Abstract
A novel guide member and guide member support arrangement for guiding a drill conductor from a deck portion of an offshore platform into the bottom of a body of water is disclosed. The guide member is snugly nestled against and positioned within the guide member support which directly provides lateral and vertical support for the guide member. The guide member has an upper funnel-shaped portion and a lower cylindrical portion. The guide member support comprises the plurality of connected structural members arranged in a plane for defining a support opening for the guide member. The guide member is connected to the guide member support at at least three positions.
