Located in the midst of a landscape of scenic mountains and clean blue waters yet less than an hour’s drive from the international airports Dubrovnik and Tivat, is s’s luxury tourist destination Portonovi. The new Marina Portonovi, designed by Marina Projects based in the United Kingdom and built by Marinetek, is one of the largest nautical destinations in the Mediterranean and a seasonal hot spot for superyachts.

The marina has a total of 238 yacht moorings with lengths of 7 to 70 meters inside a closed basin, with the possibility to accept yachts up to 120 meters long on the outer breakwater.
Boats up to 15 meters in length have berths of Marinetek fingers, while we have offered a standard Mediterranean docking system for larger yachts.

Several types of Marinetek standard pontoon elements were used, from the largest, 4 meters wide Super Yacht pontoons to the last, 2.5 meters wide All-Concrete pontoon.

The entire marina is protected by solid breakwaters on concrete piles to preserve the natural circulation of the water through the marina. As additional wave protection, a 180-metre-long floating breakwater was built in front of the entrance.

A total of 67 pontoons elements with all the additional equipment, installation, and anchoring of all piers with the Seaflex system, as well as installation of the yacht mooring system, was carried out Marinetek’s installation team that is certified for Seaflex anchorage systems.

Marina Bay was completely refurbished. The fixed piers were demolished and replaced with new pontoons and finger moorings for the yachts.

Ocean Village and Super Yacht Marinas extended the berthing capacity in the area with new moorings for Super Yachts up to 100 m.

The new residence area and new marinas with high quality services is Gibraltar´s most desirable visiting point for yachts and tourists.

The first phase of work began in 2016 with the development of the southwest part of the bay, the construction of about 300 meters quay wall, and the installation of a floating breakwater and five floating piers. The project was divided to five phases, and through 5 years of development, the municipal port was built to its current form.

For this purpose, Marinetek delivered 9 Breakwater Pontoon elements with a total length of 164 meters, and 44 All-Concrete Pontoon elements with access bridges, mooring devices, and infrastructure, which formed 12 piers with a total length of 735 meters. A quay wall with a total length of 955 meters, a slip and a crane for boats, and a space for a dry berth of about 6,000 m2 have been constructed.

With the final installment of the port of Vrnaža, the town of Šibenik and its inhabitants received a state-of-the-art port for over 700 vessels exclusively for the personal needs of the citizens, sports, and leisure. The port itself is undoubtedly one of the most beautiful and safest ports in this part of the Mediterranean and has already become a meeting place for citizens, and a promenade for families with children during the day. Strict measures for environment protective measures have been introduced for the service and maintenance of vessels.

The new harbor consists of a 100-meter-long floating breakwater, located on the northeast coast of the harbor, and two 60-meter-long floating docks, placed in the protected area. Access to the breakwater is provided by a bridge from the shore, and the docks are accessible by bridges from the breakwater. The piers are anchored with a chain system and anchor blocks, and for all moored vessels, a standard four-berth system with two anchor lines for each vessel was set up.

As the harbor itself is naturally well protected, type M3820BR breakwaters were used to form the breakwater, and 2.7 m wide Marinetek Heavy Duty pontoons M2715HD were used for the interior docks. The entire project was completed in just three months, to the satisfaction of investors and the local population.

The mooring for the boats is provided on both sides of the main pontoon, which runs parallel to the shoreline, and is divided into 4 segments and connected by associated footbridges. The angled mooring fingers have been mounted pointing slightly downstream at 70° angle from the main dock to create less resistance to the river flow.

The second pontoon gate, which is 60 meters long was set up as protection from alluvium and ice, and it also serves as a base for a 27.5-meter-long bridge.

Since the marina is located on the Danube River, with more than six meters of water level fluctuation, it was necessary to design and implement a suitable and secure anchoring for the entire structure. The installation of the pontoon was carried out by mounting 27 steel pilots with an external diameter of 508 mm and a wall thickness of 25 mm. The pilots are made of corrosion resistant steel, while the pilot’s interior is filled with concrete for additional strength. The overall height of the pilots is 23.6 metres. The pontoons are mounted on pilots with special clamps with sliding elements to ensure the unobstructed lifting and lowering of the gates at maximum load.

