Harken Industrial Oceanic Cable blocks are used on research vessels to safely lead data cables and towed objects overboard. Previously, offshore research vessels had been using large, heavy blocks to lay fiber-optic research cables. These cumbersome blocks require multiple technicians to move them into position, which can result in damage to the cables.
Using lightweight, extremely strong materials, Harken Industrial has designed an alternative block. Not only is it light enough to be handled by a single operator, but the reduced block weight allows it to align to the cable payout. The sheave diameter accommodates the cable’s large-bend radius, while the throat is wide enough for the wire terminals to pass through.
The Oceanic Cable block is used by Woods Hole Oceanographic Institute, University of Rhode Island (USA), and University of Alaska – Fairbanks oceanographic research departments, as well as many other research organizations.
