advisable to record the extent of testing and testing results. Conduct the periodic or critical load inspection in the field by the crew with the supervisor. If cracks, excessive wear etc. is recognized, contact Blohm + Voss Repair GmbH or an authorized service company.

Critical Load Inspection
Critical loads may occur. For example: impact loads such as jarring, pulling on stuck pipe, etc. If critical loads occurred unexpectedly, conduct the inspection immediately.
Dismantling Inspection
Generally, when the equipment returns to base, warehouse, etc. Carry out the Tool inspection, immediately. Furthermore, control it prior to its being sent on the next job.
The Tool should be dismantled and • inspected in a suitably equipped facility for excessive wear, cracks, flaws or deformations.Corrections should be made in • accordance with recommendations which can be obtained from Blohm + Voss Repair GmbH.Weldings at the castings should be • done only by Blohm + Voss Repair GmbH or an authorized service company in according to Blohm + Voss welding procedure.When need is shown in a field • inspection, dismantle the Tool and arrange an inspection in a suitably equipped facility.Springs should be carefully visually • inspected for excessive wear and obvious weakness.

Use of Worn Elevator Links
It is possible to approximately downrate elevator links due to wear. The following figures indicate the rating on new links and the decrease in rating by steps as the links are worn.
A periodic check should be made of worn diameters, particularly when weight levels may be involved. If a question exists as to proper rating after use, particularly if there is evidence of other damage, such as cracks, Blohm + Voss should be contacted.

Explanation how to use the table above
Example: a 3.1/2”-500t elevator link with an actual dimension f of 5.7/8”(149,2 mm) can be used with the full rated load 500 tons per set (as long as dimension f is bigger than 5.5/8”). If the dimension is equal or smaller than 5.5/8” the links have to be de-rated.
