SUBSEA TECHNOLOGY
SUSTAINABLE ELECTRIC POWER While rechargeable lithium-ion batteries have become commonplace in most consumers’ daily lives, it’s a relatively new technology for subsea operations. “These products are a big step forward for the subsea industry and an important topic for us, particularly in terms of the way they improve the industry’s sustainability,” Marx says. “First, because we’re replacing primary batteries with rechargeable batteries, and secondly, because hydraulic systems are being replaced by battery-electric systems which have a design life of 25 years, so they’re very robust and clients don’t have to replace them frequently, this makes them sustainable.” At the end of one of SubCtech’s
battery lives, customers can simply return the batteries to the company, which then forwards them to specialist partners for recycling. Although they are also fully recyclable, the titanium pressure hulls housing SubCtech’s batteries have an

endless design life and are reusable. The recycling process must follow
strict legal guidelines to ensure full transparency. “German law requires that every item we recycle be documented so that the fl ow back to to raw material is also documented,” says Johannsen. Concluding, Marx explains how the
company’s best assets are driving it forward: “We’ve learned over the
years that even as a medium-sized company, we’re able to move the world a little bit. We have the best products, a great reputation and a high-quality team. In my 30 years in the industry, that’s been the recipe for success.”
