This paper describes the initial phase of a multi-well subsea development using a building block technique. This phase included the setting of the conductors for all 20 wells, manifold piles and pipeline bases and the drilling of 15 wells to various stages of completion. Offshore operations were conducted in batches to maximize efficiencies and economies of scale. The emphasis of this paper is on the jetting operation of the conductors and the positioning techniques used to meet the requirements of the later phases of the building block process.
