Application of a Beach Plan Evolution Model in Sergipe, Brazil
An offshore breakwater 543 m long located at about 2.4 km from the shore at 10 m of water depth (above chart datums) provides protection to a liquid bulk terminal (Terminal Portuarlo de...

Case Study of an Offshore Horizontal Boring
A pipeline system was needed to transport natural gas from a discovery in Mobile Block 823 to Mobil's existing system inside Mobile Bay. Sand Island, a small barrier island off Dauphin...

Environmental Effects of Beaufort Sea Causeways
Two gravel-fill causeways have been constructed into the shallow nearshore Beaufort sea on the north coast of Alaska for the development of petroleum reservoirs. These long (4-8 km) structures...

Two Basic Concepts in Offshore Engineering
Two concepts are developed which lead to an improved understanding of the characteristics of the wave forces that act on deep-water, jacket-type offshore structures. The first concept...

3D Frequency Domain Analysis of Offshore Structures
This paper reports the application of three-dimensional (3D) frequency domain computational tools to the dynamic analysis of offshore structure systems. Previous applications of 3D frequency...

Responses of Bilinear and Impacting Systems Subjected to Regular Waves
The dynamic responses of bilinear and impacting oscillators subjected to harmonic loadings are investigated. Differing from previous studies in which bifurcation diagrams were developed...

The Transport and Fate of Drilling Muds
The disposal of drilling muds from offshore oil platforms is of concern because of the potential effects of pollution from these muds. Both drilling muds and fine-grained bottom sediments...

Modeling Nearshore Currents in the Vicinity of the Endicott Causeway, Alaska
The Endicott Causeway connects two oil production islands on the southern side of Stefansson Sound, about 5 km offshore of the Sagavanirktok River delta, to the mainland of the Alaskan...

Linearisation and Offshore Fatigue Reliability
In determining the force effects due to wave action on offshore structures it is conventional to use an equivalent linearisation to convert wave velocities to forces via Morison's equation....

A Unified Simulation Approach to Structural System Reliability Analysis
To determine accurate estimates for the system reliability of large complex structures requires considerable computation; unless the problem is assessed in an efficient manner the analysis...

Offshore Pile System Reliability
The existing design methodology for offshore pile foundations is evaluated relative to the ultimate performance of the foundation system using reliability techniques and data from three...

TLP Fatigue Due to Second-Order Springing
For offhsore oil production in water depths beyond 300-350 m, the tension leg platform (TLP) has become an increasingly popular design concept. The TLP is a floating structure with excess...

A Non-Gaussian Fatigue Model for Offshore Structures
Fatigue damage accumulation in members of offshore structures can be affected by various aspects of the non-Gaussian response stress time history induced by the nonlinear/non-Gaussian...

Pile Installation and Testing at Ningbo Port, China
As part of an ambitious development program at the Port of Ningbo, the People's Republic of China constructed a 694 m (2277 ft) long offshore pier structure to provide a container berth...

Pre-Compression of Concrete Breasting Dolphins Solves Construction Problem
A roll-on/roll-off ferry terminal was built in Quincy, Massachusetts in 1989 as part of a marine transportation system to support construction of the sewage treatment facilities proposed...

Naval Homeport Facilities at Pensacola, Florida, and Mobile, Alabama
Presented herein are histories for the planning, design, and construction of the Navy's two newest homeport waterfront facilities in the Gulf of Mexico. Included are the waterfront facilities...

Model Study to Determine the Wave Forces Acting on the St. Lucie Velocity Caps

Hydrodynamic Forces and Evolution of a Nearshore Berm at South Padre Island, Texas

Wave-Current Interaction with a Large Structure
The effects of a current on the diffraction of regular waves around a three-dimensional body are examined by a time-domain method. The Froude number is assumed to be small so that the...

Design Loads for Sloshing in TLP Pontoons Tanks
Impact of fluid inside the Auger TLP ballast tanks on tank walls was investigated and changes made to the structural design in an accelerated fashion through the use of model testing....
