Abstract: A simple, easily manipulated remote fluid transfer system comprising a pump, grout pipe string, a manipulation device, guide sleeve, and a remote video display device.

Abstract: An improved grouting method and arrangement using aqueous solutions of alkali silicate materials confined between a pair of pile seal assemblies in sealing the annular space formed between either a jacket leg or pile sleeve and a pile driven therethrough or similar annular space of an offshore platform to support a column of grout thereon so that the annular space may ultimately be filled with grouting material.

Abstract: A method of grouting using aqueous solutions of alkali silicate materials in sealing the annular space formed between either a jacket leg or pile sleeve and a pile driven therethrough of an offshore platform, or other similar annular space, to support a column of grout thereon.

Abstract: An inflatable packer and method for sealing the annulus between an outer member and a pile driven therethrough. The inflatable packer comprises a packer housing, first and second guide rings secured within the packer housing, and an inflatable packer member having its ends secured from axial movement within the packer housing by the first and second guide rings. The method of sealing an annulus between an outer member and a pile driven therethrough comprises the steps of sealing the annulus at a first location, injecting gas into the annulus to expel any material contained within the annulus, sealing the annulus at a second location which is free of material, venting the annulus between the first location and second location while maintaining the annulus free of any material, and injecting grouting material into the annulus between the first location and second location.

Abstract: A grout distribution system for grouting the interior of a piling driven through a jacket leg of a marine platform or grouting the interior of a similar cylindrical structure.

Abstract: A retrievable plug for sealing a jacket leg of an offshore platform or similar cylindrical member. The plug comprises a plug body and upper and lower plug body retaining means which restrain the plug body from movement within the jacket leg or similar cylindrical member.

Abstract: A removable plug for the J-tube of an offshore platform or marine structure comprising a plug housing, plug body releasably retained with the plug housing, and shear type threaded fastening means retaining the plug body within the plug housing. The plug body may comprise a buoyant plug body to assist in the retrieval of the plug body after the removal thereof from the plug housing.

Abstract: Sleeve valve for a tank having an opening therein.

Abstract: A system for inflating packers installed in offshore platforms and grouting the annuli between the piles and either the jacket legs and/or pile sleeves utilizing a separate inflation line system for the packers and a separate grouting line system for grouting the annuli.

Abstract: An insertion type cementing baffle comprising a baffle housing and insertion type cementing baffle member.

Abstract: A retrievable plug for sealing a jacket leg of an offshore platform or similar cylindrical member. The plug comprises a plug body and upper and lower plug body retaining means which restrain the plug body from movement within the jacket leg or similar cylindrical member.

Abstract: A reusable plug for sealing the conductor pipe of offshore platforms comprising a cylindrical housing, central body member and pressure equalization means.

Abstract: A pile wiper seal assembly for sealing the annulus between either a jacket leg or pile sleeve and a pile inserted therethrough of a marine platform, the pile wiper seal assembly comprising annular seal member means, upper end shoe means secured to the inner surface of either the jacket leg or pile sleeve having a recess receiving therein the upper portion of the annular seal member means and lower end shoe means secured to the inner surface of either the jacket leg or pile sleeve having a recess receiving therein the lower portion of the annular seal member means whereby the upper end shoe means and lower end shoe means retain the annulus seal member means in either the jacket leg or pile sleeve.

Abstract: A diaphragm for closing the bore of a tubular piling guide member and/or supporting leg member of a marine platform or similar structure, the diaphragm comprising reinforced elastic material bonded to a plurality of reinforcing members in the periphery of the diaphragm with the diaphragm being positively secured to the guide member and/or leg of the platform by means of two flat annular plates which have fasteners retaining the diaphragm therebetween via holes therein.

Abstract: A breech block connector for use in securing wash pipe sections together comprising sleeve means, pin means, box assembly means and locking means.

Abstract: A method and apparatus for inflating a plurality of packers installed in off-shore platforms and grouting the annuli between the piles and pile sleeves thereon utilizing a single line and a control valve system for inflating the plurality of packers and grouting the annuli between the pile and pile sleeves.

Abstract: A method is disclosed for the cementing of casing in a well. The method involves lowering the casing into the wellbore, installing a device on a conduit and thereafter lowering the installed device and conduit to a predetermined position within the casing. The device is then actuated and fluid pressure is applied to the device to interlock the device with either the casing or an adapter previously inserted in the casing. Continued fluid pressure distends a seal member to isolate two regions of the casing. A cementing operation is then performed followed by closure of the device. Preferably, the conduit may then be retrieved for reuse.A device is disclosed for cementing a casing within a wellbore. The device includes a body for occupying a substantial portion of the interior of a region of the casing. The body is connectable to a conduit thereabove and has an external hydraulic seal to pack off the casing.
