ERRV as an Emergency Protection Components in the Offshore Sector Activities

Abstract

The article in the short form presents a problem of protection of human activity in the offshore sector. Authors particularly focused on the analysis and presentation of highly specialized vessels — ERRV (Emergency Response and Rescue Vessels) which are specially designed to ensure safety in the offshore sector; their equipment and its appropriate use. Specific solutions and measures, their capabilities and limitations were presented.

Comparative Study of Machining Technology Selection to Manufacture Large-Size Components of Offshore Constructions

Abstract

The focus of this paper is on process planning for large parts manufacture in systems of definite process capabilities, involving the use of multi-axis machining centres. The analysis of machining heavy mechanical components used in off-shore constructions has been carried out. Setup concepts applied and operation sequences determined in related process plans underwent studies. The paper presents in particular a reasoning approach to setup sequencing and machine assignment in manufacturing large-size components of offshore constructions. The relevant reasoning mechanism within a decision making scheme on generated process plan is shown based on a case study derived from the offshore sector. Recommendations for manufacture of selected exemplary and typical parts were formulated.
