Ship Handling

An excellent training video which will be greatly appreciated by the ship navigators. The audience for this training would consist of the future mariners, however it will also interest professional seamen since they may find something new. Every seafarer knows of the strong winds and heavy seas that are commonly caused by the fully developed tropical cyclones.

Such cyclones and typhoons sometimes dominate the seas with devastating forces. What is expected for navigators to ensure safe and economical voyages in such an environment? The content of this video will shed some light on this and will help to find the answers to the questions related to the navigation of the vessel in the difficult to handle conditions of the head and countering seas.

Needless to say that this instructional film will serve as a greatly useful visual aid when used as a supplement to the theoretical information obtained from the books. We recommend this one to the navigators who regularly face the necessity to handle their vessels in the above stated conditions.

All mariners are well aware of the fact that when the vessel is sailing in following and quartering seas, the vessel's motions will be augmented and this in turn will increase the possibility of the vessel getting capsized. that is why it is critically important for the safety of the vessel that the navigators possess more detailed knowledge about these risks.

The ship handling techniques that we are studying here are also available in the relevant IMO providing guidance to the Masters for avoiding potentially dangerous situations in such conditions. The content of this training video is highly recommended to the professional mariners willing to refresh or improve their skills and of course to the future ship navigators who can use it as a supplementary training source.

Proper understanding of all dangers that may be encountered in the quartering and following seas is essential to understand since it will allow to take all necessary actions and avoid the associated risks.

The PCCs, standing for the Pure Car Carriers, or Car ferries, are commonly characterized as special ships form with relatively high freeboard that have a very large area of the hull plus superstructure projecting above the water level in comparison to the area of the "underwater" hull.

Therefore, the wind has great influence on the ship hull, and the wave from the bow has also much impact on the large flare of the bow. In addition, incidents of dragging anchor due to strong winds also take place while anchoring such vessels.

We do recommend to watch this video to have better understanding of the maneuverability of the car carriers, their behavior at sea, naval architecture issues involved and precautions to be taken for the safe and efficient operation of those vessels. You may also wish to have a look in this video addressing the maneuverability of the very large ships.

When a ship navigates in head seas, it's hull is subjected to sever shocks which induce violent ship motions. As well trained and duly experienced navigators, we have the ability to provide our response to this through alteration of the course and speed of the ship to the required extent.

However, to accomplish safe navigation in head seas, it's advisable to have more reliable ship handling techniques backed by theoretical knowledge as to why these phenomena are created and what shall be done to avoid the generation of these critical effects in addition to possessing sea-going experience.

This instructional video is highly recommended to the ship navigators and particularly to the bridge teams of those vessel regularly navigating in the above mentioned conditions. By watching this video, they will find some information that will be of practical use and help them provide safe navigation of their vessels. The video will also serve as a great training tool for the newcomers and students who shall use it as a very effective supplementary training material.

Narrow passages and fairways in rivers and canals with a navigable depth or width comparatively small in relation to the draught or breadth of transiting ships are called restricted waters. The maneuverability of ships navigating through such restricted will be effected by peculiar hydrodynamic effects that are different from those when ships navigate in broad and deep waters.

Please note that we also have three other videos that belong to the same series of handling ships in restricted waters and address the anchoring, in-harbor ship handling and bank effects & interactions between two ships. The explanations are simple and clear making the video a good visual supplement to the theoretical training. Obviously, going through the content of all four videos will provide the best training effect for the mariners and is most recommended.

The content of this instructional video is intended to highlight the major effects that such passages commonly impose on maneuvering characteristics of the vessel. When the ship enters shallow water area and has either to navigate close to the banks or pass other ships, the ships of any size may get quite heavily influenced by the so-called "induced hydrodynamic effects" sometimes resulting in groundings and even ship collisions, and this is what the video focuses on.

Apart from this training video, there are three more available at Libramar addressing the anchoring, ship squat and shallow water effects, and in-harbor ship handling, all of them are equally important for the mariners so we definitely recommend all students of ship navigation and all professional mariners engaged in handling their ships in the conditions dealt with in these films, to download all of them and go through the content very carefully to get to the maximum clear understanding of the risks and how to avoid them.

In harbors and ports where maneuvering areas are confined and shallow, there are many navigational restrictions. Therefore the operators of the vessels are required to maneuver them in full accordance with the current environmental situation. Additionally, when the entering and leaving the ports also involve berthing and unberthing operations, ship handling without assistance is not easy.

This difficulty is due to the problem of directional control and coursekeeping, which, in turn, is a result of the poor steerability of the ship at low speeds combined with the influence of wind/current. This video training is a part of the four-film set.

Here at our website are the other three videos - they are devoted to the bank effects and interaction between two vessels, ship squat and shallow water effects, and anchoring issues. We definitely recommend all ship navigators to have a look in these four videos to refresh their knowledge of handling the vessels in restricted water.

In accordance with the demands of the modern industrial world for the rationalization of transporting and procuring expenses, large sized ships have been developed primarily in bulk carriers and crude oil tankers.

In particular, the cause of transportation per voyage has been reduced because wide beam very large ships have been placed and commissioned.

On the other hand, these very large ships have still more magnified the maneuvering characteristics with good turning ability but poor course keeping ability. In short, you would better watch this one if your are engaged in operation and maneuvering of the very large vessels.

Note that we have another video training film of same kind, addressing the maneuverability of the pure car carriers which is also highly recommended to watch for familiarization and training purposes.
