The yachting and commercial marine industries turn to Dan Hanes and Sea3 Systems for electric vessel technology.

Dan Hanes is a registered professional engineer in Florida #42940 possessing an extensive background in technical management and in instrumentation, test, inspection and survey programs.

Dan managed hardware and software development of electrical and electromechanical systems for offshore energy, undersea, commercial and military applications. He has written, won and executed numerous successful federal grants, managed complex interdisciplinary projects, and designed, implemented, tested, documented and certified complex systems to stringent military and commercial requirements.

As president of Sea3 Systems LLC, Dan leads a team providing general engineering management as well as electrical, software and mechanical design engineering for vessels and underwater platforms and subsequent surveys, modification plans and preparation of detailed reports.

Other key projects include survey, documentation and modifications to Kreuz Subsea  for Brunei Shell Petroleum, Singapore. This is a 91 meter diving support vessel which we achieved compliance with OGP 468 guidelines.

Additionally, Dan provided design, documentation, safety analysis and verification of modifications to the electrical power distribution, communications and instrumentation systems for a 360 meter saturation diving system to meet DnV Class requirements for Global Diving and Salvage, Lake Charles, LA.

Miami-based Royal Caribbean Cruise Line contracted Dan for detailed design of modifications to cruise ships supporting the addition of exhaust gas scrubber systems. The projects included electrical detailed design, PLC based control design, watertight bulkhead and door refits and HVAC system design.

The University of Miami, Rosenstiel School of Marine and Atmospheric Sciences in Miami, FL contracted Hanes for basic design for an extensive refit of the electrical, control and dynamic positioning (DP) systems of a research vessel.

The University of North Carolina Wilmington, NC tasked Dan to develop and fabricate an acoustically retrievable deep ocean benthic lander; subsequently, Dan managed the design and manufacturing of four autonomous benthic landers for long duration deep ocean research.

Prior to forming Sea3 Systems, Dan formed and led Marisys, Inc. providing naval architecture, electrical and software engineering as well as manufacturing.

For USSOCOM and primary contractor Northrop Grumman, Dan developed and manufactured the life support control system for the U.S. Navy Advanced SEAL Delivery System (ASDS) multi-compartment lockout submarine, including gas analyzers and oxygen controllers as well as a central computer system and high criticality certified software, for operation in a hyperbaric environment.

For USSOCOM and MacDill AFB, Dan designed and manufactured high brightness, high resolution, rugged navigation system displays for high performance combatant craft, designing to MIL-STD-461, MIL-STD-810.

Earlier in his career, Dan was technical manager for Motorola, Inc., managing an interdisciplinary team of software, electrical, mechanical and industrial engineers to develop advanced robotic manufacturing systems and associated software QA and revision control.

Dan was also senior control system engineer for PPG Chemicals, where he designed process control systems for petro-chemical plants including software development and safety certification for PLCs controlling critical processes. He developed computer simulations of process kinematics and associated control systems and also conducted FTA and FMECA safety analyses.

At Schlumberger Offshore Services, Dan was a general field engineer managing field teams for oil well survey and intervention services on terrestrial and offshore rigs. He conducted electromagnetic, acoustical and nuclear surveys of offshore oil and gas wells and developed QA procedures for well surveys and performed subsequent petrochemical analysis for client presentations.

Dan received his B.S. in electrical and mechanical engineering from Duke University, completing graduate work at Florida Atlantic University in

ocean engineering, software engineering and robotics. He is chairman for the southeast section of the Society of Naval Architects and Marine Engineers (SNAME). In 2017, Hanes received his FCC general radiotelephone license with radar endorsement.
