Life Cycle Assessment of Cruising Ship Superstructure - DiVA portalactivities to passengers at sea. In most cases, the cruising ship exists in steel and aluminum. To make an appropriate comparison between different materials due to economic and environmental reasons, a light weight composite material was adopted to replace the traditional steel superstructures. There are two type of structures of Norwegian Gem are to be studied: steel structure and composite sandwich material superstructure. The work is realized with the collaboration of LASS-C ...

Boat building - WikipediaFoils are usually made of lightweight carbon fibre because of its extreme strength and stiffness. Frame - the transverse structure that gives a boat its cross-sectional shape. Frames may be solid or peripheral. They may be made of wood, plywood, steel, aluminium or composite materials. They may be removed after construction to save weight or to be reused or left in-situ. In ancient shipbuilding the frames were put in after the planking but now most boats are built with the frames first.

Lightweight - Benefits of Composites | Composites Lab27 May 2015 ... lightweight. Composites materials are both strong and light. That's a winning combination. Who wouldn't want to work with a material that's simple to ship and carry? lightweight composites can save you money and manpower. Fiber-reinforced composites offer excellent strength-to-weight ratios, exceeding those of other materials. For example, carbon fiber-reinforced composites are 70 percent lighter than steel and 40 percent lighter than aluminum. Producing parts ...

Concrete ship - WikipediaConcrete ships are built of steel and ferrocement (reinforced concrete) instead of more traditional materials, such as steel or wood. The advantage of ferrocement construction is that materials are cheap and readily available, while the disadvantages are that construction labor costs are high, as are operating costs. (Ferrocement ships require thick hulls, which means extra mass to push and less space for cargo.) During the late 19th century, there were concrete river barges in Europe, ...

As a consequence, the ship hull will be more flexible and sensitive to dynamic loads. In a research project granted by the Swedish Maritime Administration, the division collaborates with. SSPA and Stena to develop the next generation of RoPax vessel, Stena Elektra, which is electricity- driven and will be made of lightweight material. The concept design is for increased energy efficiency in the maritime sector, which will be ...

Making safer composite materials for ship building - CORDIS10 Apr 2013 ... However, in 2002, a new rule in SOLAS allowed the use of materials other than steel to be used in ship building as technological advances had brought many composite materials up to the same safety levels as steel in terms of non-combustibility. With this and other legislative amendments, ship builders then began to experiment with new lightweight materials while still adhering to the strict safety rules covering the construction of passenger-carrying vessels.

Syntactic Foam and Carbon Fabric Sandwich Satisfies Hunger for ...16 Jul 2015 ... A team of researchers reports success in pioneering tests of a layered material with a lightweight metal matrix syntactic foam core that holds significant potential for automobiles, trains, and ships.

light-weight aluminium foam structures for ships - Helmholtz ...The development was driven by the requirement for increased passenger safety and the need for weight reduction in order to reduce fuel consumption. In ships the need for new materials is different. Light-weight construction is also an important issue but other aspects gain importance as compared with the automotive sector. More flexibility of materials processing, e.g., is required because ships are not built with highly standardised parts but the material is processed during building.

JAPAN INSULATION has obtained ISO 9001 ...

Tonnage - WikipediaTonnage is a measure of the cargo-carrying capacity of a ship. The term derives from the taxation paid on tuns or casks of wine. In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship. Tonnage should not be confused with displacement, which refers to the actual weight of the vessel. Tonnage is commonly used to assess fees on commercial shipping.

NASA - The Right Stuff for Super Spaceships16 Sep 2002 ... Should one of these sand- to pebble-sized objects puncture the ship's armor, a layer of self-healing material would keep the cabin airtight. Meteoroids aren't the only hazard; space is filled with radiation, too. ... So if our spacecraft of the future already uses nanotubes as an ultra-lightweight structural material, could those tubes also be loaded up with hydrogen to serve as radiation shielding? Scientists are looking into the possibility. Left: When high-energy cosmic rays ...

Ship construction | Britannica.comWith the rapid growth and development of the physical sciences, beginning in the early 19th century, it was inevitable that hydrokinetics (the study of fluids in motion), hydrostatics (the study of fluids at rest), and the science of materials and structures should augment the shipbuilder's skill. The consequence of this ... The designer must choose dimensions such that the displacement of the vessel is equal to the sum of the deadweight and the lightweight tonnages. The fineness of the hull ...

More efficient ship designs Modern design techniques like CFD (computational fluid dynamics) create ships that slip through the water more efficiently. Less resistance means lower fuel consumption. lightweight materials If a vessels weighs less for a given size, it needs less power to drive it. Steel is still the material of necessity for larger vessels, but aluminium and the increasing use of composite materials in ...

Part 1: How to Design a More Efficient Ship gCaptain4 Jan 2012 ... lightweight ship construction shipping efficiency. The use of lightweight structures can reduce the ship weight. In structures that do not contribute to ship global strength, the use of aluminium or some other lightweight material may be an attractive solution. The weight of the steel structure can also be reduced. In a conventional ship, the steel weight can be lowered by 5-20%, depending on the amount of high tensile steel already in use. A 20% reduction in steel weight ...

Estimation of Ship Lightweight Reduction by Means of Application of ...Faculty of Mechanical Engineering. Estimation of ship lightweight. Reduction by Means of Application of. Sandwich Plate System. Sandwich plate system is an alternative to conventional stiffened plate composition that consists of two metal plates separated by an elastomer core. Considering high strength to weight ratio, simplicity, blast and ballistic properties of the material, SPS has been widely used in a range of industries but its most dominant application has become ship repair.
