The concept design for TT-Line’s new dual fuel RoPax ferry has contributions from sister companies OSK-ShipTech and Steen Friis Design – both part of Danish marine consultants OSK Group.

With a particular emphasis on flexibility and fast turn-around in ports, OSK-ShipTech has assisted TT-Line with the concept design for their new Green Ship. The firm contract with Chinese yard Jinling Shipyard for a 230 m RoPax newbuilding also includes an option for a sister ship.

“We are proud to contribute to TT-Line’s fleet development and in addition to developing the concept for this new Green Ship we have been responsible for the contract design as well as basic design,” says Anders Ørgård, CCO of OSK Group.

A five-man marine engineering delegation from Jinling Shipyard and representatives of TT-Line are currently visiting OSK-ShipTech’s premises in Copenhagen fine-tuning the ferry’s design. When complete, the 230 m RoPax with a capacity of 200-plus trucks and 800 passengers will be the most environmentally friendly RoPax ferry in its operating area with an expected 50% emission reduction compared to the previous RoPax generation.

In addition to fuel efficiency, emission reduction, and fast turn-around in ports, emphasis has been put on passenger comfort and further development of the modern sea travel experience. Ship interior designers Steen Friis Design has contributed to the tender interior concept.

Anders Ørgård continues: “This is a prime example of synergy in action and the very reason OSK-ShipTech bought Steen Friis Design back in 2016. With this setup, we can provide our clients with full-line in-house engineering and design solutions – and provide the full integration of ship design with focus on on-board spending and on-board flow leading to enhanced passenger experiences.”

Expected delivery of the new Green Ship is during the course of 2022.

Valmet launches new process control for ships to improve fuel efficiency

Valmet, the Finnish technology group, said it has launched new process control for ships to improve their fuel efficiency. This new control called Valmet DNA Sea Optimal Mode acts as a separate power management mode within the Valmet DNA Power Management System.

Valmet DNA Sea Optimal Mode enables ship owners to achieve up to 3% savings in fuel consumption. The actual savings vary based on the load of the power plant and specific fuel consumption (SFC) profile of the engine. Valmet DNA Sea Optimal Mode has been tested in close cooperation with shipyards and ship owners. It is already in operation on several cruise vessels.

"If we look at the data from tests run on ships, the highest measured saving has been 2.44%, which represents roughly 190 kg of fuel saved per hour," says Andreas Carlsen, Project Manager, Marine Applications, Automation, Valmet.

Valmet DNA Sea Optimal Mode utilizes unbalanced load distribution, taking advantage of the fact that the SFC of each engine varies with the load and has an optimal point of operation. By keeping as many engines as possible at their optimal load, it is possible to optimize the fuel consumption. The optimal load of an engine is the load at which the engine uses the least amount of fuel per kW produced.

To complement the solution, Valmet has developed an optional add-on called Valmet DNA Sea Optimal Mode Advisor. It provides operators with advice regarding mode selection and load priorities.

“We are glad to have signed an agreement with an important partner such as SKF which is a leader in its segment. By working together we can provide a time efficient and valuable service to ship owners. Considering that we have worked with SKF for many years we are confident that this cooperation will be successful and we also plan to initiate the same collaboration with Group’s yards in the next future” says Andrea Sabbion, Sales Manager Commercial Ships Dept., Palumbo Shipyards.

Chantiers de l'Atlantique expands pre-assembly area by 30%

Chantiers de l'Atlantique and the public works company Charier inaugurated on 26 November 2018 the extension of the pre-assembly area which allows a significant increase in the production capacity of the shipyard.

With the work started in July 2017, the yard floor area is now expanded by 17,000sqm, meaning a 30% gain. By lengthening the rail of the 1,400-tonne gantry crane – which is assembling the hull of the large vessels – by 135 m the completed project allows six more mega-blocks to be assembled and outfitted.

"This investment worth €16 million allows us to move to a simultaneous construction capacity of 22 blocks, compared to 16 previously and thus meet the increase in the current and future industrial load of the yard," said Laurent Castaing, General Manager of Chantiers de l’Atlantique.
