INTRODUCTION
1.1
Project Background Jangkrik Field (JKK) is a gas discovery made in March 2009. It is located about 70 km from the coast, in the MuaraBakau permit area, Makassar Strait, offshore Kalimantan, at a water depth ranging from 250 to 500 m. Eni, through its Indonesian subsidiary, operates the MuaraBakau PSC with a 55% interest, in joint venture with GDF Suez, holding the remaining 45% interest. The selected concept is based on a subsea development with seven wells, full treatment facilities on a spread moored FPU and export line to shore at Sapi landfall. Jangkrik North East (JNE), located at about 25 km NNE from JKK Main, is a recent gas discovery, made in July 2011. The selected concept together with the tie in of Jangkrik North East to the FPU has been studied in detail during the basic engineering phase completed in April 2012. The concept studied in this FEED foresees: • • • •
7 Subsea Wells for JKK tied back to the FPU; 4 Subsea Wells for JNE, tied back to the FPU (as option) a Barge Shaped FPU, performing Full Offshore Process; Export treated gas and condensate to onshore near Sapi existing plant.
Final destination of Jangkrik gas is Bontang LNG Plant and local market. Final destination of Jangkrik condensate is Senipah Plant. 1.2
Scope of the document This document defines preliminary cooling load and ventilation requirements for sizing HVAC equipment for Topside Local Equipment Room (LER), warehouse, workshop and laboratory at JANGKRIK FPU. The preliminary cooling load is calculated in accordance with ASHRAE FUNDAMENTALS / ASHRAE GRP 158 using excel form. The detail HVAC cooling load nee to be performed during detail engineering.
