DAMEN makes an impact on ice

Article from Passengership.info

Damen Shipyards Group has won a contract to build an ice ferry for eastern Canada. It also has the LNG and electric markets in its sights, as its director of ferries Henk Grunstra told Rebecca Moore.

DAMEN Shipyards Group has been firing on all cylinders recently within the ferry market. As well as developing fast ferry and LNG-driven ferry prototypes, it has also recently scooped a contract to deliver two ice class ferries that will operate in harsh weather conditions in eastern Canada.

The provincial government of Newfoundland and Labrador has awarded Netherlands-headquartered Damen the construction of two 80m, 14 knot ropax ferries, which will operate on the Fogo Island-Change Islands service and the Bell Island ferry service. Able to carry up to 200 passengers and 60 vehicles, the ropax ferries are due to be delivered in September 2015 and February 2016. The investment is part of the local government’s vessel renewal programme. The first ferry will replace the ageing Captain Earl Windsor vessel.

Damen’s proposal beat more than 10 others for the construction of the ferry. Government representatives visited Damen headquarters and its shipyards. “They got a good feel of what they would get when they went to visit our Galati shipyard, which is where the new ferries will be built, and I think they thought that we were the most favourable in terms of quality,” said product director of ferries, Henk Grunstra. “At Damen, we are not necessarily the cheapest. We do not want to offer the best price, but the best ferry at the best value for money, and so we do not go for lower cost. Instead, we want to be on time and on budget.”

As well as visiting the shipyard where the ferries are to be built, local government representatives viewed some ferries previously built by Damen for the Texel-Den Helder service in the Netherlands. These ferries were built in 2003-2005, are capable of holding 350 cars and 750 passengers and are propelled by a diesel–electric propulsion system.

The design of the ferry for eastern Canada is by naval architects KNUD E. HANSEN of Denmark and has been delivered to the shipyard. At the time of writing the yard was in the process of finishing the design check. The vessel needs to operate in ice that varies between 40cm and 60cm in thickness, which means that ice and cold are the key challenges when it comes to building the vessel, Mr Grunstra said.

Damen is not new to building vessels for such conditions. It has built passenger ferries for icy conditions before – although not for the 1A Super class ice conditions for which this vessel type is being built -and has recently built a cargo ferry for the Swedish Coast Guard that is constructed to 1A Super class standards. “So this is not new to us,” said Mr Grunstra. The shipyard is also not new to the east coast of Canada. It has licensed its Spa 4207 patrol boat design to Irving Shipbuilding for the local construction of mid-shore patrol vessels for the Canadian Coast Guard, and also recently delivered two high-end pontoons to a Canadian operator for deployment at a large offshore project in Newfoundland and Labrador. However, this is Damen’s first ferry project for the east coast of Canada.

Damen does not just build ferries to client prefabrication. It also builds its own models as prototypes that can be modified at the operator’s request. “We build these in series, which gives big cost savings as a benefit,” Mr Grunstra commented. Damen currently has a 40m fast ferry prototype, with capacity for 445 passengers, which has become a standard design in its China-based partner shipyard. Mr Grunstra summed up the major considerations behind its construction: “It had to be one of the most fuel efficient fast ferries ever built. We were very careful about weight. We really needed to get rid of every kilo that was not necessary. We were very good on hull design and also the propulsion installation. But it is important to point out that it is not only the hull, not only the propeller. All these things must be considered together.” He said that the model is very attractive for operators wishing to replace vessels built in the 1990s. “We have done a lot of research on these older vessels,” Mr Grunstra explained. “Our model can carry more people, uses a lot less fuel, needs a lot less maintenance and can comply with safety standards.” He said that vessels built in the 1990s do not necessarily meet current safety standards, as they were built before the current high speed craft Code was in place. Mr Grunstra said: “Some governments do not accept these boats anymore, so we want to provide the answer to replacing these types of vessels.” Another benefit, he pointed out, was that if high speed ferry operators bought Damen’s model, they did not have to wait a few years for delivery, as they were buying it off the shelf. Mr Grunstra added: “The decision process required is made a lot easier if the model is available.”

The model was on the brink of being accepted by an operator at the time of writing.

Damen has also developed an LNG-driven ferry for one of its clients. Although the client is not in a position to buy the design yet, Mr Grunstra said that this was not the main reason to construct the prototype: “The main reason for developing this was to go through all the regulations and learn about the difficulties associated with building an LNG-driven ferry. For example, should it be driven by an AC or a DC grid power system? We put all these theories on the table and came up with a fairly simple result. We felt we needed to make it as simple as possible. Ferries need to operate for 99 per cent of the time, so you have to go for the most reliable, sturdy, strong construction, even when operated with gas as fuel.” Damen will also be using another alternative means of power. It has spoken to a client about developing what it terms a sustainable ferry. The client is keen for Damen to construct such a ferry and Mr Grunstra said that the agreement would be signed very soon. He added that the vessel would be very likely to have electric propulsion, and therefore zero emissions. Damen Ferries accounted for approximately 10 per cent of the shipyard group’s sales turnover in 2013. “We can do more ferry business than this, but we are not a shipyard where we build the cheapest. Rather, we want to build the best and provide the best value for money,” Mr Grunstra stressed.
