In 2010 on an inspection of the EM Control Buoy it was established that two of the three 200 Te tethers that hold the buoy down to the 100 metre deep gravity base were damaged and needed urgently to be repaired in the middle of winter on the precarious Augulus Bank south of South Africa.

Wale Marine were commissioned by PetroSA to design, fabricate and offshore manage an emergency system and procedure for this repair. This solution involved the design and fabrication of specialised bespoke subsea equipment that could be deployed over the stern roller of an anchor handling tug including a sub-sea davit, submersible in line tether buoys, an hydraulic in-line puller.

Wale Marine also designed and fabricated a highly robust HDPE work boat to enable the works to be executed in severe winds and with swell heights s exceeding 5 metres.
