TECHNICAL DATA SHEET C-CLAWTM Non-intrusive and heavy-duty fastener for steel structures A true alternative to welding and drilling

C-CLAW BONDED FASTENER COLD PAD has developed C-Claw, a heavy-duty fastener with a process-controlled installation that is non-intrusive, reliable, safe and durable. C-Claw is specially designed for marine and offshore environments like FPSO, where hot works generate a considerable number of constraints, shutdowns, and risks. It truly is revolutionary in the marine world and was inspired by composite techniques that have been used for decades in aeronautics. ADHESIVE COMPOUND PERIPHERAL SEAL strongly bonds the fastener to the base structure protects the adhesive compound from the external...

INSTALLATION EQUIPMENT C-HAWK: A PROCESS-CONTROLLED TOOL Adhesive bonding operations require a good control of the whole bonding procedure (control of atmospheric conditions, surface preparation, adhesive preparation and application, polymerization…). C-Hawk proprietary tool offers a perfect control of the bonding operations in harsh “industrial” environment by creating optimum atmospheric conditions locally, for repeatable performance, even for marine applications. C-Hawk is a low power tool and can be use in hazardous areas (with potentially explosive atmosphere) C-CLAW PARTS AND...

C-CLAWTM OPTION: ENCAPSULATED C-CLAW When the environment is permanently wet, C-Claw sealing can be reinforced with an extra external sealing protection composed of an external seal and a stainless-steel cap. This external sealing system is installed after complete curing of C-Claw adhesive.

C-CLAWTM C-CLAWTM C-CLAWTM C-CLAW INSTALLATION PRELIMINARY SURVEY PRIOR TO INSTALLATION Several controls shall be done prior to C-Claw installation: LOADS ✓ Loads intensity and loads duration are admissible for the intended application as per table in page 6. TEMPERATURE ✓ The temperature of both the base metal and the C-Claw shall be within an acceptable range for the installation, as per table page 6. ✓ The expected temperature of the base metal shall be within an acceptable range for the intended application, as per table page 6. BASE METAL ✓ The base metal is made of steel (any typical...

C-CLAWTM C-CLAWTM C-CLAWTM REMOVAL If necessary, C-Claw can be removed with a specific tool, called C-Claw remover, developed by COLD PAD and provided as an option with the installation tool C-Hawk. C-Claw cannot be reused after removal. SURROUNDINGS C-Claw fastener can be exposed to the marine environment (relative humidity up to 100%, sun, seawater without permanent immersion). Contact with hydrocarbon may occur if it remains occasional. Accidental design events such as fire, blast and impact/dropped object are excluded at this stage. TRAINING C-Claw can only be installed by trained and...

C-CLAWTM C-CLAWTM C-CLAWTM SAFETY, HEALTH AND ENVIRONMENT Impact of in-service C-Claw fastener on safety, health and environment is low for low safety class application. Accidental cases such as fire are excluded although a quantitative risk assessment has been performed for the particular case of a handrail fastened with C-Claw and submitted to fire. For critical application such as lifting lug, C-Claw shall be proof tested at its nominal capacity multiplied by a coefficient above 1 to ensure it will be safe. The coefficient will depend on the application and the regulatory requirements....

C-CLAWTM FICHE TECHNIQUE Fixation robuste et non invasive pour les structures en acier Une véritable alternative au soudage et au perçage

FIXATION MÉCANIQUE C-CLAW COLD PAD a inventé C-Claw, une fixation collée robuste non-invasive, durable, sûre et fiable. C-Claw est conçu spécialement pour les unités navales et offshores telles que les FPSO, où les travaux à chaud sont sources de nombreuses contraintes, d’arrêts de productions et de risques. C-Claw est une technologie révolutionnaire pour le secteur maritime inspirée par des techniques composites utilisées dans l’aéronautique depuis des décennies.
