17 tons weight removal resulted draft reduction of 28 cms.

22nd March 2022 – Haul-out day.

Cariad’s extreme draft and knife-like keel highlighted PSS as the only yard in the region capable of hauling out Cariad.  Circumstances left no room for mistakes.

 

Based on previous experience we took no chances.

  • Waited 2 months for a suitable high tide.
  • 9m on Koh Terutau and 3.4m Koh Koi Noi depending on how you measure the tide at PSS, which is tricky.
  • Over a two-month period we reduced draft by 28 cms by offloading weights.
  • Booked a 60-ton in case we needed to lift the bow further onto the trolley at the last minute. (In hindsight the crane saved the day for us)
  • Welded steel supports internally under anchor winch in case of heavy pull by cranes (was needed)
  • We completely rebuilt the trolley plus 4 big steel adjustable uprights.
  • Installed additional 4 x 2-ton chain blocks from trolley to Caried bulwarks as double back up.
  • Rebuilt and extended railway lines.
  • Brand new winch wire.
  • Brought in specialist haul-out crew from Songkhla.
  • Cariad team supplied their 10 best people.
  • Chartered the brick barge tug to turn Cariad and assist it onto the trolley.
  • A total of 27 people were employed in the haul-out operation.
  • Khun Uun, the shipyard manager, controlled the whole operation.

Lifting bow to ensure trolley could run underneath without jamming.

First look…..Short keel sitting on relatively short trolley.
