Vessel Lifecycle Services

At Heddle Shipyards, we believe the best service is provided by working with clients for the duration of their vessel’s lifecycle.

Our Vessel Lifecycle Services include new build construction, maintenance, conversions, overhauls, emergency repairs and vessel recycling.

Heddle Shipyards is well suited to manage your vessel from construction to recycling. Whether you are planning a new build project, vessel life extension or routine maintenance, we will work with you to build a comprehensive long-term maintenance plan that addresses your specific needs and maximizes value. 

Vessel Construction

Over the past 30 years, Heddle Shipyards has methodically built up a robust marine construction reputation in Canada. A wide variety of projects have floated off our dry docks in Hamilton Harbour: from workboats to barges, cable ferries and sub-sea cable-laying equipment. 

As our business has grown, so has our production capacity. With the acquisition of the Port Weller Dry Docks in 2017, Heddle Shipyards is even better situated to take on complex construction projects.   

Repairs, Maintenance, Overhauls and Conversions

Repairs, maintenance and conversion projects have been the foundation of our business since our inception. From emergency repairs to special survey dry dockings and vessel life extension projects, Heddle Shipyards has experience from stem to stern.

Steel replacement, re-powering, structural remodeling and accommodation retrofits are just a few of the areas in which our experienced workforce excels. Large or small, alongside or on the blocks, Heddle Shipyards is ready to take on your most ambitious project.
