Production Facilities.
The haiards analysis should use systematic approaches to identify failure scenarios. Several widely known approaches are preserned in Section 7.
3 Basic Facilities Design Concepts
3.1 GENERAL
There are many different types of facilities in offshore producing operations. These vary from single well structures to multi-well, self-contained, drilling and production facilities- and their utilities and living quarters vary accordingly. To plan and design production facilities for offshore structures that will provide personnel safety and protection of the environment. many factors must be considered. Some of the more important factors are presented in this section.
In planning and designing thcilities. consideration should be given to number and type of wells. oil and gas processing requirements, anticipated production rates, number of people to be housed on the structure, mitigation and evacuation philosophy, type of control system, and electric power source. Consideration should he given to other operations on the structure, such as drilling and well workovers. The distance between the platform and shore-side terminals or existing transportation infrastructure is a consideration when planning pipelines, storage of spare parts and expendables and required on-site maintenance capabilities. Facilities installed in remote locations require considerably more preplanning than those located near existing transportation facilities and supply points.
Utilities on offshore structures may include potable water, non-potable water, diesel and helicopter fuel, electricity. fuel and power gas. treating chemicals. instrumetfl and utility air, sewage treatment and garbage disposal. A single well structure may not require the installation of any utility system: a self-contained manned structure may require multiple utilities.
Concepts which may be justified for new designs are not always the appropriate choice when considering the modification of existing facilities. Marginal increases in safety are ofien more than offset by incremental safety risks associated with performing the construction required for a modification. Thus, while a specific design feature may he preferable to an operator in a new design. it may be perfectly appropriate for an operator to decide that retrofitting an existing facility to incorporate the feature is not warranted.
The concepts discussed in this section are meant to apply to new facilities, These concepts should also be considered when reviewing existing facilities. However, before any recommendations for modifying the existing facilities are adopted. the operator should balance the risks associated with the modification against the expected risk reduction due to the modification. This analysis should take into consideration the operator’s safety experience with the existing design.
3.2 APPLICABLE CODES, REGULATIONS, STANDARDS, AND RECOMMENDED
PRACTICES
Facilities and cquipmcnt should be designed, fabricated and installed in accordance with the latest applicable industiy standards and recommended practices, and in compliance with current regulations of thc authorities having jurisdiction. Process systems and design aids are listed in Table I. Some design codes, standards and recommended practices for process system components arc listed in Table 2. These design aids should be considered where appropriate and supplemented by prudent engineering judgnwnt.
Requirements for means of escape, personnel landings, guard rails, and lifesaving appliances normally are specified by the authority having jurisdiction. For example, United States, U.S. Coast Guard Rules and Regulations contained in 33 CFR subchapter N Outer Continental Shelf Activities, Parts 140 through 147 set requirements in olThhorc waters of the U.S. Likewise, in OCS waters of the United States, requirements are specified by Minerals Management Service. 30 CFR Parts 250 and 256, Oil and Gas and Sulphur Opera. tions on the Outer Continental Shell.
