An acting record from a recurring Australian Transport Safety Bureau (ATSB) examination has actually outlined the series of occasions of a crammed iron ore service provider’s grounding in a network while leaving Port Hedland, Western Australia in 2022.
The acting record information valid details however includes no evaluation or searchings for.
In the very early hrs of April 9, Liberian- flagged mass service provider Hagen Oldendorff left its berth at Port Hedland, with a harbour pilot onboard. About 50 mins after separation, the ship was taking a trip via the harbour network at 6.8 knots, with one pull attached to its demanding as well as 2 others carefully complying with, when the pilot observed the illumination snuff out on the tail angle signs.
As the ship had actually started to turn to starboard, the pilot purchased port tail, as well as the pull attached to the ship’s demanding to draw the demanding to starboard, to neutralize the swing. Recorded information from the ship’s trip information recorder (VDR) reveals the ship ultimately started to turn to port at a boosting price.
To neutralize this port swing, the pilot guided the pull to draw the demanding to port, however additionally purchased the ship’s tail‘hard to port’ The ship’s master followed this instructions, however after that quized it after regarding 30 secs. Subsequently, the pilot requested for the tail to be placed difficult to starboard rather. The tail angle indication failing indicated the pilot as well as ship’s team were incapable to determine the tail’s placement, or whether it was replying to commands.
While the ship’s price of rely on port decreased hereafter adjustment, it was inadequate to avoid it basing on the side of the dug up network.
“Upon coming into contact with the channel’s edge, the ship’s bow swung away from the side of the channel, back to starboard,” ATSB Chief Commissioner Angus Mitchell stated. “With tugs assisting, the ship was taken out to anchorage for inspection.”
A post-incident evaluation discovered the monitoring electric motor of the bridge’s omni-directional tail angle indication had actually worn out, creating a brief circuit which stumbled the breaker, creating a power interruption in all the tail angle signs offered on the bridge.
An undersea hull evaluation recognized considerable damages, consisting of openings in the ship’s port side as well as lower covering plating, as well as the failing of the transverse bulkhead in between the number 1 as well as 2 port double-bottom water ballast containers, permitting flooding in between them.
Temporary repair services were carried out, as well as on May 18 the ship left on a straight trip to its discharge port inChina After discharging, it continued to the shipyard in Zhoushan, China, for irreversible repair services.
Initial notices of the case offered to the ATSB mentioned that Hagen Oldendorff had actually had a guiding problem as a result of defective tail signs.
“It wasn’t until several months later, in late July, that the ATSB was provided with additional information indicating the ship had grounded in the channel, resulting in substantial hull damage,” Mitchell stated. “After obtaining further information from Pilbara Ports Authority, Port Hedland Pilots, and the tug providers, ATSB investigators travelled to Port Hedland to interview relevant persons and collect evidence.”
As the examination proceeds, it will certainly consist of an evaluation of Port Hedland Pilots’ running treatments, techniques as well as training program, along with evaluation of the conduct of the pilotage as well as the performance of bridge source administration.
It will certainly additionally consist of an evaluation of Pilbara Ports Authority’s plans as well as treatments, as well as an evaluation of towage techniques as well as treatments inPort Hedland Hagen Oldendorff’s guiding equipment plan, controls as well as signs will certainly additionally be evaluated, as well as the ship’s treatments as well as emergency situation preparedness assessed.
The acting record notes Pilbara Ports Authority has, because the case, released an aquatic notification needing that an accordingly certified as well as qualified individual wait in the guiding equipment space throughout a ship’s transportation of the Port Hedland network.
A last record, which will certainly information evaluation as well as searchings for, will certainly be launched at the verdict of the examination.
