Subsea Installation

IHC Hydrohammer, part of IHC Merwede, has successfully used seawater instead of oil as a drive fluid for offshore installation. The Waterhammer technology is a sustainable product development that minimizes potential oil-spill hazards in the marine environment and presents new opportunities for deepwater offshore pile driving for offshore construction. The Model S-90W system was used by Swiber Offshore Construction as its advanced pile-driving hammer to install four foundation piles on the subsea pipeline-end manifold approximately 210 km offshore Mumbai. The 1.1‑m-OD piles were driven into the ­seabed.
