Precision subsea excavator and tool-carrier - Dredgepoint

Precision subsea excavator and tool-carrierThe Scanmaskin tool-carrying systems are designed for implementing dredging, excavator, cutting,and various other hydraulically operated tools. They have been successfully deployed in many deep,shallow, harsh water, high current, and low visibility underwater construction activities such as:• Subsea precision excavation in connection with repairs, hot-tapping,pile cutting, and inspection• Levelling and modification of seabed(rock dump, hard and soft clays, and soils)• Rock dump, drillcut, boulder, and debris removal/relocation• Pipeline and cable deburial, maintenance, location, and inspection• Grouting removal• Trenching tasks• Assistance and preparation for installation and decommissioningof platforms and subsea assets• Near shore programs (such as precision drilling in preparationfor blasting and High Voltage cable repair)Gismerøyveien 207NO-4515 MandalTel.: +47 38 27 81 00Fax: +47 38 27 81 01postmaster@scanmudring.noThe Scanmaskin subsea excavator and tool-carrier systems are based on modified excavatorscombined with state of the art ROV technologies with open tool interfaces. This combinationharnesses the experience of both the advanced subsea technologies and the ruggednessof land based construction machines.The Scanmaskin systems are designed for rapid mobilisation and opetation in water depthsup to 1000m. A special monitoring system (MoS), enables safer operation and improved productivityin poor visibility applications. This is most valuable when operating close to live assets or in projectsrequiring the combination of power and precision.The excavation capability in hard soil is excellent. Our hydraulic drum cutter has been successfultested on concrete slabs with hardness of about 15 MPa.www.scanmudring.no

For project estimates a general removal capacity about 2-3 per cent should be expected. In order to achieve an efficientcapacity, it is recommended to use an ejectors size about twice the average size of the items to be relocated.*** Subject to system tool and project configuration. Different umbilical winches and container spreads will have an effect.Gismerøyveien 207, NO-4515 Mandal, Tel.: +47 38 27 81 00, Fax: +47 38 27 81 01, E-mail: postmaster@scanmudring.nowww.scanmudring.no
