Standard Specification for Manhole Cover Assembly, Bolted, Semi-Flush, Oiltight and Watertight

Standard Specification for Manhole Cover Assembly, Bolted, Semi-Flush, Oiltight and Watertight

ABSTRACT
This specification provides the design and construction criteria for a semi-flush bolted oiltight and watertight manhole cover assemblies that are subjected to lateral pressures such as resulting from vehicle loads or hydrostatic pressures, and used in decks or bulkheads requiring manhole covers that are not required to be completely flush. Manhole cover assemblies shall be complete with covers, mounting rings, gaskets, welded studs, washers, and nuts. This specification does not address certain hazardous cargos, as well as the design of the manhole cover assembly for primary or cyclic loads.
SCOPE
1.1 This specification provides design and construction criteria for a semi-flush, oiltight, and watertight bolted manhole cover assembly.  
1.2 The manhole cover assembly depicted in this specification is for use in decks or bulkheads requiring oiltight and watertight covers that are not required to be completely flush. Manhole cover assemblies shall be complete with covers, mounting rings, gaskets, welded studs, washers, and nuts.  
1.3 Handles, if required, shall be as specified in the ordering information.  
1.4 The values stated in inch pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This specification is not applicable to certain hazardous cargos (see Section 46 CFR 153.254 and 46 CFR 154.340).  
1.6 This specification provides design and construction for manhole cover assemblies subjected to lateral pressures such as resulting from vehicle loads or hydrostatic pressures. Where manhole cover assemblies are subjected to primary or cyclic loads, other reinforcement or construction criteria may be necessary to integrate the manhole assembly with the required structural reinforcement for openings in decks or bulkheads. Design of the manhole cover assembly for primary or cyclic loads is beyond the scope of this specification.

ASTM F3040/F3040M-13(2023)(Test Method)
Standard Test Method for Mechanical Static Load Testing of Non-Structural Marine Joiner Bulkheads

SIGNIFICANCE AND USE
4.1 The test method provides information regarding the behavior of a non-structural A, B, or C-Class bulkhead panel system under a static load. Test data for load, moment and deformation is measured.  
4.2 Static load test of non-structural marine joiner panel systems provide a standard method of obtaining data for research and development, quality control, acceptance or rejection under specifications, and special purposes. The tests cannot be considered significant for engineering design in applications differing widely from the loading type and magnitude of the standard test. Such applications shall require additional tests.
SCOPE
1.1 This test method covers a procedure for evaluating the strength of non structural marine joiner of A, B, and C-Class bulkhead and liner systems. A, B, and C-Class bulkheads are defined and discussed in 2.1.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Selection of Structural Details for Ship Construction

ABSTRACT
This guide provides a recommended list of selected ship structure details for use in ship construction. Structural details which have failed in service and are not recommended for use in ship construction are included as well. This guide is intended to convey the lessons learned on different configurations of ship structure details, not the dimensions, thickness, or construction methods which would result from structural calculations. Details are shown for the ten families of structural details, which are: beam brackets, clearance cut-outs, gunwale connections, miscellaneous cut-outs, non-tight collars, panel stiffeners, stanchion ends, stiffener ends, tight collars, and tripping brackets. Evaluation of details is based on in-service experience as described in "Design Guide for Structural Details". Data for over 400 details is summarized and rated by observed relative successful performance. Each of the ten families of details includes configurations with no signs of failures. The details without failures within each family group are shown in descending order of numbers observed. Those details with failures are shown in ascending order of failures (percentages are indicated for each). Thus the first detail shown in each family group has the best observed service performance and is most highly recommended while the last has the highest failure rate and therefore least desirable. The details provide guidance in the selection of structural detail configurations in future design and repair of such details.
SCOPE
1.1 This guide provides a recommended list of selected ship structure details for use in ship construction.  
1.2 Structural details which have failed in service and are not recommended for use in ship construction are included as well.  
1.3 This guide is intended to convey the lessons learned on different configurations of ship structure details, not the dimensions, thickness, or construction methods which would result from structural calculations.4  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Portable Intermediate Flush Deck Stanchion

ABSTRACT
This specification covers the design, construction, and installation details of two-course (Type I) and three-course (Type II) portable intermediate flush deck stanchions that are used on interior and exterior decks to provide temporary protection and minimize the danger of personnel falling overboard or to a lower level in the ship in areas where the installation of a fixed system would interfere with vessel operations. This specification does not include the requirements for the chain or wire rope lines to be supported by the stanchion. The stanchions shall be free of weld spatters, slag splinters, sharp edges, burrs, projections, and other defects hazardous to personnel, and the deck sockets shall be hammer tested for soundness and strength.
SCOPE
1.1 This specification covers the design, construction, and installation of intermediate portable flush deck stanchions. Intermediate stanchion is defined as any stanchion that is not an end or corner stanchion.  
1.2 Stanchions shall be used on interior and exterior decks, to provide temporary protection to minimize the danger of personnel falling overboard or to a lower level in the ship in areas where the installation of a fixed system would interfere with vessel operations.  
1.3 Stanchions may be used with 3/8-in. (9.5-mm) galvanized close link chain or wire rope lifelines 9/16-in. (14-mm) top course, 7/16-in. (11-mm) lower courses.  
1.4 This specification covers only the stanchions and does not cover requirements for the chain or wire rope lines to be supported by the stanchion.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
