AEC was engaged by Woodside Energy Ltd (WEL) to develop a procedure for the replacement of the 5.5” diameter x 84m long reconnection wire assembly located within the Riser Turret Mooring (RTM) of the Okha FPSO, which was approaching the end of its working life. The rope had previously been replaced using a subsea diving spread, however, an alternative was sought to minimise risks, mobilisation time and expenditure. The weight of the rope assembly including fittings was 6.7t.
