Abstract: The invention provides a separator for the removal of solids from a drilling liquid, the separator comprising a tube settler (4) through which the drilling liquid can flow and beneath which a particle collection container is arranged for collecting solids separated from the liquid in the tube settler, wherein the solids collection container is a transportable container that is separate or separable from the tube settler. The invention further provides a process for the removal of solids from a drilling liquid using a separator, in which process a drilling liquid comprising solids is set to flow through a tube settler in order to allow the solids to settle out, thereby obtaining a solids depleted drilling liquid and an accumulation of solids. The invention also provides for the use of a separator comprising a tube settler to remove solids from a drilling liquid.

Abstract: A production riser that provides the benefits of a slug catcher, riser based gas lift, and multiphase meter in a single device and is suited to both shallow and deep-water oil/gas field developments. The riser is formed from a pipe within a pipe. The inner pipe provides the path for the production fluids. Perforations are provided near the base and top of the inner pipe. The top of the annulus between the pipes is closed and is in fluid communication with a gas supply/compression system via an isolation control valve/choke. The bottom of the annulus is closed. Three sets of pressure and temperature transducer transmitters are installed at the top, center, and base of the riser through the outer pipe wall.

Abstract: A subsea raw water injector including a pump which is connected to an injection string and a filter connected to an inlet of the pump to remove particulates from the surrounding sea water. The filter is in the form of an inclined tube settler disposed such that particulates separated from sea water flowing through it are discharged to the seabed.
