FEATURE ARTICLE
NES motors are robust machines designed for continuous duty
in tough marine environments. The company offers a wide range
of asynchronous motors as well as permanent magnet machines
for high torque/low speed or special demand for high efficiency
and when low weight is required.
The double jacket motors represent the latest generation of its
asynchronous motors, designed for marine heavy-duty applications where limited space and natural ventilation are key factors.
The double jacket cooling system has proven to be a superior
design for variable speed main propeller and thruster applications with its high output to size ratio and a high degree of protection towards salient and humid environments, says the company.
They are particularly silent emitting up to five times less noise
than conventional air-cooled motors.

Designed for high reliability even in the worst operating environment, NES generators feature long life endurance of electrical
components and housing. They are impregnated with high-grade
resin by vacuum pressure impregnation (VPI). VPI uses vacuum
and pressure to seal porous materials with varnish or resin, a
process used primarily for high-voltage motors and generators
to fill gaps in materials to create a void free insulation. They are
also equipped with PT 100 sensors for temperature monitoring of
stator winding and bearings, and an additional protection against
hostile environmental conditions (tropicalization) is provided as
standard.

Havyard Group provides zero emission shipbuilding technology
They are also home to its parent company, Havyard Group
ASA, a ship technology company specialized in the design and
construction of zero emission vessels. Havyard Ship Technology
operates its own shipyard in Leirvik, at the mouth of Norway's
and northern Europe's longest fjord, the Sogne Fjord, and provides zero emission design and technology to other shipbuilders
worldwide. NES was established in 2009 as a supplier of advanced diesel electric, hybrid electric, and 100% electric propulsion systems for the global marine market. Last year, it merged
with NCS, a sister company in the Havyard Group, adding to its
product range the automation and navigation/bridge systems.

NES transformers, in foreground right, including 3-phase dry type
NES also builds a complete range of low and medium voltage
transformers for marine applications. The transformers are
designed to offer not only the best possible reliability for marine systems with special attention on inrush current in order to
prevent short circuiting. Its portfolio includes marine distribution
transformers, step-down transformers, auto transformers and
multi-winding transformers. All windings are vacuum pressure
impregnated (VPI) with high grade resin in order to withstand the
magnitude of mechanical and electrical shocks and vibrations
that can be expected in marine environments.
Based in the seaport of Bergen, NES is located in the heart of the
maritime clusters on the west coast of Norway fronting the North
Sea. The maritime clusters are home to a unique concentration
of maritime companies, specialist research and educational institutions focused on green innovation for oceans of the future.
