Karamine completes refit of semi-submersible support ship

The refit of 146m (479ft) semi-submersible support yacht, OK has been completed by Turkish-based Karmarine Shipyard. Built back in 1982 by Oshima Shipbuilding and originally named AS Super Servant 3, the vessel is now back on the water as an expedition motor yacht.

The vessel has a beam of 32m and exterior design styled by Bozca Design. The aft deck is the biggest feature on the vessel sized at 3,300sqm. In her previous life, OK was used as a ship to transport yachts, hence the large open flat deck.

Post-refit Karmarine can now provide storage room for 70 different toys, including a 46m sailing yacht, multiple tenders, buggies, amphibious vehicles and a sea plane. However, the deck can also be fully submerged. This ability to submerge allows OK to carry a wide range of tenders and toys removing them directly from the water.

Karmarine improved the strength of the superstructure so OK can handle both stern and side loading.

Away from the deck OK also features a glass-wrapped sun deck jacuzzi, an outdoor cinema, a tennis court and a botanic garden. She also features four large aquariums, a car ramp, a 40t crane and a vertical wind turbine.

OK can accommodate up to 20 guests across its staterooms, each with a panoramic 360-degree view.
