The present study deals with the feasibility to implement, on board ship, a direct nanofiltration process in order to treat laundry grey waters and recycle 80% to the inlets of the washing machines. At first, a specific methodology for real laundry grey water production was set up at the laboratory for the purpose. Characteristics of the lab-produced grey water are close to those observed on board (pH 7, 1300 mg COD/L, 80 mg TSS/L). Then, a membrane screening in view of a selection was realised at the lab scale. A direct nanofiltration process (without pre-treatment) on tubular PCI-AFC80 membrane (35 bar, 25 °C, volumic-reduction-factor 5) allowed us to produce a permeate free of micro-organisms and suspended solids and with only 48 mg COD/L and 7 mg TOC/L. Based on these satisfactory preliminary results, a techno-economic study was conducted (up-scaling) with the aim of producing daily 52 m 3 of recyclable permeate from 65 m 3 of polluted grey water. Finally, orders of magnitude, both for energetic consumption and processing costs, are proposed. © 2010 Elsevier B.V. All rights reserved. Source

The present study completes a previous work dedicated to the feasibility to implement, on-board ship, a direct nanofiltration process in order to treat laundry greywaters and recycle 80% to the inlets of the washing machines (Guilbaud et al., 2010). At present, the study investigates the influence of nanofiltration operating conditions on Chemical Oxygen Demand (COD) rejection rates and permeates fluxes. Thus, the pH and temperature of greywater as well as transmembrane pressure have been fixed to 7 or 9, 25 or 40°C and 35 or 40 bar, respectively. AFC80 membranes show different COD rejection rates whereas permeate fluxes are quasi similar when the same greywater (pH 7) is nanofiltered at 35 bar and 25°C. Amongst all the tested operating conditions, the nanofiltration of greywater (pH 7) on AFC80 membrane, at 35 bar and 25°C, allows to obtain the highest COD rejection rate (around 93% at VRF5). The best permeate flux (85.5 L/h/m 2 at VRF5) has been obtained at 40 bar and 40°C. An increase of temperature or pressure above 25°C and 35 bar respectively leads to a drop of COD rejection rates. The pH should be maintained at a value of 7, the initial pH of raw greywater, in order to allow a good COD rejection rate. An economic evaluation of greywater nanofiltration has been investigated. © 2012 Elsevier B.V. All rights reserved. Source

The application of goal base safety philosophy in the design of the world's largest cruise ship 'Oasis of the Seas' is discussed. The ship was designed and built by STX Europe for Royal Caribbean International in 2009. The goal-based ship standards are developed on the basis of a five-tier system, consisting of goals, functional requirements, verification and acceptance criteria, rules and regulations for ship design and construction and industry procedures and quality systems. Outdoor spaces between the split superstructures introduced a new fire safety concern. Fire loads were simulated and different solutions tested to demonstrate equal safety with SOLAS. Fire break areas were introduced in the lay out to slow down spread of fire. The IMO new rule also requires that passengers and crew in the case of casualty can stay onboard as the ship proceeds to port. This demands a redundant power supply and propulsion. All control system onboard should support and guide the crew the day to day operation, but especially when accidents or causalities demand special actions. Source
