Kongsberg Maritime has signed an agreement with Island Offshore to provide turnkey hybrid battery solutions for the company’s three UT 776 CD-design Platform Supply Vessels.
Two ships, Island Crusader and Island Contender, previously used a combination of Bergen LNG and Bergen Diesel engines, while Island Commander used four diesel engines.
Converting all three ships to hybrid vessels demonstrates the company’s commitment to environmental responsibility.
It will also increase operational efficiency and reduce maintenance requirements significantly, resulting in cost savings for the company.
Previously, PSVs were used for multiple engines to achieve redundancy, in turn, affecting fuel efficiency, equipment health and emissions.
However, the use of conventional liquefied natural gas (LNG) or diesel engines in conjunction with the Kongsberg SAVe Energy battery system, which is certified by DNV GL, is said to bring instant benefits.
The battery enables fewer engines to run, increasing efficiency and the load on the other engines while providing instant power on demand.
By turning the ship into a bus-tie operation, it will also reduce fuel consumption and operating costs.
The solution chosen by Island Offshore will run through the power supply from the energy storage system (ESS) to the manual conversion of the main switchboard, enabling the operator to balance the generator runtime and have a 600kW double shore connection.
The Kongsberg Maritime 8m / 26ft ESS 896kWh deckhouse will include a standard liquid-cooled container solution, as well as air-cooled SAVe Energy batteries.
The delivery will also include modifications to the main switchboard and the K-Power EMS energy management system for each vessel, along with the upgrade of Acon automation and alarm systems.
Island Offshore Management MD Tommy Walaunet said: “We are pleased to be working with Kongsberg Maritime on this endeavour as a leading supplier and strategic partner to our business.
“By making this investment despite challenging market conditions, we underline our commitment to continue reducing our vessels’ environmental footprints and our strong belief in a sustainable future for our business.”
