Marine Structures

MAADI Group designs and manufactures your ferry landing or maritime structures according to national and international design codes. Our strong background in the shipbuilding and ship design industries puts us at the forefront to engineer any maritime structures. We are able to provide full engineering services for your project

Evaluation of mooring and anchoring loads

Mooring loads comprise those loads imposed on a maritime structure by a vessel tied up alongside, both through contact between the vessel and structure or its fendering system, and through tension in mooring ropes. Mooring loads in harbors and sheltered anchorages are principally caused by winds and currents. We can design your floating structure anchoring system in shallow or deep waters in order to sustain any wind or current velocities.

Evaluation of berthing loads

In the course of berthing a vessel, loads will be generated between the vessel and the berthing structure from the moment when contact is first made, until the vessel is finally brought to rest. The magnitude of the loads will depend not only on the size and velocity of the vessel, but also on the nature of the structure, including any fendering, and the degree of resilience they present under impact.

Evaluation of gravity loads, buoyancy and static stability (Naval Architecture)

Live load includes the loads specified by maritime codes for various uses (restricted or unrestricted access) and occupancies of the floating structure. These specified loads cover the occupants and any movable equipment. Dead load includes self-weight of the structure and its services such as electrical cables and water supply. Minimum buoyancy is what makes the maritime structure continue to float in water when fully loaded. A maritime structure is stable when it floats upright in still water and returns to its initial upright position if given a slight, temporary deflection to either side by some external force.

Floating Breakwaters

Almost any wave can be stopped with a stone breakwater; however, this is not always a feasible or cost effective method. The selected method of wave attenuation will be heavily dependent not only on the wave periods, but also on the water depth. Water depth is important because of the physics of the wave power’s vertical distribution in different water depths. That is the reason why some attenuation methods work better in deeper water, while other methods apply strictly to shallow water areas.

The use of floating breakwaters as temporary or permanent coastal structures has become increasingly widespread in North America. MAADI Group has developed expertise and field experience with floating breakwaters, designing successful innovations that are relatively inexpensive for suppressing waves.

The primary advantages of MAADI Group’s floating breakwater system are the following:

Economy of material
Freedom from foundation problems
Freedom from erosion problems
Indifference to tidal changes in site water depth
Probable relative ease of transportation
Creation of additional boat slips and dockage area

The relative damage to a floating structure is a function of the amount of energy expended by the wave front upon impact. This function is not easily measured, but may be calculated as the sum of the potential and kinetic energy.

MAADI Group is able to design and manufacture your floating breakwater or wave attenuator based on our analytical and experimental work that has been undertaken for a number of years. Our strong background in the shipbuilding and ship design industries puts us a step forward in the engineering of any maritime structures.
