1. DESCRIPTION Generell The Blohm + Voss Safety Clamp is available as Type "T" from 1.1/8" to 4.1/2" with a special design for small pipes and as Type "C" from 3.3/4" to 42" for larger pipe sizes. The Intermediate Links and Inserts (wedges) of the two types are not interchangable. The Type "C" Clamp is also available with a pneumatic kit to improve speed at tightening the Clamp. From 3.3/4" to 22" with pneumatic kit 99630 and from 22" to 42" with pneumatic kit 99650. Intend of use DESCRIPTION The Blohm + Voss Safety Clamp is desigend for being fastened on a flush joint tubular and allows lifting of a single joint whereby the Type T and C Blohm + Voss Safety Clamp has to be used together with a single joint elevator or together with Handslips. The safe working load of the safety Clamp Type "C" is 10 sh tons and must never be exceeded. Never use Blohm + Voss Safety Clamp as a hoist Tool. Function When the Blohm + Voss Safety Clamp is triggered, each individual insert instantly grips tightly on the surface of the pipe. If the pipe string weight takes effect, or should there be any increase in the load on the inserts, the conical mount causes the insert to be pressed more tightly against the surface of the pipe, i.e. the pipe is secured against any further movement by means of the Blohm + Voss Safety Clamp. The gripping pressure at all points around the pipe is always uniform minimizing risk of crushing thin-walled pipes or damaging the pipe surface. As each link, complete with conical insert, can be interchanged as an assembly with the other links, the Blohm + Voss safety clamp Type "T" can be used from 1.1/8" to 4.1/2" and Type "C" from 3.3/4"-42" in diametre and from -20 C (-4 F9) to +40 C (176 F) if not otherwise stated in the Databook. All parts are made by heat-treatment hardened steel and are suitable for maximum load and maximum gripping safety. WARNING: Welding on any part is not allowed. Main Assembly 1.

INSTALLATION INSTALLATION 19

2. INSTALLATION The Safety Clamp Type "T" and Type "C" always has to be used with a Single Joint or Handslips. Put the Safety Clamp around the pipe and bring all Links into gripping position. The Safety Clamp lock or pneumatic lock now has to be fastened. While fastening you have to make sure that all Inserts are gripping properly. The Safety Clamp is sufficient gripping, when the torque of the nut or the pneumatic screw is above 135 Nm and below 400 Nm. Too much tightening can cause loss of safe working load up to destroying the Safety Clamp. The pneumatic impact wrench has to be set on position II or is already in this default. This adjustment guarantees a suitable torque. The Nut is fastened, when the impact wrench is starting to slip stick. INSTALLATION 20

OPERATIONS OPERATIONS 21

3. OPERATION After installation of the safety clamp, follow the following guidelines. WARNING: NeveR use the SAfety CLAMP ALONE AS A hoist tool Standard clamp The Safety Clamp, which is fastened on a flush joint tubular, allows lifting of a single joint whereby the Safety Clamp has always to be used together with a single joint elevator or handslips, to lift single joints from cantilever to the rig floor. The safe working load of 10 short tons must never be exceeded. Safety Clamp pneumatic kit P/N 99630 with Single Joint OPERATIONS Pneumatic clamp The clamp is handled as normal safety clamp around the pipe. The Pneumatic kit replaces manual tightening through a wrench and sledgehammer. The Pneumatic kit (P/N 99630) is used to turn the Left/Right hand threat bolt and the different threads will tighten the Clamp. The Pneumatic kit (P/N 99650) uses a mounted threat bolt for tightining the Safety Clamp. The Pneumatic kit uses a pneumatic Screwdriver to tighten the clamp.

Inspection categories acc. to API RP 7L Category I This 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 II This 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 III This 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 IV This 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 suitableequipped facility to the extent necessary to permit full inspection of all primary-loadcarrying 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. paintstripping, steam-cleaning, gritblasting) Frequency Periodic inspection The recommended schedule for inspection of Safety Clamps are Ongoing: Inspection category I Daily: Inspection category II Every 6 months: Inspection category 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 Oil Tools or an authorized service company. MAINTENANCE & INSPECTION 25

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 Oil Tools. Weldings at the castings should be done only by Blohm + Voss Oil Tools 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. MAINTENANCE & INSPECTION 26
