InterMoor, an Acteon company, recently completed a top chain replacement project the Armada Perkasa FPSO offshore Nigeria.
The FPSO is spread-moored in shallow water in the Okoro field. The Okoro field lies at a water depth of 14 meters in block OML 112, which is situated about 12km off the shore of Nigeria. The field was discovered in 1973 by Japan Petroleum.
The 211.2 meters long Armada Perkasa is located 1km south of the field at 13 meters of water and is connected to the Okoro wellhead platform through flowlines and risers.
InterMoor’s crew completed top chain replacement of all ten mooring lines of the FPSO and uncrossing of two mooring lines.
Top chains had worn out due to chafing at high tensions. InterMoor provided engineering/ procedure development, procurement, and offshore implementation. The job was completed safely and with no production shutdown required.
