      <title>DEVELOPMENT OF A TOW CAPABILITY FOR THE HH-3F HELICOPTER</title>
      <link>https://trid.trb.org/View/42584</link>
      <description><![CDATA[An extensive evaluation was conducted to determine the capability of the HH-3F helicopter to tow the Fast Surface Delivery (FSD) System. The aircraft flying qualities, aircraft response to simulated emergencies, Automatic Flight Control System, and the simplicity and reliability of the tow equipment enhance the ability of the HH-3F helicopter to fulfill the requirements of the U.S. Coast Guard tow mission. Mission limitations are imposed by the low power margin at high gross weights in the low speed tow regime. Inefficient transmission oil cooler operation limits the amount of time allowed in a downwind tow condition. Further testing is recommended to determine pilot fatigue limitations due to unusual aircraft attitudes during tow operations. Also, additional testing is necessary to determine the effects of higher sea states on the aircraft and FSD combination. Within the scope of this evaluation, the HH-3F helicopter and FSD tow combination is satisfactory for the U.S. Coast Guard operational tow mission.]]></description>

      <title>COAST GUARD EVALUATION OF A WAVE ACTIVATED TURBINE GENERATOR BUOY</title>
      <link>https://trid.trb.org/View/143774</link>
      <description><![CDATA[Wave activated turbine generator buoys were tested at Chesapeake Light (14 miles off Cape Henry, Virginia) and in Boston Harbor. The buoys were instrumented to record cumulative power generated and later modified to record sea state as well as other variables pertinent to turbine operation. Results are presented as long-term power generation, power generation as a function of wave height and period, and transfer functions from spectral analysis of data. (Author)]]></description>

      <title>RADAR AND TUCKER WAVEMETER DATA FROM SEA-LAND MCLEAN - VOYAGE 60 (SL-7-21)</title>
      <link>https://trid.trb.org/View/162505</link>
      <description><![CDATA[So that more precise correlations between full scale observations and analytical and model results could be carried out, one of the objectives of the instrumentation program for the SL-7 class container ships was the provision of recording the wave environment.  To this end, two wave meter systems were installed on the S.S. SEA-LAND McLEAN. Raw data was collected from both systems during the second (1973-1974) and third (1974-1975) winter data collecting seasons. It was the purpose of the present work to reduce this raw data, to develop and implement such corrections as were found necessary and feasible, and to correlate and evaluate the final results from the two wave meters. In carrying out this work it was necessary to at least partly reduce several other channels of recorded data, so that, as a by-product, reduced results were also obtained for midship bending stresses, roll, pitch, and two components of acceleration on the ship's bridge.]]></description>

      <title>TANKER BERTHING EVALUATION FULL-SCALE TRIAL RESULTS EMPLOYING THE MSC TANKER YUKON AND A ROTATABLE, RIGHT-ANGLE DRIVE TUGBOAT TINA</title>
      <link>https://trid.trb.org/View/143563</link>
      <description><![CDATA[The David W. Taylor Naval Ship Research and Development Center (DTNSRDC) conducted full-scale trials to gather tug/ship interaction forces developed by an advanced, right-angle drive tugboat (TINA) in maneuvering a tanker (YUKON). The overall intent of these trials is to modify the 'tug effect' subroutine at the Maritime Administration Computer Aided Operations Research Facility (CAORF) at Kings Point, New York by developing, from the full-scale trial data presented herein, percentage factors to discount nominal tug thrust under appropriate situations to approximate the effect of flow conditions around the tug propellers created by motion of the tug, or the position of the tug relative to the tanker.]]></description>

      <title>COMPARATIVE SHIP PERFORMANCE SEA TRIALS FOR THE U.S. COAST GUARD CUTTERS MELLON AND CAPE CORWIN AND THE U.S. NAVY SMALL WATERPLANE AREA TWIN HULL SHIP KAIMALINO</title>
      <link>https://trid.trb.org/View/150926</link>
      <description><![CDATA[During April and May 1978, this Center participated in a set of comparative ship performance trials conducted jointly by the United States Navy (USN) and the U.S. Coast Guard (CG). These trials consisted of the side-by-side operation of the 378-foot CG Cutter MELLON, the 95-foot CG Cutter CAPE CORWIN, and the 89-foot USN small waterplane area twin hull (SWATH) ship KAIMALINO in seas of opportunity for three 8-hour periods at different relative headings to the sea, with an additional continuous 36-hour trial period involving only the CAPE CORWIN and the KAIMALINO. Within this trial period there were five 8-hour periods wherein six test subjects per vessel were monitored for physiology and affective state while undergoing a series of human factors experiments designed to evaluate the effects of vessel habitability and ship-motion-related degradation on the task performance of experienced sailors. The suitability of the SWATH for typical Coast Guard missions currently performed by conventional surface ships can be addressed through interpretation of these trial results. This report documents trial details and recording procedures; identifies measurements recorded by DTNSRDC; briefly describes the analysis techniques used; presents results of those analyses; and comments on these results, drawing conclusions as appropriate. This material complements reports currently under preparation by the Coast Guard which primarily address the human factors aspects of this trial.]]></description>

