ym-efficiency-1-768x491.jpgAccording to a report from the Australian Maritime Safety Authority (AMSA), the initial subsea search identified the containers and what appears to be associated debris in late July.

The search was conducted over a period of six days by the Port of Newcastle surveying vessel JT Gowlland on behalf of the YM Efficiency’s insurer, Aus Ship, and owner, Yang Ming.

The parties have agreed to continue survey operations to locate as many as 42 containers which are still missing. AMSA said that, once the remaining containers are located, it will be able to assess the risk they present to trawling operations in the area.

YM Efficiency lost 81 containers some 30 kilometres off the coast of New South Wales, while another 62 were damaged in the incident. The 4,250 TEU vessel was on its way from Kaohsiung, Taiwan to Port Botany in Australia, when it was hit by severe weather conditions.

According to an earlier report by the Australian Transport Safety Bureau (ATSB), while the containership was in a position about 16 nautical miles east-south-east of Newcastle, it experienced a period of quick, heavy rolling for about 60 to 90 seconds prior to losing the boxes. The rolling was estimated by the ship’s master as having reached angles of up to 30º to port and starboard.

Product Description

Mooring winches secure the shipboard end of mooring lines, provide for adjustment of the mooring line length and OUCO-Marine-Vessel-Hydraulic-Anchor-Horizontal-Mooring.pngcompensate for changes in draft and tide. General requirements for shipboard mooring winches are dealt within ISO Standards 3730 and 7825.

Winches can be categorised by their control type (automatic or manual tensioning), drive type (steam, hydraulic or electric), by the number of drums associated with each drive, by the type of drums (split, undivided) and by their brake type and brake application (band, disc, mechanical screw, spring applied).

Product Feature

Automatic tension mooring winch, self-tension winch – Winches designed to heave-in automatically whenever the line tension falls below a certain pre-set value. Likewise, they pay out if the line tension exceeds a pre-set value. The use of the self-tension winches is not recommended except for mooring deployed at 90° to the ship axis.

Manual tension mooring winch  – Manual winch always requires a person to handle the controls for heaving or rendering.

Non-split drum mooring winch  – The undivided drum winches are commonly found on smaller ships. It is often difficult to spool and stow the wire on such a drum satisfactorily; when wires are handled directly off the drum, the final turns of the outer layer when under tension tend to bite into the lower layer. This could result in possible wire damage and difficulties when releasing the line. To reduce this problem, the winch with non-split drum should be placed at a sufficient distance from the fairlead to ensure that the wire can be properly spooled.

Split drum mooring winch  – A winch with a drum divided by a notched flange into a tension section and a line storage section.
