Brevini is supplying gear units for applications in the offshore and marine markets that meet the requirements of the DNV Marine Approval Directive

According to the company, specifying DNV type-approved equipment enhances safety at sea and helps to prevent marine pollution; it also allows for the free movement of equipment within the European Economic Area (EEA), consisting of the EU and AFTA Member States.

DNV-type approved products will have stood up to the highest levels of testing for most applications and will have been proven to perform in the harsh environments that they will be subjected to.

Past applications include winches, cranes, pipe handling and drilling equipment, as well as a number of tidal-energy applications.

DNV-type approval covers a range of Brevini products, including standard planetary gear units up to one million nanometres; rotating case winch drive gear units up to 500KNm; slewing drive gear units up to 200KNm; and hydraulic hoisting winches up to 5 tonnes.
