This book was released on 1981 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nondestructive ultrasonic testing and inspection of a sampling of piles in the piers which make up the Deperming Facility at the U.S. Naval Station, Norfolk, Virginia, was carried out. This inspection has shown that on an overall basis the piles are in good condition, however, evidence of both mechanical and biological deterioration was found. The objective of the underwater facility assessment was to assess the physical condition and repairability of the structural members supporting the Deperming Facility. After a Level I 'swim by' of the entire facility, a Level II inspection procedure was carried out to insure the acquisition of sufficiently detailed data related to the internal structural integrity of each pile inspected as to enable determination to be made of the overall bearing capacity and lateral stability of the pier. The data provided is sufficiently detailed to facilitate comparisons with subsequent periodic inspections for purposes of determining progressive deterioration with time.

This book was released on 1980 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the underwater facilities assessments was to provide a generalized structural report and assessment of the principal berthing facility at that activity. That facility is the R3-Fleet Weapons Pier (Wharf) which is the only facility used to load and unload ammunition to and from ships and lighters. The inspection was limited in scope to a Level I investigation using visual and/or tactile means of examination, providing still photographic documentation where feasible. The inspection objective was to provide a general assessment of the structure's physical condition documenting any mechanical, biological, or corrosion damage, with emphasis on any advanced stages of deterioration. Because of the huge amount of piles in this structure, over 4600, a random sampling technique was primarily employed to select and inspect about ten percent of the piles, with heavier emphasis on the older sections of the wharf.

Book excerpt: The objective of the underwater facility assessments conducted at the U.S. Naval Station in Charleston, South Carolina is to provide a generalized structural condition report of designated facilities within the activity. These facilities are Piers KILO, LIMA, MIKE, NOVEMBER, PAPA, QUEBEC, ROMEO, SIERRA, TANGO and UNIFORM. Each facility was inspected by a team of engineer/divers using a combination of visual/tactile and ultrasonic techniques. Critical elements were photo-documented. All piers appear to be in good to excellent condition. No structural anomalies were noted to cause these piers to be downgraded. Generally cracking and spalling of the concrete piles and minor corrosion of the steel pipe piles were the only deterioration observed. No repairs are required on Piers MIKE, NOVEMBER, TANGO and UNIFORM. The remaining piers will need some repair work. Most of the repair work consists of filling cracks greater than 1/32 in. wide and spalled areas deeper than 1 in. with an epoxy grout. These repairs will retard any further deterioration.

This book was released on 1985 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this inspection was to generate a baseline underwater condition survey of Fuel Wharf 128 at the Naval Air Station, New Orleans, Louisiana. Underwater, the pier was in very good condition. No significant deterioration was detected at any piles or connecting hardware. Some submerged horizontal bracing exhibited a softened condition but not general or severe weakness. Above the waterline, fungal decay was present in numerous locations but the overall structural integrity was not significantly impaired, considering the heavy construction and relatively light loading conditions. Recommended maintenance includes replacement of missing fender members and replacement of approximately 30% of the timber deck. Areas revealed during deck replacement should be examined for hidden decay, and moisture traps should be omitted. Other deteriorated framing members (bracing, caps, and stringers) should be spliced or replaced. Top rot in timber piles should be treated to prevent further deterioration and reinforce weakened upper connections. (Author).

This book was released on 1980 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lima Quay Wall Inspection Summary: The quay wall is constructed of concrete sheet piles, and consists of 3400 lineal feet in addition to the east end. The inspection was referenced to NAVFAC drawing 1343552. The quay wall is in good condition. Heavy marine growth approximately three inches thick was evident from the mud line to the low water mark throughout the length of the wall. (Marine growth consisted primarily of barnacles, mussels and scallops.) Fill material was washing out behind the wall in several noted locations. J-K Pier: Half of the piles on J-K pier were spot inspected (at least four places on each) for a total of 300 piles. Spot inspection was required due to heavy marine growth on the piles. Of the 300 piles inspected 168 have sustained minor to moderate damage. The pier is still considered serviceable but requires major work soon to remain serviceable. The minor damage consisted of small cracks and the moderate damage from cracks 1/2 to 3/4 inch deep and up to 20 feet long. Upon cleaning the piles bankia and torpedos were often present. Age and marine growth have caused spalling and generally softened the concrete. A more thorough inspection would require extensive cleaning. Under the pier, above the waterling were several areas with exposed rebar. Improper preparation of the area to be repaired is a probable cause of the extensive spalling of these ganite repairs. NAVFAC drawing numbers 6003915 and 6003918 germane. Photos showing some of the damage are attached as enclosure (3).

This book was released on 1984 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: An underwater facilities inspection was made of certain facilities at the North Island Naval Air Station, San Diego, California during the period July 20 to August 25, 1984. The assessed facilities were: The Old Air Station Bulkhead, The Carrier Quay Wall or Bulkhead, Pier Bravo, and Pier J/K. A condition of moderate to severe sulphate deterioration of the concrete was found in the piling to such an extent that is is recommended that the pier live load be restricted to 100 psf (pounds per square foot) and truck cranes in excess of 15 tons be prohibited. The pier is adequately supported against earthquake forces (as defined in NavFac P-355) applied perpendicular to its principal axis. However, the piles would not be expected to support the pier in the event of earthquake forces applied parallel to the principal axis.
