Vuyk Engineering launches new EFTVLast updated one year ago
The ship is a real workhorse. This is the starting point of the new EFTV. The design features two cranes with a lifting capacity of 800 tonnes each. In order to achieve lower fuel consumption, the vessel has a small beam. And additionally, a maximum deck size has been taken into account.
Following the requirement of having a large deck area and a reduced beam, a smart solution was initially found in the hullshape. The shape combines a reduced beam on the waterline, resulting in lower fuel consumption, with a large deck area. This reduced beam is the perfect trade-off between low fuel cost and heavy loading. Significant fuel savings can be achieved compared to existing, comparable vessels at the same speed. Considering a common rating of 85% MCR, the EFTV consumes about 25% fuel per mile less at a reduced sailing speed. With this energy-efficient design, the vessel scores well below the future lowest EEDI levels.
Speed up port operations
Besides features for reducing fuel consumption smart solutions are investigated to speed up port operations. The EFTV will be equipped with an automated stabilizer pontoon. This is a very effective way to increase the stability of the ship for hoisting operations while maintaining the reduced beam for sailing. The stabilizing pontoon is placed in front the of the cargo space, to keep the cargo deck as large as possible and clear of any obstacles. It can be launched with an automatic system, completely operated independent to the cargo cranes. It is considered an inherently safe operation for the crew.
Furthermore, a tweendeck handling system is placed in the cargo hold below the main hatches. This makes it possible to handle the tweendeck hatches independent to the cargo cranes, and therefore without the need of opening the main hatches. Tweendeck handling is done by an overhead crane in the hold. The crane can also be used for handling small parts, again independently to deck cranes and main hatches. The tweendeck handling system is combined with a piggy-back system to handle the main hatches. With this automated system, hatch handling operations can even start before entering port, reducing the time in port considerably.
Due to these solutions, a large flexibility is created for handling both tweendeck hatches and main hatches. This gives the opportunity to speed up the port operations significantly by handling things simultaneously. The automatic stabilizing pontoon will be easy to handle and can be operated by just one man from the navigation bridge. Re-positioning is no longer needed due to the depth of the pontoon.
Strong points of the concept are:
- Davit launched stabilizer pontoon, push button controlled
- Flush and clear deck from stern to deckhouse
- Tweendeck handling system with auxiliary hoist in hold space
- Main hatch transport system (extension of tween deck handling system) with stacking system
- Reduced fuel consumption, meeting the lowest EEDI levels
- Increased safety during handling of flipper and hatches.
