Irregular heave motions — Real sea conditions - irregular heave motions

Tested and validated in real sea conditions

At sea, vessels experience irregular and coupled motions, not just the regular sine wave motions used in laboratory tests. That is why we validate our MRUs in real, irregular sea conditions as well as in the lab.

MRU 3000 Subsea, an alternative to DMS-05, DMS-10, DMS-25 and DMS-H

The Teledyne TSS DMS-05, DMS-10, and DMS-25 are depth-rated motion sensors measuring roll, pitch, and heave for hydrographic survey, active heave compensation, and offshore monitoring. The DMS-H is the heave-only variant.

The MRU 3000 Subsea is an alternative for most DMS-05, DMS-10, DMS-25 and DMS-H applications, for many applications, the MRU 3000 Marine would also work well.

Why the MRU 3000 Subsea?

Roll and pitch accuracy: 0.05° RMS, valid across the full range of angles.
Roll and pitch accuracy validated in real, irregular sea states.
Compact, lightweight titanium housing.

High accuracy in a compact form factor

Heave accuracy5 cm / 5 %

VRU 3000 Subsea, an alternative to DMS-RP25 and DMS-RP30

The Teledyne TSS DMS-RP25 and DMS-RP30 are roll and pitch sensors without heave output, available in subsea and surface versions, used for dynamic positioning and roll/pitch monitoring.

The VRU 3000 Subsea is an alternative for most DMS-RP25 and DMS-RP30 applications, for many applications, the VRU 3000 Marine would also work well.

Why the VRU 3000 Subsea?

Retrofit of your MRU

Our MRUs use the latest generation of high-end MEMS sensors with high long-term stability, which makes them well suited for retrofit installations.

Typical retrofit applications are AHC, dynamic positioning and helideck motion monitoring.

You can replace your existing MRU yourself, or use one of our retrofit partners to do the installation for you, subject to vessel class and system integrator requirements.

Where our MRUs are used

What our customers say

"The whole industry is welcoming these MRUs."

Johnny Rabben, CEO, ShoreConnection

Read case study

"We can get a Norwegian Subsea unit that retains adequate precision through the planned life of our systems without the shipowner having to go through the cost or hassle of returning the unit to shore for recalibration every few years."

Karianne Pran, Director of Engineering, Light Structures

"They are rock solid. Many Norwegian Subsea MRUs have been running 24/7 inside Miros products for up to eight years without issue, producing real-time data every second."

Jonas Røstad, Chief Commercial Officer, Miros
