(o) Under emergency conditions, you § 2110.901 What industry standard! must your platform meet? may make repairs to primary struc

tural elements to restore an existing permitted condition without submit-ting an appl!oation or reoeivfng prior MMS approval for up to 120-cale11dar days following an event. You must notify the Regional Supervisor of the damage that occurred within 24 hours of its discovery, and you must provide a w1•i tten completion report to the Regional Supervisor of the repairs that were made within 1 week after com.. plating the repairs. If you make emergency repairs on a floating platform, you must also notify the USCG.

(d) You must determine if your new platform or major modification to an existing- platform is subject to the Platform Vei:ifieatlon Program (PVP). Section 250.910 of this subpart fully describes the fao!lftles that are subject to the PVP. If you determine that your platform is subject to the PVP, you must follow the requirements of §§ 250.909-250.918 of this subpart.

(e) You must submit notification of the platform installation date and the final as-bu!lt location data to the Regional Supervisor within 46-calendar days of completion of platfo+m installation.

(1) For platforms not subject to the Platform Ver!fioaticn Program (PVP), MMS will cancel the approved platform appl!cation 1 year after the approval has been granted if the platform has not been installed. If MMS cancels the approval, you must resubmit your platform application and receive MMS approval if you stm plan to install the platform.

- (2) For platforms subject to the PVP, cancellation of an approval will be on an individual platform basis. Fi;ir these platforms, MMS will identify the date when the installation app1•cva! will be cancelled (if installation has riot ocourred) during the application and approval process. If MMS cancels your Installation approval, you must resubmit your platform application and receive MMS approval If you st111 plan to Install the platform.

Depending upon the design and location of your proposed platform and the results of the shallow hazard and geologic surveys, the Regional Supervisor may require you to perform a su!J8urfaoe survey, 'rhls survey will include a testing program for investigating the strati graphio and engineering properties of the soil that may affect the foundations or anchoring systems for your facility. The testing program must in-· elude adequate in situ testing, boring, and sampling to examine all important soil and roe!~ strata to determine !ts strength classification, deformation properties, and dynamic charaeteristics. If required to perform a subsurface survey, you must prepare and submit to the Regional Supervisor a

summary report to briefly describe th• results of your s9!1 testing program the various field and laboratory tes methods employed, and the applica blllty of these methods as they perta11 to the quality of the samples, the typ. of soil, and the antioipated design ap plication. You must explain how th• engineering properties of each sol stratum affect the design of your plat farm, In your explanation you must de scribe the uncertainties Inherent ii your overall testing program, and th reliability and applioablllty of eacl test method.

(d) Overall s'lte investigation repori You must prepare and submit to th Regional Supervisor an overall site in vestigation report for your p!atforr. that integrates the findings of you shallow hazards surveys and geologi surveys, and, if required, your sut surface surveys. Your overall site in vestigation report must include anal yses of the potential for:

(1) Scouring of the sea.floor; · (2) Hydraulio Instability; (3) The occurrence of sand waves;

. (4) lnstability of slopes at_ the plat form location;

PLATFORM VERJFIOATION PROGRAM

§ 250.909 What . is the Platform Verification Program?

The Platform Verification Program is the MMS approval process for ensuring that floating platforms; platforms of a new or unique design; platforms In seismic areas; or platforms located In deepwater or frontier areas meet stringent i•equ!rements for design and construction. The program ts applied during conatruotion of new platforms and major modifloatlons of, or repairs to, existing platforms. These requirements are in addition to the requirements of

spections described in section 14.4.3 of API RP 2A-WSD (incorporated by reference as specified in §250.198); and

(3) An inspection plan for each structure that desoribes· the work you ~vill perform to determine the condition of the structure.

(o) 'i'he Regional Supervisor mity also require you to submit the results of the inspections referred to in paragraph (b)(2) of this section, including a description Of any· detected damage that may adversely affeot structural integrity, an assessment of the structure's ability to withstand any anticipated environmental conditions, and any remediation plans. Under §§250.900(b)(3) a'nd 250.906, you must obtain approval from MMS before you make major repairs of any. damage unless you ineet the requirements of§ 250.900(c),

§250,920 What are .the MMS require· ments fot• assessment of fixed platforms?

(a) You must doourrient all wells, equipment, and p1p·e11nes supported by the platform if you intend to use either the A-2 or A-'l assessment category, Assessment oategories are defined In API RP ::!A-WSD, Seotion 17.3. If MMS objects to the assessment category you used for your assessment, you may need to redesign and/or modify the platform to adequately demonstrate that the platfo"'m is able to withstand the environmental loadings for the appropriate assessment category,

(b) You muat perform an analysis oheolr when your platform will have additional personnel, additional topside facilities, Increased environmental or operational loading, or inadequate deck height your platform suffered significant damage (9.g., experienced damage to primary structural members or conductor guide trays or global structural Integrity Is adversely affected); or the exposure category changes to a more restrictive level (see Sections 17.2.l through 17.2.5 Of API RP 2A-WSD for a description o.f assessment initiators).

(o) You must initiate· mitigation actions for platforms that do not pass the assessment prooeee of API RP 2A.. WSD. You must submit applications for your mitigation actions (e.g., repair, modif!oat!on, decommissioning) to the Regional Supervisor for approval before you.oonduot the work.

(d) The MMS may require you to conduct a platform design basis cheolt when the reduced environmental loading crlter!a conta!ned In AP! RP 2AWSD Seotlon 17.6 are not applicable.

(e) By November l, 2009, you must submit a complete list of all the platforms you operate, together with all the appropriate data to support the assessment oategory you assign to each platform and the platform assessment initiators (as defined In API RP 2AWSD) to the Regional Supervisor. You must submit subsequent complete lists and the appropriate data to support the consequence-of-failure category every 6 years thereafter, or as direoted by the Regional Supervisor. •
