The Academic Program

Ocean and Resources Engineering is the application of ocean science and engineering design to the challenging conditions found in the ocean environment and to the synthesis of novel products from marine systems. Waves and currents, turbulence, dynamic loads, mobile sediment, high pressure and temperature variations, ocean acoustics, marine instrumentation, as well as chemical and biological processes, are among the considerations that set ocean and resources engineering apart from conventional land-based engineering.

Educational and research emphasis is placed on coastal engineering, offshore engineering, and ocean resources engineering. Coastal engineering deals with coastal and harbor problems, sediment transport, nearshore environmental engineering, and coastal flood hazards due to storm surge and tsunamis. Offshore engineering is concerned with structures and systems used in the deeper parts of the ocean, including the continental shelf. It also includes hydrodynamics of fluid-body interaction, seakeeping and dynamic responses of marine vehicles and platforms, and hydroelasticity of very large floating structures. Ocean resources engineering is concerned with the engineering systems to develop the energy, minerals and living resources of the oceans, the use of the ocean for waste disposal, and the environmental and economic aspects of these activities. The MS program in ocean and resources engineering is accredited by the Accreditation Board for Engineering and Technology (ABET), which provides accreditation services to the first degree offered by engineering programs.

The educational and research programs in the department have a good balance between numerical and laboratory modeling as well as field observation. Computing facilities include 5 Linux systems and a network of Pentium-based PCs. The cluster Kiwi comprises a 44 TB RAID and 22 processing nodes each containing 2 Intel Quad Core X5460 processes with 24 GB RAM. The department also maintains a number of software packages that are available to the students for course work and research.

The department's Environmental Fluid Dynamics Laboratory (EFDL) focuses on the study of coastal marine processes including turbulent dispersal of pollutants and nutrients, wave dynamics, and sediment transport as well as fundamental fluid processes such as vortex breakdown and boundary layer turbulence. In addition, the laboratory is home to the Environmental Fluid Dynamics Education Laboratory, which serves as a center for teaching of fluids phenomena. Laboratory instrumentation includes acoustic Doppler velocimeters (ADVs) which obtain high frequency, single point, 3-component velocity measurements, and a laser-based digital particle imaging velocimetry (DPIV) system that obtains two-dimensional fluid velocity via laser imaging techniques. A pulsed Nd:YAG laser and UV light system with digital still and video cameras are used for flow visualization and measurement. The EFDL houses multiple experiment tanks, which are used for both research and teaching demonstrations. These include a 10-meter long, 30 x 10 cm wave channel, and a small rotating table. The tanks allow demonstration of a range of fluid flow phenomena including wave breaking, downslope currents, internal waves in stratified fluids along with rotational effects such as spin-up, Ekman flow and geostrophy.

The department maintains facilities at Kewalo Basin and Snug Harbor in Honolulu for fieldwork and in-ocean experiments. The department operates the Kilo Nalu Observatory offshore of Kakaako, which provides cabled power and Ethernet for in-ocean experimentation at 10 and 20m depths. Kilo Nalu provides comprehensive, real-time observations of ocean currents, waves and water properties, and hosts multiple ongoing research projects focused on coastal ocean processes and instrument development. Field observational equipment includes a REMUS autonomous underwater vehicle (AUV), an LBV 150 remotely operated vehicle (ROV), an array of wave gauges, acoustic current profilers, and current meters. In addition, the department has access to a 25-ft twin-outboard motorboat, two ocean-going vessels operated by SOEST, two 2000m depth submersibles operated by the Hawai'i Undersea Research Lab and a new 6000m ROV which services the ALOHA Cable Observatory (ACO). ACO is the deepest operating node (power and internet) on the planet. ACO provides real time acoustic monitoring and communication.

In ocean acoustics, gliders are being used as gateways communicating between underwater mobile and fixed nodes and pilots on shore. Hydrophones on gliders monitor for ambient sound including marine mammals, wind and rain, and shipping. Research on detection, classification, and tracking of marine mammals and divers is underway. Tomographic remote sensing work is being developed for use on small scales in local waters as well as on regional and basin scales.

The graduate program in ocean and resources engineering channels the students' previous engineering or scientific experience to ocean-related careers. Approximately 38% of the students graduating between Fall 2007-Fall 2013 found immediate employment in private industry including oil companies, engineering firms, environmental service firms and construction companies in the U.S. About 13% joined or continued their employment with federal or state agencies. 28% continued studies either by pursuing a higher degree or a post-doctoral position. 6% were employed by UH in engineering research positions. 4% returned to their countries of origin pursuing engineering. 2% received a tenure-track faculty position. 9% decided to pursue non-engineering positions. 62% of the graduates stayed in Hawai'i.

Graduate Study

Educational Objectives

The Department of Ocean and Resources Engineering offers a graduate program leading to the Master of Science (MS) and Doctor of Philosophy (PhD) degrees. The goal of the program is to prepare students for the engineering profession and to conduct research in the support of the educational program. The objectives of the program at the MS level are to produce graduates who, during the first few years following graduation:

  1. Are effective and creative engineers applying knowledge of mathematics and science to the solution of practical engineering problems;
  2. Have general understanding of and ability to work in the ocean and resources engineering disciplines;
  3. Are proficient in one or more of the ocean and resources engineering disciplines;
  4. Are aware of professional, managerial, legal, ethical, and other non-technical issues commonly encountered in engineering practice;
  5. Can communicate and work effectively with peers, clients, and the general public in promoting new ideas, products, or designs; and
  6. Can adapt to the changing needs and technology of the ocean and resources industry.
The program at the PhD level shares these objectives with the additional emphasis to produce graduates who:
  1. Are productive researchers conducting original research and developing new technology in ocean and resources engineering; and
  2. Have the experience to publish in refereed journals.

