SEAWIN SAPPHIRE - AGROUND OFF MELKBOSSTRAND
In attempting to get a towline to the Weskus 1, which
lost power in Table Bay, both vessels ended up on the beach between
Melkbosstrand and Bloubergstrand in Cape Town, South Africa, in August
2008.
Both were fishing vessels, the Weskus being of Wooden
construction, and the Seawin Sapphire being a 22m Steel vessel, of
Lightship Displacement 155 tonnes, as shown in the pictures.
Due to the likelyhood of having to travserse a reef
in towing her off, it was decided to drag her up the beach to the
carpark and then lift her onto a heavylift trailer and road transport
her back to the harbour.
Triton were initially contracted by SMIT and then
later by ALE Heavy Lift in assisting on the Naval Architectural side,
and also for the design and construction of the +120tonne towing bracket,
which was slotted through the base of the bulkbous bow, to tie in
with the exisiting double bottom and keel structure.
As it so happened the highest drag force applied
was 155 tonnes, when cresting the bank of the beach, with an average
drag force in the order of 70 to 80 tonnes.
The entire excersize was carried out successfully
between the 18 and 26 August.
