Modular Construction Savings for Thailand’s Erawan Platform Living Quarters Extension

Specialist Services announces the completion of a 50 Man Offshore Living Quarters (LQ) Module extension now installed on the Erawan platform in the Gulf of Thailand. Designed and manufactured in 8 months, the LQ consists of 4, 2 and 1 Man Cabins laid out over 16 units on two levels.

Living Quarters of this size are normally manufactured as single jetty side modules and shipped for final installation using heavy lift crane barges which has high cost implications.

By ensuring that each unit weighed not more than 10 Tonnes, it was possible to utilise the existing platform crane and thus avoid the high cost and logistical problems of hiring a heavy lift barge. The units were fabricated and pre-assembled to form the complete living quarters in Specialist Services Dubai yard. Before disassembling the entire module services were tested and pre- commissioned to ensure dimensional and functionality of equipment prior to shipping.

All services including electrical, Plumbing, HVAC, Telecommunication and fire and gas systems were all pre-installed during manufacture. Special hook up connections were provided between each unit for disassembly at yard and reassembly at site thus allowing the modules to be quickly connected and commissioned.

The lightweight pre-engineered units considerably reduced the risk over heavy lift applications during offshore installation as they were easily handled and lifted from a supply vessel and maneuvered into position. Offshore installation and hook-up was undertaken by the clients own personnel.

The installation, hook-up and commissioning took just 8 weeks to complete. The existing Living Quarters remained operational during the installation process.
