Staff

Jose Andres, Ph.D., P.E.
President

Dr. Andres is Makai’s President and CEO. He is responsible for all aspects of Makai’s diverse portfolio of business and leads a team of technical program managers in all areas of Makai’s engineering research and design. After assuming leadership of the company from Dr. Van Ryzin in 2006, Dr. Andres led the rapid growth of the company and created the newest division of the company – the scientific visualization software division, to which he continues to contribute to as a technical lead.

Dr. Andres’ extensive technical expertise includes his service as the Senior Ocean Engineer and Division Head of Makai’s Cable Control Software divison. Over the last 25 years under Dr. Andres’ direction the cable control software grew from an R&D project into the #1 worldwide standard for telecom subsea cable lays, and has been used for the installation of over 200,000 km of subsea cable. The software has also been utilized in defense applications such as the installation of U.S. Navy and Australian Navy acoustic ranges and in towed arrays from surface and underwater platforms. The functionality and accuracy of Makai’s cable control software is unrivaled in the industry and we look forward to expanding its application to new markets.

Joe Van Ryzin, Ph.D., P.E.
Vice President of Engineering

Dr. Van Ryzin is founder and Vice President of Makai Ocean Engineering. He has been a Senior Ocean Engineer in every major program at Makai since founding the company in 1973, and serves as the Division Head for Makai’s ocean thermal energy conversion (OTEC) division. His work has included leading-edge research in the areas of ocean renewable energy, especially seawater air conditioning (SWAC) and OTEC; deep water cable laying software; marine vehicle and buoy system design; and diving and undersea habitat system design.

Dr. Van Ryzin is an internationally respected expert on OTEC, and his experience with the technology dates back to the world’s first net-power producing OTEC plant – mini-OTEC – in 1979. Since that time, Dr. Van Ryzin has led unique R&D projects for a variety of government and commercial clients worldwide. This work includes designs for commercial 100MW and pilot OTEC plants, research and development of mooring systems, pipelines, heat exchangers, and comprehensive OTEC technical and economic modeling software.

Dale Jensen, P.E.
Division Head: Seawater Air Conditioning (SWAC) Systems

Mr. Jensen is the technical leader of Makai’s SWAC division. Under Mr. Jensen’s direction, Makai has become the de facto world leader in SWAC system engineering and design, with more deep water SWAC pipeline designs installed and operating than any other firm. Most recently, Mr. Jensen led the design and installation management planning of a 1.6 meter (63″) deep ocean cold water intake pipeline and 1.4 meter (54″) discharge pipeline for the Honolulu Seawater Air Conditioning project which is scheduled for installation in 2014.

Other recent projects Makai has led under Mr. Jensen’s direction include:
Deep ocean water systems at Natural Energy Laboratory of Hawaii Authority (NELHA). This includes the repair of a 40″ deep water intake pipeline; the design and construction management of the 55″ deep water and near shore intake pipelines, onshore pipelines, pump station and mechanical equipment; The Enwave Toronto deep lake water cooling project which involved the design of 3 each 63″ diameter intake pipelines extending 18,000 feet into Lake Ontario; The Cornell Lake Source Cooling Project which uses a “district energy” model to provide 20,000 tons of centralized cooling for the university. The intake pipeline is two miles long with an intake at 250′ depth. The pipeline provides 32,000 gpm of cold water and has a 75-year lifetime; The Kimberly-Clark’ and the City of Everett, Washington outfall for which Makai served as lead design engineer on the deep water 63″ diameter high density polyethylene (HDPE) outfall pipe, a 2700- long pipeline with a 1600- diffuser section.

David Lipp, M.S.
Senior Ocean Engineer: Cable Control Software Systems

Mr. Lipp has 30 years of experience related to the design, operation and testing of ocean related software and hardware systems. He served as project manager for the U.S. government funded development of a submarine cable planning software. The resulting software, MakaiPlan, has become the standard for submarine cable planning worldwide. Mr. Lipp also served as a program manager in Makai’s OTEC division, developing data acquisition and control software for an OTEC demonstration plant, software for the thermodynamic modeling and analysis of OTEC systems, and a technical OTEC software model to estimate site specific funding requirements of OTEC plant construction and operating expenses which was used in U.S. military feasibility studies comparing the economic benefits of OTEC plants constructed at different locations.

Before joining Makai, Mr. Lipp worked as a senior design engineer and was the principal investigator for the Naval Ocean Systems Center in Hawaii in charge of a multi-million dollar, multi-year contract developing and testing submersible vehicles, including the Advanced Tethered Vehicle (ATV). He was the technical lead in the design of the ATV overboarding A-Frame and ram tensioner system, coordinated and supervised the fabrication, assembly, integration, and testing of subsystem components as well as assisted in the development of a set of underwater hydraulic tools for use by the ATV.

Pat Grandelli, M.S., P.E.
Senior Ocean Engineer: Ocean Thermal Energy Conversion (OTEC) Systems

Mr. Grandelli is a lead engineer in Makai’s OTEC division as well as Makai’s SWAC division. Mr. Grandelli’s experience with OTEC includes playing a key role in the design of an OTEC technical and economic model, leading an Office of Naval Research project to consider the use of Ocean Thermal Energy Conversion plants, serving as a lead operator and data analyst for the 50 kilowatt OTEC heat exchanger test and 1MW Conceptual Design project performed for the Center of Excellence in Research for the Ocean Sciences (CEROS).

In Makai’s SWAC divison, he worked on design and/or construction observation for the 400mm diameter 900-meter-deep seawater intake pipeline for the InterContinental Resort & Spa in French Polynesia, the 48″ Waikiki Beachwalk sewer force main, the 63″ Los Angeles Stone Canyon Water Quality Improvement Project, the 55″ NELHA pipeline in Hawaii, Toronto’s three 63″ Deep Lake Water Cooling pipelines, and Cornell University’s 63″ Lake Source Cooling Pipeline. He has helped to push the boundaries of deep cold water pipeline limits by designing, building and operating a device to test pipelines subject to cyclic suction loading, as well as a unique coldwater clathrate heat exchanger.
