Blom & Grenland Team Up to Provide Subsea Photogrammetry

Blom Maritime AS and Grenland Group's AsIs laser scanning activity have signed a cooperation agreement. The consortium will be the first to provide a total solution of 3D subsea photogrammetry, laser scanning and traditional industry surveying.

"We believe that the two companies can achieve significant synergies by joining forces," says Kristoffer Amdal, Managing Director of Blom Maritime AS. The reasons for the cooperation are obvious. Firstly, the market for qualified workers is at the present very tight, but by cooperating more closely, the companies will be able to utilize their workforce and equipment in a more efficient manner. Secondly, Grenland Group's 'AsIs Laser Scanning' focuses on collecting 3D geometrical data on short range with scanners, and on its data management software (AIMS), while Blom Maritime AS specializes on longer ranges and the use of photogrammetry subsea. The two companies together will be able to serve their clients better with a more complete solution, which can minimize manual fieldwork and overall field engineering man-hours.

"With an operational work force of 40 people, we are certain that the cooperation will give us a strong competitive edge. We are now ready to take on large contracts for verification and control of geometrical data that include scanning and photogrammetry of subsea and topside structures during pre-fabrication, construction and of finished structures," says Inge Byrkjeland, Product Manager in Grenland Group's 'AsIs Laser Scanning', enthusiastically.

The future looks bright for the two companies, as more and more companies realize the power of 3D geometrical data. This was verified at a seminar for 3D geometrical data, held in Stavanger on November 16, where companies like Statoil, ConocoPhillips and Subsea 7 informed the industry about their positive experience with the tools of Blom Maritime and Grenland Group.

The cooperation between the companies has already started. Together, they conducted a scanning of the Karsto Expansion Project for MK Kellogg and Statoil, which involved more than 400 scans, totaling approximately 14 billion points and 100GB of data with a maximum global deviation of 5mm.

Blom Maritime AS is part of the Blom Group, and offers collecting of 3D geometrical data by using photogrammetry and scanning. The company also provides hydrographical and dimensional control services along with its own Blom Positioning Monitoring System.

Grenland Group's AsIs laser scanning activity provides laser scanning and data modelling services throughout the lifecycle of production facilities. This includes online 3D geometrical data storage and management of any facilities. The database is kept updated and distributed to the client.
