Robert Allan Ltd. Designs TundRA 3200 Icebreaking Tugboats for Alfons Håkans

March 11, 2019

Robert Allan Ltd. is very pleased to announce an important milestone having been selected the designer of new icebreaking tugs for Alfons Håkans, a major tugboat owner and operator in Finland. The collaboration between Alfons Håkans, with extensive practical experience in harbour tug operations and icebreaking, and Robert Allan Ltd. with its long history of icebreaking vessel and compact icebreaker-tug designs resulted in the development of a unique, high-performance vessel.

These new tugs will be specifically designed for year-round service in the Baltic Sea and particularly in the Northern Baltic Sea which is covered with heavy ice during winter. The TundRA series of tug designs are specially developed for operations in a full range of ice conditions and are uniquely designed for each specific ice class and set of operating conditions.

The tugs for Alfons Håkans, as illustrated on the accompanying general arrangement drawing, will have the following particulars:

  • Length overall: 31.5 m (excluding fenders)
  • Length, summer load WL 29.8 m
  • Breadth, moulded: 12.0 m
  • Depth, moulded: 5.8 m
  • Draft, navigational: 5.6 m
  • Installed Power: 2 x 2000 kW
  • Speed: 13 knots
  • Bollard Pull, min: 67 t
  • Accommodation for: 7 persons
  • Gross Tonnage: 498 (approximate)

The new TundRA 3200 series tugs will be built at Sanmar Shipyards S.A. in Turkey. They will be classed by Bureau Veritas, with the following notation:

✠ Hull, ✠ Mach, Escort Tug, ✠ AUT-UMS, Baltic Service, Ice Class 1A, INWATERSURVEY, Green Passport-EU

These tugs will be capable of performing multiple, diverse tasks, including escort, ship- assist, icebreaking and ice management, open sea towing, fire-fighting, small cargo transfer on deck including 20-foot containers, assistance in salvage, and oil spill recovery. The hull is designed for icebreaking with strength that is significantly above requirements of the prescribed ice class 1A to ensure safety during icebreaking operations and eliminate the possibility of structural damage and shell plate deformation. For ship-assist in berthing and unberthing the tug is fitted with all necessary equipment and fendering for two directional, bow and astern pushing and pulling.
