Marin Teknikk’s Multi Hull Design has arrived in Norway!

The first vessel based on Marin Teknikk’s Multi Hull Design (MHD) has been successfully launched at Montex in Polen and arrived at Green Yard Kleven on April 18, for outfitting and final completion.

After years of development, this marks a significant milestone for Marin Teknikk. The project originates from an internal concept that has been further developed through extensive engineering work and validated by three model tests conducted at SINTEF Ocean.

A key feature of the design is Marin Teknikk’s Motion Compensating System (MCS), enabling safe gangway “Walk-to-Work” operations in sea states up to Hs = 4.5 m. ROV operations over the ship’s side for a vessel of L=70m can be done in sea states up to Hs=6m because of reduced vertical Heave velocity.

By significantly reducing vessel motions, the MHD concept improves operability, extends weather windows, and enhances working conditions for both crew and equipment offshore. The system is fully passive, requiring no energy input, contributing to a more sustainable and efficient offshore operation.

In addition to Walk-to-Work vessels, Marin Teknikk is actively developing MHD-based concepts for a wide range of offshore applications, including:

  • Standby and rescue vessels optimized for harsh environments such as the Norwegian Sea, Barents Sea, and areas west of Scotland
  • Subsea construction, IMR, and ROV support vessels with improved lifting and operational performance
  • Seismic node handling vessels
  • Vertical lay vessels for flexible and rigid pipelines (150–650 ton tension capacity), enabling smaller and more cost-efficient vessel designs
  • Cable laying vessels for both communication and power cables
  • Heavy lift vessels with crane capacities up to 5,000 tons SWL
  • Offshore mooring installation vessels
  • Feeder vessels for offshore wind logistics, reducing accelerations from up to 3G (monohull) to below 1.5G in critical routes such as around South Africa
  • Accommodation vessels for up to 400 persons
  • Aquaculture support vessel concepts under development
  • The MHD design also benefits from high bollard pull relative to installed power, achieved through a “4 Prop Drive” configuration with four azimuth thrusters—one in each corner—ensuring optimal thrust distribution without interference.

We look forward to following MT6067, “ELISA” through the final stages and into operation for OMV Petrom.
