Atlantic Oceanic LLC
Subsea Mattress Lay
We have two systems capable of subsea mattress lay AND mattress removal.
I-GRAB system: This solution launches one mattress at a time. The IGRAB ROV is attached to the mattress frame and propels mattress into position using the 4 powerful subsea thrusters. The hydraulic power pack then releases the pins on the frame to release the matt in position. The advantage with this system is that a single spread of equipment does the entire job; The ROGE ROV surveys (video / sonar) a pipeline or cable track, and then also lays the Matts and post surveys. One single system does all. Low cost solution with no separate ROV or diver solution required.
MDS 3 system: with the capability to launch and lay three mattress units at the same time. This unit uses 4 powerful subsea thrusters to change the heading and assist to position the matts accurately on the sea floor. Atlantic Discovery or Atlantic Tonjer will operate this system. (Track record: Project Sept 2016, German waters. IGRAB ROV system simultaneously fitted with a cable tracker to assist with post lay burial inspection and mattress survey)
