It’s thanks to our invaluable experience and expertise that we’re valued for our robust, fuel-efficient vessel designs and for our reputation as a design leader.

We’re continually increasing the range of available sizes of our proven CTV designs and we currently have over 40, ranging from 18 metres to over 30 metres. These new, longer vessels meet the industry’s growing demand for capacity and prolonged offshore operations. Advanced hullforms such as our XSS (eXtreme Semi-Swath), provide that capacity along with improved seakeeping and operability. Our larger offshore fast crew boats for the Oil and Gas market also deliver class-leading fuel efficiency.

The BMT designs offer: superior seakeeping for improved comfort; up to 20% saving in fuel consumption for equivalent vessel payloads; novel hull forms for improved docking performance and minimum weather downtime and; high payload capacity.

Beyond the main hull design, we have invested in several research and development programs to improve operability through Turbine Access Systems and Active Fender Systems. These significantly help reduce the potential for impact damage to either the vessel or turbine structure and enhance the safety of the technician transfer.


We have an ever-expanding range of proven vessel designs in our portfolio, including vessels ranging from 9m to 220m in length and speeds of up to 70 knots.
