Our history goes back to 1993 when RIISE Underwater Engineering (RUE) was established.

The company acquired the Diving Support Vessel, Risøy and has performed a variety of diving work along the Norwegian coastline. In 2010, RUE became a part of the Fugro group and gained good experience from inshore and offshore activities both in Europe and in Africa. The transfer of Fugro RUE in 2013, was the birth of SubseaPartner supported by Cinclus Equity Partner and Cinclus IV as the major shareholder.

In the early years of SubseaPartner DSV Risøy and inshore dive operations was the company’s primary activity. The project team with DSV Risøy performed extremely demanding diving work on the Statpipe shore approach at Kalstø, west of Haugesund.

In 2016 SubseaPartner we entered the offshore diving segment in the North Sea. From this point the Norwegian Continental Shelf and UK Continental Shelf became the primary market for SubseaPartner. The investment in LDC Trust and LDC Venturer manifested this new direction.

From 2022 our strategy has been firm to offer subsea services to customers in the floating assets market offshore, near-shore and in-shore on NSC and UKCS. In 2024 the company invested in two new state-of-the-art vessel-based diving systems

Our process for due diligence is based on “OECD Due Diligence Guidance for responsible business conduct”.

ACTIVITY 1: Overall risk evaluation

We are evaluating our suppliers on management level to evaluate whether we see a risk of negative impacts to basic human rights and decent working conditions through supplier audits.
We are evaluating the risks based on criteria’s such as country of operations, industry and yearly procurement spend. If we do not see any risk with the supplier, the evaluation will stop at this point in the process.

ACTIVITY 2: Deep risk evaluation

If we do see a risk in Activity 1, we need to do a more detailed risk evaluation in Activity 2. We will evaluate the findings in Activity 1 against SubseaPartner’s knowledge about the supplier. If this is not sufficient, information and documentation will be collected from the supplier to make a full evaluation. If we then don’t see any risk with the supplier, the evaluation will stop at this point in the process. If the supplier is not able to satisfy the evaluation requirements of SubseaPartner then we will proceed to the next activity in the process.

ACTIVITY 3: Establish action plan

ACTIVITY 4:  Deliver on actions

In these activities we will use the findings from Activity 2 to create and implement an action plan to mitigate the risks identified. If necessary, our Partners or Collaborators will be involved in this step.

ACTIVITY 5: Lessons learned

In this step we evaluate the learnings from the process and the action taken. In this step we will confirm that the actions have resolved the identified risks and the negative impact has been reduced. Lessons learned in this step will be implemented to future processes.