      <title>SURFACE OIL DISPLACEMENT BY U.S. COAST GUARD 82-FOOT CUTTERS</title>
      <link>https://trid.trb.org/View/144087</link>
      <description><![CDATA[The U. S. Navy, in cooperation with the U. S. Coast Guard, is conducting design and feasibility studies for a portable oil sorbent spreader and retriever for use aboard military and commercial vessels-of-opportunity during oil spill clean up operations. As part of this program, the U. S. Navy's Civil Engineering Laboratory (CEL), Port Hueneme, California contracted with the Geography Remote Sensing Unit (GRSU), University of California, Santa Barbara to provide field support and data analysis services in conjunction with sea tests to determine the effects of vessels on surface oil slicks. A total of four sea truth data acquisition cruises were conducted through natural oil seeps in the Santa Barbara Channel, California between December 1977 and February 1978. Coast Guard 82-foot patrol boats served as representative vessels of opportunity for the tests. This report describes the data collection program associated with the sea tests and the results of our analysis of field data. (Author)]]></description>

      <title>LOW SPEED SEAKEEPING TRIALS OF THE SSP KAIMALINO</title>
      <link>https://trid.trb.org/View/82952</link>
      <description><![CDATA[Full scale low speed seakeeping trials were conducted on the Stable Semi-submerged Platform (SSP) design designated the SSP Kaimalino, a Small Waterplane Twin Hull (SWATH) with an overall length of 87.8 ft (26.7m). Trials were conducted in a Sea State 5 at various headings at a nominal speed of 5 knots. Measurements were made of craft motions and accelerations, and the seaway. Results are presented in significant value and power spectral form. The results establish the low speed motions of the SSP and illustrate the good seakeeping characteristics inherent in SWATH ship designs. (Author)]]></description>

      <title>THE BARBEY REPORT. AN INVESTIGATION INTO CONTROLLABLE PITCH PROPELLER FAILURES FROM THE STANDPOINT OF FULL-SCALE UNDERWAY PROPELLER MEASUREMENTS</title>
      <link>https://trid.trb.org/View/69535</link>
      <description><![CDATA[This report reviews the previous experience with Controllable Pitch Propellers (CPP). Two ships of the FF-1052 class were fitted out with CPP's for test and evaluation. One of these ships, the USS BARBEY (FF-1088), experienced difficulties followed by catastrophic failure of the CPP mechanism after a relatively short period of operation. As part of an extensive investigation into the general CPP design philosophy with particular reference to the failures experienced on BARBEY, the David W. Taylor Naval Ship Research and Development Center (DTNSRDC) instrumented the CPP mechanism on BARBEY and conducted full-scale drydock, dockside, and underway tests. The results showed that the quantitative and qualitative assumptions made in the structural design and propeller blade loads (especially during maneuvers) were not compatible with reality. More explicitly, the propeller blade palm acts as a nonuniform, nonlinear loading mechanism on the blade bolts. It was found that this mechanism causes excessive loads which lead to fatigue damage in the bolts and crank disk. This was most likely the direct cause of the original bolt failures and, together with geometric design and metallurgical deficiencies, contributed significantly to the crank disk failures.]]></description>

      <title>PERFORMANCE CHARACTERISTICS OF A PAIR OF PROPELLERS FOR THE SEA FOX</title>
      <link>https://trid.trb.org/View/69543</link>
      <description><![CDATA[Two 22 inch Newton Rader type full scale propellers were manufactured and tested for use during full scale trials on the 11 meter "Sea Fox". Open water tests were conducted and cavitating performance characteristics were obtained for these propellers over a range of cavitation numbers corresponding to full scale speeds from 9 to 45 knots. The propeller performance data and a table containing the principal propeller geometry information is presented in this report. (Author)]]></description>
