Efficient solutions offering significant cost savings for operators, shore power providers and shipbuilders while delivering fast and strong performance in a reliable manner.
Compact products do not require heavy foundations which reduce the civil works, often a big expense, to a fraction.
3mar Nector connection devices utilise the optimal connection direction, and are installed on top of the loading ramp.
Competing connecting devices, that are based on rigid ground or on sea bed, need to compensate the vertical movement of the vessel in relation to the dock. A vertical compensation mechanism makes such a device tall, heavy and complicated and consequently requires heavy and costly foundation work.
1. Reshape the landing foundations
2. Block the key side area
3. Touch the seabed
Nector 2000 Automatic Shore Connection Device
Nector shore charging connecting device is installed on the side of the loading ramp connecting fast and following automatically the movements of the water level.
The patented Nector Z-shaped connecting arm is guided by machine vision and has properly fitted tolerences for vessel position variations due to sea state and loading conditions changes - along all the axis and angles around them.
E-Vessel Ellen, the worlds largest and furthest ranging all-electric ferry at the time of her inception in 2019, relies on patented 3MAR connector technology.
"A large and important step towards climate-neutrality."

Due to very different business nature in the Automatic Shore Charging Connection Systems compared to vessels and cruise shipbuilding, it has been decided that a new independent company will be founded. This new company will concentrate in Automatic Shore Charging connections already developed in Mobimar Ltd and to continue this work.
So all knowhow of Automatic Shore Charging Systems has been transferred to 3mar Oy. Simultaneously the Mobimar patents and patent applications have been transferred to 3mar Oy.
Managing director of the new company is Pauli Immonen. He has earlier been Managing Director and owner of Mobimar Ltd for over 25 years.

Markku Hokkanen M.Sc., Naval Architect, has a history in Finnish cruise and ferry new building yards, Kvaerner Masa / Aker yards at the time, at ABB Marine being responsible for sales for cruise vessel segment, starting up the marine system business at Danfoss Editron, Visedo at the time and as an entrepreneur helping out SME companies to establish and develop their sales & project activities within the marine industry. He will be responsible for sales and projects at 3mar.
3mar Ltd will be further strengthening resources to meet the market requirements both in terms of performance and capacity.

The most suitable arrangement for shore charging requires the connecting device to be installed on the side of the loading ramp. Consequent to comprehensive clarifications about the benefits, implications, risks and their mitigations Norwegian road administration Statens Vegvesen has issued Nector a concept approval. Local conditions and existing ramp constructions vary. Verifications of structural strength, capacity of lifting system etc will be done for all projects individually.

3mar Ltd has developed a new revolutionary automooring device. Instead of mounting the unit on the keyside the device is designed to be mounted on the operating vessel.
- The holding power of the gripping magnets is 20 tons per unit, with a good safety margin for that value.
- The design is very slim. Just 0.5 meters. Thus it does not limit the car lanes in typical road and city ferries.
- As the device is mounted on the ferry side no radio link is needed to control the actions.
- Supporting mechanics adapt to the ship movements due to sea state and loading & offloading.
- The unit is based on bi-stable magnets. The permanent magnets do not need electric power to keep their holding power.
- Connection time is just a few seconds.

The first Nector 1000, an uncomparably compact charging connecting device, has been factory acceptance tested and shipped to the customer. End customer project commissioning will be carried out on the first quarter of 2023.
Nector 1000 complements 3mar’s offering of charging connecting devices for the powers below 1,5MW, especially suitable for smaller city & road ferries and heavy duty working machines.
Nector 1000 development was based on well proven solutions of Nector 4000 & Nector 2000, using same components, materials and technology selections simplyfied and scaled down to fit the power, functional requirements and economy of 125-1500 kW applications.
Nector 1000 is AC & DC compatible, can be installed on the vessel side as well and if chosen so deletes the need of wireless communication between the vessel and the port. The device weights less than 400 kg and comes with an option of a fibre optic connection for exchanching information between the shore and the vessel while charging.

Magmoor 20 automatic mooring systems for Weisse Flotte GmbH’s ferries MF Warnow and MF Breitling are due to commissioning this Spring at Warnemunde. The preparations on the shore side were carried out mid December 2022. The installation works of counterplates on existing bollards at ferry berths took less than five hours each and were done during quiet night time hours without disturbance to the traffic which goes on around the clock.
Compact Magmoor 20 automooring system will be installed onboard the ferries where from they reach out towards the counterplates, attach to them with permanent magnets that can be turned on & off and maintain the ferries on their position at berth. No need to push the ferries against the piers with propellers saves money and environment.
The counterplates on the shore side are simple steel structures. No moving parts, no need for radio communication, no energy consumed to maintain the holding force of the magnets.
With our hull a 60m long vessel will easily break a 30m broad fairway through one meter thick ice, which translates into a 40% reduction in hull lenght compared to traditional ice breaking hulls. Imagine the savings you will achieve in daily operations! The patented 3Mar hull has been tested in the arctic laboratory of VTT Technical Research Centre of Finland. It has also been verfied and tested by our partner Aker Arctic.
A unique gripping mechanism for safe embarkation in Hs < 2.5 ma. When combined with a stable trimaran hull on the service boat the safety advantage is even greater.
