That experience and expertise has won us a reputation as the design leader in the market, valued for our robust, fuel-efficient vessel designs with excellent seakeeping.

We continue to increase the size range of our proven CTV designs. Today, we have designs for over 40 vessels ranging from 18 to 30+m designs. These new, longer vessels meet the growing industry demand for both capacity and prolonged offshore operations. Advanced hullforms such as our XSS (eXtreme Semi-Swath) provide that capacity 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.


BMT has an ever expanding range of proven vessel designs with the portfolio including vessels ranging in size from 9m to 220m in length and speeds up to 70 knots.
