Remote Valve Control system for first Turkish ERRV

Last year, the Turkish Directorate General of Coastal Safety launched the Emergency Response & Rescue Vessel (ERRV). The vessel is called 'Nene Hatun', it is nearly 90 metres long and it was built by Sefine Shipyard, which has its headquarters in Istanbul. Econosto was awarded the contract for supplying a comprehensive Remote Valve Control System through good cooperation with Nemomarin, Econosto's agent in Turkey.

About Sefine Shipyard

Sefine Shipyard was founded in 2005 and is located in Yalova, in the northwest of Turkey. The shipyard covers an area of 140,000 m2, which makes it one of the largest shipyards in the region. The company is active in new construction, reconstruction and repair of ships and to this end its shipyard includes a full service design department, various assembly halls, a dry dock (240 x 42 x 9 m) for repairs, a slipway (160 x 60 m) and two quays (total 650 m), with a total capacity of eight ships. Sefine designs and builds vessels in all categories, including cargo vessels, tugboats, ferries, MPVs and ERRVs.

‘Nene Hatun’: a critical role in crisis situations

'Nene Hatun' is the first Turkish ERRV and it was built to play a leading role in various crisis situations. Turkey wants to be able to deploy the state-of-the-art vessel, in local and international waters for:

  • towage services and marine salvage
  • rescue and evacuation of drowning persons
  • medical care (24/7)
  • fire fighting
  • prevention of oil pollution
  • analysis of oil-contaminated sea water
  • diving services and helicopter services
  • offshore command and control centre

Excellent cooperation between Sefine Shipyard and Econosto

Econosto supplied a comprehensive Remote Valve Control System for 'Nene Hatun'. Delivery included a series of Econ valves, in combination with the new Econ EDH Helical actuators for the complete ballast system. All valve-actuator combinations are connected to a Remote Valve Control (RVC) control panel, including PLC with Ethernet connection, which also formed a part of the delivery. The RVC cabinet with PLC is capable of communicating with the central control system of the vessel. Following constructive dialogue between the shipyard and the engineers at Econosto it was decided to deliver the entire installation plug and play in order to ensure smooth assembly and faultless operation.


"Econosto is always an option for Sefine Shipyard"

Mr Serhat Senol, Shipbuilding & Ocean Engineer at the purchasing department of Sefine Shipyard, had the following to say about collaboration with Econosto: "We got to know Econosto as a company that stands apart from the rest through product quality, continuous support and customer satisfaction. Econosto have also responded appropriately to various problems during the construction process and they were capable of quickly providing appropriate solutions. We will definitely keep this in mind when we have new projects available for tender. I can therefore say with confidence that Econosto will always be an option for Sefine Shipyard, both at present and in future!"
