Bureau Veritas has issued new rules for the classification of offshore service vehicles and tugs which have entered into force on 1 July, 2017. They incorporate feedback from international IMO groups focused on stability for towing, anchor handling, lifting operations and supply operations as well as cross-industry projects such as SafeTug, and are described in a new booklet (NR467-E), which is now part of the rules for the classification of steel ships.
The new rules cover classification requirements for vessels performing construction, installation, maintenance and other support activities at sea, with requirements covering towing, anchor handling, supply, fire-fighting, oil recovery, diving support, lifting, standby and rescue, accommodation, pipe laying, cable laying and semi-submersible heavy transport vessels.
Additionally, the rules address new class notations and service features for pipelay vessels, accommodation units, offshore construction vessels, offshore support vessels, wind turbine installation vessels, self-elevating units (covering the legs and elevating systems fitted on liftboats), mobile offshore units (MOUs) code compliant accommodation. Also included in this are special purpose/ number of persons on-board (SP[PoB]-capable), indicating compliance with the 2008 SPS Code for an anticipated increase of the number of persons on-board, and service notations for tugs and escort tugs (which are indications for the design values of bollard pull, steering/ braking force and speed, in combination with operating area notations for restricted operations as applicable, i.e. for harbour tugs or coastal tugs).
