Human Factors Assessment of USCG 47-Ft Motor Lifeboat
Abstract
Part I documents the ergonomic and safety deficiencies noted during an on-site familiarization and inspection of the prototype 47-ft motor lifeboat. The following human factors operability and habitability problem areas are addressed: steps, platforms, and railings; doors hatches, and passageways; controls; instruments and displays; workspace; and habitability considerations. Approaches to problems are indicated in the form of suggestions for possible redesign, reconfiguration, relocation, or replacement of equipment. Deficiencies fall into these categories: design of ladders; design and configuration of hatches; location and arrangement of controls, instruments, and displays; design of seating; and workspace layout. Part II initiated general and specific recommendations for re-configuration of the open enclosed steering stations. A structured operational test and evaluation protocol was followed to fully address all human factors problem area. Mock-ups of the open and enclosed steering stations were constructed for the purpose of evaluating alternative configurations of equipment layout (see Appendix). Criteria were followed to judge the appropriateness and value of all recommendations. First, wherever possible, generally accepted principles of Human Factors Engineering were employed. A second test criterion was the elimination of dysfunctional arrangements, such as one piece of equipment interfering with another.
