An oil well rig having a flotatable hull and support legs which are lifted and supported by the floating hull for moving the oil well rig and moved down to engage the sea bottom and jack up or raise the hull above the water at an operating site for drilling or servicing a well or serving an offshore well platform. A water tower has pipes longitudinally mounted by brackets on each side on a beam and is mounted for vertical movement in a well in the hull. An elevator mechanism mounted in the hull is employed to raise and lower the water tower which has guide means fitting a guide portion of the well to provide guided vertical movement of the water tower. When the water tower is lowered, a pump at the bottom of the pipe pumps sea water through the pipe to machinery on the hull to meet the water requirements of the machinery.

LIQUID WATER LOSS REDUCING ADDITIVES FOR CEMENT SLURRIES Jiten Chatterji, Bobby G Brake, John M Tinsley assigned to Halliburton Company Liquid water loss reducing additives for use in cement slurries are provided comprised of aqueous solutions of low molecular weight carboxymethylhydroxyethyl-cellulosepolymers. Methods of using the additives are also provided.
Dominique Michel, Jean G M Martin, Vincent F P Foglia, Francois G Sedillot, Paris, France assigned to Compagnie General pour les Developpements Operationnels des Richness SousMarines C G Doris An osciilatable marine installation comprises a concrete and steel lattice shaft supported by means of a demountable pivot joint on a base fixed to the-sea-bed and including an anti-torque device. The pivot joint is made up of three parts: a casing fixed to the shaft, a part-spherical housing fixed to the base, and a pivot member. The pivot member has an upper part cooperating with the casing, a flange which can be fixed to the casing, and a lower part-spherical part housing which supports a resilient assembly and a bush fixed on the housing. The anti-torque device comprises a universal joint, concentric with the pivot joint. Two opposite pivots of the crosspiece of the universal joint are supported by the lower part of the shaft and the other two pivots by the base. At least two opposite pivots have damping devices and the pivots supported by the base are mounted on supports the height o f which can be adjusted.
OPEN SEA SKIMMER BARGE William Ayers, Ashok K Maheshwary, Peter J Young assigned to Halliburton Company An open sea skimmer barge comprising a hull having a bow, bottom, side walls, stern having a substantially horizontal elongate slot extending across a portion thereof and a deck, a spill suction tunnel, a collection tank, secondary oil separation means and tertiary oil separation means.
