French harbour fleets receive an eight tug boost
The first six tugs of an eight vessel series have been deployed around the French harbour tug fleets now operated by the Boluda Group. An order was originally placed with the French shipyard Chantier Piriou of Concarneau for the construction of these vessels by Les Abeille, the harbour towage division of Group Bourbon. Les Abeille and the harbour tugs fleets were subsequently sold in 2007 to the Spanish owned Boluda Group. Construction and delivery continued and tugs already named and nearing completion were renamed and given the familiar Boluda VB prefix.
To date six vessels have been delivered
and
are in operation.
VB Octeville, VB Trouville
and
VB Yport are now part of the shiph
and
ling fleet in Le Havre; VB Camargue
and
VB Rhone were deployed to Fos, Marseille,
and
the latest delivery, VB Adroit,
is now in Dunkerque.
In each case the arrival of these virtually identical stern drive tugs, each with 70 tons bollard pull, has given the local fleets a considerable boost in power
and
efficiency. For example, in Le Havre the Boluda fleet is now made up of tugs with 65 or 70 tons bollard pull with an average age of 5 years. The remaining pair, VB Esterel
and
VB Crau, will be delivered by the end of this year
and
are also destined for Fos, Marseille.
All eight tugs are virtually identical in design
and
are equipped for fire fighting to FiFi 1 st
and
ard, oil recovery
and
pollution control. The azimuthing stern drive (ASD) design is for a vessel 30.30m in length overall, with a moulded beam of 10.40m
and
a maximum draft of 4.50m. Below the waterline the hull is fitted with a large central skeg, bilge keels
and
a transverse bow thruster. A semi-raised foredeck affords some protection in heavy weather
and
the hull is heavily fendered, with two cylindrical rubber sections fitted around the bow
and
forward quarters, one above the other. The arrangement is particularly suitable for push-pull operation. Further rectangular sections protect the sides
and
stern.
The 70 tons bollard pull
and
free running speed of 13 knots is achieved by a propulsion package comprising two ABC 8MDZC main engines coupled to Schottle SRP 1515 fully steerable propulsion units. These main engines are rated at 1,945 kW each, giving a total of about 5,285 bhp.
