![]() ![]() They have been developed after a number of serious (tanker) accidents in recent years. Coastal states often use seagoing tugs to avert an imminent environmental disaster.Įscort tugs are used to escort (large) ships along dangerous passages. Ever since the introduction of semi-submersible heavy lift carriers, long distance towing is used less often as a method of transport. Partly completed ships, floating wrecks, docks, drilling rigs and other large floating objects that have to relocated can be towed by tug boats. Salvage, Towing, Anchor Handling in the offshore industry, Environmental Service, Ships with engine trouble. The towing winch is of great importance because it has to be able to transfer the total force of the propeller to the towing line. The point of application of the force in the towing line must be located close to the midships in such a way that the force has no influence on the manoeuvrability. This guarantees that the towing line has some freedom of movement. Often multipurpose ships are employed as container feeder.Ī common characteristics of all tugboats is their low aft deck. The feeder may be equipped with cargo gear. Large container vessels usually do not have their own loading gear.Ĭontainer feeders are small or medium sized ships starting at 200 TEU that specialize in transporting cargo from small ports to large ports, or for use in services which are not profitable for the larger container vessels. The big container ships can only go to the largest ports because of the ship’s size and the transfer capacity of the port. Big intercontinental container vessels up to 8,400 TEU (1999)ī. There are two main types of container vessels:Ī. The transport by water is just a link in the chain of transport.Ĭontainer vessels have grown from a capacity of 1500 TEU (1966) to approximately 8000 TEU (2002).Īmount of TEUs and FEUs below the weather deck along with their heights. ![]() The specific advantage of the use of containers is that the cargo can be transported directly from customer to customer, and not just from port to port. Since the 1960s, the transport of containers has continued to grow. 2.Inner ring diameter of dredge cutter head is from 830mm to 2400mm.ģ.The cutter head have replaceable dredge teeth.Ĥ.The dredge cutter head have many applications, can be used for rock, mud, slurry, sand and gravel.ĥ.The superiority of the rock cutter head is the result of unmatched design and metallurgical capabilities.ħ.Easy to maintenance, with minimum maintenance cost.Ĩ.Exceptional wear resistance, high quality.ĩ.The cutter head can be supplied with shaft, bearing and gearbox.ġ.We can supply the cutter heads and tooth system for cutter power of 35kW up to 6000kW.Ģ.Providing various of dredge cutter heads, customization in available. ![]()
