Secondary steel is not, generally holiday tested., It is not reccomended to carry out HV holiday testing over TSZA. Our experience shows DFT's of the metallization generally have a wide variation from, NDFT to several hundred pm., In some spots this may result in a high DFT of metallization and low DFT of coating system. Whilst the total DFT may meet the specification, the low DFT of, coating system in such spots may result in damages to coating and impact accuracy of holiday testing., Testing, The suggested frequency for testing shall be 5% of the total coated surface. The location of the 5% shall be agreed by Tendererlders and the Client Representative prior to testing., A Maximum of 5 findings per 100 m2 of the tested surface are acceptable. A finding is defined as a spot of max. 0,1 m2 with one or various detected pores., In case of more findings and/or one of the spots exceeds the max. size, the next level of testing has to be applied., In case of more then 5 findings per 100 m2 tested surface, additional +10% surface is measured. . If no further pinholes are detected, the coated surface is, accepted. If additional pinholes are detected, the entire coated surface is checked., All findings have to be repaired according the agreed repair procedure., A retest of the repaired spots will not be performed. It is not reccomended by the paint manufacturer and holiday testing the same area more than once, could lead to the unnecessary damages of already Sound coatings., Principle, Porosity in a protective paint system applied to a conductive metal surface is detected either by low-voltage wet-sponge testing or high-voltage spark, testing., Low-voltage pinhole detectors use moisture to conduct electrical current through any discontinuity in the coating.Following Note to be included in qualification list :, For the design of the grouted connections !between foundation piles and jacket structure) the formulations and verifications as per Norsok N-004 !2021), will be used. This guideline will be used in favour of DNVGL-ST-0126 !and DNVGL-ST-0145) on the basis that the methodology as proposed by the DNV, guidelines has originally been developed for monopile-type foundation and not so much for !pre-piled) jacket type foundations. Even more, DNVGL-, ST_0126 explicitly refers to Norsok N-004 for further recommendations on this type of foundations. Therefore, in order to limit the axial movements within the grouted connection, as per the requirements on Early Age Cycling within Norsok N-004, a single pile gripper ring with horizontal jacks will be included, at the upper regions of the grouted connection assemblies.Smulders has for each Technique a standard procedure reviewed by DNV available., These are followed without extra requirements.Several reference blocks available per site., Available blocks cover majority of scope, Specific reference block needed !Design) ==> available as required per NDT standard., Blocks with similar material as used in project, Blocks from specific project material is excluded from the contract., For thickness range of blocks SMU follows DNVGL !the 10% as per EN standard will not be followed).according to standards:, As per standard with remark, DNV-project : Ask for reduction to 24 hrs., 1st option: Provide statement R-TI-GR-301 with previous experience 2nd option: Proposal 48 hrs. first X-pieces then reduced !still impact!, but limited), EN: as per table Method A = SMYS < 420 Mpa, Method B = SMYS > 420 Mpa, Repair, Superficial: no hold time (Dept of repair < 5mm) Volumetric: as per original weldRequest to be made to replace RT inspection by manual UT or recorded UT if manual UT is not accepted.VT-MT-PT !superficial NDT), Indications marked on the piece for rework, Re-testing after rework, Report made after rework to approve piece, Except: if crack-indication is found this will be seperatly reported, UT, If non-acceptable indication is found ==> report will be made, Re-test after repair ==> new report will be made, Acceptable indications will be reported as per standard, Signature on report by either:, Operator who performed inspection, Level 3 of NDT company who performed inspectionAs per the standards, As per the organigram and job descriptions taken into account into the difference quality management certificates., Standards describe which level of qualification is required for certain inspections., Some examples:, Welders : EN ISO 9606-1 Weld operators: EN ISO 14732, Welding coordination: As per the NDT standardSmulders has certification according the different quality standards, workshop are organized to comply to the quality standards, Certification of companies is done according to quality standards:, EN1090-2, EN3834-series, DNV Workshop approvals, Deutsche Bahn, ... Certification to these quality standards prove a system to guarantee the quality in production is in place.Reuse of existing, standard reporting, extend of testing visual less strict and minimum preheat,-Normal and high strength Steel with SMYS <S355, similar to Method A of the EN 1011-2 taking into account WPQRS, Based on combined thickness, -extra high strength steel (SMYS >420MPa) based on thickness of the thickest member in the connection, similar to method B of the EN 1011-2 taking into account WPQRS, Standard preheat is performed with gas burners.

