A fabulous frame structure

Femkuber has recently finalised a lateral torsional buckling study of a truss frame for a temporary building (tent). The tent is composed of a load carrying truss frame made from hot-dipped galvanised steel and a technical fabric protecting the inside from the environment.

The work was performed as a combination of modal analyses to establish the most likely buckling shape and a non-linear load capacity analysis including initial deformation shapes based on modal analysis. All calculations are in line with DNVGL-RP-C208 for determination of structural capacity by Non-linear FE analysis Methods.

We Wish you a Merry Christmas!

With the Christmas holiday nearly upon us and the end to 2016 fast approaching, Femkuber wants to take this opportunity to thank all of our clients, partners and friends!

We are grateful for your continued support, friendship and confidence in us.

As you all know, 2016 has been a turbulent year in the industry. We have seen friends and former colleagues lose their jobs, and we have seen startups fighting to survive.

Most of all, it is both sad and infuriating to see so many smart, kind, highly competent and hard working engineers struggling, while we can do nothing but watch. You should know that we would like nothing more than for you to join our team at Femkuber.

In times of these, it is important to look ahead. 2017 already shapes up to be an interesting year for Femkuber. Our involvement in the tidal power industry grows significantly as Tidetec reaches new heights, our push towards land based industries bears fruit, and hopefully the oil price will stabilise at a higher level. Stay tuned for more news in the upcoming year!

We wish you a Merry Christmas and a Prosperous New Year.

Successful Installation of Tidetec Turbine Prototype in Svelvik

Femkuber has previously performed a lift analysis of a prototype turbine for Tidetec, and on Wednesday 21st of September it was time for “lift off” and installation of the prototype in Svelvikstrømmen, a 30 minute drive south from Drammen. Femkuber was on-site to support Tidetec and document the lift. 

The lift operation was scheduled to start at 09:00 AM when the tidal current was at its weakest. The prototype turbine is fixed to a steel lifting frame designed according to DNVGL-ST-E273 Portable Offshore Units, utilising four lifting points. The lift was performed by Nordic Cranes.

The lift operation was completed on time, according to plan and without incidents, which meant a successful lift for Tidetec and Femkuber!

UPDATE: Teknisk Ukeblad has written an article about the event! Read it here.

Adam Olsson is joining us in our new offices!

FEMKUBER is expanding and we are delighted to announce that Adam, a skilled and talented structural engineer has joined our team!

He has a background from the Swedish automotive industry and from the subsea industry working for Kongsberg Oil and Gas Technologies.

Adam has a solid experience from working as a structural engineer in large EPC projects such as Hibernia, Wheatstone and Polarled. He has grasped the role as project engineer and technical lead during the development of the Subsea Storage Unit now under ownership by National Oilwell Varco.

With his sense for quality and humor, Femkuber expects him to be a vital part of the team. We look forward to working with you yet again!

A lot has happened since we last spoke...

Since our last journal entry in May 2015, business has been booming and Femkuber has been growing. Here is a short summary:

  • Femkuber has entered the green tech industry after having contributed to the development of Titetec's patented horizontal turning mechanism for tidal turbines 
  • Femkuber has also become an active owner in Tidetec and hence reinforced its ambition to become a vital contributor to the development of sustainable energy production
  • Femkuber has performed analyses and verification of equipment to be mounted on the rotational moulded plastic boat Pioner produced by Cipax. This also included writing test procedures and supervision of the test execution
  • Femkuber has performed analyses of a separator steel tank for pit testing
  • Femkuber has performed blast and in-place analyses of several SIP-modules, the largest consisting of 18 off 40ft standard ISO-containers
  • Femkuber has performed analyses of a hot tap tee anchor clamp to be installed on the Johan Sverdrup export line
  • Femkuber is presently engaged in hydrodynamic analyses for a riser cleaning tool, and will continue with global and local analyses of it
  • Femkuber has verified and analysed sea-fastening and installation equipment for the Ivar Aasen cable lay project
  • Femkuber has performed analyses of deck handling clamps and hang-off clamps for Trelleborg flexible risers (Trelline DN600 and DN500)
  • Femkuber has performed fatigue analyses of pot bearings to support vertical loads of up to 2800 tonnes for the Kaombo project
  • Femkuber has moved into new and appealing offices located at the beautiful Skøyen Hovedgård. In addition to four regular work places, it also facilitates a client office, a meeting room and a fully equipped kitchen
  • Femkuber is delighted to announce that we will expand our team by another excellent engineer by September 1st, 2016

We believe that the above illustrates our passion and devotion to engineering in a variety of industries; forming a solid foundation for further expansion and development.
