Environmental loads and large, heavy drilling risers impose design restrictions on drilling systems installed on deepwater tension leg platforms (TLPs). The use of a full drilling package for deepwater TLPs requires detailed planning, especially in the early conceptual phase. This paper reports that in some cases, the cost involved in full drilling operations from a deepwater TLP may be prohibitively high. For these situations, one way to make the prospect economically attractive is to predrill the wells from a floating vessel and use the TLP only as a wellhead platform. However, the use of a TLP only as a wellhead platform, with no drilling package onboard, introduces a number of disadvantages.
