Valve billionaire Gabe Newell loves diving so much that he has converted his 305ft superyacht into a support vessel, replacing the onboard spas with a 12-ton crane, decompression chamber, and diving center to accompany his $500 million megayacht on deep-sea adventures


Oceanco superyacht Draak has entered sea trials carrying a fundamentally different identity from the yacht that first left the yard more than a decade ago. At just under 93 meters (about 305 feet) and close to 3,000 gross tons, she began life in 2014 as Equanimity, later sailed as Tranquility, and has now emerged from a comprehensive rebuild as something closer to a utilitarian tool than indulgence. This is not a refreshed charter yacht. It is a reprogrammed asset.


The rebuild sits within Oceanco’s Life Cycle Support framework, a program designed for refits that go well beyond surface-level updates. Last year, Gabe Newell, co-founder of Valve, publicly revealed that he was the owner of Draak, shortly after acquiring Oceanco itself. The scale of this project helps explain why that disclosure mattered. Draak has been re-engineered as a dedicated support vessel for his 111-meter (roughly 365 feet) Leviathan, conceived from the outset to operate as part of a two-ship system rather than as a standalone object. The result is a fleet mindset applied at superyacht scale.


Most of the visible change can be found at the aft. The certified helideck on the upper deck has been removed entirely, not for styling reasons but to create vertical clearance and unlock a far more capable working zone. The main deck aft is now a true tender and workboat deck, fitted with heavy-duty C-davits intended for serious tenders and operational craft rather than decorative toys. Above it, a 12.6-ton jib crane has been added, a capacity well beyond the norm in this size range, allowing Draak to lift heavily equipped tenders, compact research craft, or subsea equipment. At the waterline, the transom has been extended with a larger boarding platform that integrates swim steps and retractable fenders, improving safety and efficiency when operating in swell or recovering divers and gear.

Inside, the original luxury hierarchy has been deliberately reversed. The lower deck beach club and spa have been converted into a dedicated dive center, complete with kitting-up space, storage, and a decompression chamber. The former main-deck saloon now serves as a large crew mess, reflecting the yacht’s operational focus. An upper deck saloon has been transformed into a chef’s lab, designed for experimental cooking, menu development, and intimate events that can support the wider program. New adaptive cabins finished to a high standard allow the yacht to flex between senior crew, technical specialists, and overflow guests as required.

Supporting this new mission required deep engineering work. Ventilation, electrical systems, and core infrastructure were substantially reworked to suit crane operations, tender handling, and dive support. Large parts of the yacht were effectively opened up, with original build drawings used to guide a conversion that is closer to a partial rebuild than a conventional refit.

The logic becomes clear when viewed alongside Leviathan. The mothership is designed as a long-range expedition and live-work platform, with hospitals, labs, dive facilities, and extensive onboard amenities. Draak absorbs the heavy, wet, and technical side of that ambition. Dive safety, decompression, lifting, logistics, and surplus manpower live here, allowing Leviathan to remain quieter and more guest-focused. With Draak’s transformation complete, the vessel will now go through sea trials ahead of her delivery later this year.
