This has driven the development of a number of standards and recommended practices, giving both general guidance and specific methodologies for design of dnv rp b401 CP systems and for the manufacturing and installation of galvanic anodes.
Firstly, the cost ro the CP system may be significantly reduced when fewer anodes have to be installed.
New DNV Recommended Practices for Galvanic Anode Marine Cathodic Protection – OnePetro
As in the NACE code, the first issue of RP-B did not describe the CP calculation procedures in any detail; CP dnv rp b401 parameters related to the performance of galvanic anode parameters were defined as typical ranges, and?

Comparison is also env with other CP codes, both in terms of the general methodology and by direct numerical comparison, using some illustrative examples. Prior to this, the only offshore design code dnv rp b401 addressed dnv rp b401 objectives was the NACE RP Control of Corrosion on Steel, Fixed Offshore Platforms Associated with Petroleum Production, first issued inin which galvanic anode cathodic protection was treated rather superficially.
The development of DNV recommended practices for cathodic protection is described in detail, with reference to significant changes made for certain design parameters and the reasons behind such amendments.

However, during this period, increased service experience has lead to a refinement in the rl specified in the relevant codes and dnv rp b401. Log in to n401 subscription Username. Secondly, for certain linepipe materials the risk of cracking failure modes associated with hydrogen absorption induced by cathodic protection can be reduced, especially if CP can be provided from anodes located on adjacent structures.
