DRILLING STRUCTURE RECERTIFICATION
It is not unusual for customers to approach us concerned that there is no documentation and/or nameplate evidence of the capacity of their drilling structure. In this situation, the normal procedure is to carry out a structural analysis of the structure based on current member geometry and condition of the structure. DSL has in-house resources to carry out every aspect of these work scopes, from survey and engineering through the installation of any replacement parts or enhancement kit that is determined necessary. The same work scope applies if you need to increase your hook load, setback, or other loads/combinations that are outside the original design criteria of the derrick.
DSL is an API 4F licensed company for drilling structures with the qualifications, accreditation, engineering resources, software, and worldwide locations to support your project needs regarding drilling derrick analysis and associated derrick structural engineering.
Upon completion of the work scope, you will be in possession of all the relevant certification and associated documentation that validates the operational capacity of your API structure.
