A cost-effective robotic solution for the cleaning of ships' hulls

Controlling Marine Fouling with Antifouling Paints and Underwater Hull Cleaning

trolling marine fouling on ships’ hulls has been considered essential since the earliest days of marine transport. It has been estimated that without any attempt to control fouling, shipping would require 40% more power, equal to about 72 million tonnes of additional fuel per year.1 Therefore, without an effective antifouling system, today’s marine transport industry would undoubtedly grind to ...

Self-traveling robotic system for autonomous abrasive blast cleaning in double-hulled structures of ships

Technical Note: An opportunity cost maintenance scheduling framework for a fleet of ships: A case study

The conventional method towards deriving schedule for a fleet of ships to minimize cost alone has the short-coming of not addressing the problem of operation revenue losses associated with delays during maintenance at ships dockyards. In this paper, a preventive maintenance schedule for a fleet of ships that incorporates op-portunity cost is presented. The idea is to assign a penalty cost to al...

The Most Cost Effective Gas Cleaning Device in Steel Industry with Industrial Ecology Approach

Industrial growth and environmental damages, as two important indicators in sustainable development are followed by steel industry. This article leads industries to green industry. In this case, energy, material, capital consumption and environmental damages as sustainability patterns of environment have been investigated in three different dust collectors to select the most environmentally sui...

A Comparative Study for the Removal of Methylene Blue Dye from Aqueous Solution by Novel Activated Carbon Based Adsorbents

This study was conducted to assess the ability of the studied adsorbent, i.e. raw oak fruit hulls and the activated carbon prepared from oak fruit hull for removing the Methylene blue (MB) from aqueous solution. This study was conducted under various effective parameters, e.g., contact time, pH, MB concentration, adsorbent concentration. The optimum amount of each parameter was determined a...
