Embodiment Construction

[0016] The emergency towing and rear towing combination mechanism for oil tankers includes a fairlead member 1, an emergency towing strong point member 2, and a steel shaft 3. The implementation steps are as follows:

[0017] 1. Make a deck-type fairlead member 1 with a permissible load of 200 metric tons, and five reinforcing ribs 4 are arranged on the fairlead wall, of which two are arranged in the horizontal direction and are symmetrical to each other;

[0018] 2. Make a horizontal emergency towing strong point component 2. The emergency towing strong point component 2 consists of a top cover plate 5, two outer reinforcing brackets 6, two inner reinforcing brackets 7, a top lapping plate 8, a bottom plate 9 and emergency Drag strip 10 composition. The emergency towing belt 10 is fixedly connected to the bottom plate 9, the size of the top cover plate 5 matches the size of the fairlead member 1, the top cover plate 5 is fixedly connected to the emergency towing belt 10 thro...

Abstract

The combined emergency oil tanker towing and back towing mechanism includes a mooring hole member and an emergency reinforced towing member. The combined emergency oil tanker towing and back towing mechanism is made through the following steps: making deck type mooring hole member; making emergency reinforced towing member including outer and inner reinforcing toggle plate and emergency towing belt fixed onto a bottom plate as well as top cover plate and top lapping plate; making steel shaft; and assembling to form the combined mechanism. Of the combined emergency oil tanker towing and back towing mechanism, the emergency reinforced towing member is used in emergency tail towing, and the deck type mooring hole member and the steel shaft are used for back towing. The application in a 159000 ton oil tanker proves the feasibility, and the present invention has the advantages of small occupied space, fast operation, high safety, etc.

Description

(1) Technical field [0001] The invention relates to an emergency towing and after-tow device for an oil tanker, in particular to an emergency towing and after-tow combination mechanism for an oil tanker. (2) Background technology [0002] All types of oil tankers above 20,000 tons must comply with the relevant clauses suggested by "OCIMF" (International Petroleum Association) (it will be enforced after the applicable period). The towing device, the fairlead and strong points towed behind require a permissible load of 100 metric tons for ships of 20,000 tons to 50,000 tons, and 200 metric tons for ships of 50,000 tons or more. In the past, it was designed as a separate type, that is, a set of tail emergency towing device and a set of rear towing device were respectively installed on the upper deck of the tail. strengthening structure. For some oil tankers, the space on the main deck at the stern is narrow, and if a separate type is used, it may be difficult to design the mo...
