Facility Response to Accidental Loads

Facilities are normally designed elastically for operational loads. For accidental loading Petrellus Engineering takes structures and equipment beyond the first yield and focuses on the utilisation of inherent strength reserves and redundancy. Specialist techniques, many of which have been developed in participation by Petrellus Engineering, covers aspects such as:

	Plastic analysis
	Re-distribution of load within redundant structures or pressurised equipment
	Time lapse analysis of progressive failure
	Residual strength of material in extreme conditions, e.g. high temperatures

These techniques proved to be very beneficial to mobilise existing strength against accidental loads such as the following:

	Fire
	Explosion
	Ship impact, collision and grounding
	Dropped objects
	Extreme environmental loads
	Impact of projectiles
	Earthquake
	Subsidence

We have more than 20 years experience of assessment of plant and structural response to accidental loads.
