Penguin International, based in Singapore, is utilizing its experience and technological knowledge to construct crew transfer vessels (CTVs) with green propulsion technology. The company is collaborating with various partners to implement hybrid-electric systems and charging infrastructure, aiming to reduce fuel consumption and emissions in offshore hydrocarbon and renewable energy projects. Penguin's fleet, consisting of crew boats operating in regions like West Africa, Malaysia, Singapore, and the Middle East, will see significant growth in the next few years, with a focus on offshore crew boats with hybrid propulsion. The company continues to build a variety of vessels, including high-speed aluminium boats and larger vessels like ropaxes. There is a growing interest in electric and hybrid propulsion systems, with Penguin considering building more hybrid propulsion vessels. The company is also exploring the possibility of all-electric solutions in collaboration with various operators. In addition to propulsion systems, Penguin is looking into alternative fuels to reduce emissions, although challenges exist due to the maturity and availability of such technologies. Digitalization plays a crucial role in optimizing vessel and fleet operations, particularly for electric and hybrid vessels. Monitoring energy consumption in real-time is essential to achieve a balance between energy efficiency and operational performance. Penguin is leading the construction of Singapore's first all-electric seagoing vessel, leveraging its experience in operating battery-powered passenger ferries. The company is also involved in constructing shore-based charging infrastructure for these vessels. Furthermore, the article mentions UK-based Green Marine's plan to retrofit a crew transfer vessel with hydrogen fuel cells, highlighting the industry's pursuit of innovative and sustainable propulsion solutions.
