MISSIONS
One vehicle, four kinds of work.
Swap the payload and the mission plan, not the vehicle. The same K6 inspects pipelines on Monday and maps wind-farm scour on Friday.
Pipeline inspection
Fly 40 km of export line in a single dive. K6 tracks the pipe, measures burial depth and flags every free span longer than 2 m.
40 km per diveScour surveys
Map the rock armour around each monopile and see where the current has dug in, turbine by turbine, without a vessel on site.
60 foundations a weekSeep monitoring
Revisit the same methane seeps every month and log plume height, flow and sediment change against a fixed baseline.
±5 cm repeatabilityDebris and lost cargo
Search a box of seabed lane by lane, classify contacts on board and send back positions the recovery crew can trust.

Survey-grade sonar in one bay.
THE VEHICLE
Six modules. One afternoon to swap a payload.
Every K6 section is a sealed, pressure-rated module with the same wet-mate connectors. Change the payload bay for a laser scanner or a water sampler on the quayside, not in a factory.

IMAGING
At 1,240 metres the camera sees blue. The report shows rust.
Water eats red light within metres. K6 lights the scene itself, then corrects every frame on board using the measured distance to the seabed, so inspectors read coating damage in true colour.

OPERATIONS
Fourteen vehicles at work on four continents.
Every K6 reports to the Aberdeen operations room over Iridium when it surfaces. One pilot supervises up to six vehicles; the rest of the team plans the next dive.

— CAREERS
Build machines that work where people can’t.
We are 64 engineers, pilots and surveyors in Aberdeen, Bergen and Houston. Most of us have spent time offshore; all of us would rather send a robot.