Introducing new feedback at this stage on previously available content is not considered viable., Any changes to this proposal may have cost and planning implications for the project. Such impacts will be communicated through the Variation Order, !VOR) process. Employer representatives attending inspections must have the authority to sign and validate inspection records and related documents. This should be, clarified in advance by the EMP project team prior to the start of inspections., By default, any individual delegated by EMP to attend an inspection will be deemed to hold this authority, and their signature will be considered valid.AWS D1.1 to be used on robot weldingdesigner determines in his design already requiremend so should be wavered by oursWorks are to be performed according fabrication standard based on the chosen design standard !and/or local applicable laws, f.e. BSH-requirements)., For Items missing in a fabrication standard reference can be made to another fabrication standard., Purpose is not to combine different standards and choose the most stringent, as design standards don't take this into account., Extra requirements of employer on certain items will not change design life of a structure or improve the quality !see some examples):, Increased thickness tolerance base material, Narrowed qualification ranges of WPQRs, Purpose should also be to be involved in design as soon as possible:, Avoid non-executable connections, Avoid unnecessary/ impractical stringent fatigue clases, Avoid unnecessary stringent tolerancesPreheat is not recorded as this is not specified in the different fabrication standardsDocument related to inspections !e.g. NDE-reports, Dimensional reports) will be available at certain inspection steps !e.g. Black steel inspection). These are, possibly only draft versions !work version from workshop)., We can't guarantee that final reports such as NDE or Dimensional reports can/will be provided to Employer x hours after inspection. Weld related reporting shall be however available after coating worksTemporary attachments are required to assemble certain items before welding to already give some temporary structural strenght., To be allowed everywhere !except where highlighted on design drawings), No traceability of used material (All grades with SMYS < 460MPa should be allowed), Not to be included on WSD and/or ASB drawings, With regards to removal, Cut 3mm above base material, Grind flush VT+MT to be performed, 1 Report to cover all locations of temporary attachments !no traceability to locations).If not specified by the client, keep it simple. If explicitly mentioned, no challanged, add additional cost impact.Keep it away as much as possible., If possible use leverage being sub-contractor of SIF. !this normally applies to main contractor), If unavoidable, consider additional costStandart Proposal For Subctontractors, Check the requirements - 10-15 days, Notification: Western EU !Benelux) 3-5 days, Outside of Benelux - 10-15 days, Outside of Europe - 30 daysPowder coating to be established for hinges etc.. or stickers for anti-skidTendererlders tries to avoid Zn-rich primers, and prefers above all long-track record Tendererlders Standard coating systems., Zinc primers are extremely difficult in serial manufacturing, and would increase prices:, - extreme tight tolerances on film thickness: 80 - 150 p ( min 64p, max 150p ), There is a risk on reaching too high thickness, which results in grinding repairs., On secundary steel or corners this is critical (corners, edges, .. ), - Ethyl Zinc-rich primer on friction areas requires humidity to cure., - Under- and Over-application needs to be blasted off due to stresses in the coating and cohesion failure., - Potential for cracking in corners and welds due to high thickness, There are currently systems in the market which provide equal corrosion resistance and therefore a deviation might be required, e.g.:, Glass Flake systems such as IZ-954-GF (despite the process related difficulties ( wear out pumps, .. ), High solids !aluminium) pigmented epoxy systems with proven track recordsIn general max. and min. DFT are technical and material specific values with no relation to project specific NDFTs., For materials often used by Tendererlders we have already received a list from International Paint regarding these values !s. R-TI-GR-317)., As long as the same kind of binder is used for the next layer:, All low (< 80% or rather 90% of NDFT) and high DFT's (> 2,5 x NDFT) are marked during inspection., Only areas with values outside the specified limits acc. R-TI-GR-317 are reworked by touch up or sanding !also in combination with a touch up), All other low and high values are compensated with the next layer., As for every touch up the min. overcoating time !several hours !) has to be respected before application of next layer this approach leads to a significant, safe of time and costs without affecting quality and/or the functionality of the corrosion protection system.For large constructions such as decks, TP's, etc, is the time frame limitation between blasting and the 1st coat as described in the VGB not feasible., A derogation shall always be requested when this requirement applies., Independent of the time between blasting and the application of the 1st coat, Tendererlders ensures the quality by checking the cleanliness of the blasted, Independent of the time between blasting and the application of the 1st coat, Tendererlders ensures the quality by checking the cleanliness of the blasted, surface just before !max 1 hour) applying the 1st coat !Stripe coat start process first coat).Tendererlders complies with the conditions defined by Norsok., The product data sheet of the paint manufacture shall be taken as minimum requirement.Tendererlders way is to agree on what is achievable in the field., Tendererlders way is to agree on what is achievable in the field.
