Offshore Supply - Dealing with Deck Cargo

Safe and successful deck cargo operations depend on everyone having a good awareness of safety. This includes the deck crew, the personnel on the bridge and the installation. Measures must be taken to minimize the hazards of any dangerous goods; the wearing of the correct PPE is essential in all loading and discharging operations. Where a color coding system is in operation for slings, the vessel should check that all slings are of correct color. The vessel will need to check that each installations cargoes are loaded together. Loads must be placed to make working with them offshore as safe and practical as possible. There must be no need to climbing on cargo units offshore.

During loading the officer on deck should check the tops of all cargo items to make certain that no loose objects, such as spanners, have been left there. The doors and lids of all cargo items must be closed and secured. Open top baskets and containers need to be checked to ensure that the contents are safely stowed and secured. Casing and drill pipes need special attention. TheyOffshore Supply - Dealing with Deck Cargo - 2 are usually loaded between deck posts and the vessels trash rail. Ideally, all these items should be capped. This is to protect the threads of pipes and stop seawater getting inside casings. Failure to do this can lead to stability problems due to the free surface effect of water inside the casings.

Where cargo is in racks, the vessel should check that all items in the rack are secured. Bolts can become loose. Dangerous goods, such as the gas cylinders, helicopter fuel, explosives and radioactive isotopes must be stowed away from accommodation with the correct separation in accordance with the provisions of the IMDG Code or national legislation. Good secure stowage is important for all cargoes as water on the deck can cause them to move. It is especially important for hazardous cargo. Different sectors have different weather working limitations. Once instructions have been received, the weather must be monitored. On a way to the installation, the lashings of the cargo should be checked from time to time, if it is safe to do so, especially if there is a lot of water on deck.

Effective Communication On Board

It is very important to understand the importance of the shipboard communications at all levels in order to achieve safe and efficient ship operation. What is communication? Here is one possible definition – transferring signals and messages from one person to another with the purpose of creating an understanding, a particular meaning or a certain reaction from the other person. If no reaction is received, we are talking about one-way communication.

According to statistics, as much as 70-80% of incidents and accidents at sea can be traced back to some kind of communication problem including those between personnel on the bridge because of different culture, native language, age, experience etc., between bridge and engine personnel, ship and tugs, ship and VTS, ship and ship owner/operator, ship and authorities.

THE TYPE XXI U-BOAT

The publication we want to offer, is actually a popular German book which was first published in 1988 as "Ubootyp XXI" - it was later translated into English language. It contains much more supplementary images than any other release of the "Anatomy of the Ship" series does, more than a hundred, and includes ones taken of the boats being built and there are also many images taken afterwards. It is also very rich with the drawings of the boats - in facts, such drawings are re-drawn versions of the original shipyard plans issued for the new construction. In fact, the design of the submarines addressed in this publication was a very serious step in the whole history of the development of the underwater vehicles.

We could say that the vessels in questions served as the prototypes of the today's conventionally powered submarines. The first boats of this design were launched in 1944. Such submarines featured a number of innovations  - for example, the schnorkel, allowing to run faster while being under the water, employing the diesel machines, and auto torpedo reload systems. Such novel design features helped these submarines in their service. The record of their brilliant service has also been provided in this publication.

Barge Carrying Vessels (Cont.)

Let us talk a bit more about the barge carrying vessels, playing a very important role in the maritime shipping industry of today, and particularly in transportation of the heavy cargoes. See the previous article for the main discussion. Here we will mainly focus on the SEABEE type of vessel, i.e. the second one.

For the SEABEE type of vessel to empty a full vessel or load a full cargo of barges, giving a theoretical loading or discharge time of 13 hours, it will actually require a theoretical cargo handling total of 64 hours for each round trip, although allowing a 50 percent margin for unforeseen delays, the total cargo handling time is expected to be about four days.

Each barge deck of the SEABEE can accommodate two barge widths, with the upper deck having a capacity for 14 barges while the main and lower decks are each suitable for twelve units, with each hold stowage area measuring 11.1 m (36.54 ft) wide by 5.9 m (19,30 ft) high. As the upper deck is free of obstructions, except in the forward area, it is possible to carry double-width barges or up to ten open-type barges with cargoes of unlimited height, i.e. restricted only by the barge stability limit. It is also possible to carry containers on the top of the upper deck standard type barges.

THE AUTOMATION AND INTEGRATION OF PRODUCTION PROCESSES IN SHIPBUILDING

The maritime shipping industry has always been of critical importance for the whole Europe, and it still is considered strategically vital to the European economy, as well as the tradition and topology, and of course tradition. Throughout the history, the shipbuilding has been treated as a significant source of employment for the people. Nowadays, shipbuilding together with the related areas, need to go through the serious changes, in order to remain competitive.

The subject changes would include, first of all, the reduction of the lead times, commonly caused by the production over-capacity and competition. It would also be necessary to achieve sustainability throughout the entire process of ship construction. In addition, the highest standards of quality shall be complied with to provide safety and environmental friendliness of the maritime navigation.

All above goals are difficult but possible to achieve but will definitely require improvements in the design and construction of the merchant fleet, as well as its subsequent technical maintenance. The newly introduced technological advances, applied to the shipbuilding industry through, for instance, the laser welding of the ship’s hull, the growing level of automation of all processes, when used properly, will eventually result in the better productivity.