This additional emphasis prepares the PhD graduate to pursue research careers in the industry or academia.

Admission Requirements

Students are admitted for graduate study on the basis of their scholastic records. Degree candidates for the MS program usually have a bachelor's degree in an engineering discip­line that provides an adequate background in mathematics, physics, chemistry, and mechanics. Students seeking admission to the PhD program should have an MS in engineering or equivalent qualification. However, exceptionally well qualified students with a BS in engineering, who do not have a master's degree, may petition to be admitted to the PhD program directly. Students with mathematics, physics, or other science backgrounds may be admitted to the program, but are required to take specific undergraduate engineering courses to satisfy the pre-program requirements.

Deadlines to submit applications for admission to the graduate programs are January 15 for fall semester admission and August 15 for spring semester admission. The ORE application checklist (available on the ORE website) lists all the forms and supporting documents that need to be submitted; some forms and documents are submitted to the Graduate Division while others are submitted directly to the ORE department.

Detailed Graduate Division requirements and forms are available at manoa.hawaii.edu/graduate/content/prospective-students. Official scores in the GRE General Test are required from all applicants. Official TOEFL scores are required from all non-native English speaking students.

Forms required by the department can be downloaded from the ORE admissions webpage at www.ore.hawaii.edu/OE/ore_admission.htm:

  • supplemental information form
  • statement of objectives
  • letter of recommendation form
  • graduate assistantship application
  • Once an application is complete, the Graduate Division performs an initial screening to assure that admission requirements are satisfied. The Admission Committee and department chair then evaluate the application and determine the admissibility of the applicant to the ORE department.

    Master’s Degree

    The MS degree in ocean and resources engineering may be earned under either Plan A (thesis) or Plan B (non-thesis). The program requires a minimum of 30 credit hours. At least 24 credit hours must be earned in advanced courses numbered 600 or above. Up to 2 credit hours of directed reading and 6 transferred credits can be counted toward the MS requirements. Students are required to take the general examination during the first semester of their full-time enrollment to test their knowledge in mathematics, science, and basic engineering. Passing the examination advances the student to master's candidacy.

    Students generally devote their first semester to the basic disciplines in ocean and resources engineering and then specialize in coastal, ocean resources, or offshore engineering by taking the required courses in the area. The core courses ORE 411, 601, 603, 607, and 609 cover the basic disciplines that include hydrostatics, hydrodynamics, oceanography, water waves, underwater acoustics, and field and laboratory work. One credit of seminars, ORE 792, is also included in the core requirements. The required courses are ORE 661, 664, and 783B in coastal engineering; ORE 612, 630, and 783C in offshore engineering; and ORE 677, 678, and 783D in ocean resources engineering. The ORE 783 Capstone Design Project is team-taught by faculty members and practicing professional engineers to prepare students for the engineering profession. The core and required courses amount to 25 credit hours and the remaining credits are to be chosen to form a coherent plan of study.

    Students complete their study with a Plan A thesis or a Plan B independent project. The thesis option is research oriented and students receive 6 academic credits for the work. The project option focuses on engineering application or design and carries 3 academic credits. Both require a proposal outlining the subject area, objectives, proposed methodology, sources of data, and anticipated results that must be approved by a committee of at least three graduate faculty members. The work results in a thesis or a report that demonstrates both mastery of the subject matter and a high level of communication skills. Students must present and defend the work at a final examination, which provides the faculty an opportunity to test the students' understanding and ability to integrate their work at the MS level.

    The general and final examination may be repeated once. The general examination must be taken earlier than the semester in which the final examination is taken.

    PhD Degree

    Students pursuing the PhD degree are required to achieve a broad understanding of the principal areas of ocean and resources engineering, as well as a thorough understanding of a specific area. Students must, at a minimum, possess the knowledge covered by the core courses of the MS degree in ocean and resources engineering.

    All intended candidates for the PhD degree will take a written qualifying examination before or during the third semester of full-time enrollment. In addition to covering the basic undergraduate fundamentals, the examination tests the students' understanding of the course work at the MS level. After passing the examination and being advanced to candidacy, students must take a comprehensive examination, which tests their ability to carry out original research and preparation for the selected dissertation topic.

    The dissertation topic must be approved by a committee consisting of a minimum of five graduate faculty members with at least one outside member. Students are encouraged to publish the research work in refereed journals in order to obtain feedback from the research community and to develop a publication track record prior to graduation. They must present and defend the novelty of the dissertation at a final examination.

    The qualifying and comprehensive examinations may each be repeated only once. The final examination may not be repeated, except with approval of the graduate faculty involved and the dean of the Graduate Division.

    Advising

    Upon admission, the department chair meets with each incoming student at a preliminary conference to discuss the program requirements and determine any pre-program deficiencies.

    The graduate chair serves as the advisor to students without an undergraduate engineering degree until they satisfy the pre-program requirements. Once pre-program requirements are met, the department chair appoints an academic advisor from the pool of ORE departmental faculty. The academic advisor is tasked with helping students navigate through the requirements of the program and ensuring that the guidelines are met. At the start of the research phase, students select a research advisor to guide their research and serve as their committee chair.
