BoomVane - improved efficiency & economy for advancing vessel systems

Towed boom systems can now be deployed by a single vessel only. The power and stability of the BoomVanes allows for unparallelled performance with a range of towed boom and skimming systems, in all navigable waters. Light and compact, the BoomVanes can be launched also from smaller work boats - all that is required is a displacement vessel with a  sturdy cleat and sufficient torque.

Main applications:

• Large vessel side sweep - one BoomVane replaces ourigger arm/jib

• All vessel trailing sweep - one BoomVane replaces 2:nd vessel

• All vessel extra wide trailing sweep - two BoomVanes replaces 2:nd vessel

The sweep width is function of boom draught and tow line length - with shallow draught coastal booms a single vessel can operate a trailing sweep with up to 150 m swath.

Every mariner operating a two-vessel towed boom system with a fixed apex component - skimmer, boom opening etc - has experienced the challenge in maintaining the system formation (eg speed and distance coordination). With a single tow vessel and BoomVane(s), this is no longer an issue - once set, a BoomVane sweep stays set throughout speed changes and resumes correct formation following turns without the need for adjustment. Further to the savings and ease of handling gained with only one vessel, the elasticity inherent in the BoomVane system aslo saves wear and tear on the boom. 

Some examples of single vessel operations (click on the image to enlarge / run video)

		Trailing U-sweep Basic slow speed sweep configuration for both large and small vessels. With one BoomVane only, the sweep is offset from the vessels path which allows for 'close shave' of shorelines and shallows.
		Trailing V-sweep (high speed) With an open apex and induced drag (eg sea anchor or flow thru skimmer) on the apex, the U-curvature of the boom is straightened out to a V which allows higher sweep speed without entrainment. The example is from a Swedish Coast Guard exercise with the RIB towing a 'fore sweep' in > 2 knots, ahead of the recovery vessel to concentrate the spill.
		Open apex, trailing U/V sweep: With long tow lines a single work- or patrol boat can operate very wide sweeps (100-150 m depending on the boom). In this case, a Swedish Coast Guard patrol vessel tows an open apex sweep with two BoomVanes ahead of a dedicated spill recovery vessel to triplle its swath.
		ADS - advanced deployment system for trailing sweep: ORC has designed a semi-automatic deployment system for the Swedish Coast Guard's sea sleds, each carrying  two BoomVanes and 180 m self-inflatable boom. The entire sweep is all out and running in 20 minutes.      Click to view a slide show of the deployment sequence.
		Harbour Buster  oil containment system: Offset trailing or side sweep with Harbour Buster (NOFI) advanced containment system with one BoomVane.
		Neat Sweep dispersat application system: Offset trailing sweep (one BoomVane) or extra wide trailing sweep (two BoomVanes) with the Neat Sweep dispresant system (Elastec).
