Tug Types
Conventional Screw Tug
Worldwide, the largest number of tugs belong to this type. The towing point (e.g.
towing bits, hook or winch) is located approximately 0.45xLOA from aft. To improve
their manoeuvrability, conventional screw tugs may be fitted with a steerable nozzle,
a bow thruster or a retractable azimuthing bow thruster. Tugs fitted with the latter
device are referred to as “Combi-Tugs”.
Twin-screw conventional tugs offer increased manoeuvrability over a single-screw
tug, as the two screws can be worked independently and in opposite directions, thus
enabling the tug to pivot within its own length.
Azimuthing Stern Drive (ASD) (Z-peller)
This is a tug where normal propellers and shafts have been replaced by azimuthing
propulsion units, which enables the propeller and its associated nozzle to rotate
about its vertical axis (360 o rotation). The position of the propulsion units is identical
to that of a conventional twin-screw tug. Just as with a twin-screw tug, these
propulsion units can operate independently, making it possible for the tug to move
forwards, backwards, sideways and turn around its own axis with great precision.
The towing point on an ASD tug is located on the foredeck; however some ASD tugs
may have additional towing points on their after decks, thus enabling them to function
in a similar manner to a conventional twin-screw tug (but with increased
manoeuvrability).
ASD tugs can be referred to as “reverse-tractor tugs”. This definition is applied
mainly to tugs with stern-mounted azimuthing propellers but with limited or no towing
fixtures on their aft decks.
Voith-Schneider Tractor Tug (VST)
The term “Tractor Tug” is used where the propulsion units are located about 0.3xLOA
from the bow with the towing point located at the opposite end of the tug, close to the
stern. The main difference between the stern drive (ASD) and the tractor tug types
is the location of the propulsion units.
The Voith-Schneider Tractor Tug (employing Voith-Schneider cycloidal propellers)
was introduced mainly for ship-handling due to its exceptional manoeuvrability and
safety in operation, which is inherent in the tractor principle.
Skeg-First Escort Tug
An advance in tractor tug technology, primarily designed for active escorting of large
vessels on long approaches/passages. Similar in construction to the conventional
Voith-Schneider Tractor; however, designed specifically for exerting much larger
steering forces (generated by in-direct towing techniques).
Page 2 of 8

Azimuthing Tractor Tug (ATT)
Tractor tugs using azimuthing propulsion units were first built in the 1970’s as a
possible alternative to the Voith-Schneider system, introduced some years earlier.
The azimuthing units are placed in the same location as the Voith-Schneider
propellers, i.e., under the forward part of the hull.
Differences between the Voith-Schneider tractor tug and the azimuthing tractor tug
are:
• Propulsion systems, cycloidal propellers verses screws in nozzles
• Response time of Voith-Schneider tug is faster
• Azimuth tractor tug is more efficient (in terms of tonnes bollard pull per BHP)
Variations on the ATT design are the “ROTOR-Tug” and “Ship Docking Module”
(SDM). At this time, no ROTOR-Tugs or SDM-Tugs are operating in the Port of
Liverpool.

Propulsions Systems
At the heart of every tug, and the feature that probably attracts most attention, is the
propulsion system. In order to give an overview of the various propulsion systems,
the following table has been prepared.

Bollard Pull
The bollard pull of a tug is the amount of static force (pull) that can be exerted when
tethered to a measuring device. Mostly this is done through a secured towing line
connected to a dockside bollard. Due to the requirements of the classification
society/authority, the locations of these trials are mostly in very secluded places,
where weather conditions would have little affect on the results. These trials have
been introduced because the variety of propulsion systems available at this moment
no longer make it possible to judge the force available from a tug by the horsepower
of its engines alone. Particularly with ship-handling tugs, the trials will include the
pulling both ahead and astern, due to the fact that both functions are used during
different modes of operation.
The towing force (pull) of the tug depends on its engine power and on the type of
propeller, as becomes evident in the following table.
Type of Propeller
Conventional (with Nozzle)
Azimuthing with Nozzle (ahead pull)
Conventional (without Nozzle)
Voith-Schneider propeller
BP Ahead in tonnes/100 BHP
(approximate value)
Conclusion:
For the same installed horsepower, an ASD or ATT tug will have a higher bollard pull
rating than a VST tug.
Methods of Operation
Today there are principally two methods of ship handling operations:
• On-the-line or European method
• Push-pull method
Over the last decade, passage escort has emerged as an operational requirement for
the marine service provider at marine terminals, and is often referred to as either
PASSIVE or ACTIVE escorting, depending upon the service provided.
Passive Escorting is when a tug shadows the ship, but does not make fast. Active
Escorting is when the tug does make fast, usually as the stern tug, and is often
referred to as the INDIRECT towing mode.

