Damage assessment:
Pieces of granite rock embedded in the hull cracks.
The hull was dented for a length of about 300-feet and, in several places, there were small cracks a few inches thick.
On the starboard side of the keel plate was a 21.34 (70-feet) fracture between frames 175 and 206 and a 5.49 metres (18-feet) fracture between frames 172 and 178.
Five smaller fractures, 0.41 metres – 1.62 metres (16 – 24 feet) were found forward of the major fractures on the keel plate between frames 207 and 220.
Two areas of damage were found on the starboard side to the bottom strakes ‘B’ (frames 210 – 236), ‘C’ (frames 141 – 221) and ‘D’ (frames 178 – 203).
The bottom of the shell plating, together with the internal structure, was upset, deformed and damaged.
One area of damage was found on the portside with ‘D’ strake at frames 178 – 193 being upset approximately 7 – 1 centimetres (3 – 4 inches) together with the attendant internal structural framing.
The port bilge keel was heavily deformed over approximately 6.1 metres (20-feet between frames 151 and 163.
There was evidence of paint scrapes due to contact starting at the bulbous bow and extending aft over a length of 400 feet aft and covering a width of 80 feet over the keel and either side of it and consisted of indents – some up to 240 feet in length and 14 inches deep – gouges and fractures. Paint scrapes and minor indents were noted on both sides as high as about two-feet above the keel plates (vertical measurement). The paint scrapes gradually transitioned into shallow upsets in the plate and then into large fractures on the flat keel.
Twenty inner bottom tanks – mostly empty or carrying fresh water – had been damaged to some extent although one, No 10, an empty fuel tank, was the only tank to have leaked a small amount of oil residue at the time. The fractures in way of some of the indents were from 10 to 70 feet long and a 32 foot length of the port bilge keel had been severely damaged during the grounding.
Internally some of the transverse floors and longitudinals (both structurally important upright ‘walls’ the comprise a ships cellular double bottom) were damaged by bucking and only in No 3 cargo hold was the deck bulging inboard, possible as a result of the flooding.
The fractures and damage ended abruptly just forward of amidships at approximately frame 172.
Rumours that the keel had been bent proved to be unfounded.
A thorough internal examination was undertaken and, fortunately, there was no damage to the stern, the propellers or the steering equipment.
