LNG-powered newbuildings Bore and Wijnne Barends


As announced in the previous Sustainability Report, the first of seven LNG-powered vessels are being delivered presently. Both Bore and W&B have taken up their first newbuild vessels with their new propulsion systems.

Three 7,000 mt ro/lo vessels are being built for Bore Ltd, while Wijnne Barends will add four 5,800 dwt lo/lo coaster vessels to its fleet. The vessels are specially built to transport paper and forestry products for our longstanding client UPM.

Bore - full ahead, meeting sustainability requirements for the future

Bore’s three newbuildings, scheduled for delivery first half 2022, are prepared for the future with flexibility and optimized ship performance. The vessels will use LNG as primary fuel from the start. The hole propulsion train is optimized for efficient utilization of engine power in all operating conditions. The present day change in technology gives the opportunity to utilize highly developed CFD calculations in areas such as underwater hull lines, propellers and rudder areas etc. The optimized CPP propeller control takes today’s performance control of the vessel to a new dimension; it takes in all influences which have an impact on fuel consumption, such as weather, wind, waves, current and time table etc. All is controlled by a Voyage optimization program which gives a tool for maximum optimization of today and uses historical values for analyses to give input for further improvement of newbuildings and existing ships. Today’s digital platform and ship to shore communication gives an overview that every gram of fuel is utilized to its maximum potential through digital twins, analyses and follow up not only for the ship itself but also for the customer. Due to cargo room environmental supervision and control we can grant sensitive cargo to be transported in the best possible way. The dual fuel engine gives flexibility to utilize future different low emission fuels with minimum changes required onboard. But already today the IMO EEDI requirements for newbuilding during phase 2 (2020-2024) are fulfilled with a big margin; abt 60% better than the required level is a good starting point. That gives confidence for the years to come. Even now, we could start to use a mix of BioLNG, 10%, 20% or even 100% without having to change the installation onboard. This means we will be able to sign up for the best category in sustainable performance with yearly improvements for many years to come. Considering the high cost demanded for producing e-fuel for the future, where the Well-to-Wake energy consumption more than doubles, we take global responsibility for balancing the sustainable transition without compromising emission cutting. Taking GWP to be 100, the total Well to Wake GHG emissions reduction benefits are between 5% -10% for our LNG 4-stroke medium-speed engines on GAS operation compared to ordinary fuel. We fulfil the NOX Tier III level and the methane slip of our engines is down to 3.5 – 4 g/kWh (gives < 1% ) at optimal load, were we strive to be at all times. It is our goal to find ways to establish sustainable shipping with minimal impact on our environment.

Bore's 7,000 dwt ro/lo vessel

Wijnne Barends’ four newbuilding Lady M vessels

For Wijnne Barends, their four new Lady M 5,900 dwt dual fuel vessels, built at Wuhu Shipyard China are being delivered throughout 2022.

These four vessels have been designed to meet future environmental legislations, for which various features have been implemented. By optimizing their hull lines in relation to propeller/nozzle, resistance reduction has been achieved, whereas Dual Fuel (DF) main engines have been used to optimize the use of Bio LNG, Bio Gasoil or even Ammonia and Methanol for future zero emission performance. The vessels’ 200 m3 LNG storage tank is situated below the main deck, which reduces resistance and increases their cargo carrying deck capacity with 25% compared to similar vessels, further enabling the carriage of large project cargoes such as windmill blades with lengths over 80 mtr. Additionally, they have been designed for open top sailing at a draft of 5.5 mtr and provide excellent overview without any obstructions owing to the forward position of the bridge. These vessels' design has been developed for excellent EEDI values of -56.7% below the required EEDI of 15.87 compared to 6.87 g CO2/t nm for this kind of vessels. Their reduced use of auxillary energy is achieved by installation of a heat recovery system from main and auxiliary engines where the heat will be used for hot water systems and heating of the complete accommodation areas incl. the bridge. Besides, they avail over an optimized propulsion train in combination with vessels’ electric load demands under all circumstances and speed, through the use of frequency controlled shaft generators in relation with CPP pitch/revolution optimization.

Furthermore, safe and efficient sailing is enhanced with the optimized route prediction systems installed with weather station, SPOS and acceleration/movement sensors.

Thus, the new Lady M vessels have been built to the maximum possible standards of today.
