Problems solved by technology

However, with the existing tow point design, the mean time to failure of the tow cable connection is significantly reduced due to the wear problem of the tow cable mentioned earlier
Depending on the type of towing line, these wear issues significantly increase the cost of repair, maintenance and replacement of the towing line or towing point of the tugboat

Embodiment Construction

[0032] In this specification, exemplary embodiments of the tugboat and tow point of the present disclosure are shown by way of example only. These should in no way be considered as limiting the scope of the present disclosure. The drawings are only schematic. In the drawings, the same or similar reference numerals will be used for the same or similar components or features.

[0033] In this specification, vertical and horizontal refer to planes or directions in their usual meanings, whereas directions in relation to a vessel or tugboat defined by horizontal or vertical are those when the vessel or vessel is in a floating position, in a normal stable position is used unless otherwise specifically defined.

[0034] In this specification, substantially frictionless has to be understood to include, but not limited to, substantially lower than the friction in the towing lines and towing points in known towing operations for the same vessel and tugboat. Substantially frictionless...

Abstract

A tugboat having at least one towing winch and a movable tow point arrangement, wherein the tow point arrangement can guide a towing cable from the tow winch to a vessel to be assisted, the tow point arrangement comprising a rotating element of at least partially guiding the tow line such that in use tractive forces on the line are at least partially transmitted to the tugboat through the rotating element which is free to pivot about a first axis and which The shaft is fixed to the arm, and the arm is pivotable about a second shaft, the second shaft is spaced apart from the first shaft, and the second shaft and the first shaft are non-parallel.

Description

technical field [0001] The present disclosure relates to a tugboat for use in a harbor and / or at sea, comprising at least one towing winch. Tugboats are used to assist ships at slower speeds while towing in port. A first end of the towing cable is connected to the towing winch. The towline is guided through the tow point and connected to the vessel being assisted, creating an efficient towline connection on the assisted vessel capable of withstanding significant tractive forces, thereby improving the maneuverability of said vessel. Tugs at sea are generally restricted to operating in this manner due to unfavorable operating conditions at sea compared to port use. Background technique [0002] The field is divided into two main towing modes, known as pull mode and push mode. In the tow mode, the tug creates traction on the tow line connection, resulting in a force on the vessel being assisted. In jacking mode, the tug exerts thrust on the vessel being assisted through jac...