Marinetek has completed the design, delivery, and installation of four floating pontoon piers of 57 m, 69 m, 75 m, and 54 m and their equipment and anchor system. All docks are made of Marinetek Heavy Duty Pontoon elements, with a total width of 3.3 m. Pontons are also equipped with high-quality WPC decking in two shades of grey color. The fenders are made of elastic PE in the color of the walking surface.

The piers are equipped with access bridges 1.2 m wide and 6 m long with gates and stainless steel rails, and the same WPC cover as on the pontoons.

The docks are fitted with stainless steel mooring pylons in appropriate size and all the equipment and materials necessary to ensure the stability and safety of the pontoons and yachts.

For the anchoring of the pontoons, a standard system with mooring chains and anchorages were used in accordance to the technical requests of the CRS. A Mediterranean mooring system was installed to anchor the yachts.

Due to all pontoon elements and equipment dilapidation, Marinetek has replaced all existing floating piers with new concrete pontoons with additional equipment, cleats, wooden bumpers and access bridges. In addition to replacing the complete pontoon system, in cooperation with the company Dubina Inženjering from Split and Elektrolux TS from Šibenik, the installation of anchoring systems piers and vessels, and the construction of a new water supply network and electrical installation was completed.

Along with standard concrete anchor blocks, in smaller depths, we used geotechnical anchors to meet the requrements for boat sizes and capacity. Another special solution is the anchoring system of pier “V” which is placed in a parallel line with the mound-breakwater and anchored by a system of steel galvanized carriers and with diagonal stainless steel cables to take over the longitudinal forces. Steel supporters are fastened on land with pre-made concrete reinforcements, and on the pontoon with special receptors that were built into the pontoon during production.

For the anchoring system of vessels, we used standard quarter mooring. In line with the needs of the planned vessels and the existing network capacities, a new project for electricity distribution on the piers was created.

Also, new service cabinets (type Tango) with adequate connections were installed.

Marinetek as a contractor was responsible for the construction and supply of a total of 6 floating piers of a total length of 600 meters, with approximately 500 berths for boats owned by local people. This valuable project is among few in Croatia that solve the problem of the constant demand of the local population for communal berths.

Works on the pontoon installation were entrusted to the company Marine Sub d.o.o. from Sibenik.

The anchoring system of piers was conducted using reinforced concrete anchor blocks and a Seaflex system, which makes the floating docks extremely stable with minimal horizontal shifts.

Since the project of anchoring piers and vessels was made based on a coastal promenade along the coast of Gruž, we had to carry out a temporary solution so all the piers could have safe and unhindered access. Till the reconstruction of the shore was finished, we derived steel galvanized bridges at the point based on AB blocks at the seabed.

The surface of all pontoons piers is covered with exotic wood, which gives the marina an exceptional and exclusive look.

For this project, Marinetek produced and delivered 9 Heavy Duty Pontoons, 20 All Concrete Pontoons, and 16 Breakwater Pontoons that formed 5 piers.

The installation of the pontoons and the mooring system was entrusted to the company Hidroinženjering from Rijeka, an experienced team specialized in underwater works. The construction and delivery of service cabinets were arranged by another manufacturer from Croatia – company Marex elektrostroj from Zadar.

The special feature of this project is the anchoring of breakwater elements at depths of up to 20 m and the optimization and flexible anchoring of ships by the needs of the marina, depending on whether it is a constant annual mooring station or for transit ships. Despite the considerable depth, all piers are anchored with a chain, catenary standard system. Since most of the area is relatively shallow, the marina had to be deepened to a depth of at least 3 meters.

Previous concrete piers were demolished and replaced with the new highest-quality floating concrete pontoons. The width of the piers and their spacing were designed to accept larger vessels. The entire infrastructure was changed, as well as all access piers, the electrical and water supply installations and fire-fighting equipment. Old concrete service cabinets were replaced with new and modern stainless-steel cabinets.

Demolition work on old concrete piers began immediately after signing the contract, in mid-November 2015, and the installation of three completely new floating pontoon docks was completed by the Christmas of that year.

The explicit request of the client was that the “main activity of marina can’t stop”, so all works were performed in sequences, pier by pier, moving vessels from the old piers to new ones. This extremely demanding organizational task was done in cooperation with BSK commerce from Rijeka, Rc Neptun from Šibenik, and Marex elektrostroj from Zadar.
