The vessel was built in 1985 in Poland in Gdansk Shipyard, as supply vessel. She had a superstructure with navigation deck located on bow section and the engine room located at the midship. Vessel was equipped in towing winches and deck davit. Gepard’s deck was equipped in two powerful foam generators, couple water-foam guns and sea water suction pump diesel engine driven, changing ship into rescue vessel. In 2006 she has been converted in SHIPREPAIR YARD “NAUTA” S.A. in Gdynia. After conversion “Osprey Explorer” became seismic-research vessel.
|The main dimensions:|
|Length o.a||81,16 m|
|Length b.p||71,45 m|
Conversion consisted in vessel adaptation for new tasks set by the Owner. In aft section deck hangar structure with heli-deck was added. Structure according to Vik & Sandvik design was build according DNV regulations and rules. Vessel obtained DNV +1A1 ICE-1C HELI class. During conversion into seismic-research vessel, three high pressure air compressors with driving units, have been installed on deck. Additional, streamer winch with handling system, umbilical winches and seismic equipment handling winches have been installed on hangar-deck. Also superstructure was rebuilt extending her capacity over 6 new accommodation compartments, new instrument room, for seismic equipment, and stores. During conversion 200 tones of new steel was used. Assumption scope of work increased over twice and also took up vessel common systems.
Additional the scope of conversion included:
- vessel adaptation fulfilling SOLAS regulations,
- rebuilding existing piping system as needed,
- rebuilding electric installation,
- connecting new electric generator to Diesel engine, previously driving sea water suction pump,
- assembling computer network and intercom system,
- increasing accommodation/office area and instrument room by superstructure rebuilding,
- accommodation compartments renewal;
- navigation deck upgrading,
- fitting of new fire detection, foam and CO2 system,
- fitting of high pressure air system,
- assembling cranes and FRC davit.
For the conversion the ships steel of A grade was used and works were carried out under supervision of the Classification Society Det Norske Veritas (DNV). Conversion’s technical drawings and technological documentation have been prepared by the Projects Technical Service Department of Shiprepair Yard “NAUTA” S.A. in Gdynia.
