“Volatile and highly combustible gases that are present during bunkering and the risk of sparks during connection is a dangerous combination. We have now resolved the problem by working with overpressure in the spaces where the cable is housed and connected. This solution will shut out any explosive gases, making the facility safe”

UNIQUE SHORESIDE POWER SOLUTIONS
Volatile and highly combustible gases present during loading and discharge of hazardous products and the risk of sparks during connection is a dangerous combination. This has been resolved by working with overpressure in the quayside spaces where the cable is housed and in onboard spaces where the cable is connected. This solution will shut out any explosive gases, making the whole facility safe.
As part of an innovative plan to provide shoreside power for tankers berthed at the Energy Terminal, the Port of Gothenburg has created a completely new and unique concept that makes the entire system safe, environmentally friendly, and cost-effective. The project – named Green Cable – is being run in association with shipping companies on the island of Donsö, as well as national and European ports, classification societies, local oil companies, and the Swedish Transport Agency. The aim is to set a new global standard for shoreside power for tankers berthed in a hazardous environment.
The greatest challenge is to ensure that tankers that are scheduled to be built and the shoreside power connectors that are fitted adhere to a common standard applied at all ports.
The new standard proposed by the Port of Gothenburg is for all tankers to have their loading crane midships, which would be the optimal solution for lifting the power cable on board.
As a result, the length of the vessel would no longer be an issue and whether she moors starboard or port side is irrelevant. This new standard will also result in substantial cost savings at each berth.
High voltage shore connection for tankers.
MUNICIPAL COMPANY, CITY OF GOTHENBURG
Port of Gothenburg.
It is our vision to be the most competitive port in the world. We aim to provide the best possible preconditions for efficient and sustainable trade via the Port of Gothenburg cargo hub. This means that we must continuously adopt an ambitious approach to work on innovation and develop our operations to meet the needs of today and tomorrow.

FACT FILE
Environmental gain: 1,800 tonnes of carbon dioxide will be saved each year. Green power will be used instead of marine diesel.
The new facility at the Energy Terminal is designed to be a permanent feature in an explosive atmosphere. Safety equipment will be supplied as standard along with the power supply connector.
Safety is guaranteed thanks to a technical solution with overpressure in spaces in which electrical equipment is housed.
The Donsö-based shipping companies Furutank, Donsötank, Tärntank, Ektank and Veritas Tanker, as well as Tarbit Tanker on the island of Tjörn are all
part of the project. They have already ordered vessels on which the new power supply solution has been incorporated. The first pre-prepared vessels were
delivered in 2021, and the first vessels that are completely ready for shoreside power connection delivered in February 2022.Funding: The system will be partially funded with SEK 10.7 million from the government through the Climate Investment Support Programme.
Project implementation: 2022/2023.
Completion: During Q1 2024 the first tanker will be connected to a green shoreside power supply at the Energy Terminal.
The Gothenburg Port Authority is currently investing around SEK 600 million in carbon mitigation measures in a concerted effort to achieve the port’s climate goal by 2030.
SYSTEM DESIGN
Power supply: up to 2 MW per jetty.
Supply Voltage: 6.6 kW.
Grid frequency: 50 Hz.
Cable management system: Shore based cable, handling with onboard crane.
Plug and socket system: Cavotec PC6.
Power intake position: midship in manifolder area,flexible position for starboard or portside handling.
ATEX: design for permanent risks in hazardous area zone 1.
Compartment design: at ship, over pressured by nitrogen to reduce oxygen level below 21 % at shore side, CMS over pressured system by air from safe area.
