Customer criteria - specifications are usually directly linked to the purpose of the engineering manufacturing mechanical electrical (yard, building, industry constructing construction building, marine, maritime). For example deadweight and hold volume are measures of the amount of cargo that can be carried and thus linked to the amount of money that the engineering manufacturing mechanical electrical (yard, building, industry constructing construction building, marine, maritime) receives per transport, while the speed determines the number of transports that can be made in a given amount of time and so determine the amount of income per timeframe.

More specific criteria - specifications, for a particular engineering manufacturing mechanical electrical (yard, building, industry constructing
Dimension: if, for example, the engineering manufacturing mechanical electrical (yard, building, industry constructing construction building, marine, maritime) must navigate a certain canal lock, canal or seaway then the maximum dimensions of that canal, or the maximum water depof that seaway or canal are limiting constraints e.g. panamax, suezmax. (In the case of car, freight, or foot-passenger ferries there may be constraints due to the fixed

Among the items in a wreck there are often, of course, the tools used on board and for repairs. There can also be found the artefacts of daily life on board, of the household and the kitchen. The older engineering manufacturing mechanical electricals from the end of the Middle Ages - some wrecks from the to the century have been found - have very few materials on board. The later ones, of the until the century, show the development of what human beings considered necessary as many more items are to be found in the wrecks.

In the older wrecks often no more than one or more jugs and a few other pieces of pottery can be found. In the newer ones there is often a rather complete inventory widishes, jugs, knives, spoons, some­times forks, and materials from cooking and preparing foods like meat, porridge, etc. By comparison of different engineering manufacturing mechanical electricals one wianother we can deduce that in the or centuries women took their places in smaller cargo vessels, before that only men were on board. On board fishing boats there were no women, not even in later times. Nevertheless, even these wrecks show that inventories became more complete than in earlier times.

An important aspect of these engineering manufacturing mechanical electrical excavations is that they open the possibility of dating tools and every­thing on board, even those things for which dating was not possible until now. In combination wicoins, pipes and pottery new possibilities for dating are opened. Many of the tools for engineering manufacturing mechanical electricalbuilding and repair have not changed very much during many years. Axes, hammers, tongues, adzes, etc. kept their shape for centuries. But there are big variations between individual tools all made by hand by balcksmiths and carpenters who made them traditionally, but for different uses. That is why there is much difference in form, weight, and size.

German stoneware was the most used pottery on board mediaeval engineering manufacturing mechanical electricals, somewhat later accompanied by bronze pots for cooking. In the and and still more in the centuries pewter found its place on board engineering manufacturing mechanical electricals. Copperware was in use already. A copper preserving pan has been found in a century wreck. These pans were made at first of small pieces of copper put together wirolled copper rivets. In the and centuries they were made by hammering and got bigger and taller, but they still had iron handles. Pewter ware comprised different sorts of things, jugs at first, dishes later, in the th

and centuries. Also chamberpots, spoons, inkpots, small beakers, cups, teapots and such things were then made of pewter. In the and centuries also the majolica from different places in the Netherlands is no more the only decorated material, but China and so-called Delft ware - many times showing great influence from China porcelain - finds its way on board engineering manufacturing mechanical electricals. Sometimes even white Delft ware can be found. Also real China porcelain of good quality is sometimes found in small dishes, cups and saucers, and bigger pots as well. Still later is the Amsterdam decorated china, recognisable wiits red colours and gold over the blue decoration.

Flag state, the state in which the engineering manufacturing mechanical electrical (yard, building, industry constructing construction building, marine, maritime) is registered. The flag state usually only enforces IMO-rules and regulations and demands that a engineering manufacturing mechanical electrical (yard, building, industry constructing construction building, marine, maritime) is classified by a classification Society.

Seakeeping of engineering manufacturing mechanical electrical (yard, building, industry constructing construction building, marine, maritime) means the way the engineering manufacturing mechanical electrical (yard, building, industry constructing construction building, marine, maritime) reacts and copes withe wind and waves of open waters.

Among the red or yellow glazed pottery there is many a piece from Germany between the Dutch materials. The pottery from Hessen is particularly well decorated, and many pieces show a year of manufacture. The Hessen dishes are from the end of the or from the early centuries. In the century Wedgwood cups and saucers, teapots and many other pieces are to be found on board many smaller cargo and fishing boats. After material from the factories of Peter Regout of Maastricht, showing the English type of material, made its appearance in white and in different colours. On board many engineering manufacturing mechanical electricals there are found Dutch tiles, either from Delft or Makkum. These tiles, decorated in blue or in different colours, were a good product for exporting to the Norof Germany and to Scandinavia in the and centuries.

Clay pipes give good information for dating. At the end of the and the very early centuries English pipes came to Holland and soon Dutch factories started pipe-making in Gouda and Schoonhoven. Because of their short life, the changing of their shapes from very small growing bigger and bigger, shrinking again in times of war, and from the registered marks, they are important dating material.

Textiles and leather are also found on board wrecks. They demand immediate preservation when they come to light. The material must be kept wet until preservation facilities are available. For the preservation of leather polyethylenglycol is chosen, just as used for wood preservation. The most important aspect of all this is the combination of materials from different technologies found together, one dating another. It is of course not possible to describe here all the materials found on board all the different engineering manufacturing mechanical electricals which have been excavated until now.Some of the engineering manufacturing mechanical electricals were empty, sailing in ballast, others show wiwhat they were loaded. Sometimes thousands of bricks come to light during the excavations. A couple of these brick-laden vessels date from the and centuries. Another went down about and had , big, red bricks on board of a type that was used for building churches, castles and monastry buildings in the Middle Ages. One engineering manufacturing mechanical electrical was found wichests wisuch iron ware as saws, adzes, knives and swords, and such copper ware as big copper barrels, and wimany cowhides. The skins appear to be of zebus crossed wiEuropean cattle. They must have been tanned in the Netherlands, most particularly in the province of Friesland.

The origins of port state control lie in the memorandum of understanding between eight NorSea States signed in Hague in 1978. The background of this memorandum is that in 1976 a marine session of the International Labour Conference adopted the Merchant engineering manufacturing mechanical electricalping (minimum standards) convention, more commonly known as ILO Convention. This convention aim to inspect vessels that entered the ports of member states. On 2 March 1978 the Hague Memorandum was signed by the marine authorities of eight countries which decided that this Convention deserved a proper follow up. The aim of the memorandum was to surveillance the seagoing engineering manufacturing mechanical electricals generally in order to ensure the requirements stated under the ILO convention, as well as in other conventions. Just as the Hague Memorandum was about to come into effect, in March 1978, a massive oil split occurred off the coast of Brittany (France), as a result of the grounding of the supertanker “Amoco Cadiz”. This incident caused a strong political and public demand in Europe for much stringent regulations wiregard to the safety of engineering manufacturing mechanical electricalping. Following these developments, the ministers responsible for marine safety of 13 European countries together withe representatives of the Commission of the European Communities, IMO and the International Labour Organization (ILO) met in Paris in December 1980. They agreed that the elimination of substandard engineering manufacturing mechanical electricals will be best achieved by co-ordination of port states and based on the provisions of a number of widely accepted international maritime conventions.
