Abstract:
The present invention provides an anti-fouling pressure-sensitive adhesive sheet and anti-fouling treatment method capable of preventing peeling from overlapping portions when adjacent anti-fouling pressure-sensitive adhesive sheets are attached by allowing end portions thereof to overlap each other. The anti-fouling pressure-sensitive adhesive sheet of the present invention includes a base material layer; a pressure-sensitive adhesive layer provided on one side of the base material layer; and an anti-fouling layer provided on another side of the basematerial layer, wherein the anti-fouling pressure-sensitive adhesive sheet has, at an end portion thereof, a bonding margin including parts of the base material layer and the pressure-sensitive adhesive layer, the parts extending beyond the anti-fouling layer.
Abstract:
An object is to prevent damage to an inspection object such as a subsea structure, the damage being due to receiving force based on the mass of a cruising body, and to improve the quality of various work, including an inspection of the inspection object. An underwater mobile inspection apparatus 11 is capable of inspecting a subsea pipeline (inspection object) 13 while cruising. The underwater mobile inspection apparatus 11 includes: a cruising body 14 configured to submerge under water and cruise along the inspection object in such a manner as not to come into contact with the subsea pipeline 13; a first movable arm 16 provided on the cruising body 14; an inspection tool unit 17 for use in inspecting the subsea pipeline 13, the inspection tool unit 17 being provided on the first movable arm 16; and a controller configured to, when the cruising body 14 cruises along the subsea pipeline 13 in such a manner as not to come into contact with the subsea pipeline 13, operate the first movable arm 16 to move the inspection tool unit 17, such that a positional relationship of the inspection tool unit 17 with the subsea pipeline 13 becomes a predetermined target positional relationship.

Abstract:
An under-keel inspection system (10) for inspection of vessels (20), e.g. underway toward or away from a harbour or other protected anchorage, comprises a beam (14) configured for being arranged across a navigation corridor (18) at a depth sufficient to allow a vessel to pass above the beam during inspection. The beam has a plurality of individual hull inspection devices (12) mounted thereon, which are distributed over the length of the beam. Each hull inspection device is equipped, at least, with a sonar (24) and is coupled with a deployment mechanism that may individually raise and lower the hull inspection device perpendicular to the axis of the beam in such a way as to adjust the distance between the hull inspection device and the vessel to inspect.
Abstract:
Various rolled or extruded profiles (1c, 1d) with weld locations are used to connect together structural sandwich plate members comprising first and second outer metal plates (21) and an elastomer core (22) bonded to said outer metal plates (21) with sufficient strength to transfer shear forces therebetween.
Abstract:
A method of removing a coating, such as paint, varnish, biological growth or grime, from a surface, the method comprising selecting a suitable particulate solid having a particular size of from 150-250 mm and a fluid carrier to form a spray mixture and spraying the mixture as a jet spray so as to impact and at least partially remove the coating. The hardness of the particulate solid is less than 8.0 on the Moh scale. The pressure applied to the spray mixture to generate the spray is from 3x105 to 1.5¿x?10?6 Nm-2¿. An apparatus comprising a blasting pot (1) and a compressor (2) to generate the spray mixture and propel it from a nozzle (5) is also disclosed. Heating may be applied to the carrier, either prior to or when mixing with the particulate solid.
Abstract:
The present invention relates to an apparatus (10) for performing nonmanual tasks on and adjacent vertical or nearly vertical surfaces. The apparatus (10) is designed so that a portion of the apparatus can traverse the vertical or nearly vertical surfaces of structures (11) which may include obstacles such as window frames or gaps created by window seams, without coming into physical contact with those surfaces. The apparatus (10) includes a bottom control unit (16), a vehicle (12) for traversing the vertical or nearly vertical surfaces, and a top control unit (14). The vehicle (12) is maintained in a near constant spaced relationship to the vertical surfaces by flexible members (35) that connect the vehicle (12) to the top control unit (14) and bottom control unit (16).
Abstract:
The present invention provides an underwater inspection and monitoring apparatus, comprising: at least one sensor (40) configured to function underwater, the at least one sensor being supportable by a diver when in use, wherein each sensor is connected by a transmission line (22) to a remote, out of water, surface positioned processor and controller (30), whereby control signals for the at least one sensor are generated by the controller and signals generated by the at least one sensor are processed by the processor, the signals being passed along the at least one transmission line. This enables the processor and controller to be kept out of water making the sensor(s) easily portable and easy to use thereby reducing the risk of instruments being lost and making the inspection and monitoring process more safe, efficient and cost effective. Further, the values generated by the at least one senor may be displayed on the surface console and to the diver simultaneously and may be stored.
Abstract:
Es wird ein mikroelektronisches Modul (100) zur Reinigung einer Oberfläche angegeben. Das mikroelektronische Modul weist wenigstens einen Spannungswandler (101) zur Umwandlung einer bereitgestellten ersten Spannung (V1) in eine höhere, niedrigere oder identische zweite Spannung (V2) auf. Weiter weist das Modul wenigstens einen Aktuator (102) auf. Der Aktuator weist wenigstens einen Generator (103) zur Erzeugung eines Ionenstroms, eines elektrischen Plasmas, von Oberflächenwellen und/ oder eines elektrostatischen Feldes aus der von dem Spannungswandler bereitgestellten zweiten Spannung auf. Wenigstens der Spannungswandler und der Aktuator sind auf einem gemeinsamen dünnschichtigen flächigen Substrat (104) angeordnet. Mittels des Aktuators erfolgt die wenigstens überwiegende Entfernung wenigstens eines an der Oberfläche haftenden Objekts.
