A method of producing a hydrodynamic cavitation fluid injector, hydrodynamic vacuum pump, venturi fluid injector, or similar device in which a special cylindrical insert is combined with a suitable body, such as one of any number of common off-the-shelf or purpose built pipe and tube “tee” fittings. In its various embodiments, the insert has features, geometry, dimensions, and material characteristics suitable to the intended application, and is installed into the body through any of a variety of methods including threads, epoxy, press-fit, barbed press fit, plastic welding, solder, O-ring, bushing, flange, clamp, etc. to produce the complete injector/vacuum pump assembly. While the term hydrodynamic ordinarily applies only to liquid fluids, for the purposes of descriptions and claims of the present invention it should also be taken to include gaseous fluids. The injector/vacuum pump insert concept works just as well with gaseous fluids as with liquid fluids.

An offshore riserless drilling system drills a subsea borehole from a platform and through a cased borehole. The system comprises a lightweight drill string suspending a bottomhole assembly and extending from the platform downwardly through a depth of water into the cased borehole; a first limiter limiting the range of motion of the drill string adjacent the platform; and a second limiter limiting the range of motion of the drill string adjacent the cased borehole. The preferred methods include lowering a bottomhole assembly suspended on a lightweight drill string from a platform through a depth of water; limiting the bend radius of the drill string adjacent the platform; guiding the bottomhole assembly into a cased borehole; limiting the bend radius of the drill string adjacent the cased borehole; maintaining the bottomhole assembly in the cased borehole, and drilling the subsea borehole.

Systems and methods for controlling movement of an elongated member providing communication between a vessel and a subsea unit are provided. The method can include connecting a positively buoyant member to an elongated member at a first location and connecting a negatively buoyant member to the elongated member at a second location, wherein at least a portion of the negatively buoyant member rests on a seabed when the elongated member is in an operational null position.

Disclosed are compliant variable tension risers () to connect deep-water subsea wellheads () to a single floating platform () in wet tree or dry try systems. The variable tension risers () allow several subsea wellheads (), in water depths from 1220 to 3050 meters, at lateral offsets from one-tenth to twice the depth or more, to tie back to a single floating platform (). Also disclosed are methods to counter buoyancy and install variable tension risers using a weighted chain ballast line ().

Disclosed are compliant variable tension risers () to connect deep-water subsea wellheads () to a single floating platform (). The variable tension risers () allow several subsea well-heads (), in water depths from 4,000 to 10,000 feet, at lateral offsets from one-tenth to one-half of the depth, to tie back to a single floating dry tree semi-submersible platform (). Also disclosed are methods to counter buoyancy and install variable tension risers using a weighted chain ballast line ().
