We are Huisman. We design and manufacture
heavy construction equipment for the world’s
leading companies in the renewable energy, oil
and gas, civil, naval and entertainment markets.
Our products range from Cranes, Pipelay
Equipment, Drilling Equipment and Winches,
to Vessel Designs and Specials.
The history of Huisman is one of setting new
industry standards. Of making impact, since
1929. With step changing technical solutions
that vary from stand-alone to highly engineered
integrated systems. From concept to installation
and lifetime support. In these times of transition,
our passionate workforce and worldwide
production, service & sales facilities make us
equipped for impact.

Huisman has developed a range of heavy duty Anchor
Handling and Towing Systems, providing a greater level of
safety, simple shipyard installation, higher functionality and
DNV compliance.
Winches are the heart of products such as cranes, drilling
equipment and pipelay systems, which Huisman is building
for decades. This ranges from subsea installation winches to
deepwater mooring winches and anchor handling and towing
winches.
Based on our extensive experience in the design and delivery
of equipment, Huisman has developed a new and revolutionary
design for a range of electric driven anchor handling and towing
winch systems, offering a greater level of safety, redundancy
and functionality. Handling tools, including anchor launch and
recovery systems and cable lifter exchange systems, have been
developed to further improve safety and efficiency in anchor
handling operations.

SAFETY FEATURES
The “New Generation” Anchor Handling and Towing System
The Huisman electric driven Anchor Handling and Towing
Winches have extended functionality. The new configuration
uses proven industry concepts such as water cooled clutches
and frequency controlled electric motors.
To meet the increasing demands of deep water operations,
several features are incorporated to safeguard vessel and crew.
Emergency release function
To assure vessel safety during harsh offshore conditions with
the risk of dangerous forces jeopardising the vessel stability, an
emergency release function is integrated in the winch drive train.
A water cooled clutch allows instant free running of the winch
drums, with the possibility to regain control over the wire or chain
when stability is regained. This feature complies with the latest
recommendations of the International Maritime Organization
(IMO) with regard to response time and residual line tension.
Maximise permissible line tension by Torque limiter
The winch system can be set to a maximum permissible line
tension. This setpoint is determined prior to the start of the
offshore operation. The set value could depend on for example
the line’s loading characteristics. The water cooled clutch will
slip when the preset torque value is exceeded and as a result
the winch will payout wire.
Improved snatch load protection
The water cooled clutch protects the winch system against
snatch loads that may occur during anchor handling, towing or
ploughing operations. Peak loads are better absorbed by almost
a direct link between the drum and water cooled clutch that is
subsequently linked to the drive system. Therefore, shock loads
are basically directly absorbed by the clutch. Also, the clutch
does not have a stroke limitation in case of a snatch load.
OPERATIONAL FEATURES
High speed payout
Saving valuable vessel time is achieved in high speed payout,
where the the water cooled clutch is set to slip in a controlled way.
Accurate winch control
Using high precision electric drives in combination with direct
load measurement in the torque flange, operators are offered
full winch control in all operating modes.
Fuel efficient, environmentally friendly
Considerable saves fuel and subsequently emissions. Electric
drive systems present up to 30% higher efficiency.
Easier Installation
Design of the equipment is carried out with low shipyard
installation costs and risk in mind. The pinned-type foundation
allows for a quick and easy installation sequence without the
need for lineup and under grouting of winch supports. The
electric drives eliminate requirements for heavy low pressure
hydraulic piping, resulting in months of extra installation time.
Winch range
Our current range of Anchor Handling and Towing Winches are
DNV and ABS compliant and cover a wide range of line pull.
Designs can be tailored to client requirements.
