Home' Work Boat World : June 2010 Contents In a social, political and economic environment that is focused
on the search for new energy sources, work boats are not only
working under more adverse and challenging conditions but
their role has expanded beyond the oil field.
Offshore wind farms, tidal and wave motion generators have
greatly expanded the need for such service providers. Work boats
are being called upon to work in deeper water and under more and
more demanding, even Arctic, conditions. On top of this, the
sinking of the Bourbon 'Dolphin' has brought to light the need for
added safety features in all deck equipment. As a result, deck
equipment must keep up with the increasing and demanding
operational and safety needs of today and the future.
Markey Machinery Company of Seattle Washington has
announced the development of a number of anchor handling tow
winches (AHTW's). They offer these units as either hydraulic or
electrically powered systems with capacities from 150 to 600
tonnes. Markey has been in business for over 103 years,
encompassing a long history of producing large, high-capacity deck
winches including towing winches.
Markey President, Blaine Dempke stated: "The new winch range
came about from a need to develop units that could handle heavier
equipment at even greater depths with inherent safety features.
Therefore we embarked on a project to match these increases in size
with winch-pulling capabilities and emergency release features."
AHTW's have traditionally only been available as hydraulically
powered, however, as a pioneer in electrically powered deck
equipment, winch automation and Markey "Render/Recover"
technology, Markey has included these advances in this new range
of AHTWs. Markey's new extra powerful anchor-handling tow
winches are currently available for custom orders.
"Requests were made from some vessel owners regarding the
possibility of using electric drive winch packages, as they believed
that these would deliver better performance and be a significantly
more effective technical solution than a hydraulic drive.
Additionally, the electric drive solution is also the most
environmentally friendly," explained Dempke. "Markey has been
producing electrically powered marine winches for over 60 years,
pioneering the use of VFD drives and automation in the marine
environment. With these requests, as well as our extensive
experience with electric drive technology, we have developed
solutions for the industry's need for inherently safe, electrically
driven 300 to 600-tonne AHTW packages.
The electric drives offer many of the same features as the
hydraulic systems, with variable speed ranges, dynamic braking,
spooling devices, with hydraulic or pneumatic operated clutches
and brake cylinders. Markey's AHTWs also include high-speed
freewheeling capability, emergency release freewheel, line
tension monitoring systems with data logging and remote access
Markey Machinery is uniquely prepared to meet the most
demanding deck machinery needs. It has a well-established
reputation for a "Hell for Stout" design philosophy and aggressive
customer service. The company has recently completed an
extensive expansion and renovation of its manufacturing facility,
adding a 929m2 assembly building and a new headquarters office
building. Markey has always taken pride in the quality of its
machinery. To document and formalise that commitment, it is
now on the verge of receiving its ISO9001:2008 certification and
has implemented Kaizen, 5S and LEAN principles to increase the
efficiency and quality of its production.
According to the company: "Anything else is just a winch".

Fukushima specialises in the manufacture of deck machinery
(windlass, mooring winches, towing winches, anchor handing
winches and more).
Fukushima was founded as a machine engineering works in
Fukushima city, Japan, in 1920.
The company's products have already been mounted on more
than 5,500 vessels of a wide variety of types including passenger
boats, research vessels, various merchant vessels, naval vessels and
offshore supply vessels, among others.
Over the company's long history, it has accrued a reputation for
supplying high-quality, high-performance equipment, its good
standing translating into repeat and return orders.
Fukushima's contribution to offshore operations occurs primarily
in its towing / anchor-handling winches and OSV deck machinery.
Fukushima's low-pressure, hydraulic deck machinery boasts
features including simple and strong construction, low noise, easy
operation, and resistance to oil contamination.
