Croatian military vessels in overhaul

Sometimes even Croatian military vessels need to halt their patrols and tasks in order to be inspected and have their ship machinery overhauled. For this reason, three ships from the fleet of the Ministry of Defence of the Republic of Croatia sailed into the Trogir docks - the patrol ship Šolta and two missile ships, Šibenik and Kralj Dmitar Zvonimir.
On all three ships, the hulls, decks and superstructures will be cleaned, painted and inspected, and the zinc anodes replaced. The drinking water tanks and fuel tanks will be repaired, works on the intake strainers, shaft lines of the propeller shaft, rudders with the steering gears and pumps will be carried out, and electric works on the main and auxiliary plates and accumulators will be carried out.
The repair works on the missile ships Šibenik and Kralj Dmitar Zvonimir will be somewhat more comprehensive. The sea-water and air systems, the main engines, blow-off system, gas turbines, fuels with coolers, ventilation and air-conditioning, the steering and signalization systems as well as the electric-power supply system will be serviced, whereas on the missile ship Kralj Dmitar Zvonimir the sea-water system for the cooling of the shaft and fuel separators will also be serviced.
The ships will remain in overhaul for about a month.
The patrol ship Šolta was built in Kraljevica in 1982. It is 32.43 m long, 6.75 m wide, and has a draught of about 1.7m. It is propelled by two SEMT - Pielstick 12PA4V200VGDS diesel engines with a maximum speed of up to 26 knots. The ship has a crew of 22 people.
The missile ship (RTOP-12) Kralj Dmitar Zvonimir is 54.24 m long, 8.66 m wide and 2.90 m long. The ship is propelled by three diesel engines of 5,000 HP each. It maximum speed is 37.8 knots, and optimal speed between 32 and 34 knots, whereby it uses 2,500 litres of fuel per hour. it can tolerate waves of up to six meters in height.
The primarily weapons of the ship are eight RBS 15 antiship missiles, and a Bofors SAK 57 L70 gun located on the bow, intended for the elimination of air targets, although it can also aim targets ashore and in the sea. The propulsion and ship systems surveillance system is completely digitised.
The ship crew has 34 members: 6 officers, 20 petty officers and 8 sailors.
The missile ship (RTOP-21) Šibenik is somewhat smaller than the missile ship Kralj Dmitar Zvonimir. It is 44.99 m long, 8.5 m wide and has a draught of 1.8 m. It uses a combined propulsion system: two Rolls-Royce Marine Proteus 52 M/ 558 gas turbines, each with a power of 3309 KW/4500 HP) and two MTU 16 V 538 TB91diesel engines, each with a power of 2647 kW/3600 HP. The diesel engines are the main power unit and are used for navigation under normal conditions, whereas the gas turbines are intended for greater speeds required in conflict.
On the stern section of the missile ship, two launchers for Saab RBS 15 antiship missiles are located, with a total of four missiles, each with a 80 kilometre reach. The stern gun is a AK-630M six barrel rotating cannon with a calibre of 30 mm, and the bow gun is a Bofor cannon with a calibre of 57 mm, intended for the elimination of targets at sea, in the air and ashore. The firing speed is 200 bullets per minute, and the effective reach is 12 km for surface targets, and 6,500 m for air targets.
