The Oceanjet 900 trenching system (formally ROTS II), in its original specification, offered a reliable and proven high trenching performance using its 900 kW output power, and has performed trenching operations on a variety of products; including power cable, umbilicals, and pipelines of 14" diameter in varying soils conditions.

During 1st & 2nd quarter 2007, Oceanteam have made significant improvements to the original specification to further enhance trenching performance; in line with present and predicted Client requirements, particularly of larger diameter products. Improvements include complete redesign of jetting swords, modification to vary flow and pressure, control system upgrade and the addition of a modified skid arrangement to allow operation on pipelines. Oceanjet 900 has a burial/deburial capacity of nominal 0.5 - 2.0 metres depth, with variable trenching width of nominal 0.05 - 0.7 metres utilizing 2m swords. Oceanjet 900 has successfully completed post lay trenching of some 45km of export and infield power cables on a recent Wind farm Project. In addition the OJ900 has also recently completed successfully a 12" and 14" pipeline burial project.
