Maritime New Zealand Continues Rena Wreck Removal Work

Maritime New Zealand Continues Rena Wreck Removal Work

Maritime New Zealand (MNZ) announces that it is continuing the Rena wreck removal work in a co-operation with the US Salvors Resolve.

The marine operations are being conducted after the extended period of bad weather, and according to Braemar Howells Operations Manager Neil Lloyd, Unimar teams were yesterday able to resume pre-rigging containers on the seabed, using a remotely operated underwater vehicle (ROV).

Howells explained: “We were able to pre-rig four containers, getting them ready to haul to the surface. The better weather has also allowed us, under instruction from Rena’s owners and insurers, to begin a visual look with the ROV at the seabed around the aft section of the wreck.

Within the shoreline work Mr. Lloyd said that the work is focusing in particular on plastic beads, which are continuing to impact the Coromandel and as far down as Waihi Beach, where 100 bags of beads and flotsam have been recovered.

“There are 38 beaches on the Coromandel and they all require different recovery methods,” he adds. “The beads aren’t clumped together in large masses, but they are spread over a very wide area.”

The teams are using innovative solutions such as larger vacuum system called a ‘billygoat’ for resolving the problem. The ‘billygoat’ is a vacuum on wheels with brushes which can be driven along the high tide line, sucking beads into a collection bag at the back, and should be able to successfully conduct the removal operations.

EEMUA subsea engineering course: materials selection and corrosion control

This two and a half day training course is recommended for both discipline and project focused engineers from a variety of backgrounds who want to gain an understanding of the fundamental principles for selecting and specifying materials of construction for subsea equipment, and for corrosion control during deployment, commission and operation. The course is based on the EEMUA User Guide to subsea materials selection and corrosion control, EEMUA Publication 194.

It is operated in association with the Society for Underwater Technology (SUT). Permanent employees of EEMUA and SUT member companies are entitled to a 20% discount off the standard course fee.
