Ship Bio Security

Ship bio security for areas which are protected or offer refuge and facilitate the settlement and survival of bio-fouling organisms. Examples of these areas are rudder hinges, bow thrusters, bilge keels, sea chests and rope guards.

Although the bio-fouling levels on any individual vessel may seem insignificant, the capacity of some species with pest potential to successfully breed in large numbers can constitute a threat. The ship bio security risk of incursions is multiplied by the frequency of vessel visits. Prevention of new incursions by management of vectors to minimise the risk of introduction and translocation enables protection of the marine environment.

Hull Surface Treatment (HST) technology provides an effective anti-fouling treatment to the laminar flow areas of commercial shipping by applying thermal shock to these niche areas. This more specialised and detailed treatment does require diver intervention as opposed to the Standard HST application to hulls due to using a much smaller hand-held HST thermal applicator.

The HST Niche applicator (HSTNA) is a lightweight, portable and adaptable device able to effectively negotiate the various shapes and angles associated with oil rigs, off-shore structures, sea-chests, bow thrusters, rope guards, sea inlet pipes and overboard discharge. This process is capable of delivering a fatal ‘thermal shock’ to all levels of bio-fouling and is identical in terms of the patented technology established for Hull Surface Treatment (HST) technology.
