Towing gear

The towing gear comprises of various components which can be used all or only in parts, depending on the requirements of the individual tow.
Following components can be part of a towing gear :


Bridle
built of chains or towing wire it serves as a triangular connection to both sides of the tow. Both sides join in the "flounder plate", which is
usually a heavy triangular steel plate to which the main towing wire is connected.


Towing Wire
A galvanized steel wire stored on a towing winch to connect to a tow. Usually the towing wire is stored on towing winches.
The seagoing tugs of Fairplay are equipped with 1.400 m of 52 mm towing wire - a weight of 14,5 mtons .


Stretcher

Are used especially for short sea towages and for port operations. Stretchers absorb the heavy stresses on short towing wires, caused for example
by swell. Stretchers are mostly made of polyamid lines.


Shackles
Are used to connect the parts of a towing arrangement .


Towing winch
Today the towing wire is usually stored on a towing winch. The advantages of a towing winch are obvious. The towing wire can be lowered and
hoisted anytime and a spooling device is storing the wire layer by layer turn by turn avoiding damage to the wire. Modern winches offer double
or triple drum towing wire storage. FAIRPLAY’s tugs of the Fairplay-21 type class have double drum towing winches aft and single drum on the bow.
The latest units of Fairplays fleet - FAIRPLAY-25 and FAIRPLAY-26 have double drum towing winches fore and aft. Towing winches with two or more
drums mounted vertically to each other are called waterfall drum towing winches.


Preventer
The movements of the towing wire on a tug are similar to those of the saw blade. In order to protect the bulwark of the tug a preventer is mounted
over the towing wire and is fixed in the bulwark area by steel wire. The preventer is made of special plastic able to stand the heave forces of the towing wire.


Emergency Towing Wire (ETW)
Is installed on the towed object as a spare towing connection in case that the main towing wire will be damaged. To enable the tug to pick up the emergency
towing line, a floating ball and a long messenger line is connected to the ETW. is installed on the towed object as a spare towing connection in case that the
