Dry Dock Training



The Dry Dock Training Course provides in-depth technical guidance on the process of dry-docking ships and vessels. The course begins with the basic principles and safety concerns, then progresses through all phases of drydocking; preparation and planning, drydocking, lay period, and undocking. The course ends with a discussion of past accidents. With over 150 years of dry dock experience, DM Consulting brings clarity and organization to an otherwise complex set of drydocking principles. 
DM Consulting is the world leader in dry dock training. Past participants included representatives of shipyards, engineering companies, consulting firms, ship owners, and government agencies from six continents. See for details on the 4-day training course including a list of past attendees and testimonials. DM Consulting's Dry Dock Training Course has accreditation with both The Society of Naval Architects & Marine Engineers (SNAME) and The Royal Institution of Naval Architects (RINA). Both experienced and inexperienced dry dock  personnel have benefited from attending the training. Over 75% of all course attendees rate the course as "excellent".
