Tender-assisted drilling (TAD) involves the use of tender support vessel (TSV) during the drilling phase of platform development to provide drilling utilities to the platform-mounted drilling package. The TSV provides facilities such as mud mixing, storage, pumping, bulk storage, hotel accommodations, and power. Thus, the platform topsides and jacket weight and size can be smaller and less expensive. The paper discusses the advantages and disadvantages of TAD, then describes the TAD vessel, semisubmersible, platform cost savings, accommodations, drilling and workovers, and field experience.
