Taking rock samples from a well by means of a special tool — a “core barrel”.

Corn ethanol is ethanol produced from corn biomass and is the main source of ethanol fuel in the United States.

A joint between two elements located approximately at right angles in the form of L.

A shaped seal unit to go around right-angled or compound corners.

A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage.

Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, carbonate or sulfide.

Corrosion engineering is an engineering specialty that applies scientific, technical, engineering skills, and knowledge of natural laws and physical resources to design and implement materials, structures, devices, systems, and procedures to manage corrosion.

- Excessive corrosion – An extent of corrosion that exceeds the allowable corrosion.

The process in which a metal fractures prematurely in a transcrystalline manner under conditions of simultaneous corrosion and cyclic loading at lower stress levels or fewer cycles than would be in the absence of a corrosive environment.

A corrosion inhibitor is a chemical compound that, when added to a liquid or gas, decreases the corrosion rate of a material, typically a metal or an alloy, that comes into contact with the fluid.

A full hard coating or full hard coating supplemented by cathodic protection.

Rate at which the corrosion proceeds. It is the thickness of metal lost during one year, on one side of the surface. It is expressed in mm by year.

Fluids causing damage by coming into contact with living tissues, the vessel or its cargo, when escaped from their containment.

A corrosive substance is one that will damage or destroy other substances with which it comes into contact by means of a chemical reaction.

Having a series of arranged wrinkles or grooves to produce stiffness with a reduction in weight.

A new safety equipment for man overboard retrieval situations. The device allows for both conscious and unconscious casualties to be lifted from the water in a safe horizontal position.

The Coselle CNG System has been developed in cooperation with ABS and DNV to transport compressed natural gas.

Cosmic rays are high-energy protons and atomic nuclei that move through space at nearly the speed of light.

Cost breakdown analysis is a method of cost analysis, which itemizes the cost of a certain product or service into its various components, the so-called cost drivers.

A cost estimate is the approximation of the cost of a program, project, or operation.
