Analytical Method of Ship Motions Moored to Quay Walls and Application to Port Planning
This paper describes an analytical method to calculate ship motions moored to quay walls and application of the method in order to establish the port planning method in taking account...
Evaluating LNG As a Fuel for Diesel Shrimp Boats
Liquefied Natural Gas (LNG) is being evaluated as a viable fuel for diesel engines. A shrimp boat is being used to evaluate the LNG system. LNG has an economic advantage to diesel fuel;...
Implementation of Annex II to Marpol 73/78 and the Impact on Reducing Pollution in the Coastal Zone

New Tools for Economic Evaluation of Channel Deepening Projects
The Institute for Water Resources has developed a data base to facilitate economic evaluation of channel deepening projects. After extensive research, data elements were selected from...
Current Research Efforts in Determining the Effects of Tributyltin Use in Marine Paints in the Chesapeake Bay Estuary
In the mid-seventies, manufacturers of marine paint began to use a tin-based biocide called tributyltin or TBT. TBT has been found to be very effective in slowing the biofouling process....
Oil Pollution in Suexz Gulf of the Red Sea
The population along the Red Sea coast is small, but this sea is now one of the most important areas in the world, for it is the route for ships using the Suez Canal. Many vessels transit...
Design of Waste Containment Structures
Synthetic liners, also known as flexible membrane liners (FMLs), have been used increasingly since the early 1970s to contain chemical and hazardous wastes because of their low permeability...
Chemical Effects on Clay Hydraulic Conductivity
Hydraulic conductivity and its susceptibility to changes with time or exposure to chemicals are major factors in selection of clay for use in waste containment barriers. Available concepts...
Vertical Barriers in Soil for Pollution Containment
Vertical barriers have evolved over the past fifteen years into a technique that is widely applied to restrict the underground movement of liquid wastes and polluted groundwater. Most...
Fly Ash as a Potential Waste Liner
Earthen liners have been widely used to contain toxic and hazardous materials in ponds and landfills. There is close scrutiny over the durability of liners in contact with various wastes...
Evaluation of Compacted Inert Paper Solids as a Cover Material
The following paper presents the results of a laboratory test program which focused on compacted sludges or inert paper solids (IPS) as recommended cover (cap) material over existing IPS...
Thickened Slurry Disposal Method for Process Tailings
Common practice in the disposal of process tailings consists of impounding the wastes as thin slurries or suspensions in diked containment areas. Such a procedure poses problems relating...
Design of Bridge Piers Against Ship Collision
Design rules for unprotected bridge piers, using uniform safety requirements, are proposed. The selection of an appropriate design vessel is based on a risk assessment model which uses...
Sunshine Skyway Ship Collision Criteria
The 'new' crossing of Sunshine Skyway was born, not only to replace the previous crossings and improve the regional economy but also with increased clearances...
A Simulation/Animation of an Inland Railway Container Terminal
The Container Terminal Model (CTM) comprises a batch computer simulation model and interactive graphics animation package. The model has been developed to aid engineers and transportation...
Geosynthetics Unearthing New Applications
Geosynthetics are now a $700 million industry. Called geomembranes, geotextiles, geogrids and geocomposites, geosynthetics complement or replace geotechnical designs. Five case studies...
Drilling Unit Approval and Sea Ice, Alaska OCS
This paper describes types of ice conditions that have been, or could be, encountered while conducting Alaska Outer Continental Shelf (OCS) operations. The types of ice monitoring programs,...
Repair Welding of Arctic Offshore Structures and Vessels
This paper describes the welding procedure development for repair or field modifications of offshore drilling structures and vessels made with several different steel grades produced for...
Permafrost: A Suitable Landfill Containment Barrier
Ice-rich permafrost is a suitable medium for the containment of wastes. The combination of frigid dry Arctic climate and the impermeability of ice-cemented permanently frozen ground can...
Future Containerships from a Ship Owner's Viewpoint
