Abstract: A building energy analysis system includes a building component library configured to store a plurality of building components, a modeling tool configured to access the building component library and create a building model of a building under analysis using building spatial data and using selected building components of the plurality of building components stored in the building component library, a building analysis engine configured to operate the building model and generate a baseline energy model of the building under analysis and further configured to apply one or more energy conservation measures to the baseline energy model in order to generate one or more corresponding optimized energy models, and a recommendation tool configured to assess the one or more optimized energy models against the baseline energy model and generate recommendations for substitute building components or modifications.

Abstract: As shown a carrier module (2) includes a magazine (9) having five chambers (10) each adapted to receive a pipeline pig, rotatably mounted on a blind hub (8) attached to a frame (7). A hanging eye 14 allows the module to be lowered to an undersea location where, guided by a ROV via a grab handle, its frame member (16) is received by guides (17) of a launcher module (1). The magazine passes through a large connector (4) which engages the blind hub. The ROV operates a bucket drive (22) causing the connector to engage the blind hub in sealing fashion thus enclosing the magazine in a launch chamber (3). A hydraulic ram (11) indexes the magazine to select a chamber from which a pig is to be launched or an empty chamber to receive a pig. Indexing is achieved by a roller on the free end of the ram shaft engaging in a cusped track (26) on the magazine. A pressure connection (12) for launching fluid goes through the center of the magazine, through the blind hub and back into a selected chamber.

Abstract: A plug plugs into a ROV drive bucket limiting rotation of a drive shaft therein to say 15° and reducing the build-up of marine growth in the bucket. As shown it includes a polyethylene body (which may be made in two parts 12, 13) housing a metal socket 11 mounted for limited angular orientation therein. The socket has a twenty four point aperture or recess (22) which fits over a squared end of a drive shaft 10 at various angles orientation. The socket has external splines (20) which fit loosely in wide internal grooves (21) in the body and self-orientates within the body when the body is plugged into the bucket. The plug has a pair of diametrically opposite dogs (4) which engage in slots (5), included in flanges on conventional buckets.

Abstract: A subsea hanging device comprises a hanging frame 1 adapted to support an assembly (such as a gooseneck 3 and a subsea connector 4 being used to attach a heavy pipe 7 to a pipe hub 11 on the seabed), a hanging eye 8 which slides on said frame when a shaft 10 threaded through it is axially rotated, and a ROV drive bucket 12 attached to one end of the shaft. A guide funnel 13, 16 pivoted to the frame and adapted to fit over a guide post 17 on the seabed actuates a pointer 15 which indicates on a scale 14 whether the hanging angle needs adjustment to enable the connector 4 to be engaged with the hub 11.

Abstract: A leadscrew has first and second housing portions—which slide telescopically together. A shaft having an externally threaded portion screws into a complimentary internal threaded portion in the first housing portion, the shaft extending out of the second housing portion at a point where a fluid tight seal is provided_between the shaft and the other of the housings and allows rotation during a screwing action. The second housing includes a flanged end to which a ROV drive bucket is bolted. The shaft has a squared end so that it can be rotated relative to the bucket by the ROV. O-rings provide fluid tight seals between the two housing portions, between the flanged end and bucket, and between the shaft and bucket. A deep sea version incorporating oil bath the pressure of which is equalised to that of the surrounding sea so that O-rings do not have to withstand large pressure differences.

Abstract: A disposable test device consists of a first portion 2 having a fluid application port 5 to which a sample of fluid can be applied, and a handle portion 3 hingedly attached to the first portion 2 at a hinge portion 4 and which normally lies in the plane of the first portion. In use the device is held by the handle portion 3 and the first portion inserted into a measuring instrument. The handle is then deflected downwardly e.g. by the finger of a person to supply a drop of fluid to the port 5.

Abstract: A quick release pipeline clamp comprises at least two clamp segments 2 clamping two pipeline hubs together, a holding arrangement such as stud and nuts arrangements 15, 17 for holding together ends of adjacent clamp segments so that they form a clamping ring and a hydraulically or electrically actuable arrangement such as quick release nuts 15 for causing said holding arrangement to release its hold. The clamp segments have notched edges to make them more flexible and are elastically flexed around the hubs when held in place. Springs 10, 11 further aid separation when the hold is released.

Abstract: A method of forming a low AC loss, fully transposed cabled superconductor from multiple superconducting subconductors cut in a serpentine form from a wider superconducting tape is disclosed. By assembling pre-cut subconductor tapes a cable with a short transposition pitch length can be formed without excessive in-plane or out-of-plane deformation of the tape which could otherwise cause degradation of its superconducting performance. The transposition may be in either Roebel bar or Rutherford cable geometry.

Abstract: A method of processing an oxide superconductor or a precursor thereto contained within an outer cladding or a matrix of an inert metal to form a metal-clad HTS conductor or precursor conductor, includes applying a formulation to the exterior of the conductor including a diffusion bond-inhibiting agent comprising predominantly calcium sulphate, potassium sulphate, sodium sulphate, lithium sulphate, or a combination thereof, typically evaporating the carrier where a liquid carrier is used, to leave a coating of the diffusion bond-inhibiting agent on the exterior of the metal-clad HTS conductor, and shaping the coated conductor so that portions thereof come into contact with one another, by coiling or spooling the conductor for example, and heat treating the conductor. The diffusion bond-inhibiting coating prevents bonding together of the conductor coils or layers during the heat treatment.
