Operators, types contractors

A low-risk pipeline is one that is transporting benign materials, such as drinking water and/or is located in a remote environment. Operators and contractors are well experienced in the design, construction, and operation of this type of pipeline.

This type of contract requires the operator to pay a fixed amount to the contractor upon completion of the well, while the contractor furnishes all the material and labour and handles the drilling operations independently. The difficulty with this approach Is to ensure that a quality well Is delivered to the company since the drilling contractor will want to drill as quickly and cheaply as possible. The contractor therefore should guarantee an agreed measurable quality standard for each well. The guarantee should specify remedial actions which will be implemented should a substandard well be delivered. 

As the name implies the company basically rents the rig and crew on a per day basis. Usually the oil company also manages the drilling operation and has full control over the drilling process. This type of contract actually encourages the contractor to spend as much time as acceptable on location . With increased cost consciousness, day rate contracts have become less favoured by most oil companies. 

For the three sinks, the laboratory operator suggested standard enamel sinks. The more expensive epoxy sinks, however, were chosen by the engineering firm because of their high resistance to chemicals. The fact that the city had very strict regulations with regard to discharge of chemicals did not seem to alter their recommendation. The plumbing contractor presented several types of sink traps, from which the laboratory operator picked the one he felt was most easily serviced. 

The Instrumentation and Control Fundamentals Handbook was developed to assist nuclear facility operating contractors provide operators, maintenance personnel, and the technical staff with the necessary fundamentals training to ensure a basic understanding of instrumentation and control systems. The handbook includes information on temperature, pressure, flow, and level detection systems position indication systems process control systems and radiation detection principles. This information will provide personnel with an understanding of the basic operation of various types of DOE nuclear facility instrumentation and control systems. 

This table shows the home office hours required by a large contractor to design and procure the different types of equipment normally encountered in a chemical plant. The hours comprise all technical and clerical activities from the start of process design to project closeout. They are intended for a continuous operation, single unit plant with electronic DCS instrumentation built on a direct-hire basis on a clear site and include process-related buildings, such as a motor control center and control room. 

The inspector then places it on a pin-type conveyor which makes it possible for the air to circulate freely around each shell, thus as-.suring that the physical properties of each forging are the same. Each conveyor hook has two pairs of pins, one above the other, holding four forgings in all. By the lime the shell reaches the final inspection room, it is completely cooled. Here the shells are given a 100 per cent inspection before they are pas.sed on to the shot blast machine which cleans the inside cavity at the rate of two every 30. sec. After the cleaning operation they are oiled inside with a pre.s-.sure gun sprayer to protect the interior from rust while in transit to the machining contractor. 

There are other specialized organizations and numerous contractors and vendors doing research to develop better materials, design methods, inspection and testing methods, and other practices to enhance the safety of pipelines. Most operators have multiple staff involved in various technical committees associated with these organizations, and various key technical people carry certifications of various types. For example, key corrosion personnel typically carry various certifications from NACE. 

A 350-ton deisobutanizer distillation column, 212 feet high, was raised into position in one piece at the El Segundo refinery of Standard Oil Co. of California, Western Operations, Inc. The lift was one of the heaviest ever accomplished in the U.S. with a load of this type. Macco Refinery and Chemical Division, California, was the prime contractor for construction. [Petroleum Refiner, 37, No. 2, 184 (1958)]. Column shown was designed by one of the authors. 

If there are other employers on the site, such as contractors, the HAZCOM Program must also state (1) how these other employers will be informed of the site labeling system (2) how they should protect their own employees during normal operating conditions and emergencies and (3) how contractors and contractor-type personnel will be provided access to MSDS. 

This database focuses on work-related personal injury and illness and property damage (including that due to the operation of motor vehicles). There is a general tabular breakdown relative to individual contractors however, there is no detail as to the specific types of work or the assumed risk inherent in these particular types of work. This is an old database which was established to collect statistics for the U.S. Department of Labor. An important aspect is that the data is reported on a normalized per unit of work (200,000 person hours) basis which facilitates gross comparisons between and within industries. To emphasize the general nature of the CAIRS database, Total Injury and Illness Incidences Rates and Lost Workday Incidence Rates are depicted in Figures 4 and 5, respectively. 

Several types of part cleaners are used at shipbuilding and ship repair facilities. The types used in such facilities vary from the more simple sink and spray systems to more elaborate parts (machine) cleaners of the cold or vapor types. Most of the parts cleaners in shipyards are small — around 1.5 m x 1 m and 1 m deep - usually located in the machine shops, not the paint rooms. Most of the parts are small components being cleaned prior to being joined to other small parts into assemblies and sub-assemblies or being cleaned as part of some type of repair operation. Most of parts cleaners used were basket-type design with the parts loaded into a basket and dropped through the vapor zone several times to clean off the oils and dirt. Some shipyards use contractors to come in and change out the solvent on a routine schedule.
