Should a machine be used outside its normal field of application, the suitability of this ma 
chine shall be verified and certified in accordance with the German Machine Ordinance. 
Deviations from the German and international standards and guidelines listed above shall be 
submitted to the BSH for approval. 
2.5.3 Requirements and required verifications 
During the operation of offshore structures, the approval holder shall ensure the integrity of 
the structure and that the installation has the lowest possible impact on the environment. In 
order to guarantee this, the structures and their components shall be subjected to recurring 
inspections and examinations at event-orientated intervals during the whole life cycle of the 
structure. These inspections shall be carried out by an independent third party in accordance 
with the test and inspection plan and within the scope of the concept for conducting periodic 
inspections (please refer to chapters B1.3.5, B4.5 and B5.5.3). 
Which parts of the support structure need to be inspected depends on the type of structure 
concerned. A differentiation needs to be made here, for example, between concrete and steel 
structures. 
For the periodic inspections, an object-specific and site-specific checklist (test and inspection 
plan) shall be compiled based on the technical documentation. This shall contain object and 
site-specific assessment criteria. The test and inspection plan shall primarily include those 
parts of the structure relevant to the stability of the whole structure. 
The minimum requirements pertaining to the periodic inspections of the support structures 
are listed in Table 2-1. 
When compiling the inspection plan, components that have a negative effect on humans and/ 
or the environment in the event of a failure (e. g.: outer rail, platforms, grids, ladders, collecting 
basins for environmentally hazardous substances) should also be given due consideration 
alongside those support structures listed in Table 2-1.
