Glossary of Marine Terms
R
raised rake
the rake of a barge which has sheer.
reachrod
a steel rod which connects an above deck valve handle to a below deck valve.
reduction of area
the percentage difference between the original cross sectional area and that of the smallest area at the point of rupture. the percentage figure can be considered a measurement of ductility.
registered
pertaining to certain vessel data calculated under specific rules and officially documented, such as registered length.
remove or removal
as defined by section 311(a)(8) of the CWA, refers to containment and removal of oil or hazardous substances from the water and shorelines or the taking of such other actions as may be necessary to minimize or mitigate damage to the public health or welfare (including, but not limited to, fish, shellfish, wildlife, public and private property, and shorelines and beaches) or to the environment. For the purpose of the NCP, the term also includes monitoring of action to remove a discharge.
removal costs
as defined by section 1001 of the OPA means the costs of removal that are incurred after a discharge of oil has occurred, or in any case in which there is a substantial threat of a discharge of oil the costs to prevent, minimize, or mitigate oil pollution from such an incident.
residual stress
macroscopic stresses that are set up within a metal as the result of nonuniform plastic deformation or thermal gradients. stresses of this nature are caused by cold working or by drastic gradients of temperature from quenching or welding.
residuals
elements present in an alloy in small quantities, but not added intentionally.
resilience
the tendency of a material to return to its original shape after the removal of a stress that has produced elastic strain.
Responsible Carrier Program - (RCP)
A vessel safety management program developed by the maritime industry through the American Waterways Operators and designed as a framework for continuously improving the industry’s safety performance. AWO members use the RCP as a guide in developing company-specific safety and environmental programs that are tailored to the unique operational environments found in the barge and towing industry. The program complements and builds upon existing government regulations, requiring company safety standards that exceed those required by federal law or regulation.
responsible party
as defined by section 1001 of the OPA means the following:
- Vessels - In the case of a vessel, any person owning, operating, or demise chartering the vessel.
- Onshore Facilities - In the case of an onshore facility (other than a pipeline), any person owning or operating the facility, except a federal agency, state, municipality, commission, or political subdivision of a state, or any interstate body, that as the owner transfers possession and right to use the property to another person by lease, assignment, or permit.
- Offshore Facilities - In the case of an offshore facility (other than a pipeline or a deepwater port licensed under the Deepwater Port Act of 1974 (33 U.S.C. 1501 et seq.)), the lessee or permittee of the area in which the facility is located or the holder of a right of use and easement granted under applicable state law or the Outer Continental Shelf Lands Act (43 U.S.C. 1301-1356) for the area in which the facility is located (if the holder is a different person than the lessee or permittee), except a federal agency, state, municipality, commission, or political subdivision of a state, or any interstate body, that as owner transfers possession and right to use the property to another person by lease, assignment, or permit.
- Deepwater Ports - In the case of a deepwater port licensed under the Deepwater Port Act of 1974 (33 U.S.C. 1501-1524), the licensee.
- Pipelines - In the case of a pipeline, any person owning or operating the pipeline.
- Abandonment - In the case of an abandoned vessel, onshore facility, deepwater port, pipeline, or offshore facility, the person who would have been responsible parties immediately prior to the abandonment of the vessel or facility.
rimmed steel
low-carbon steel in which incomplete deoxidation permits the metal to remain liquid at the top of the ingot, resulting in the formation of a bottom and side rim of relatively pure iron of considerable thickness. steel products such as sheets produced from this type of ingot will have a very good surface quality free of surface defects.
rockwell hardness (test)
see hardness tests.
rolled edges
finished edges, the final contours of which are produced by side or edging rolls. the edge contours meet commonly used are square corners, rounded corners and a rounded edge.
rollinq
a term applied to the operation of shaping and reducing metal in thickness by pressing it between rolls which compress, shape and lengthen it following the roll pattern. steel is either hot rolled or cold rolled depending upon the product being manufactured,
rolling direction
the direction in which the steel product is rolled perpendicular to the axes of the rolls during rolling.
rolling mills
equipment used for rolling down metal to a smaller size or to a given shape employing sets of rolls the contours of which determine or fashion the product into numerous intermediate and final shapes, e.g., blooms, slabs, rails, bars, rods, sections, plates, sheets and strip.
rubrail
a protective railing on the hull of a vessel which is used for fendering.
Rules of the Road
a code governing vessels as to the lights to be carried, the signals to be made, and their safe and proper navigation in order to avoid collisions. Statutes of the United States provide varying regulations for two areas of navigation. These regulations are known as Inland Navigation Rules and International Navigation Rules.
running lights
those lights required to be shown at night aboard a vessel or a tow while underway.
rust
a corrosion product consisting of hydrated oxides of iron. this term is only applied to ferrous alloys.
