Viking Ship Museum Uses Complete HBK Measurement System

viking ship museum, norway

Introduction

In 2025/2026, a new museum of the Viking Age, which will be an extension of the present Viking Ship Museum, will open on the Bygdøy peninsula in Oslo and, as part of this exciting new project, preparations are already underway to ensure safe handling of the ships and artefacts during the move.

The Viking Ship House within the Museum of Cultural History, which is part of the University of Oslo, houses three Viking era burial ships that were found as part of archaeological finds from Tune, Gokstad (Sandefiord), Oseberg (Tønsberg) and the Borre mound cemetery.

Built as an extension of the present Viking Ship Museum, the new 13,000 m2 building will provide a complete picture of the Viking Age, with the three magnificent ships as the main attraction. Featuring a regulated climate and new support system, the new building will secure the museum’s unique artefacts safely and securely for years to come.

In preparation for the project, the museum’s specialist conservation and collection management staff have been closely collaborating with Statsbygg, the Norwegian Government’s key advisor in construction and property affairs, and external experts to ensure the safe handling of the ships and artefacts, both during the construction process and transition to the new building. However, before this can take place, the ships need to be accurately weighed and this is where HBK was able to step in and help.

Weighing the ships has three main purposes: to determine the total weight; to establish weight distribution; and to monitor changes over time, such as moisture absorption, which can lead to changes in shape. Viewed together with different 3D scanning methods, the ability to monitor the weight distribution will also enable museum staff to understand any potential changes to the ships and effectively remedy them.

Meeting the Need

To move the ships safely and securely, a steel rig will be built around them and a temporary rail system will be laid down. From here, the ships will be lowered down to the new exhibition area. However, before the steel ring can be created, engineers need to collate adequate data. Moving and weighing ships can often be a challenging task as changes in loads or stresses must be minimised or preferably eliminated. To address this, engineers on this project identified many lifting/weighing points and ensured that these points were placed in locations already bearing load. 

In practice, this meant fastening load cells on all vertical supports, and carefully selecting where to place them on the keel support beam, which is the large, shaped beam upon where the ships’ keel rests. Furthermore, to avoid any new stresses, all load cells were placed in pairs.

On the vertical supports, a split bar was clamped to transfer force to the load cells via threaded rods. Angular brackets were also screwed to the side of the keel beam with two 12mm threaded rods connecting the two brackets. Vertical threaded rods again transferred the load to the load cells. When everything was in place, engineers slowly lifted the ship 2.5mm by carefully turning the nuts on these rods in a pre-planned sequence. This was enough to establish weight.

However, when the time came to weigh the bigger Gokstad ship, there were some additional challenges, and this is where HBK was able to help. As weighing points along the keel support beam were being utilised in the moving rig, instead of fastening the brackets that transfer force to the load cells with screws and two approximately placed 12mm rods, engineers needed to use three 24mm hardened steel rods at the lifting point. As these had to be placed with high precision, large holes had to be carefully drilled, whilst causing minimum vibration to the ship.

For this project, Z6 load cells from HBK were installed on various measuring points and connected to a QuantumX MX1615B Strain Gauge Amplifier with catman® AP software.

The MX1615B is part of the QuantumX family that offers compact strain gauge amplifiers that deliver accurate results for both dynamic and static measurements. Suitable for precise and safe data acquisition of strain gauges in full-bridge, half-bridge, and quarter-bridge configuration, as well as strain gauge-based transducers, potentiometers, resistance thermometers (PT100) or normalised voltage (+/-10V), the MX1615B is ideal choice whenever strains, forces and displacements are acquired. Equipped with 16 sensor inputs and arranged in compact housing, typical application areas include static stress tests for FEM models, quasi-dynamic fatigue tests for life analysis, monitoring tasks, material investigations, residual stress analysis, maintenance tasks, as well as for general recording of the load data in the field.  Used with catman® AP software, simple data analysis can be achieved.

Following previous experience with another system whereby hardware had performed considerably better than software, the QuantumX with catman® AP software provided the museum with a complete system which is enabling it to continue to achieve accurate and reliable results.

Conclusion

To cope with the demand required of this large scale and complex project, the versatility of the QuantumX, combined with the ease of use of the catman® AP software has proved itself to be a valuable resource by enabling the museum to prepare for the next stage of its exciting new journey.

The Viking Ship Museum is a national symbol, that houses what is probably one of Norway’s most important contributions to world cultural heritage, so concerns surrounding the move have always been of considerable interest. However, thanks to HBK’s extensive experience in weighing technology and demanding fields, it was able to provide a reliable and integrated solution that is enabling the Viking Ship Museum to achieve the results it needs to set sail onto the next stage of this significant project.
