The strength of any boat and ships is one of the key interests of many architects and shipbuilders. Ships are required to be designed and built with quality and strong materials to avoid any chances of sinking, especially during heavy conditions. However, if they are built with those materials, they will also travel heavy, slow and cost too much to operate. They also weigh more. Ships built poorly may also result to minor and major damages.

The hulls of the boats are typically subjected to different loads, even witting on the anchor or dockside. This is because the pressure of the water will be displaced by the ship as it exerts pressure to the hulls. The high strength hull steel is very important for the structure of every ship. That is why cargoes and other equipment are distributed fairly to each side of the ship as it sails to its destination.

Today, modern ships are almost designed and built of steel Shipbuilders also use steels because it has good corrosion resistance when exposed to seawater and do not break easily at low temperatures, since sailing ships during cold storms in winter time can cope up with the temperature and those boats built poorly may only cause failures and cracks.

Basically, steels have a certain fatigue that causes metal failures and cracks. Most of the safety factor can be applied to the yield strength. A boat designed and built with the basic concept and criteria usually assumed that it can operate with fully loaded materials in strong waves and heavy weather.

Hull structure design has recently become more important. It has always been considered, technically and economically to be an important factor of the shipyard management, since the strength of the ship is the main concern and the cost of the hull steel is the total cost of the ship. Thus, the need for talented and skillful designers is in demand to assist the hull structure design.

When the ship is sailing, it is subjected to several load patterns with various magnitudes which may cause some deformations in the structure and stresses. The occurrence of many structures may determine the structure features, the distribution pattern, direction of workload and frequency as possible.

There are also diversities that happen in several types of design styles, types of hulls and expanding array of construction materials. Hence, it would be hard for the surveyors to keep on certain evaluations. So, whether the surveyor deals with related marine experts and professionals, learning the best ways to locate, detect and evaluate is still a critical factor to consider for surveyors.

Improper selection of design and use of these materials may also result to non damage structural failures. The manufacturing defects may also figure out all failures in the structure. Once it makes a certain impact to the water, it may also stresses the work to buckle transversely.

In many operations even in heavy conditions, the sides of the ships will also deflect to lesser or greater degrees based on how they are designed and made. It is necessary for the ships to be built with quality, so they can sail more evenly even during heavy conditions.
