Oil Spill Cleanup Device Tailored for the Arctic

Friday, January 4, 2019

A new oil spill response device capable of cleaning up spills in arctic conditions has been launched in an effort to bolster Norway’s spill preparedness.

The new device, dubbed Arctic FoxTail, is a winterized version of H. Henriksen’s standard Foxtail vertical adhesion band (VAB) skimmer, which filters out oil spills from the seawater using its sorbent mops. The system is capable of salvaging large quantities of oil after a spill, without much unnecessary water.

Tonsberg-based H. Henriksen began to develop the arctic ready system through the Norwegian Clean Seas Association for Operating Companies (NOFO) and Norwegian Coastal Administration (NCA) Oil Spill Response 2015 program, which invited vendors to develop new commercially avilable technologies to handle oil spill recovery in arctic conditions. H. Henriksen’s Arctic FoxTail proposal was accepted, and protype development started in 2016.

The scope of the project was to widen the weather widow in which oil can be taken from the water with skimmers. According to H. Henriksen, the old skimmers are very redundant to the sea state and weather, but their efficiency is reduced in cold weather when ice starts growing on the machines (mainly from sea-spray).

The newly launched winterized version features an integrated transfer pump, insulated cover and hydraulic heating system, representing a major redesign of the standard model.

“Implementing heat and insulation to the machine and moving the transfer pump to the skimmer allows for stable and continuous operations at considerably lower temperatures compared to the standard Foxtail,” explained Trygve Egenes, Managing Director of H. Henriksen. “Also, the weather window for the use of the vertical adhesive band skimmers has significantly increased.

“This modification, together with the advantage of the VAB skimmers, makes the Artic FoxTail a useful oil spill response device in arctic conditions.” 

The standard FoxTail operates in -6°C, compared to the new Arctic Foxtail which can operate -21°C under the same sea temperature and wind conditions, the developer said.

H. Henriksen said the Arctic FoxTail proved capable of stable and continuous operation in sub-zero arctic conditions during recent testing on board MS Polarsyssel in Longyearbyen, Svalbard.

The company is now delivering the first Arctic FoxTail to the NCA.