On the Line
“On the line” towing means that the tug is connected to the assisted vessel by a towline.
This is the traditional method of harbour assistance in many European ports.
The towline is connected to the tug by a towing hook, towing winch or secured to towing
bits (all of which are known as the towing point). The location of the towing point will
vary between tugs types: conventional, ASD or Tractor.
The danger with towing on the line is the risk of girting and capsizing. Girting happens
when the towline comes at right-angles to the tug. The tug is pulled bodily through the
water by its tow, which can lead to deck-edge immersion, flooding and capsize; unless
the towline is released in good time. The location of the towing point on ASD tugs
(when operating over the bow) and Tractor tugs reduces the risk of girting.
When made fast to a vessel’s bow, the effectiveness of tugs towing on a line will
decrease with increasing headway. This is because, as headway increases, more of
the tug’s power is used in maintaining its position relative to the vessel, as opposed to
being applied as an assisting force through the towline.
Push-Pull
The push-pull operation means that the tug is connected to the assisted vessel by a
short line (ASD and conventional tugs will use a bow line, whilst tractor tugs will use a
stern line) and remains in close proximity to the vessel. This enables the tug to push
on the vessel, but then check/control the vessel by pulling-back on the short line. This
method originates from Japan and South-Asia.
Due to the limited power of conventional tugs when running their propellers astern, their
ability to pull-back on the line will be limited.
When the tug is not connected to the vessel by a bow or stern line, this is simply called
pushing. This method of operation is used by (amongst others) conventional tugs
operating in North America.
Indirect Towing
Indirect towing is a way of enlarging the exerted force when turning and/or decelerating
the tow. This mode applies only to the trailing tug, here referred to as the stern tug. The
tug is made fast to the vessel by a towline and is dragged by the assisted vessel. The
tug uses its thrust to maintain a sheered position relative to the tow’s heading whilst the
towing force is generated by the drag forces acting on the tug’s hull and transmitted via
the towline. The drag forces on the tug can be substantially higher than the bollard pull
when the speed through the water is greater than 6 knots (approx).
Page 6 of 8

With the towline at a large angle to the tug's centre line, indirect towing is a potentially
dangerous manoeuvre. Indirect towing requires a highly skilled tug master to achieve
the high towline forces without girting and capsizing the tug. The advent of the
purpose-built escort tug, designed for exerting such high loads, has made this
operation much more controllable and therefore much safer.
Tug Types and Methods of Operation
The table below summarises the suitability of the three distinct tug types in relation to
the basic ship-handling methods as earlier discussed. It also gives a very clear reason
why Marine Service Providers favour ASD and tractor tug types over conventional tugs
for ship handling.
Given the fact that, where possible, Push-Pull is the preferred method of operation, it
could be said that to undertake the equivalent operation employing conventional tugs
only, double the number of conventional tugs could be required when compared to a
similar operation employing either ASD or tractor type tugs.
Table of Tug Types and Methods of Operation
TUG TYPE METHOD REMARKS
Conventional Tug On the line Poor manoeuvrability at large
sheering angles
Push-Pull Only pushing or pulling
Indirect Very difficult due to lack of
directional control of the tug
Azimuth Stern Drive
Tug
(ASD) (Z-Peller)
Tractor Tug
(VST or ATT)
On the line Good performance when working
over the stern, but risk of girting
exists at higher speeds. Working
over the bow reduces girting risk.
Push-pull Very good performance working
over the bow
Indirect Good performance working over the
bow
On the line Good performance with reduced risk
of girting.
Push-Pull Good performance
Indirect Good performance with reduced risk
of capsizing

Conclusions Regarding Tug Types
Assuming normal port operations with maximum ship speeds of six to seven
knots, it can be concluded – with some reservations – that the suitability of different
tug types can broadly be ranked as follows:
As forward tug towing on a line:
• ASD-tugs (operating from stern winch)
• Combi-tugs
• Conventional tugs
• Tractor Tugs and ASD tugs (operating from bow winch)
As stern tug towing on a line:
• Tractor Tugs and ASD tugs (operating from bow winch)
• Combi tugs
• Conventional tugs
When operating at a ship’s side:
• ASD tugs and Tractor tugs
• Combi-tugs
• Conventional tugs
At speeds of over 7 knots as stern tug:
• Escort tugs
Ship handling tugs operating in the Port of Liverpool are categorised as
follows:
