Jumbo shipping

Jumbo Shipping or Kahn Shipping is a company who specializes in heavy marine transport.

Introduction

Transporting special heavy cargo by sea has for decades been something that Dutch companies are involved with. Mr. Kahn, the father of the current director, founded in 1968, Jumbo Shipping on when containerization began. His motto was: not everything fits into a box, and he was right. The family business is a leader in heavy and special transports with a fleet of 12 specially designed ships. The lifting capacity of these giants ranging from 500 tonnes to 1800 tonnes of the new J-class vessels. The fleet has been around since the beginning as the home port of Rotterdam, and there is also the headquarters.

History

In 1956 was the first time Stella purchased a coaster for that time with four heavy 12-ton derricks. The Prima Stella proved a success. Heavy items so far are dangers payload on the deck of a coaster, could now be better equipped ships transported. However, with time and increased understanding, the documents load heavier and more voluminous. In 1967, the first purpose-built heavy lift ship ordered. In 1968 was Jumbo's A-Class was introduced, when the NovaS tella was transferred by the Zaanlandse Shipbuilding Company. In 1969 followed by two sister ships in the same class. The experiences gained in the years thereafter, were incorporated into a new class, the B-class in 1974 was taken into service. Jumbo currently has two ships under construction, the J-1800 class. Of this series have been two ships in service since the year 2004. In the year 2008 there will be 4. The lifting capacity increased from 100 tons to 1800 tons in 38 years.

The beginning of a major transport project

A major transportation project often starts with contact between a client and a employee of Jumbo. At such fairs and meetings discussed the possibilities. Jumbo's headquarters to Rotterdam daily transportation applications within the commercial department. Part of it comes through agents around the world. Here is an initial estimate that the project can be adopted, the degree of difficulty, and whether there is space on one of the vessels.

The commercial department works closely with an engineer inquiry, the application closer look. Examines in detail how the load can be transported, how complicated the preparation and execution, and how many man hours and resources it will include. Based on this study, along with other customer requirements such as the desired flexibility in planning, commercial department, the customer an offer. It can then decide whether or not in Jumbo sea. If the client agrees, it is signed and shipment scheduled. Scheduling of heavy transport vessels is a complex puzzle with the variety of projects and destinations.

Engineering

Once the contract is signed, the responsible project engineer and starts talking AbOUT the technical preparations. The first thing he looks at where the cargo can be placed, and what the loading and unloading sequence With more bulky loads is often a complicated puzzle that is usually done with CAD software. The most convenient stowage position can not always be achieved by restrictions on the crane or load. The limitations include: the crane capacity at a certain range, the available lifting height and the space between the boom and the load. The next part of the project engineering, the stability of the ship at sea. This is subject to certain requirements. The GM value for this is the measure is strongly influenced by the weight and height of the gravity of the load. Equally important, however, the stability during lifting. This limits the maximum angle of the jib of the crane, but the maximum range of the crane. In order to increase stability when lifting a pontoon stabilization on the side of the vessel be secured. For complex jobs with small margins are regularly 3D simulations done to obtain better insight into the operation.

Work preparation

After the completion of technical preparations, the operations department with the help of the cargo inspector to work with the further organization and planning. Agents and stevedores are engaged and preparing the ship, the docks and the load are planned. The documents to be trimmed, and all parties are kept informed of the latest timetable. For the success of complex transportation projects such as Jumbo executing them is important that each party the right information at the right time will be delivered. In addition, a tight schedule of great importance to a project go smoothly.

Implementation

After a thorough preparation is the responsibility of the crew of ships to carry out the project, and to a successful conclusion. The crew aboard the ships of Jumbo comprises between 14 and 20 people. A standard crew consists of one captain, three mates, three engineers, a boatswain, a craftsman, a number of sailors and a cook. The captain has overall control of the vessel, and is responsible for stability, heavy lifting and administration. The first officer has operational control board, assists in lifting the captain, and is responsible for the organization on deck. He also coordinates the rigging and lifting gear zeevasten. The second mate again assists the first mate, and does well as a safety officer continued on safety. Finally, controls the second mate while lifting the ballast system. The third mate assist the first and second mate, where necessary, and is often involved in cargo handling and ballasting at sea provide these officers when navigating on their guard services, and keep them engaged in such maintenance of the vessel and property, cargo inspection trip preparation and maintaining nautical charts and logs.

The chief engineer aboard the technical direction and coordinate the team engineers. The officers on board a ship Jumbo allround techies. They solve problems and provide maintenance of all equipment on board. These are all types of pneumatic systems to power. The mechanics work in CONTRAST to the day shift officers and mainly control tasks. The engine is indeed fully automated.

Jumbo Logistics

Besides transporting large cargo from quay to quay Jumbo also offers the option to charge from "door to door transport. Jumbo Logistics division provides pre-and after transport from factory to building site. This may eg pontoons, heavy truck and trailer combinations or self-propelled trailers meerwiellige used. Before a transportation takes place, the process investigated. If necessary, additional supported bridges, widened roads, or temporary ports constructed.

Jumbo Offshore

The latest J-class heavy transport ships were not only capable of carrying the heaviest load. The transportation and offshore installation of offshore installations can be performed with these ships. An advantage of the use of Jumbo's ships is that all the equipment on its deck can be transported, and that vulnerable installations tweekraans a lifting operation can be placed. Because this is not considered necessary to the ship movements of a crane ship as both a transporter, can also be worked through a rough sea. Especially for offshore projects, 2 of 4 J Class ships equipped with a dynamic positioning system that keeps the ships in place during the work.
