Department of Ocean Engineering
Perhaps nothing in the earth's landscape captures our imagination as much as the oceans. Full of mystery, beauty, bounty and potential, they also represent the last great frontier for exploration on our planet. Since its inception, MIT's Department of Ocean Engineering has been committed to educating exceptional students who will take on this gauntlet of discovery. The field of ocean science is exciting, ever changing and challenging, as we learn more each year about the critical role of the seas in areas such as climate change, energy, transportation, global economies and nearly every aspect of our lives. In the simplest terms, ocean engineering can be defined as the development of engineering systems for use in the ocean. In our department, students examine the complex phenomena of the oceans and develop novel technologies through intensive, hands-on research. In so doing, they also gain a knowledge that fosters the wise use and preservation of these irreplaceable natural resources. We have set high goals for ourselves for the 21st century, including designing complex systems for high performance ocean vehicles, leading the information revolution in the ocean, conducting large scale experiments to better understand marine environments, and introducing chemistry and biology into the discipline of ocean engineering. Much of this work draws on earlier research in the department, and much work still lies ahead.
In collaboration with the MIT Sea Grant College Program, our department has revolutionized the design of autonomous underwater vehicles, or AUVs. Such submersibles are now unlocking secrets of the deep oceans for scientists, industry, and national defense. We look forward to a future filled with innovation and discovery, with a keen eye always on sustaining our marine environment and economy.
The mission of the department is:
- To educate and prepare students for leadership positions in industry, government and educational institutions
- To influence future directions of ocean engineering education and practice
- To develop and disseminate knowledge and technology in order to foster and enable the wise and effective use, development, and preservation of the ocean, its natural resources and its environment
The major goals of the department over the next ten years are:
- To lead the information revolution in the domain of the oceans
- To lead the application of large scale, complex system design and engineering for high performance ocean vehicles and systems
- To contribute to a better understanding of ocean dynamics through large scale experiments that complement the theoretical and numerical capabilities presently available
- To prepare ground for the next major innovation in the department, which is to introduce chemistry and biology into the discipline of ocean engineering
The department is the founding member of the National Naval Engineering Research and Education Consortium (NERC). The mission of the consortium is to develop and execute an effective, sustainable program in Naval Engineering Research and Education. NERC is a stakeholder consortium with university, government and industry representation. This is the culmination of work started by Professor Chryssostomidis and Dr. Burke in May 1999.
The Accreditation Board for Engineering and Technology reviewed the department's undergraduate program and has accredited it for an additional six years.
For the fifth year we offered Discover Ocean Engineering: A Special Introduction to MIT to the Class of 2005. This innovative program for incoming freshmen was set up in 1998 as a four day program to provide a first glimpse of what engineering is all about. It also allows the students to become familiar with some of the opportunities that the field of ocean engineering has to offer. In addition they get a jump start on becoming involved in campus life and building a close relationship between the students, our faculty and staff. As in the past, the agenda consisted of hands-on experience building a small remotely operated vehicle (ROV), testing it in the water, and providing a chance to perform some actual research experiments with an ROV in Boston Harbor. This pre-orientation program remains extremely popular among students. It has inspired Discover Mechanical Engineering, spearheaded by Discover Ocean Engineering alumnae. For the summer of 2002 plans for four Discover programs are underway: Discover Civil and Environmental, Mechanical, Nuclear, and Ocean Engineering.
In October, 2001, Professor Thomas R. Powers presented the seventh annual T. Francis Ogilvie young investigator lecture. The lecture on bacterial flagellar mechanics described the propulsion mechanics of these complex protein machines, which has many similarities with fish propulsion, an area of research in the department. Professor Powers is the James R. Rice assistant professor of solid mechanics in the Division of Engineering at Brown University.
The winner of the 2002 Wallace Prize, which is awarded to an outstanding undergraduate in the Department of Ocean Engineering, was Angus Kai McDonald. Kai was selected from a list of extremely qualified candidates and will be provided a full academic year of tuition and stipend for FY2003.
The following individuals were awarded Martin A. Abkowitz international fellowships: Dr. Alexandra Techet for her participation in an IUTAM symposium on unsteady separated flows in Toulouse, France; Justin Manley for his upcoming research at the MIT AUV Lab facility in Italy; and Dr. Tom Consi to attend and present a paper at the American Society for Engineering Education (ASEE) annual conference in Montreal, Canada in June 2002.
