6 Deviations from the standard 
The geotechnical expert can make a reasoned suggestion to the applicant or approval holder 
to agree to deviations from what is established in this guideline during the ongoing project 
phase if it can be shown during the course of the project that parts of the survey and investi 
gation programme are inadequate, unnecessary or cannot be carried out in the suggested 
manner or only by means of disproportionate effort due to site conditions or other reasons. 
A corresponding proposal can be submitted as part of the regular construction meetings with 
the Federal Maritime and Hydrographic Agency with consultation from the geotechnical ex 
pert and the inspector within the context of Standard Design. The approval authority reserves 
the ability to allow the survey and investigation programme in general to go ahead, to allow it 
on a case-by-case basis or to adapt it if necessary. 
Further statements regarding transitional, deviation and supplementary rules are contained in 
Part C, section 1.3. 
7 Updating 
The current guideline illustrates the present state of knowledge and technology behind ground 
surveys and investigations for offshore structures. It is understood as being a dynamic, ongo 
ing concern. New experiences and knowledge which can be expected when implementing 
further construction projects are observed and added to the work where necessary.
