Part B - Verifications and approval requirements 
43 
A construction log shall be kept detailing all implementation steps. This shall be made avail 
able for review. 
The approval holder is responsible for coordinating all the processes with the authorities, the 
companies carrying out the work and the appointed inspector. 
2.4.2.1 Production monitoring 
The activities of the appointed inspector incorporate monitoring activities with respect to 
verifying that the operational structure (topside) and the support structure have been manu 
factured in line with the approved implementation documents (e.g. drawings, calculations, 
specifications, verification reports) and meet the respective quality requirements. The moni 
toring of the production phase is conducted during the production process. 
The monitoring of the production phase through the appointed inspector does not substitute 
quality monitoring or self-monitoring on the part of the respective component manufacturer. 
The scope of the spot checks to be carried out whilst monitoring the production phase is in 
tended to provide a basic set of values for the respective project which allow the appointed 
inspector to confirm in a certificate of conformity that production has been carried out in com 
pliance with the requirements once the production monitoring phase has been completed. 
The monitoring services shall be carried out based on the agreed monitoring schedule. Ini 
tially, the scope of the spot checks to be carried out is understood to cover 20% of all the 
components that impact health, safety, the environment, shipping and the structural integrity 
(stability and life cycle) specially manufactured for the project. When compiling the monitoring 
schedule, the special circumstances applying to mass-produced components shall be taken 
into account, if these cannot be allocated to a specific project during their production. This 
implies that identical components may also be used as an alternative basis for the conformity 
assessment procedure for a specific project. The scope of the spot checks and the methodol 
ogy for extending or reducing the scope of these spot checks shall remain unaffected 
hereby. 
Should no serious defects be established during the production of the first 20 % of the com 
ponents to be monitored - and if there are no changes to the production process - a reduction 
of the scope of the spot checks to, for example, 10 % shall be coordinated with the appointed 
inspector (Figure 2-1 ). Prior to commencing production, the quantifiable criteria with a view to 
changing the scope of the spot checks shall be coordinated between the appointed inspector 
and the applicant, resp. approval holder. A serious defect is a defect that is expected to have 
an impact on health, safety, the environment, shipping or the structural integrity of the project. 
The respective producer is under obligation to notify the appointed inspector of any serious 
defects that may be established. In the case that a serious defect is established, the approval 
authority shall be notified of this defect immediately. In the case of a serious defect, the extent 
of the additional inspection work required as a result shall be agreed between the approval 
holder and the appointed inspector. In such cases, the scope of the spot checks may be in 
creased to, for example, 75 % (Figure 2-2) - or in an extreme case - to 100%. This shall be 
accordingly documented in the inspection report compiled by the appointed inspector in a 
comprehensible and transparent manner. 
2.4.2.1.1 General requirements with respect to the monitoring of the production phase 
In order to obtain an impression of the production company, the appointed inspector shall 
conduct an initial audit (of the production process) together with the client. This initial audit
