ROTTERDAM, the Netherlands -- Van Oord Dredging and Marine Contractors’ first shallow water pipelay vessel has undergone a naming ceremony at the COSCO shipyard in Nantong, China.
The Stingray is designed to install pipelines from 6-60 in. (15.24-152.4 cm) diameter. Van Oord is primarily targeting S-lay in combination with shore approaches and associated activities in water depths of 5-100 m 16.4-328 ft) or more.
Additionally, the vessel can perform light offshore structure installations such as buoys and manifolds, hook-up, commissioning, piling, and midline tie-ins.
Stingray complements Van Oord’s more familiar offshore services, i.e. construction of landfalls, installation of rock, trench dredging and backfilling, and installation of single point mooring (SPM)-systems and gravity based structures (GBS).
The company says that by offering these activities as one integrated package, it will provide a unique one-stop shop concept for shallow water oil and gas developments.
