Seatools
Builds subsea and marine systems such as ROV tooling, sensor systems, and specialized equipment for offshore operations.
Seatools is a Netherlands-based subsea technology company that designs and builds custom-made equipment and control systems for offshore and underwater work. The business is organised around bespoke problem solving: it takes on subsea challenges ranging from simple to highly complex, accommodates all required engineering disciplines in-house, and works from a stated focus on simplicity, standardisation and advanced simulation so that systems arrive as first-time-right solutions that reduce on-site experimenting and commissioning time. Its solution categories span advanced simulations and control engineering, ROVs, dredging monitoring and control, heave compensation, mass flow excavation, offshore and subsea installation, subsea cable and pipeline installation, subsea cleaning, subsea cutting, subsea electronics, subsea excavation, subsea HPUs, subsea hydraulics, subsea monitoring and control, subsea rock installation, subsea trenching, taut wires, and subsea pressure compensation and subsea storage. Alongside complete systems the company supplies subsea components as standalone items, including subsea pressure sensors, proximity sensors, inclinometers, rotation sensors, compensators and wire length measurement sensors. Its delivered work gives a sense of the range. Seatools has built a series of fall pipe ROVs and matching fall pipe ROV simulators, along with rock installation tooling such as the Stone Dump Tool and inclined fall pipe instrumentation. Excavation and trenching projects include the Basic Mass Flow Excavator, the Deep Water Excavation Grab, the Jetting Bull subsea cable trencher and the Subsea Pipeline Trencher known as Arthropod 600. Installation and monitoring work covers a jacket upending monitoring system, a compliant tower leveling system, a template leveling system, a pile installation frame, pipe and cable departure monitors, a Touch Down Monitoring System, piling hammer instrumentation and control, and a mooring monitoring system. Motion control and access products include the Heave Compensated Gangway Control System designated OAS and its second version, a retrofit conversion of a passive heave compensated LARS to an active one, and towing winch simulation and controller studies. Other named deliverables include the Subsea Diamond Wire Saw called Barracuda, a multi-purpose inspection ROV, a Tunnel Segment Measurement System, an umbilical CT winch, subsea mining vehicle equipment, suction relief valve power packs and ultra-long lifetime compensators. The company also completed a remote offshore monitoring system for The Ocean Cleanup, handling the development, manufacturing and testing of a system that processes, stores and transfers data gathered by scores of sensors linked to five solar-powered electronic pods, which communicate over a WiFi mesh network and satellite connection so the system can be monitored remotely and data retrieved in real time. Seatools sells from an office in the Netherlands and runs an emergency service line outside office hours.
