Last Summer as a board member of a youth sports complex on a public park the State of Louisiana bidding requirements limited the youth association to only 3 contractors to build a new concession stand. All the engineered drawings were up to all current codes. Of the 3 bids received the lowest bid was $242,000. As a lessee of the park we were able to skirt the rules and had it build by a private contractor as per the bid specs for $68,000. That is government waste.

More than likely the shears will cut the riser to reduce sprung weight so the DWS can be used to complete the cut. We do this on hurricane damaged intervention wells all the time it is sometimes a necessary step

The DWS's biggest problem is twofold the first being the weight or the riser closing the kerf and the second being the loose drill pipe inside the riser. as the wire passes and tries to cut the dp it moves causing wire breakage in addition to the binding issue that is why the saw is rotated if possible. This type of operation is done everyday in intervention both dive and ROV assisted for the downed platform segment. There is another low profile split frame cutter available to make the smooth cut on the riser followed by a DWS cut or split frame cut on the dp. Its called wedding caking the well and is very successful but not easy. Afterwards inflatable subsea valves can be installed to control the flow. The shear can also work but the valve will not be able to be installed but an open riser system can still capture most of the flow. These systems have been in existance since Hurrican Ivan and widely used post Katrine/Rita, but the major risk has always been the potential for increased flow rates if any other part of the operation fails

Build the dome, get it prepared then use a ROV to cut the riser with either a subsea shear or DWS thus allowing a greater oil flow that will cause formaion breakdown and a probable bridge to happen. Presently the restriction of the bend riser is acting as a choke and allowing "production" to continue. The well needs to be flowed hard to collapse the formation. The risk is increased flow therefore the dome needs to be ready

As a season ticket holder for both and having been at both LSU Championship games the Saints game was just incredible. Just never felt LSU was at an Aints level to come back from, even during Hallman, etc.
