Dry Dock Training Course
The Dry Dock Training Course provides in-depth technical guidance on the process of drydocking ships, vessels and yachts. The course begins with the basic principles and safety concerns, and 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, the Consultants bring clarity and organization to an otherwise complex set of drydocking principles.
Description
The Consultants delivering this course are the world leaders in dry dock training. Past participants included representatives of shipyards, engineering companies, consulting firms, ship owners, and government agencies from six continents. This 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".
