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.

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.
