Ohmsett Inspection, Survey & Testing

Oil Spill Response Equipment Testing & Research

Independent full-scale testing of booms, skimmers, sorbents, dispersants and other oil spill response equipment with real oil under controlled wave and tow conditions.

Description

Ohmsett's 203 m outdoor saltwater tank accommodates full-size oil spill response equipment, tested with specified real oils, including dielectric oils, rather than surrogates. Evaluations follow ASTM F20 standards.

Key features

Equipment tested includes booms, fire-resistant boom, skimmers, sorbents, temporary storage devices, pumping systems, remote sensing devices, dispersants and unmanned underwater and surface vehicles
Capabilities extend to in-situ burn equipment, emulsion formation and broken-ice testing
Measured parameters include oil recovered, viscosity, oil-water ratio, droplet size, tow speed and sea state
Instruments include LISST particle analyzers, fluorometers and ROVs

Applications

Performance testing and research on oil behaviour, pumping, towing forces, oil/mineral aggregates, biofuels, submerged oil and dispersants.

Specifications

Tank dimensions	203 m × 20 m × 2.4 m deep
Water volume	10 million liters saltwater
Tow speed	up to 6 kn
