New superyacht haven in Greek isles

GREECE: Marina Porto Heli, a new marina located southwest of Athens in the islands of the Saronic Gulf, is now welcoming yachts up to 55m (180ft). Built within a naturally sheltered bay, it has capacity for 149 vessels.

Construction, undertaken by the floating pontoon department at Ellaktor Group company Tomi, was challenging. This was primarily due to shallow water near the west and east walkways and the extensive utility ductwork needed to service superyachts. The depth issue was easily overcome with a 300m (980ft) SF Marina concrete dock system.
The pontoon layout consists of two arms. Both begin in the shallow areas with SF Marina type SF1240 pontoons. With a height of only 1.2m (4ft) and a freeboard of less than 0.6m (2ft), they provide ample space beneath the docks for secure mooring. After angling inwards, SF400 pontoons are used.
On the east side, the arm continues with SF1260 pontoons and SF1240 models used for storage. Each of the two arrays has a pair of interior docks comprising SF STD 2.4 units.
The greater challenge was the extensive network of 30 utility ducts. SF Marina engineers designed large EM boxes and a unique channel at the ends of each pontoon with the ability to cross the network around the centre connectors. Currently, the ductwork system contains 16A-125A electrical, potable water and communication cables, as well as pump-out. Plans are being finalised to include fuel service.
“Once our interior marine department offloaded the pontoon sections with a floating crane, they were easy to install,” said Nikolas Aslanidis, manager of the floating pontoon department at Tomi. “The marina owner is very satisfied with the results and we are already in discussion on a second nearby project at Ermioni Port.”
