John Polglaze

The principal of PGM Environment is John Polglaze.

John is recognised internationally for his work on the environmental assessment and management of ship designs and operations, port developments and operations and related matters such as marine anthropogenic noise. He has spoken on this latter subject, by invitation, in Australia, the United States, Italy, Denmark, Ireland, Latvia and the Netherlands, and is a regular invitee to NATO seminars on this subject.

Areas in which John Polglaze has particular expertise also include ship disposal and sea dumping, ship waste management, and vessel biofouling management. He was project manager for the biofouling survey for a major Australian maritime organisation, in a two-year program involving over 40 drydock and in-water dive inspections of multiple types of ships, boats and specialist vessels, ranging from 250t to 42,000t displacement. This survey led to work to develop biofouling management policy and procedures at the national and international levels. This work underpins the deep understanding that PGM Environment has regarding biofouling patterns on ships and inherent ship biofouling vulnerabilities. John chaired the biofouling session of the IMO sponsored 1st International Ballast Water Risk Assessment Workshop.

John founded PGM Environment after 10 years with a major multi-national engineering and environmental services company. He has over 35 years’ of maritime experience, having initially developed his maritime knowledge serving in the Royal Australian Navy for 19 years in submarines and surface ships. He is a qualified Submariner.

John also has experience working as a commercial diver.
