The fabrication area in Vikkilen includes indoor and outdoor welding and assembly facilities of 11,000 and 5,000 m2 respectively. Total area inclusive storage is 41,000 m2. The quay is equipped with 2 x 60-tonne cranes, and the water depth at quay front is 10 metres. In addition, the fabrication area includes facilities for sandblasting and corrosion protection.


This facility is situated 2 km from the main office on historic ground with links to the Viking era. Fjære was Nymo's first facility back in 1946. The first building is still in use.

The facility has 2.700 m2 indoor workshops for specialised fabrication of stainless steel and aluminium constructions. This includes a separate cleaning shop for passivation of stainless welds.

Eydehavn Yard

The site at Eydehavn was previously an aluminium plant. It was rebuilt as steel construction and shipyard in 1975. AS Nymo took over the site in 1991.

The facilities today comprise main assembly hall 60x30x24m (LxWxH), with 200- and 50- tonne overhead cranes for integration testing of subsea systems, miscellaneous halls for prefabrication and assembly, and sandblasting and painting shops. The 200-tonne crane also serves the outdoor area and reaches 10.5 m outside the quay front for load-out purposes. In addition, the site is equipped with a 25x20m seabed platform at a depth of 10.5 m for shallow water testing and also ground transportation facilities of up to 250 tonnes.

The indoor and outdoor fabrication area is 10,000 m2  and 15,000 m2  respectively of the site's total area of 60,000 m2.

The Eydehavn yard is located in sheltered water with a minimum of 25 m water depth in the sailing route to open sea, and 10m water depth at the 150 m quay front. The distance to open sea is short and without any restriction to vessel or rig sizes.

The yard has a seabed foundation for testing of jack-up rigs.


The company was founded and got named A/S Nymo Fabrikker. Founder was Mr. Alf Ribe, who initially intended to build up a foundry to produce hearths and stoves.
The company’s shares were 100% taken over by the Ugland family.  The purpose by taking over the workshop was to fabricate special items and spare parts for own ships and to provide vessel engineers with required workshop practice necessary for their certification.
The first machine and repair shop were built at Fjære site.  The Ugland owned ship “Lisita” (13 150 DWT) arrived Grimstad, Vikkilen as the first merchant ship to the yard for necessary maintenance and repair.
The first floating dock, which was bought from Denmark arrived Nymo.  Ships up to 16 000 DWT could then be docked.  The dock was in use until 1975 and then sold to Sweden and a new dock was installed.  A/S Nymo Fabrikker was renamed AS Nymo, with subtitle Mekanisk Verksted.
Nymo into the oil age.  Contract was signed for overhaul and upgrade of the drilling rig “Ocean Prince”, and the rig arrived in December.  This was a challenge for Nymo and so far the biggest job ever performed at the yard.  The rig left Grimstad in May 1967 and was the first rig repair performed at any Norwegian yards.
Nymo together with 4 other South Norway yards established the company Oil Industry Services. This was a company specialized in services to the oil market and very soon a module contract was signed for the first platform to Ekofisk 2/4A in 1973.
The expansion of Nymo into the “oil age” started by decision of building quay and shop facilities at the yard in Grimstad.  This was the company’s start of module fabrication and is still the main activities nearly 40 years later.
Nymo fabricated floating platform structure for an Aker H3 to BMV in Bergen.  This year Nymo also delivered the first fabricated accommodation quarter to Eldfisk.
Fabrication and delivery of heavy lift vessel “Uglen”.  The vessel was designed and built in close cooperation with the Ugland organization.
The first EPC contract was signed with BP for design, procurement and fabrication of an accommodation module and helideck for 135 persons to Gyda field.
Nymo acquired the yard facilities at Eydehavn, Arendal.  The first delivery of a complete platform was signed with Elf Petrolan BV, The Netherlands.  This unmanned wellhead platform was hooked up at the K6D field.
From this year subsea projects became a main activity at the Eydehavn yard and two rise towers for the Troll Field were fabricated and delivered.  Further agreement was made to fabricate subsea structures and pipelines for a large number of wells to the Troll oil province.
A 1700 tonnes process module for the Vigdis field was fabricated and delivered to Saga Petroleum. 
Nymo fabricated a complete drilling module (1800 tonnes) for Bentec Norge A/S to Oseberg Sør field.
Nymo’s first EPCI contract was delivered to Hydralift and Stena Drilling. Nymo performed engineering, procurement, fabrication, transport, installation and testing of the drilling module for the rig “Stena Don” which was built in Germany.
One of the most prestigious contracts was signed with ABB to fabricate the subsea units for the Snøhvit field. Nymo’s delivery consists of 6 seabed units containing manifolds and control systems for gas production from 325m of water depth.
In 2005 Nymo signed contract with ORS, later transferred to COSL for design and fabrication for one drilling module with an option for a second identical module. Later another 2 drilling modules and 4 mud modules was ordered.  The contracts also included transport from Grimstad to Yantai, China.  All 4 drilling and mud modules were delivered from 2007 – 2010.
Accommodation modules for 290 persons were fabricated at Eydehavn yard and installed onboard Master Marine’s vessel Service Jack 1 “Haven”.  Final hook-up and completion of the vessel started August 2010 and completed July 2011. “Haven” will serve as accommodation platform in the Norwegian sector of the North Sea.
