This is our primary area of expertise, having started the business in marina maintenance and construction over 20 years ago. Since then, Tas Marine has grown to deliver complex marine projects with precision and adaptability, supported by our extensive range of floating plant and specialised marine piling equipment.
With extensive experience across diverse environments, Tas Marine delivers projects ranging from marinas in urban bays and high-traffic waterfronts to some of the most exposed, remote and challenging locations. Known for our ability to adapt and excel in demanding conditions, we
have successfully navigated extreme challenges, including monsoonal weather on Christmas Island and the rugged coastal terrains of New Zealand’s South Island.
Our skilled workforce and state-of-the-art equipment enable us to overcome complex logistical and engineering obstacles, ensuring each project is delivered safely, efficiently, and to the highest quality and environmental standards.
By combining technical expertise with innovation, including pioneering hydraulic hammers and crane-based pile spinning techniques, we consistently exceed client expectations, setting benchmarks for excellence in marine and civil construction.
Our ability to operate effectively in challenging environments, coupled with our
state-of-the-art equipment and skilled workforce, sets us apart as a trusted leader in marine construction.
At Tas Marine, we have extensive experience in the construction and maintenance of pedestrian and multi-span dual lane road bridges, delivering durable and innovative solutions for critical infrastructure.

From jack-up barges and floating construction platforms to advanced piling hammers and dredging systems, our equipment enables us to operate effectively in both remote and urban locations. Leveraging our own pioneering hydraulic hammers and crane-based pile spinning techniques, we deliver innovative solutions that enhance accuracy and efficiency.
Whether working in high-tidal zones, exposed coastal terrains, or constrained urban waterways, our fleet is equipped to meet the specific needs of each project.
Combined with the expertise of our skilled team, our innovative fleet ensures every project is executed with precision, quality and environmental responsibility.
