    This vessel has Diesel/Electric Propulsion, thus no Main Engines in the conventional sense. There are four main generators to supply power for the Thrusters and all other requirements on board, via a Power Management System.

    The Main Generator room is quite spacious:


    One Main Generator was stripped for major overhaul:


    Propulsion is by two Azimuth Thrusters, driven by A/C Electric motors (3000 kWe each):


    Emergency operation of the Thrusters can be done from the Thruster Room:


    Every valve on board is remotely operated from the ECR or from the Bridge:

    Hardly any manual valves, except the over board valve from the Oily Water Separator, which has to be pad locked against illegal or accidental opening.

    Here is the OWS:

    At the stern is raised structures on either side and a fixed stern gate to protect the working deck during following seas.
    The structures on either sides contains lockers for chemicals, paint, lashing materials and the like:


    Mooring winches are installed on top:


    That completes the external of the vessel.

    The Mezzanine Deck contains two Air diving spreads:


    The FRC in a single point, heave compensated davit:


    Two Taut wire position reference units, one on either side:


    And the Hyperbaric Life Boat for Diver escape under pressure:

    Here being prepared for launch test. (More on that later)

    View of the Working Deck from the Upper deck:

    No wood cladding and no high cargo rails on this type of vessels. This to facilitate constant changing of equipment on deck. No cargo.
    The hand rails are removable to allow equipment to be over hanging the sides, if required.

    The vessel has an actively heave compensated (AHC) offshore crane of 140 t. SWL and able to work down to 2,500 m. water depth:

    This is a complex machine with a lot of hydraulic hoses all over the place:

    Top of Bridge (Monkey Island) contains numerous antennas, the communication domes and the search lights, among others:


    Under the bridge wings on either side is a CCTV camera to look at what is going on over the sides:

    This without having to leave the DP control or maneuver position.

    Below the bridge is a half-deck which contains the Instrument room:


    Externally at this level is the Muster Stations, with boxes containing the Life jackets and Immersion Suites:


    Next level is a storage deck for fenders, dive gas and various equipment:


    Including a Work Boat which is equipped for Air diving away from the mother ship:

    OK, now we get up one level above the bridge, to the Heli-lounge, where passengers can wait in stress less comfort:


    The safety instruction video, as supplied by individual Helicopter companies, is shown on this screen:


    The helideck is of the pre-fabricated type, made from Aluminum with steel support structure:


    The mast is no longer a single "stick", but a fairly elaborate structure. Here seen from the Helideck:


    And here from aft:

    The Bridge is very spacious and fully equipped for world wide operation as a DSV or any other task.

    Fwrd. Controls:


    Aft Controls:


    Port wing Controls:


    Stbd. wing Controls:


    Chart Table:

    Yes, they still carry some paper charts, although Electronic Charts are now the norm.

    This is what she looks like externally while at Sembawang Shipyard, preparing for her next assignment offshore Congo:








    Just to confirm her name and home port:

    I visited a large and sophisticated Dive Support Vessel (DSV) the "Skandi Singapore" at Sembawang Shipyard this last week.
    Built at ST Marine, Singapore in 2011, but of Aker 06 design by STX OSV in Aalesund. Here is vessel specs: http://www.dof.no/Files/System/dof20..._Singapore.pdf

    ​Although primarily a DSV, like most large offshore vessels these days she is also multi-purpose, but not to an extent where she becomes multi-usless.
    Equipped with two work class ROVs and an AHC Offshore crane of 140 tonnes SWL and 2,500 m. of single wire main hook, she is also able to work in deep water, outside reach of the divers.

    Here is first a few pictures taken from the web to show the vessel in full and at sea:




    And at work:

    Stern anchor:


    Hatches open :

    Not much of a view from the cabins in front.

    Notice the offset Bridge? This is because of the cranes are on Stbd. side. (Usually on Port side)
