Singaporean company GL Engineering & Construction (GL E&C) has launched a new concrete floating dry dock, the US$12m Peleke Nui (‘Big Fred’ in Hawaiian), in Batam, Indonesia. It has been built by a local subcontractor.
The buyer is Marisco Limited, based on the island of O’ahu, Hawaii. Marisco provides construction, maintenance and repair of ships and naval craft, and serves governmental, military, commercial marine and industrial sectors from its base in Barbers Point Harbor on the west coast of the island.
The dry dock is currently on its way to Hawaii on a heavy lift ship and is expected to arrive at its destination by the end of May 2017. Upon its arrival, it will be the largest in the fleet of dry docks that Marisco owns.
Alfred Anawati, president and founder of Marisco, said, “The new concrete floating dry dock will be the biggest yet for the state of Hawaii and will serve Marisco’s expanding international businesses with possible future projects for commercial clients in Asia and worldwide. Given the high demand for ship repair work, we have already received orders for use of the dry dock even while it was still under construction.”
Designed for a durability of 200 years, concrete dry docks are far more stable in operation and offer better weather resistance due to their heavy weight compared with steel ones, which typically have a 20-year design life.
Made of high-strength Grade 85 concrete, the completed dry dock has a concrete pontoon and steel wing wall. The unit is 15m high, 138m long and 46m wide with clear working space of 36m inside the wing walls. The dock will lift ships up to 9,500 metric tons and can repair two to three ships concurrently depending on their size. - May 2017
