      <title>DRYDOCK EXTENSION - A 1980 UNDERWATER TECHNOLOGY SURVEY FOR EXTENSION OF TIME BETWEEN DRYDOCKING</title>
      <link>https://trid.trb.org/View/170426</link>
      <description><![CDATA[The results are presented of a feasibility study to extend the time between drydocking of commercial vessels under U.S. Coast Guard jurisdiction. The existing drydock inspection requirements are documented and then compared to underwater technology. It is demonstrated that with trained divers, underwater closed circuit television, and color photography, the Coast Guard inspector can be provided with the visual information he needs. Problems with water turbidity can be alleviated by careful selection of the sea port and matching the camera and light sources. Use of blanking flanges and listing and tipping of a vessel allow for a complete inspection. Underwater preservation, maintenance, and repair are all possible with existing underwater technology.

      <title>STATE-OF-THE-ART SURVEY OF HARDWARE DELIVERY AND DAMAGE INSPECTION METHODS FOR COAST GUARD HAZARDOUS CHEMICAL SPILL RESPONSE</title>
      <link>https://trid.trb.org/View/162819</link>
      <description><![CDATA[This report is a study of methods that might be used by the Coast Guard, in accomplishing three tasks when responding to a hazardous chemical spill originating from a tank vessel or barge in the marine environment. The specific tasks are: (1) Damage inspection of the endangered vessel; (2) Delivery of Coast Guard hazardous chemical patching and plugging devices (e.g., polystyrene foam plug, evacuated foam plug, air/water inflatable bags); and (3) Delivery of a chemical sensor for venting rate measurements, sampling, and analysis for the detection, identification, and quantification of hazardous chemical pollutants. Mission requirements and hardware design goals are established. All possible methods are reviewed and subjected to a weighted factor evaluation. The results of the evaluation indicate the most promising approach is through the application of a Remotely Operated Vehicle (ROV). Detailed information of ROVs is compiled and presented.

      <title>MORPHOLOGICAL ANALYSIS OF UNDERWATER SENSING FOR COAST GUARD APPLICATIONS</title>
      <link>https://trid.trb.org/View/82420</link>
      <description><![CDATA[The purpose of this study was to survey and explore concepts of underwater and water-related sensing systems and determine the technology appropriate for present and anticipated Coast Guard activities. The procedure employed both a literature study and a survey letter to sensor manufacturers and users to obtain a broad base of representative sensor information. The information was cataloged in a computer file using a classification system which included sensor, environment, and object descriptor groups. Selected Coast Guard activities were considered in detail to determine their general sensor requirements. A computer-aided morphological method was used to analyze the required general sensor operating characteristics and concurrently examine the data base to determine the relevance of existing technology. General recommendations were developed for the application of existing technology and for the development of new technology where indicated. (Author)]]></description>

      <title>ULTRASONIC PROCESSOR REDUCES DRILL-CUTTINGS SIZE AND ELIMINATES SUBSEA MOUNDS</title>
      <link>https://trid.trb.org/View/577231</link>
      <description><![CDATA[Drill cuttings size reduction using ultrasonics eliminated a subsea clean-up and significantly reduced the environmental impact in a North Sea drilling project. Reduction in cuttings size allows for a wider areal dispersion when released into the ocean because they are held in suspension longer than larger sizes. Thus, ocean currents carry the smaller cuttings farther away from the well template, leaving a much wider footprint than larger cuttings sizes. This eliminates the pile-up of cuttings that otherwise would contaminate and harm the marine habitat.]]></description>

      <title>MODEL EXPERIMENTS OF THE CONTROL SYSTEM OF THE UNDERWATER MANIPULATOR</title>
      <link>https://trid.trb.org/View/455996</link>
      <description><![CDATA[This paper studies the control system of the underwater manipulator of an underwater vehicle.  The learning feed-forward controller is applied to the hybrid position and force control system of the underwater manipulator.  This control system consists of a feed-forward controller based on an inverse-dynamics model of the controlled system and a feedback controller like a proportional, integral and derivative controller.  This control system is adaptable to the nonlinear dynamics of multi-link manipulator and the change of dynamics both of the manipulator and of the controlled object.  For the learning of the inverse-dynamic model a new method is proposed to hasten the learning speed.  Experiments carried out showed that the new learning method is quick and that the control system is adaptable to the change of dynamics according to the payload.]]></description>

      <title>UNDERWATER INSPECTION OF STEEL OFFSHORE INSTALLATIONS: IMPLEMENTATION OF A NEW APPROACH</title>
      <link>https://trid.trb.org/View/438011</link>
      <description><![CDATA[This report is the outcome of a major joint industry sponsored project initiated by UEG. Its overall aim is to improve the effectiveness of underwater inspection of offshore installations, particularly through the use of a more rational method of planning inspection operations. The heart of this method is that an installation owner should be provided with a level of confidence in the condition of each component of the installation commensurate with the consequences of failure of that component. After an introductory part which outlines this method and sets it in the context of other inspection planning philosophies, major chapters of a second part review and discuss: - types of damage and deterioration - applying the proposed inspection planning methods to existing installations - the management of inspection operations offshore - inspection operations, including inspection methods, cleaning, intervention and monitoring - the assessment of any damage found A final part discusses the adaptation of the proposed planning method to the design of new installations and suggests how attention to detail design of new structures can ease the practical tasks of underwater inspectors in future.

      <title>AN INTEGRATED TOWED FLOWLINE BUNDLE PRODUCTION SYSTEM FOR SUBSEA DEVELOPMENTS</title>
      <link>https://trid.trb.org/View/436805</link>
      <description><![CDATA[The concept of the integrated towed flowline bundle production system (ITFPS) is based on onshore construction and testing of a complete subsea system that consists of flowlines and control lines, as well as facilities for manifolding and, if so appropriate, for drilling and processing. The installation of such a system can be done by a pull or towing technique. The ITFPS is a concept designed for the development of subsea fields such as satellites to existing offshore production facilities, a floating production development whereby the ITFPS can include the riserbase on one end as well as the production manifold on the other end; or for a 'near shore' subsea development that can be remotely operated from an onshore base.]]></description>
