Markey Machinery is America’s oldest privately-held winch manufacturer and a leader in the design and manufacture of deck machinery for commercial and scientific applications. Products include deep-sea oceanographic research winches, single, double drum and traction winch systems, commercial towing and ship-assist/escort winches, winch instrumentation systems, sheaves, capstans, and windlasses. The business was founded in 1907 by Charles Markey. Markey takes the support and repair side of business very seriously, servicing its own equipment and machinery for as long as it lasts, the stern-wheeler tug Portland a working example, as the company to this day services and makes parts for the tug’s steam steering system the company built in 1947.

In 2010 Markey reopened its expanded, modernized and renovated factory in Seattle. For the first time, since 1943, it’s entire staff of engineers, tradesmen, and administrators are co-located. The grounds include 20,000 sq. ft. in new building construction, 10,000 sq. ft. of upgraded or renovated manufacturing space in the existing buildings, and numerous key infrastructure improvements. Markey innovations include “on-the-fly” level wind controls, double- drum traction winch systems, automatic variable-speed transmissions, and below-deck drive systems. Its most signif- icant winch innovation is Markey's Asymmetric Render-Recover (ARR) hawser winch technology. This concept pro- vides safe line control by operating within an upper and lower tension range selected by the tug Captain. Markey's

Render-Recover winches maintain constant line tension and automatically compensate for tug maneuvers as well as surge, heave, and pitch motions that would be nearly impossible for a man to achieve using standard lever controls.

Automatic, real-time tension control keeps slack out of the working line at all times and prevents snap-loads from occurring, thus reducing the risk of line breakage or damage to the line's tie-off points. In addition to designing and manufacturing prototype machinery for a variety of customers, Markey is engaged in transferring its Asymmetric

Render-Recover controls technology to other marine applications. A 760 HP Class III Hawser Winch using these controls proved capable of escorting and assisting LNG tankers in the dynamic open ocean environment. Newer applications for this technology include: offshore oil and gas dive support vessels requiring efficient execution of pre- cision four-point moorings and research vessels requiring the decoupling of instruments, samplers, and other pack- ages from wave-induced ship’s motion for improved operating safety in high sea states.

TriOS has moved via limnology applications towards drinking water, waste water and process control. As ‘light and water’ is not anymore the correct slogan for most of the media where TriOS sensors are used, the motto was modified to ‘light and liq- uids.’ Despite the movements of the core business, TriOS will never loose it’s passion for optics and marine applications. Using light as a direct measuring principle is an environ- mentally friendly principle. TriOS develops and manufactures optical sensors for scientific and industrial applications. TriOS was the first com- pany offering hyperspectral sensors for environmental applications. The most popular ones are still the RAM-

SES radiometers.
