Abstract

The article considers the issue of the functional sustainability of the system for lifeboat launch from an offshore oil and gas platform. Technological risks of the sea launch are largely determined by the high level of positioning of the launch ramp above the water line. During an emergency launch of a loaded lifeboat it can be affected by wind gusts and collide with supporting structures of the platform. An analysis of accident data on offshore oil and gas rigs and platforms has shown the disastrous consequences of such a scenario. In addition to the destruction of the hull of a lifeboat, the possibility of the lifeboat release mechanism damage may also lead to lifeboat hanging or falling down. In order to eliminate the possibility of such outcomes, the article proposes the application of the design features of the offshore oil and gas structure launch ramp and to place the lifeboat onto a special damped descent platform.

Keywords: lifeboat davit, functional sustainability of the davit, evacuation of staff, gravitational marine installation, semi-submersible drilling rig, jack-up drilling rig.
