HECSALV (or its Navy equivalent, POSSE) was used in all the incidents displayed.

Oil Outflow Assessing the amount of oil lost is critical to mobilization decisions.HECSALV™ provides the capability to evaluate oil loss including the effects of density differences and tides.

	Grounding Many different kinds of grounding have been evaluated using HECSALV™. These include both rigid and penetrable shelves, and single and multiple pinnacles. Structural evaluation of the impact of ground reactions is built-in.

Intact Stability There are many facets to Salvage Engineering. Intact stability calculations available in HECSALV™ include unusual loads and direct evaluation of free surface effects at large heel angles.

	Free-Floating Damage Evaluation of free-floating conditions including equilibrium and partial flooding is available in HECSALV™.

Tide Cycle Evaluation Tides play and important role in oil outflow, residual strength, force to free and many other factors. HECSALV™'s tide cycle analysis lets one establish a time sequence of analyses that span one or more tide cycles.

	Lightering Intact & Damaged Tanks A key part of the salvage operation is often a lightering plan. HECSALV™ permits definition of lightering operations that include transfers within the vessel, to lightering barges, or if necessary, into the sea.
Transfers from intact or damaged tanks can be modeled. A time sequence analysis, including tital effects and lightering, provides the salvage engineer the ability to project the consequences of salvage activities.

	Structural Damage Will she break in two? Is she safe to tow? These are common questions in salvage. HECSALV™'s structural damage assessment capabilities help answer these questions.

	Rapid and Towing Analysis HECSALV™'s Rapid Analysis feature allows the the salvage engineer to make quick, rational estimates of salvage issues. More data can be incorporated as it becomes available, so that the best information available is always used.
