8.17.9 Is there a competent person in charge of ballast control and stability calculations?
Where applicable, is person suitably qualified under STCW95? For MODUs, all personnel involved in ballast control operations should be trained and certified in line with IMO Resolution A.891(21), includes OIM, Barge Supervisor and Ballast Control Operator.
8.17.10 Can the Ballast Control Operators (BCO's) demonstrate adequate knowledge of the vessel/unit's ballast system, the control of free surface effects and the consequences of inadvertent ballast shift?
Demonstrated via induction and vessel specific training records. If semi-submersible, to be capable of taking unit to survival draft if required. BCO's should know the operating inclination limits of the ballast control system, this should be stated in onboard documentation.
8.17.11 Can the vessel/unit's stability be calculated without extensive calculations?
© Copyright OCIMF 2011. All rights reserved. 92 8.17.12 Is the stress and stability information included with the plan for current operations; have stability and where applicable, stress calculations been performed for the current operation and do the BCO's understand any limitations?
Inspectors should determine that prior to specific operations involving the transfer of weights; calculations have been made for stress and stability conditions for the start, interim and completion of operations.
Regular monitoring of stress and stability should be taking place throughout the operation to ensure that the conditions have been maintained within design limits.
8.17.13 Is there an inclinometer located near the ballast control panel?
8.17.14 If fitted, are draft gauges operating correctly?
Procedure for calibration and cross reference to visual and loading computer values.
8.17.15 Are draft marks on vessel/unit clearly visible?
8.17.16 Is there a system for managing manual inputs into the stability programme?
System of cross checking should be in place to assure accurate weights and CoG of materials placed subsea or recovered from seabed, are manually input to keep stability model accurate. Inspector to verify that sample inventories of variable weights appear reasonable and accurate.
8.17.17 Is there a system for recording changes to the vessel/unit's lightweight condition?
Documented procedure with record sheets showing additions/deletions since last inclining experiment conducted.
8.17.18 Are the ballast and bilge systems covered by an FME(C)A?
8.17.19 Is there a system for controlling the override of bilge and ballast system alarms?
To be covered in procedures and documented.
8.17.20 Is access to the ballast control panel restricted?
System to be in place to prevent unauthorised operation of bilge and ballast system.
8.17.21 Is the ballast control position attended continuously during sub-sea operations?
Ballast station to be manned continuously to ensure prompt action can be taken when required.
8.17.22 Are all watertight doors, hatches and other openings in good order?
Seals, locking devices and remote indicators should be in good order and fully functional.
8.17.23 Is there a system for monitoring crane status during use and when stowed?
Crane should be regularly checked to see if slewing or rocking motions are controlled in a seaway; tension monitoring equipment should be operational.
8.17.24 If Column Stabilised unit are there at least two ballast pumps available to pump out each ballast tank?
If column stabilised, the pumps should be physically separated so that loss or damage to one pump will not adversely affect the other pump. To be confirmed by FME(C)A.
8.17.25 Are pumproom emergency bilge suction valves clearly marked, fitted with a position indicator and capable of remote operation?
8.17.26 Is the vessel/unit equipped with service cranes covering all anticipated operations?
Located to minimise blind sectors.
8.17.27 Are all cement silos and associated valves, pumps, vents and air supplies fully tested and in good order?
© Copyright OCIMF 2011. All rights reserved. 93 8.17.28 Are all mud and brine tanks, pumps, valves and pipeline systems in good order and fully tested?
8.17.29 Is all deck mounted equipment, control skids and storage containers in good order and provided with appropriate cautionary signage?
Exhausts, dangerous chemicals, hot pipes, pressurised pipes, radioactive sources should all be identified and managed within the vessel/unit's SMS.
8.17.30 Are all connections and deck pipework for bulk products, such as water and fuel, colour coded and clearly marked at loading stations?
Includes all bulk products, both liquid and non-liquid.
8.17.31 Are any transfer hoses fitted with lifting saddles and stowed in racks?
All hoses should be suspended in arrangements that avoid sharp bends and protrusions wherever possible.
Where fitted, the saddle and rack arrangement should be a permanent structure with appropriate foundations. All lifting gear used in the hose arrangement should be certified and inspected on a periodic basis. Reference: Step Change - Bulk Hose Best Practice Guidelines.
8.17.32 If carried on board, are transfer hoses fitted with flotation collars?
Especially those for hydrocarbon or NLS. Check also fitted with reflective tape.
