Appraisal of Lightweight Moorings for Deep Water
This paper outlines the potential advantages of using lightweight fiber ropes for mooring floating production platforms. The influence of tether properties on mooring system response is discussed. It is...

Leveraging Technology: The Use of a Company Intranet and Portal Technology to Improve Productivity and Quality
This session will provide a case study on how Walter P. Moore and Associates is leveraging technology to improve productivity and quality. The session will focus on two technologies, a...

Succession Planning Pays Off
If your company hasn't yet put a plan in place to transition from its current ownership and leadership to the next generation, now is the time to start. When planning to offer...

Let the Buyer (and Seller) Beware
A merger or acquisition shouldn't be a gamble, but many firms depend too much on good luck and good will. For long-term success, the best bet is a checklist for professional...

A Comparison of Three Wave-Measuring Buoys
We compare the performance of three wave-measuring buoys: a Seatex Wavescan^TM, an Endeco/YSI Wavetrack^TM,...

Nonlinear Dynamic Analysis of Single Point Moored Buoy Under Wave and Current Loadings
In this study, a single point moored spherical buoy under wave and current loadings is analyzed in the time domain considering time memory effects. Geometric nonlinearity of the mooring...

Case Study ? Elliott Bay Marina Floating Moorage
The recently completed Elliott Bay Marina project in Seattle is one of the larger projects of this type in the country, with 1196 slips ranging from 32 feet to 60 feet, a floating fuel...

Results of a Monitoring Program of Moored Ship Response to Gravity and Infragravity Waves
An automated monitoring system was designed and operated at a coal terminal in Los Angeles Harbor, and a container terminal in Long Beach Harbor, to obtain the complete six degree-of-freedom...

Los Angeles-Long Beach Harbors Model Enhancement Program
In response to the expansion of oceanborne world commerce, the Ports of Los Angeles and Long Beach, California, in coordination with the Los Angeles District of the U.S. Army Corps of...

Measured and Simulated Response of a Small Semisubmersible Moored in Deep Water
Small semisubmersible platform concepts are proposed for electronic tracking ranges, single-well petroleum production, and oceanographic data collection. This paper summarizes a major...

Flexible Membrane Wave Barrier
A linear analytical model is developed for the dynamic response of a flexible membrane wave barrier. The wave barrier consists of a thin flexible membrane suspended in the water column...

Broadside Current Forces on Moored Ships
A method of estimating the static lateral current force on ships in deep and finite depth water is presented for the case of the current broadside to the ship. The method is based on recent...

Hydrodynamics of Deepwater Tension Leg Platforms
A model is presented for investigating the overall quasi-static behavior of tethers, the anchoring elements for a Tension Leg Platform, TLP. Effects of tether weight and curvature, and...

Moored Systems for Time Series Observations of Bio-optical and Physical Variability in the Coastal Ocean
Recently, multivariable moored systems (MVMS) have been developed to study the ecology and physics of the upper ocean. Concurrent MVMS measurements provide time series of beam attenuation...

Port Layout Optimization for Large Bulk Carriers in a Strong Tidal Currents Site
To provide the sheltering conditions of Ponta da Madeira Terminal (TPM) in Sao Marcos Bay, in Sao Luis, Brasil, two rubble mound groins were designed and constructed according to hydraulic...

Loss-Reduction for Lifelines in a Federal Earthquake Insurance Context: Some Preliminary Issues
Through a two-year project, Dames & Moore has examined the topic of building or landuse loss-reduction measures in a federal earthquake insurance or reinsurance program. Loss reduction...

Avalon Harbor: Example of a Successful Destination Harbor
Avalon Harbor, which is located on the southeast side of Catalina Island approximately 25 miles (40 km) off the coast of Southern California, is an excellent example of a destination harbor...

Avalon Harbor Utilization
Avalon Harbor is a destination resort harbor which serves the Southern California boating community and recreation public. The harbor is a roadstead mooring in a partially protected cove....

Collision Risk Analysis Fixed Platform and Semisubmersible
This paper summarizes the North Sea experience pertaining to mooring line failures of conventional 8 and 12 anchor line systems. Mooring system calculations, experience and test results...

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...
