1. 1. CFD Simulations of Unsteady LHA Ship Airwake in OpenFOAM

   University essay from KTH/Mekanik

   Author : Matus Cvengros; [2018]
   Keywords : ;

   Abstract : Extensive research in the past two decades has shown that flow around the sharp edges of bluff bodies, such as the superstructure of a ship, can cause large scale shear-layer separations with increased turbulence, generating a highly unsteady flow in the airwake region. Such separations affect the control margins and handling loading of a rotorcraft, mainly if operating from the vicinity of a flight deck, and therefore negatively influence the rotorcraft operating limits, which is one of the main reasons for the study of ship airwakes.

3. 2. Modeling the effect of the use of fiber reinforced plastics on the evacuation of a ro-pax passenger deck

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Andres Rodriguez Panagiotopoulos; [2014]
   Keywords : Fire safety; Fiber reinforced plastics; ship; FDS EVAC; evacuation; Technology and Engineering;

   Abstract : Modern ship design and construction is striving to make sea transportation more fuel efficient and more environmentally friendly. One of the possible solutions is to make the ships lighter by reducing the weight of the superstructure, constructing it completely or partially with lightweight materials such as Fiber Reinforced Plastics (FRP), like glass fiber composites or carbon fiber composites.

4. 3. Life Cycle Assessment of Cruising Ship Superstructure

   University essay from Institutionen för geovetenskaper

   Author : Qianqian Hou; [2011]
   Keywords : Sustainable development; Life cycle assessment; composite material; ship superstructure; environmental impacts;

   Abstract : This thesis project was conducted to compare the environmental impacts between two types of material for a superstructure of cruising ship (Norwegian Gem) using life cycle assessment (LCA) methods. With the increasing price of industrial raw materials and finite resources, more and more corporations or manufacturers endeavor in seeking more economical materials and less environmental impacts within the ship building field.

5. 4. Java Application for Analysis of Lightweight Constructions in Cruise Vessels

   University essay from Institutionen för informationsteknologi

   Author : Erik Hedin; Johannes Lundsten; [2010]
   Keywords : Fire spread; tool; java; analysis; simulation; exhaustive testing; network; sectioning device;

   Abstract : In 2002 an amendment was added to the International Convention for the Safety of Life at Sea (SOLAS) which opened up for shipbuilders to replace steel with lightweight materials in the superstructures. However, SOLAS requires equal fire safety compared to ships with steel superstructures. READ MORE

6. 5. Assessing Fire Safety in Maritime Composite Superstructures –- A Risk-Based Approach

   University essay from Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Brandingenjörsprogrammet; Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Author : Franz Evegren; [2010]
   Keywords : Composite; fire safety; ship; risk-based; risk analysis; maritime; risk assessment; Technology and Engineering;

   Abstract : Reduced weight and maintenance make it advantageous to replace steel with Fibre Reinforced Polymer (FRP) composites in maritime applications, but being combustible makes fire safety a burning issue. A new methodology in regulations has opened up for innovative design solutions if they can be regarded as safe as a design complying with all prescriptive requirements. READ MORE
