GENERAL
BACKGROUND: For over four decades Mister Trenhaile consistently demonstrates an ability to apply his broad work experience and education in naval architecture, marine engineering, safety and contracting. He often serves as an admiralty, maritime, boating or marine engineering expert witness. Besides testimony, he provides engineering reports, calculations (failure analysis, stability, safe design, etc.) and drawings for litigation. His work also involves forensic marine surveying which includes testimony analysis, safety and regulatory issues, site photography, incident reconstruction, and marine human factors engineering (or ergonomics). He is also involved in the design, renovation and certification of commercial, public and private vessels. He is interested and capable of working on all types of vessels. His work reflects a basic philosophy that vessels are to be strong, seaworthy, functional, safe, economical and aesthetic.

PERTINENT
EXPERIENCE: Registered Professional Engineer
Naval Architect and Marine Engineer
HAWAII MARINE CO., Kaneohe, HI. 6/81 - to present
In this position Mr. Trenhaile demonstrates a wide variety of experience. Responsibilities entail expert witness services (including forensic marine surveying), client contact, design, calculations, engineering reports, letters, specifications compliance, vessel optimizations, project management, vessel stability testing, computer aided drafting and design.
His expert witness work includes testimony, engineering reports, calculations (failure analysis, stability, safe design, etc.), scaled drawings, testimony analysis, safety and regulatory issues, research, photography, incident reconstruction and marine human factors engineering (or ergonomics). He serves as an expert in admiralty, maritime, boating, naval architecture, marine engineering and yacht design.
As a principal engineer for this firm Mister Trenhaile is often responsible for "design synthesis." This is where he is required to come up with (or derive) special engineering solutions where no previous procedure is known to exist.
Some of the projects completed by Mr. Trenhaile are as follows: Worked as part of a team for obtaining U. S. Navy certification of a 517' steel floating dry-dock. He has also conducted or participated in several vessel stability tests involving tugs, workboats, fishing boats, passenger vessels and a drydock.
He was also responsible for designing the following vessels; 72' x 24' Steel Passenger Riverboat, 79' Commercial Fishing Vessel, 60' x 30' Steel Passenger Transfer Catamaran Float, 41' Steel Commercial Fishing Vessel, 27' Fiberglass Tour Diving Boat, 13’ clear kayak and a 12'x 8' Wood Utility Catamaran. Numerous structural and stability calculations, computer models, engineering reports and computer drawings were done on other vessels as well.
Much of his work requires compliance to U. S. Coast Guard and American Bureau of Shipping rules and regulations.
Naval Architect
SINCLAIR AND ASSOCIATES,
Here Mr. Trenhaile completed a comprehensive stability analysis for a dredge barge while in operation and at sea, in accordance with the United States Coast Guard criteria for safe operation and transit. He also did the loading analysis and complete weights and moments calculation for the barge and also the crane plus its variable load.
He has worked on resistance and propulsion calculations for a 17' planing vessel, and has also assisted in the testing of this prototype vessel for T. L. Sinclair.
Mr. Trenhaile has also worked on the determination of critical loading orientation and a in depth theoretical structural analysis, including composite section analysis of wood, steel and asphalt, as a result of container cargo crane operation for jack-up type barges.

PACIFIC MARINE, a Unitek Company,
This type of work involved numerous large and small scale projects for the U.S. Navy, U.S. Coast Guard, Military Sealift Command, shipping companies, passenger liner companies and other maritime related companies, organizations and individuals; the scope of experience he obtained here is considerable, ranging from repair and fabrication to the complete redesign and overhaul of large vessels, including hull, superstructure, propulsion equipment, cargo service equipment, crew and passenger accommodations, piping, refrigeration, ventilation, insulation, heating, electrical, electronic and other ship equipment.
Valuable experience was also obtained in dealing with administrators, managers, supervisors, engineers, technicians, subcontractors, salesmen, government representatives, work force and office staff. Much of his time was spent with shop production supervisors, subcontractor supervisors, ship personnel and material suppliers in the procurement and distribution of information, and in the clarification of work scope, contract documents and drawings. A considerable amount of his time was utilized in estimating labor, materials, ship checking and coordination bids with subcontractors; he also made labor distribution breakdowns (by trade) and item scheduling (milestone charts) as part of the bidding process. Mr. Trenhaile was primarily responsible for some of the firms successful bids which ranged in value from approximately $500 to $2,000,000; he also assisted in the planning and monitoring the various phases of production.
As a manager he was responsible for writing test and inspection plans for US Navy contract items and for the supervision of the quality assurance inspectors, also responsible in part for the program implementation and the continuity of the system.
When required he has headed small marine engineering design teams to do technical work and drawings; this included the practical application of thermodynamics, hydrodynamics, hydrostatics, chemistry, and solid mechanics. These drawings often consisted of arrangements, bill of materials, installation details, operational diagrams and notes. His duties also included teaching engineers and technicians for other managerial and administrative positions.
