3.4.5 HOP Heavy Phase Discharge. The Contractor shall remove and dispose of the 1 ½” HOP heavy phase discharge line from the discharge union located on the HOP to approximately 1 foot prior to the existing tee located at approximately frame 147 (shown in Figure 5). Install a Lokring pipe cap as shown on Coast Guard Drawing 901 WMEC 245-019 or 905 WMEC 245-011, as class applicable.

3.4.6 HOP Hydraulic Oil Supply and Cross Connect Piping. The Contractor shall remove and dispose of the HOP hydraulic oil supply line and the HOP/Hydraulic Oil Transfer Pump (HOTP) cross-connect piping. The Contractor shall reconnect the HOTP suction line to the suction side of the hydraulic oil discharge manifold.

3.4.6.1 The Contractor shall disconnect, remove and dispose of the HOP suction line from the inlet flange on the HOP to the 1 ½” flange (point “f”) located on the suction side of the hydraulic oil discharge manifold as shown on Coast Guard Drawing 901 WMEC 245-019 or 905 WMEC 245-011, as class applicable.
