Ashtead Technology, Hydrollica to Provide Seawater Tooling Technology
of seawater-powered subsea tooling into Ashtead Technology’s global fleet, including the Hydro Multi-Tool, Hydro Micro Multi-Tool and Hydro PowerPack. These compact yet powerful tools are designed to deliver high performance across a wide range of subsea operations while replacing traditional hydraulic oil with seawater, significantly reducing environmental risk.Unlike traditional hydraulic systems, Hydrollica’s tooling operates using seawater, eliminating the need for hydraulic oil and reducing the risk of contamination. This innovation is particularly relevant as subsea operators across

New Waterjet Cutting, Blasting System for ROVs
pressure waterjet technology.” The 100hp SUB-JET 3000 produces 7.5 liters per minute of 3900 bar ultra-high pressure water for cutting and blasting. It carries 35 liters of abrasive on the skid standard, which provides 30 and 90 minutes of cutting time. The ROV provides hydraulic oil to power the waterjet intensifiers and operate attached tooling, 24 Vdc (300 watts) for control power, and a fiber optic data link to the topside controller. The system requires between 150 and 200 liters per minute of hydraulic oil to run at full capacity but can be operated at lower output
New Subsea Piledriver Uses Seawater
IHC Hydrohammer, part of IHC Merwede has developed and tested a new technology which uses seawater instead of hydraulic oil. This sustainable product development minimises potential oil spill hazards in the marine environment and presents new opportunities for deep-water offshore pile driving that will be beneficial to the future growth of offshore construction. The S-90W IHC Waterhammer has been utilised in conjunction with Swiber Offshore Construction. The installation contractor used the advanced pile-driving hammer to install four foundation piles on the subsea PLEM (pipeline end manifold)
