Mark Heine, CEO: “We experience high client demand for our solutions for the energy transition, climate change adaptation and sustainable infrastructure. As energy security is now firmly on the agenda, traditional energy activities are also growing stronger than anticipated. The positive market sentiment is demonstrated by recent awards. These include site investigations for bp’s offshore wind farms Morgan and Mona in the Irish Sea and artificial islands in Hong Kong’s Central Waters, as well as a coastal resilience survey along India’s Andhra Pradesh coast.

The current market outlook supports our Path to Profitable Growth strategy. It is encouraging that we improved our margin and cash flow in a seasonally weak quarter. We remain focused on disciplined tendering and mitigating inflationary pressures.

As communicated earlier, we are suspending our limited operations in Russia as a consequence of the tragic war in Ukraine. The war particularly affects our marine crew from Ukraine and Russia. We have immediately set up teams tasked with providing tangible support for our Ukrainian colleagues and their families. I am very impressed by how everyone involved has been handling this extremely difficult situation and in the meantime, we secured sufficient staff to ensure ongoing operation of our vessels.”
