CASTILLO DE VILLALBA

Flanges, valves, and other fittings should be to a standard acceptable to the Administration, taking into account the design pressure defined in 5.2.2. Vessel reported a minor leak on the flange directly after valve VL405.

Gas detection equipment acceptable to the administration and suitable for the gases to be carried should be provided in accordance with column F in the table of chapter 19. When crew applied 60% LEL span gas to the sensor, the sensor read 100% LEL. Sensor could not be calibrated and was replaced. 74SOLAS(14)VII/13.1, ICG 93/13.6.1 10C

The company should identify equipment and technical systems the sudden operational failure of which may result in hazardous situations. The safety management system should provide for specific measures aimed at promoting the reliability of such equipment or systems. PSCO observed the sensor for the gas sampling system OGS 30/17 not operating within established procedures/tolerances. Sensor could not be calibrated and read 100% LEL when tested with 60% LEL span gas. Sensor needed to be replaced. Similar issues existed when tested by USCG on 04 DEC 2019 (16 days prior). Recommend an external audit. 74SOLAS(14)IX/3.1, ISM 10.3 50ac

Gas detection equipment acceptable to the administration and suitable for the gases to be carried should be provided in accordance with column “F” in the table of chapter 19. Installed gas detection equipment not functioning as required. PSCO requested test of fixed gas detection, crew applied 60% LEL methane span gas. System consistently read 47% -55% at numerous test point locations.

06105 - Vapor detection equipment should be activated when the vapor concentration reaches the equivalent of 30% of the LEL in air or such other limit as may be approved by the administration in the light of particular cargo containment arrangements. The vessels cargo containment system is of the membrane design. The primary and secondary barrier spaces are foam insulated. The primary barrier space vapor detection alarm is set to alarm at 10 to 30% of methane by volume instead of 30% LEL. Provide attestation that the administration has evaluated the vapor detection installation and verified that it meets the requirements of IGC 13.6.11 74SOLAS 14 VII/3.1 IGC 93/13.6.11 50bc

All ships subject to the code shall be fitted with a stability instrument, capable of verifying compliance with intact damage and stability requirements, approved by the administration. Ships constructed before 1 July 2016 shall comply with this paragraph at the first scheduled renewal survey of the ship after 1 July 2016. Subject vessel experienced renewal survey on 30 April 2018 but has no approved stability instrument onboard. Certificate of Fitness dated 30 APR 2018 does not denote any loading conditions I.A.W. section 6.1,6.2, or 6.3 of COF.
