Secretive 88m conversion project unveiled for first time

9 April 2026 • Written by Emily Dawkins

A highly secretive 87.9-metre conversion project has been sighted for the first time on transport leaving the Stahlbau Nord shipyard, a branch of the owner of Lloyd Werft, the Roenner Group, in Bremerhaven, Germany. 

The newly unveiled project was once an offshore supply vessel named ASL Symphony, and, though details and dates remain undisclosed, it is believed that she was purchased by a private owner in Q1 of 2023 who sought to transform her into a capable explorer yacht. In the same year, the vessel's new owner renamed her L Symphony. 

The previously all-red vessel was first delivered in 2015 by Indonesian builder ASL Shipyard as the multi-purpose offshore tug-cum-supply ship, Energy Lindesnes.

Details of her sale and project plans remain highly private, though the new images now reveal her all-white profile, seven extended forward decks and a large helideck. The explorer also appears to feature a large crane, likely as part of her expedition credentials. 

According to BOATPro, the vessel had a volume of 3,921GT before her conversion. Following her works, this is expected to have increased to around 5,000GT. She is equipped with a diesel-electric propulsion system and azimuth thrusters, complemented by Dynamic Positioning 2, offering a top speed of 22 knots. 

The vessel was seen entering the shed to begin her conversion in 2025. She is now expected to undergo further outfitting works in Bremen ahead of her launch.

Lloyd Werft is no stranger to explorer projects, with a portfolio including the 139.7-metre Solaris and the 114.2-metre Luna. The latter of the two joined the brokerage market in June last year and recently received a major €70,000,000 price reduction.
