Seismic towed arrays undergo signicant loading
during operation. The towing forces from the
vessel combine with drag from the sea and lateral
loads from diverter and cross chains. These
complex loads need to be correctly controlled to
ensure that the seismic array operates correctly.
Using our expertise in understanding the difculties
associated with working in demanding conditions,
our towing attachments and ancillaries help protect
the seismic survey cables from over bending and
to increase the local stiffness of cables at the
attachment point.
Vor HR (Helical Rod)
The Vor HR (Helical Rod) System is a robust set
of helically twisted wires, supplied with end caps
so that no sharp edges are present on the outer
surface of the cable.
• Localized abrasion resistance to cable
• Increased grip capacity by spreading the
load over a greater area of cable
• Superior grip capacity at connection point
when used in conjunction with Vor UTPP
(Umbilical Tow Point Protector)

Vor MBW (Multiple Ballast Weight
Assembly)
The Vor MBW (Multiple Ballast Weight Assembly)
provides a secure and easy to handle ballast
for attachment to Lead-in cables. Typical ballast
weights are 75kg, 100 kg and 150 kg, although
ballast weights can be tailored to your needs.
• Secure attachment to lead-in cable
• Integral bend stiffeners ensure load is spread
over the length of the unit
• Lead-free ballast solution Information needed to
specify Vor MBW
• Cable diameter and tolerances
• Cable outer jacket material

Vor UTPP (Umbilical Tow Point Protector)
The Vor UTPP (Umbilical Tow Point Protector) is
specically designed to aid attachment of a tow
point to the gun umbilical.
• Helical rods to ensure integrity of the gun
umbilical
• Helical rods and olive arrangement ensure
that the tow point has signicant grip capacity
Vor CM (Connector Mounted Assemblies)
The Vor CM (Connector Mounted Assemblies) is
designed for mounting onto the Lead-in or Streamer
Connector and meets the different protection
requirements.
• Principle application as per lead-in assembly
• Internal clamp prole to suite termination
• Full cable strength attachment point

Vor LB (Lead-in Bend Assembly)
The Vor LB (Lead-in Bend Assembly) is used as
an attachment point on seismic survey cables for
towing applications. The assembly protects the
cable from over bending by increasing the local
stiffness of the cable at the attachment point. A Vor
LB allows for assembly over a pre-terminated cable
and is generally used on seismic survey lead-in
cables to attachment towing chains, paravane type
diverters or otation.
• Oversized bore bend stiffener with color coded
packers to suite numerous cable sizes
• Allows for assembly over pre-terminated cable
• High grip capacity on the lead-in cable
• Ideal attachments for diverter and tether head
