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

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

ABSTRACT
This specification covers the requirements for the design and construction of a semi-flush, oiltight, and watertight bolted hinged manhole cover assembly for use in deck or bulkheads subjected to lateral pressures such as resulting from vehicle loads or hydrostatic pressure. Not covered by this specification are the design requirements for manhole cover assembly subjected to primary or cyclic loads and certain hazardous cargos. The manhole cover assembly covered by this specification are classified into various types (Types I and II based on size of access opening), grades (Grades 1-3 based on the thickness of the cover plate), and classes (Classes A and B based on surface finish). The assembly shall be comprised of covers, mounting rings, gaskets, studs, washers, hinge assemblies, and nuts. The components shall be manufactured from carbon structural steel (plate for the cover, ring, hinge pad, and hinge blade), steel (round bar for hinge pin), ordinary steel (welded studs), and yellow brass (washers, heavy hex nuts, and cotter pin). The assembly shall be free of splinters, sharp edges, burrs, projections, and weld splatters, and shall have a Class A finish. Pressure and tightness tests shall be performed and shall conform to the requirements specified.
SCOPE
1.1 This specification provides design and construction criteria for a semi-flush, oiltight and watertight bolted hinged manhole cover assembly.  
1.2 The manhole cover assemblies depicted on this specification are 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, studs, washers, hinge assemblies, and nuts.  
1.3 Handles, if required, shall be as specified in the ordering information.  
1.4 Values stated in inch-pound units are to be regarded as standard.  
1.5 This standard is not applicable to certain hazardous cargos. (See 46CFR 153.254 and 46CFR 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.

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.