On May 8–9, 2002, the Department of Ocean Engineering hosted the annual Ship Design and Shipbuilding Technology symposium, part of a series of symposia and workshops established in 1986, at the MIT faculty club. This symposium is held to establish and maintain positive communication with industry, Navy laboratories and Navy programs on research and education issues relevant to the Naval Construction and Engineering curriculum. Following an introduction by the faculty supervisor, the 13A graduate students presented their theses, and design projects, which as always were very well received. RADM Paul E. Sullivan, deputy commander for integrated warfare systems, Naval sea systems command, was the May 8 banquet speaker. Over 100 people from academia, industry and the government attended this annual event.
The 22d annual Ocean Engineering reunion was held at Disney World in Florida in October 2001. The reunion is traditionally held in conjunction with the Society of Naval Architects and Marine Engineers annual meeting. The 2001 reception was hosted by Professor Chryssostomos Chryssostomidis and was well attended by alumni, faculty and guests.
Our administrative officer of many years, Sharon Trohon, was selected for the position of administrative officer at Mechanical Engineering—a well deserved move forward. Her successor, Helen L. Broderick, was hired in December 2001. Eda Daniels was recently hired as admissions coordinator in our Student Administration Office, replacing Tammy Lynch.
As the result of an extensive search for a new faculty member in the area of hydrodynamics, Dr. Alexandra Techet, a former MIT Ocean Engineering student, was hired as the department's newest junior faculty member. Alex will begin her appointment July 2002. This appointment fulfilled the top priority in the department's strategic plan.

Dr. David Burke, with the assistance of Erik Millet, support staff, and Christine Salib, an independent contractor, developed a new and upgraded version of the Ocean Engineering web site. Dr. Burke has also assumed the oversight of the new communications requirement for our undergraduates.
Professor Chryssostomidis participated in the Baratti, Italy Expedition, in August 2001 as the MIT AUV team leader. The purpose of MIT's participation in the expedition was to assist our Italian colleagues with underwater navigation.
It is with great regret that I report the death of former department head and dean of engineering Dr. Alfred Keil. A memorial service was held at the MIT chapel in February 2002 where a number of his colleagues joined with family members to recognize his many contributions to the Institute. In recognition of Alfred's significant contributions to ocean research and education, MIT has established the Alfred A. H. Keil Ocean Engineering Development Fund. The fund will perpetuate Alfred's basic principles and lifelong dedication to broad based research in ocean engineering, with special emphasis on related societal needs and concerns by providing financial support where appropriate to undergraduate and graduate students and junior faculty. A biography, Alfred Keil, Multiple Genius, has been written by Sea Grant and is available from the MIT Sea Grant college program.

13.012 Hydrodynamics for Ocean Engineers introduces the principles of fluid mechanics and applies them to practical ocean engineering problems. The fundamental properties of a fluid are investigated and the basic governing equations of fluid motion are derived in differential and integral form. Hydrostatic equations and vessel stability are discussed in the context of surface and underwater vessels. Basic flows past cylinders, spheres, flat plates and hydrofoils are used as a platform for understanding the more complex flows often found in ocean engineering and naval architecture applications.
A number of new experimental projects have been added to 13.012 to help illustrate concepts taught in class, including ship resistance and model testing, lift and drag forces on submerged bodies, and vehicle propulsion. Weekly lab sessions will be supplemented by practical problem sessions and demonstrations. Laboratory sessions are geared towards demonstrating proper data collection and analysis as well as writing clear and concise lab reports. Statistical data analysis, time series analysis, error estimation, and dimensional analysis will be discussed in the context of each lab to help students prepare for their own future research and engineering careers.
Laboratory exercises closely follow the syllabus of the subject and demonstrate physical phenomena in a hands on fashion. Interactive demonstrations help students further understand hydrodynamic stability, fluid viscosity, hydrostatic pressure as well as pressure in a moving fluid. Several laboratories are designed to demonstrate basic principles and flow features present in common ocean engineering problems. Such laboratory exercises include basic flow around circular cylinders, vortex-induced vibrations, lift and drag versus angle of attack of a hydrofoil, ship resistance and model testing, and propeller thrust and cavitation
13.019 Computational Techniques for Structural Design was offered for the second time in spring 2002. The subject introduced the loading mechanisms on ocean structures and the theory of plates and shells in the context of marine structures. Projects were completed demonstrating ability to develop computer analyses and use of advanced industry computer applications to make design evaluations. Ability to check the application tools results by hand or with simple derived computer routines was emphasized. The subject was very well received by the students.
