Offshore vessels

Arctech has a strong knowledge in building of multifunctional icebreaking offshore vessels. Currently the order book includes four icebreaking supply and stand-by vessels (NB 511-514). In 2012 and 2013 Arctech delivered sister vessels Vitus Bering and Aleksey Chirikov to Russia´s largest shipping company Sovcomflot. The vessels are at the moment operating in Sakhalin-1 Arkutun-Dagi gas field. Year 2005 Fesco Sakhalin was delivered to Russian Far East Shipping Company. The vessel was purchased by Sovcomflot and renamed to SCF Sakhalin in 2010.

LNG-powered icebreaker

In September 2016 Arctech delivered the new Finnish icebreaker Polaris. The icebreaker is powered by both diesel and LNG, i.e. liquefied natural gas, which reduces both emissions and fuel costs. The icebreaker will be the first LNG-powered icebreaker in the world.

Oblique icebreaker

In 2014 Arctech delivered the icebreaking multipurpose emergency and rescue vessel Baltika, which is also known as the first oblique icebreaker in the world. The vessel features a patented oblique design with asymmetric hull and three azimuthing propulsors, which allow the vessel to operate efficiently ahead, astern and obliquely (sideways). The vessel can proceed on a continuous mode in 1.0 m thick level ice both ahead and astern and in oblique mode she will be able to generate 50 m wide channel in 0.6 m level ice.

The concept of double acting ship

During extensive common ice-test trials with Finnish Neste Shipping tankers, was found out that vessels with azimuthing propulsion were able to pass ice far easier stern ahead. The vessel that was optimised to operate bow first in open water and stern first in heavy ice conditions, was named Double Acting Ship.

Special JV-company, Nemark, was formed in 1990’s between Helsinki shipyard, Neste Shipping, two Russian shipping companies and the Transport Ministry of Russian Federation to be able to test this concept also in Russian Northern Sea Route – tests were carried out with excellent results.

Nuclear powered icebreakers

Russia has a powerful fleet of icebreakers powered by nuclear energy for the most severe conditions in the Arctic. Two of the fleet were built in Helsinki. They are to operate also in rivers and are thus requested to be shallow drafted (8 m). The projects were carried out as unprecedented Russian – Finnish cooperation efforts with design institutes, suppliers and shipyards.

Taimyr and Vaygach, delivered in 1988 and 1989, are the first nuclear powered icebreakers built outside Russia. Vessels were built ready in Finland excluding the reactor power plant that was assembled in Russia after the delivery.

Shallow draft icebreakers

The need to operate in arctic rivers and for example in shallow Caspian Sea waters has challenged the shipyards design over the years. Several series of shallow draft icebreakers have been delivered especially in 1980’s and 90’s.

Electrical podded propulsion system

The electrical podded propulsion system was developed in cooperation with Finnish Maritime Administration and ABB. Today the system is known as Azipod®.
