For the very first time in history, the island of Crete has been connected to the Greek mainland by means of a subsea electricity link. A project commissioned by grid operator ADMIE, and awarded to Hellenic Cables in which Jan De Nul Group installed the 135-km long cable over a very challenging seabed, at up to approximately one kilometer in depth.

Crete had been planning to connect to the Greek mainland, in order to achieve a more reliable, cheaper and environmentally friendly electricity supply.
The Crete-Peloponnese Interconnector is also known as the ‘Interconnection of Records’: two submarine AC cables of about 135 km each as well as 42 km of underground AC cables on land, connect Cretan Chania with Neapoli on the mainland.Tobias Boderé, Project Manager at Jan De Nul Group: “A challenging seabed with rough rocks, cable tensions of 75 tonnes, large water depths of up to 1 km and the installation of an unprecedented length of cable in very challenging adverse weather conditions: all thanks to the tireless efforts of our crew on board the Isaac Newton, we have bridged these 135 km.

Together we successfully delivered the installation of one of the most challenging interconnectors in the world.”

Due to the proximity of the ‘Hellenic Trench’ fault line, the seabed between Crete and the Greek mainland is very rough with steep cliffs. Jan De Nul installed several types of protective material to protect the cable, ensuring its stability and durability. The cable route was optimised and the different types of customised cable protection systems (CPS) were successfully installed.

Damen Shipyards Group has reached a major milestone in the construction of its first fully-electric Reversed Stern Drive tug. The shipbuilder is constructing the RSD-E Tug 2513, named Sparky, for New Zealand’s Ports of Auckland. Recently, Damen Song Cam Shipyard in Vietnam installed the tug’s batteries.

This involved the installation of some 2,240 batteries, totalling 2,784 kWh. With this, Sparky will carry out two or more berthing/unberthing operations with up to 70 tonnes bollard pull on a single charge. Following, it will take just two hours for the tug to recharge to its full capacity.

For redundancy purposes, the batteries are arranged in strings. If one battery in a string were to fail, the others would simply carry on the work.

Ports of Auckland placed the order with Damen in August, 2019. The ports’ intention is to be fully zero emissions by 2040. To achieve this, they needed a zero emissions tug.

Work continues on Sparky and Damen anticipates delivery to be end of this year.

Damen, with its goal of becoming the world’s most sustainable shipbuilder, was keen to take on the challenge. The shipyards group already has extensive experience in the construction of fully electric vessels. Damen has delivered seven fully-electric Ferries 2306 E3 for the City of Copenhagen in Denmark, and a fully-electric Cutter Suction Dredger 650 for an Australian client.

The shipbuilder is also constructing fully electric ferries for Ontario, Canada; a Road Ferry 6819 E3 & Road Ferry 9819 E3, as well as six hybrid Road Ferries 8117 E3 for BC Ferries, British Columbia, Canada. The hybrid vessels are being prepared for future conversion to full electric. Additionally, Damen is constructing nine waterbuses for Blue Amigo to operate in the Netherlands. Three of the vessels will be fully electric, while the remaining hybrid waterbuses will be prepared for future conversion to full electric. Damen has delivered electric vessels with a total of 20 mW of battery power to date.

The E3 certification is Damen’s in-house developed sustainability accreditation for its vessels. It stands for environmentally friendly, efficient in operation and economically viable.

Damen’s strategy is to further develop its existing ship types into electric versions, drawing on proven solutions and combining them with innovation for increased efficiency and sustainability. In addition to the RSD Tug 2513, Damen is also able to electrify its ASD Tug 2813.

DNV has launched the EEXI Calculator – a digital tool to support customers in ensuring their compliance with the upcoming Energy Efficiency Existing Ship Index (EEXI). The regulation is expected to be adopted at this week’s 76th meeting of the Marine Environment Protection Committee (MEPC 76). If so, the regulation will take effect in January 2023..

The EEXI regulation is a medium-term component of the International Maritime Organization’s (IMO) roadmap towards reducing global shipping’s carbon intensity by 40 percent over the next decade, using 2008 as a baseline. The aim of the EEXI is to assess the energy efficiency of existing ships, focusing solely on their design. It determines the standardized CO2 emissions related to a vessel’s installed engine power, transport capacity, speed, and degree of energy efficiency. The regulation will be applicable for all cargo, ro-pax and cruise vessels above 400 GT, depending on their propulsion type and whether they trade internationally. DNV estimates that currently, up to 30,000 vessels need to take action to comply with the upcoming EEXI regulation.

“The EEXI is putting a great deal of pressure on ship owners to take immediate action in order to analyse the energy efficiency of their fleet and make any necessary adjustments to ensure compliance,“ said Knut Ørbeck-Nilssen, CEO of DNV Maritime. “At DNV, we understand the difficulties the industry faces in meeting this regulatory deadline. This is why we have tailored our new EEXI Calculator to meet this need.”

To help customers ensure they are prepared for EEXI compliance, DNV has developed two pathways.

The EEXI Calculator is purpose made for high volume ship segments such as tankers, bulkers and containers. Customers can access this newly launched tool via the Veracity portal under ‘Fleet Status’. The calculator can produce an EEXI calculation and the technical file based on the data uploaded by the customer.

For more complex cases, and when the customer wants to save time and effort, DNV’s advisory experts can work with customers to map out a pathway to compliance, identify the correct parameters for the calculation, and assist in preparing the required documentation.  “These two pathways are designed to help everyone tackle their EEXI challenges in time to reach compliance,” said Fabian Kock, Head of Section Environmental Certification, DNV Maritime. “For companies with a younger fleet, this may not require major adjustments, they can easily access and prepare the required documentation through our EEXI calculator. And for those who need more support, there is the opportunity to tap into DNV’s extensive expertise as they prepare to make more involved decisions around how their vessels can meet the regulatory requirements and secure EEXI compliance when the regulation comes into force.”
