Mariner Hull

Rieliter et al. (1997) used this teehnique to model the dynamie eharaeteristies of a ship. The vessel was based on the Mariner Hull and had a length of 161m and a displaeement of 17 000 tonnes. The training data was provided by a three degree-of-freedom (forward veloeity, or surge, lateral veloeity, or sway and turn, or...

Two-pack Epoxy/polyamine or polyamide Tank linings Marine hull paints Ketones (glycol ethers) alcohols aromatic hydrocarbons The appropriate combination of alcohol/aromatic can act as a true solvent. Brush applied systems are prone to retain high boiling solvents This may affect performance especially water resistance. 

On the other hand, hollow glass spheres, which were developed by 3M in the 1960s, are widely used in aerospace and automotive systems, paints and coatings, marine hulls, and oil and gas exploration and production. Microglass bubbles are made... 

As an example of the effect that corrosion can have on connnercial industries, consider the corrosive effects of salt water on a seagoing vessel. Corrosion can drastically affect a ship s perfonnance and fiiel consumption over a period of time. As the hull of a steel boat becomes corroded and fouled by marine growths, the... 

Cathodic Protection Systems. Metal anodes using either platinum [7440-06 ] metal or precious metal oxide coatings on titanium, niobium [7440-03-17, or tantalum [7440-25-7] substrates are extensively used for impressed current cathodic protection systems. A prime appHcation is the use of platinum-coated titanium anodes for protection of the hulls of marine vessels. The controUed feature of these systems has created an attractive alternative... 

System parameters The ship to be eontrolled is a eargo vessel of length 161m with a MARINER type hull of total displaeement 17 000 tonnes. 

Typical marine propellers are fixed pitch and small in diameter with veiy thin, but broad, blade sections. They are made from either cast metal, corrosion-resistant metal alloys such as copper, or composite materials. Marine propellers normally operate at 60 percent efficiency due to the proximity of the ship s hull, which limits the overall diameter of the propeller and disturbs the efficient flow of water through the blades. As a result, the blades have to be veiy wide to produce adequate thrust. Marine propeller designers use innovations such as overlapping blades and wheel vanes to offset those problems and improve efficiency. 

The primary UPR end markets are construction, automotive, and marine industries widi applications such as house paneling, tub and shower applications, chemical-resistant storage tanks, pultruded profiles, and fiberglass composite boat hulls. The UPR industry is mature, with a world production close to 1.7 million tons (Table 2.2), but must face two important issues increasingly strict regulations for styrene emissions and poor recycling potential for polyester thermosets.48 49... 

Unsaturated polyester resins based on maleic anhydride are widely used in coatings to manufacture boat hulls and truck caps and a variety of other uses where a smooth, weatherproof, hard-surfaced material is desired. Because these resin types are inherently brittle, hberglass is frequently added for reinforcement. Consumphon of unsaturated polyesters in the U.S. is well over a billion pounds per year, with about 50% going into construction and the marine industry.