Subject 13.49 Maneuvering and Control of Surface and Underwater Vehicles was transitioned to the internet in the fall semester of 2000. During 2001 the material posted on the internet was constantly refined and in fall 2001 was taught in its new form with great success. A dedicated, password-protected server has been set up to post lecture notes and revisions, and homework exercises and solutions. In addition, we developed the capability for students to perform time/domain simulation and linear controller design over the web using the Matlab web server. This feature is especially useful for learning about control of dynamic systems without becoming bogged down in the specific syntax of advanced controller design in Matlab.
Professors Baggeroer, Milgram and Schmidt successfully competed for funding under a new three year ONR DRI entitled Capturing Uncertainty to further develop the fundamental understanding of the relative significance of the various oceanographic and geophysical uncertainty properties to the sonar performance statistics.
Professor Chrys Chryssostomidis was the chief scientist of a ten day expedition to Argentario, Italy. An Autonomous Underwater Vehicle (AUV) was used to explore the ocean bottom for archaeological artifacts. During the Argentario expedition, the ocean bottom near Elba and Argentario was mapped using side-scan sonar. At present the massive amount of data collected during the expedition is being analyzed for images of archaeological interest. Our longterm research objective is to ground truth side-scan sonar records with visual images and start building a library of sonar targets with visual comparisons that will help future explorers identify interesting targets. Some visual images were collected by our Italian colleagues using cameras mounted on remotely operated vehicles.
Professor Nicholas Makris continues his work in a variety of fields including acoustic detection and classification of hurricanes; spectral formulation for the Doppler-shifted field scattered by an object moving in a stratified medium; reverberation and submerged target scattering in shallow water, geological clutter experiments and a search for an ocean on Europa. He has also led a very successful ONR sponsored expedition, which confirmed that buried river channels are the primary cause of geo-clutter.
Professor John Leonard continued with the development of decoupled stochastic mapping (DSM) and initiated a new project under funding from Draper Labs for extension of the approach to multiple robot navigation. The goal is for several vehicles to cooperatively perform concurrent mapping and localization (CML). In addition, he is working on real time implementation of CML onboard an Autonomous Underwater Vehicle (AUV).
Professor Nicholas Patrikalakis continued with his Solid Freeform Fabrication (SFF) research, a major NSF and ONR project which has as its objective the development of a generalized solid modeling method for SFF, providing support for design, representation, visualization, and manufacture of solids with local composition control (LCC), which is not possible in today's CAD/CAM systems. In the CAD area, Professor Patrikalakis works on two additional NSF-funded projects. The first relates to the intrinsic watermarking of solid bounded by sculptured surfaces, thereby providing a method for object identification and ownership protection in an electronic environment. The second project relates to robust intersection algorithms and rectification of CAD models to allow their correct interpretation during translation from one CAD system to another. In addition, Professor Patrikalakis based on early work on his NOAA-funded project, Poseidon: A Coastal Zone Management System over the World Wide Web, initiated research on a new major NSF/ITR project, also under the name Poseidon, for rapid real time interdisciplinary ocean forecasting in a distributed computing environment focusing on adaptive sampling and adaptive modeling aspects of the problem.
Professor Henrik Schmidt's research on the multi-static active acoustics project, is to develop fundamental understanding of the acoustic environment of the seabed, and to develop new numerical models of the 3D scattering by seabed objects, such as mines and hazardous waste containers, on and below the seabed in shallow water. Closely tied to the multi-static acoustics effort is the Generic Ocean Array Technology Sonars (GOATS), a new system concept for acoustic observations in the ocean environment, replacing the traditional hardwired hydrophone arrays. This is done by a virtual array of small underwater vehicles each equipped with a small aperture array, and linked together by high-bandwidth acoustic or optical links. GOATS is envisioned as the enabling technology which with the new 3D modeling capabilities can be synergized into an entirely new sonar concept for mine counter measures and undersea warfare in shallow water. A very successful GOATS 2002 was just completed this spring.
Professor Michael Triantafyllou, among several other projects, has completed the first period of research funded by Sea Grant and partially by NAVSEA, on the development of a biomimetic underwater vehicle, capable of swimming in strong currents and large waves, thanks to fish-like flapping fins. A fin-based actuator has been designed and constructed that produces large forces rapidly. This is the first of several such fins that are needed for the vehicle, which will have many uses for oceanographic, reconnaissance, and archeological work underwater.
Professor Tomasz Wierzbicki continues to lead the highly successful Impact and Crashworthiness Laboratory in the department. Professor Wierzbicki's laboratory in addition to the highly successful research in automobiles has embarked in a new area of research dealing with structural failure due to extreme loads. His most recent research in this area deals with development of blast resistant adaptive sandwich structures.
