We acknowledge that environmental conservation is crucial for our survival not only as a shipping company but also as individuals. In this context, we have embarked on an extensive ecological investment program mainly focused on the early adoption of Ballast Water Treatment Systems (BWTS) and voluntary installation of Sulphur Oxides (SOx) Exhaust Gas Cleaning Systems (EGCS), known as scrubbers in half of our fleet, mainly on the higher DWT vessels. Our Green Investments, as of December 31st 2020, amounted to USD 67.2 million. Currently, we operate 20 vessels fitted with EGCS and 31 vessels with BWTS.
We have also launched an extensive ongoing fleet renewal program, selling our older and less efficient vessels and investing in more modern and efficient second-hand vessels and state-of-the-art Japanese built newbuilding vessels. Our orderbook as of today is comprised of five Kamsarmax and three Post-Panamax vessels scheduled to be delivered between 2022 and 2024. All our newbuild vessels on order are Japanese and designed with energy and power-saving features to meet the latest GHG emissions ‘EEDI, Phase 3’ requirements and comply with IMO’s NOx Tier III regulations.
