Donald Langrock possesses a unique combination of engineering, research & development, project management and sea going operations experience related to diverse areas of the marine field. Don’s career started in the U.S. Coast Guard in the early 1960’s where he served as both a deck officer and later as an officer in the engineering department on major ships operating in the North Atlantic.

After completing his graduate work at MIT in 1967, he was assigned to Coast Guard’s Merchant Marine Safety Department and worked on fishing vessel stability requirements, structural fire protection for passenger ferries as well as working with the American Bureau of Shipping on load line requirements and technical committees.

In 1971, he was assigned to a project task group as engineering manager and chief inspector for the construction of two polar icebreakers with combined diesel electric and gas turbine propulsion plants. (93,000 SHP). As Chief Engineer he took the first of the vessels through shake downs and operational missions in the Arctic and Antarctic polar regions.

After retirement from the Coast Guard in 1981, he took a position with the Offshore Engineering Department of Mobil Oil where he was responsible for the development of all floating equipment for offshore oil production. In 1990, having completed all necessary prototype designs and having developed an effective and well trained engineering group, he was reassigned to Scotland, where he was responsible for R&D and deep water development projects. Working with the marine and offshore industry and many of the major universities in UK, he developed remotely operated vehicles (ROV) and associated equipment to a level of sophistication previously unseen in the field. This equipment is presently being used in many parts of the world to accomplish work previously done by divers.

Throughout his career Don has published extensively, (10 countries on four continents) and has chaired numerous technical conferences related to the marine and offshore industry. Since retiring from Mobil in 1996, he has acted as a consultant to ABS and various manufacturing and engineering firms.
