Deepwater Trenching

Fugro and Soil Machine Dynamics (SMD) have developed a modular jet trenching and mechanical cutting system. The Q1400 system will be available early this year for applications including offshore oil and gas construction. The system offers a tracked trenching system capable of free flying and operating in water depths of up to 3000 m (9,842 ft). It can perform jet trenching in soils of up to 100 kPa, and mechanical chain cutting in soils of up to 250 kPa. The system consists of a common trenching module and separate tracked jetting and mechanical cutting skids, with a customized launch and recovery system rated to Lloyd’s sea state 6. A deck-transfer skidding system enables mode changes safely at sea without requiring cranes, the companies said.
