Client: Etheridge Shire Council, Queensland Scope of Work Charleston Dam provides water to the townships of Forsayth and Georgetown in Queensland. The dam is located approximately 400km southwest of Cairns (1,800km north-west of Brisbane). North Marine crew and commercial divers install water intake pipes, an electrical pump, four mooring systems and two pontoons to house the raw-water intake infrastructure, for the Charleston Dam. Additionally, water pipes are poly welded and groundcover pipe/electrical cable areas are trenched and filled over (approx 100meters) from the reservoir to the dam.

Salvage of the Iconic Underwater Observatory at Green Island

Green Island, Queensland

The 1954 Green Island Underwater Observatory is Salvaged The experienced commercial dive division of North Marine successfully executed the salvage and removal of the submerged structure, located at Green Island out of Cairns. A Key Piece of Queensland Tourism History It is with a sad heart and happy memories that North Marine undertook the massive task of deconstructing and salvaging the iconic 1954 Underwater Observatory at Green Island. About the Green Island Underwater Observatory The underwater observatory at Green Island was the brainchild of Vince Vlassoff, a 37-year-old Australian born Engineer, and Lloyd Grigg after they met on a crocodile safari cruise operated by Vlassoff. Before snorkelling or scuba diving had become mainstream activities, this pioneering piece of architecture truly was a revolution in reef tourism, which up until this point had largely been occasional ferry trips taking people to offshore islands for a day trip. Never before had the general visitor had access to freely view the Great Barrier Reef beneath the surface. The entrepreneurial pair imagined an underwater theatre, unlike anything ever constructed of its kind before. They envisioned a place where the public could venture beneath the waves to a chamber of windows, whereby they could witness the marvellous fish, coral and aquatic life to be seen. Construction of the chamber began in 1951 and took twelve months from planning to final submersion – an incredible time frame considering the challenge of the task and all the unknown factors. For nearly 60 years the underwater observatory delighted visitors and provided a means of viewing the incredible underwater world.   Visit these pages for more information on North Marine services Marine Services Commercial Diving Services
