'Taking a Deeper Look at the Offshore Industry'
Brian Raine has prepared a paper on the Malampaya Depletion Compression Platform which
has been selected for presentation during OTC 2016. The paper describes the design and
installation of the platform inspite of the unusual ground conditions.
Arup - Malampaya
The Depletion Compression Platform (DCP) was concieved by Shell Philippines Exploration
B.V (SPEX) to provide additional gas compression to account for the future expected decrease
in well pressure from Malampaya field. The Malampaya project is very important to the
ongoing prosperity of the Philippines, with the exported gas feeding three power stations which
have a combined output providing up to 45% of the power needs of Luzon, the largest and
most populous island in the Philippines.
The DCP consists of a sealed barge structure which is rigidly connected to four cylindrical
legs, each of which is supported on individiual strut-linked hexagonal pad footings. The DCP
arrangement used cylindrical rather than truss legs and the base comprised a series of linked
pad footings rather then a skirted baseplate. The leg configuration was selected in an attepmt to
simplify the leg fabrication; whilst the use of pad footings was a result of the site geotechnial
conditions.
Installation of the DCP commenced after the arrival at the Malampaya site following the wet
tow from Subic Bay. On the morning of 12 February 2015 base lowering commenced with
touchdown occurring on the seabed some 26 hours later. Barge raising commenced
immediately thereafter with the barge clearing the water around midday on 13 February 2015.
Barge raising to the required elevation was completed in the early hours of 14 February 2015,
a total of less than 2 days.
The presentation will describe the unusual ground conditions, innovative geotechnical and
structural design undertaken, offshore work performed during both seabed preperation and
DCP installation to ensure a successful outcome to the project.
