Originally built in 2000 and converted for its current role in 2009 and 2022, the vessel features a cargo capacity of 15,000 tonnes and a rock dumping capacity of approximately 2,000 tonnes per hour. It is equipped with advanced systems, including a dynamic positioning (DP2) setup for stability, a moonpool and side dumping capability, and a fall pipe ROT (Remote Operated Tool) system with a 700 mm inner diameter capable of operating at depths down to 500 meters. The vessel measures 147.24 meters in length with a breadth of 36 meters, and utilizes a robust propulsion configuration consisting of 13,640 kW of installed power, including azimuth thrusters and bow thrusters, to maintain operational efficiency. This technical documentation provides essential physical parameters and operational capabilities for project planning and subsea construction support.","EQUIPMENT SHEET  \nSEAPIPER  \nSUBSEA ROCK INSTALLATION VESSEL  \n| CONSTRUCTION / CLASSIFICATION |  |  |\n| --- | --- | --- |\n| Vessel built by | Jinling Shipyard |  |\n| Year of construction | 2000 |  |\n| Year of conversion | 2009 |  |\n| Vessel converted to FPV by ST Marine - Singapore |  |  |\n| Year of conversion to FPV |  | 2022 |\n| Classification |  | Bureau Veritas |\n| Registration/flag |  | Cyprus |\n| FEATURES |  |  |\n| Rock dumping capacity abt. 2,000 t/h |  |  |\n| Rock installation depth of 500 m through fall pipe with inner diameter of 700 mm |  |  |\n| Accommodation on fore ship, total 45 persons |  |  |\n| Rock dumping system with moonpool and side dumping capability |  |  |\n| Fall pipe ROT - (Remote Operated Tool) with +/- 120 degree rotating deflector |  |  |\n| OPTIONAL |  |  |\n| Fallpipe with inner diameter 1,000 mm with dumping depth approx. 70 m |  |  |\n| Inclined fall pipe |  |  |\n\nSolid ballasting unit  \n\n| MAIN DATA |  |\n| --- | --- |\n| Length overall | 147.24 m |\n| Breadth | 36.00 m |\n| Moulded depth | 9.00 m |\n| Design draught (loaded) | 6.76 m |\n| Dynamic Positioning system | DP2 |\n| Positioning system | DGPS, HIPAP, Fanbeam |\n| Cargo carrying capacity | 15,000 t |\n| Sailing speed loaded | 11.50 kn |\n| Total installed power | 13,640 kW |\n| Main engines | 3 x 3,840 kW (3 x main generator sets) |\n| Main propellers | 2 x 4,500 kW\u003Cbr>(2 x azimuth thrusters) |\n| Azimuth thrusters | 2 x 1,000 kW (2 x retractable thrusters) |\n\nBow thruster  \n1 x 1,500 kW with CPP  \nSEAPIPER  \nSUBSEA ROCK INSTALLATION VESSEL  \n05 — 2023 The informrma t ion conon at ined in this daata sheee t is for guidance purposes on ly and may be sub j ct to changenges lis. © Bos as ak l .
