DNVGL - DNV-RP-C301
Design, Fabrication, Operation and Qualification of Bonded Repair of Steel Structures
|Publication Date:||1 April 2012|
Objective and scope
The main objectives of this Recommended Practice (RP) are to:
- provide an accepted industry practice for using bonded repair
- serve as a technical reference document in contractual matters.
This RP provides:
- An assessment and decision making process on whether to proceed with a bonded patch repair.
- A design and qualification process to design and fabricate bonded patches.
The scope of this RP covers design, materials, structural analysis, fabrication, testing, in-service inspection and maintenance of bonded repairs. Aspects relating to documentation, verification and quality control are also addressed.
A repair might be rehabilitation of fatigue cracks in a structural element or bridging of cracks in corroded (structural or non-structural) tank plating.
Furthermore, this technology could be used for modification or upgrading by reinforcing structural elements to provided added capacity.
The repair procedures covered by this RP utilizes patches of composite material, steel or other structural materials that are bonded to an existing steel structure.
