Ambassador Cruise Line plans to equip all three ships in its fleet with shore-power connections under a retrofit programme running through to autumn 2028.
The company has signed a contract with marine engineering specialist EnerMoves SRL for a shore-power system aboard Renaissance. Work on that project has begun, with final installation and commissioning scheduled during the ship’s planned dry dock in October and November 2027.
Similar equipment is planned for Ambience during a dry dock in November and December 2027, followed by Ambition in autumn 2028. Ambassador says the programme demonstrates how existing cruise ships can be upgraded to meet modern environmental standards without requiring replacement by newly built vessels.
Renaissance will receive the first installation
Renaissance is the first of Ambassador’s three ships covered by the programme. The company has contracted EnerMoves to design and install a system that will allow the vessel to connect to an electricity supply from the shore while alongside at a suitably equipped port.
Preparatory work is already under way. The main installation and commissioning work is expected to be completed during Renaissance’s scheduled dry dock in October and November 2027.
Renaissance joined the Ambassador fleet after the British company merged with French operator Compagnie Française de Croisières in January 2025. The vessel primarily serves the French market during summer before operating Caribbean fly-cruises for British, French and Dutch passengers during winter.
Ambassador has not published the cost of the Renaissance contract or the expected electrical capacity of the completed system.
Ambience and Ambition installations are planned
Ambassador intends to extend the technology to its two UK-focused ships after work aboard Renaissance.
A second contract with EnerMoves is planned for Ambience, with installation expected during the ship’s scheduled dry dock in November and December 2027. Ambition is then due to receive a shore-power connection in autumn 2028.
The wording is significant: the Renaissance agreement has been signed, while the installations aboard Ambience and Ambition are currently described as planned. Ambassador has nevertheless presented the work as a fleet-wide environmental programme covering all three vessels.
Ambience and Ambition operate Ambassador’s adult-only, no-fly cruises from regional UK ports. The retrofit could therefore allow the ships to use shore electricity at an increasing number of British and European ports as compatible infrastructure becomes available.
What is cruise-ship shore power?
Cruise ships continue to require electricity while they are in port. Power is needed for lighting, ventilation, kitchens, refrigeration, water systems and the many hotel services used by passengers and crew.
Without a shore connection, a ship normally generates that electricity using machinery aboard the vessel. Shore power — sometimes called cold ironing or onshore power supply — allows a compatible ship to connect to a port’s electrical grid instead.
This can reduce local air emissions and engine noise while the vessel is alongside. The overall climate benefit depends partly on how the shore electricity is generated, while the connection can only be used where both the ship and its berth have compatible equipment.
A shore-power installation does not mean that a cruise ship can operate without its engines at sea. The technology is specifically intended to supply the vessel’s electrical needs during port calls.
Retrofitting older ships presents technical challenges
Adding shore power to an existing vessel is more complex than installing the equipment during construction. Engineers must integrate new electrical hardware with the ship’s established power-management and safety systems.
The shipboard equipment must safely synchronise with different shoreside supplies and manage the transfer of the vessel’s electrical load. Cabling, connection equipment, control systems and space aboard the ship all form part of the engineering work.
Ambassador says EnerMoves was selected for its approach to managing the interface between onboard systems and shore-based electricity supplies. Scheduled dry docks provide the opportunity to complete major physical installation work while the ships are already out of passenger service.
Part of a wider environmental programme
Ambassador describes the shore-power project as the latest stage in its efforts to improve the environmental performance of its existing fleet.
The company says its ships already have advanced food-waste and sewage-treatment systems. They also use selective catalytic reduction technology intended to meet International Maritime Organization Tier III requirements for nitrogen-oxide emissions when operating in the relevant regulated areas.
Installing shore connections will address a different part of the vessels’ environmental footprint by reducing the need to generate all of their electricity aboard while berthed at compatible ports.
The benefits will depend on where the vessels call. Shore-power infrastructure is expanding, but it is not yet available at every cruise terminal, and a ship cannot connect merely because it has been equipped to do so.
Why the announcement matters for UK cruising
Ambassador markets itself around no-fly cruises from regional UK ports, making the planned work particularly relevant to the development of British port infrastructure.
Ports including Southampton are already investing in shore-power capability, while other UK cruise ports are examining or developing similar systems. Equipping the ships increases the number of occasions on which Ambassador may be able to use that infrastructure as compatible berths become available.
The programme also shows that shore-power adoption is not limited to the newest cruise ships. Ambience, Ambition and Renaissance all began their careers with other operators and are being retained through refurbishment and technical upgrades.
Completion across all three ships would give Ambassador a fully shore-power-capable fleet by the end of the planned Ambition installation in autumn 2028. That timetable remains subject to the individual contracts, dry-dock schedules, engineering work and commissioning being completed as intended.
Frequently asked questions
Which Ambassador ship will receive shore power first?
Renaissance is first. Ambassador has signed a contract with EnerMoves, with final installation and commissioning planned during the ship’s October–November 2027 dry dock.
When will Ambience receive shore power?
A similar installation is planned for Ambience during its scheduled dry dock in November and December 2027. A second EnerMoves contract is planned but was not described as signed when the programme was announced.
When will Ambition receive shore power?
Ambassador plans to install the system aboard Ambition in autumn 2028.
Will Ambassador ships be able to use shore power at every port?
No. The vessels will only be able to connect at berths with compatible shore-power infrastructure and where operational arrangements permit its use.
Does shore power eliminate all emissions from a ship in port?
It can substantially reduce the need to run onboard machinery for electricity while alongside, cutting local exhaust emissions and noise. The overall environmental benefit also depends on the source of the shoreside electricity and the ship’s remaining operational requirements.
Has Ambassador signed contracts for all three ships?
The company has confirmed a signed EnerMoves contract for Renaissance. A second contract is planned for Ambience, while an installation aboard Ambition is planned for autumn 2028.
