High Quality Content by WIKIPEDIA articles! Ocean Engineering is an ambiguously defined discipline, but may refer to Oceanographic Engineering a term describing marine electronics engineering applied to supporting the work of oceanographers; or, may refer to offshore engineering, or maritime engineering, which is the branch of engineering allied to civil engineering, and concerned with the technical aspects of fixed and floating offshore marine structures and systems related to harnessing ocean resources. These include offshore oil and gas and the rapidly expanding area of ocean renewable energy, as well as other ocean resource activities such as sub-sea mining and aquaculture. As with all engineering disciplines ocean engineering should be concerned with the design and operation of systems ? in the ocean; and should not be confused with oceanography ? the scientific study of oceanic systems; nor marine electronics engineering (oceanographic engineering), which is concerned with the design and operation of remote sensing systems. ...

Product Description
This is a NAVAL FACILITIES ENGINEERING SERVICE CENTER PORT HUENEME CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A075324. The abstract provided by the Pentagon follows: Two precision asset location (PAL) systems were tested on the SS curtiss in Port Hueneme, California. The two systems were a commercial-off-the- shelf direct sequence spread spectrum (DSSS) system from WhereNet, Inc., and a prototype ultra-wideband (UWB) system from Multi-Spectral Solutions, Inc. (MSSI) . The objective was to evaluate the two technologies for operation in high multipath shipboard environments. Testing was performed in open cargo spaces (worst-case multipath) and partially loaded cargo spaces (blockage). A reference laser surveying system was installed for comparison and accuracy tests were conducted over a cargo space. Both systems operated in the open-space shipboard environment and to each vendor's specified accuracy. Each system's accuracy decreased during blockage experiments. The University of Southern California's UltRa Lab characterized the SS Curtiss shipboard environment and found it had delay spreads on the order of 3 microsec, far exceeding the 10 to 300 ns delay spreads of office and industrial environments. Multipath nulls were also measured, with some as deep as 30 to 40 dB. ... Read more

Product Description
Ocean Engineering is simply defined as the application of engineering principles to the ocean environment. Ocean engineering is a very challenging field addressing the use of this vast ocean frontier while striving to protect the same ocean environment and marine life. The book Elements of Ocean Engineering is intended for use as a first course for ocean engineering and naval architecture students and as an overview for practitioners in ocean engineering and related fields. The topics covered include ocean wave mechanics, offshore and coastal applications, floating systems, underwater systems, ocean engineering materials, instrumentation, underwater acoustics, dredging, laboratory modeling, environment and safety, and ocean engineering design. Robert Randall is Professor of Ocean Engineering in the Civil Engineering Department of Texas A&M University. ... Read more

Product Description
This new revised volume on Strength of Ships and Ocean Structures addresses several topics of ship strength in greater depth than in the previous edition of PNA, bringing much of the material up to date and introducing some new subjects. There is extensive coverage of the latest developments in dynamic sea load predictions, including nonlinear load effects, slamming and impact plus new sections on the mechanics of collisions and grounding. The incorporation of the various loadings in structural design and analysis is covered including long term extreme and cumulative fatigue effects. There is a more extensive treatment of strength analysis using finite element methods than was included in the previous edition. Ultimate strength evaluation of the hull girder and components is covered and there is a section on structural safety assessment applying reliability concepts including fatigue effects. Particular attention is given to problems encountered in ships of special type and size that have been developed in recent years, many of which, by reason of size, configuration or lack of a history of design experience, require a design approach based on first principles. Modern developments in classification society strength standards and modern rule developments are covered including Common Structural Rules for tankers and bulk carriers. The concluding sections discuss materials other than steel, including composites and aluminum, and vessels of unusual geometry and performance such as multihulls, hydrofoils, and SWATH craft. ...
