Justificación del estudio

8.5.1 Does the vessel/unit have a competence/training matrix that addresses crane and ballast control operations?

Spot check training, experience and certification records. Check that refresher training is in place for specialist positions such as offshore crane operators and ballast control operators.

8.5.2 Does the company have documented procedures in place to ensure that the Master is provided with necessary pre-voyage guidance?

Guidance should be provided on issues that include weather restrictions, voyage routeing, motion limitations, project specific lift analysis and transport manual.

8.5.3 Does the vessel/unit have a competence/training matrix that addresses crane and lifting gear maintenance activities?

Spot check training and certification records. Check that the vessel/unit's crew are trained and certified for inspecting lifting equipment.

8.5.4 Is there an effective lifting equipment management system in place?

To include:

• the marking of all equipment to correspond to a certificate

• availability of all certificates on board

• clear criteria for retirement of wires

• controls to prevent the unauthorised modification of lifting equipment.

8.5.5 Are all lifting operations formally risk assessed?

8.5.6 Are there documented procedures and general safety arrangements in place for activities on the exposed working decks?

Including requirements for PPE, lifejackets and lifebuoys. Check safety signage and availability of fall arrestor equipment for more than one person to use in exposed areas.

8.5.7 Do the emergency procedures cover additional risks associated with the vessel/unit's heavy lift operations?

8.5.8 Is there a competent person in charge of ballast control and stability calculations?

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. Comprehensive Stability Courses have been developed and approved by the IADC / NI which after completion of specified seatime and completion of a log book may result in the issue of a Ballast Control Operator Certificate.

8.5.9 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.

8.5.10 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 transfer of cargo that calculations have been made for stress and stability conditions for the start, interim and completion of transfer conditions. Regular monitoring of stress and stability should be taking place throughout cargo transfer to ensure that the conditions have been maintained within design limits.

8.5.12 Are draft gauges operating correctly?

Check the procedure for calibration and cross reference to visual and loading computer values.

8.5.13 Is there a system for training and drills covering the stability issues associated with ballast, bilge and crane systems, in both normal and emergency conditions?

Check that regular drills have taken place using the emergency ballast and bilge control system.

8.5.14 Is there a system of verifying and recording the calibration of tank gauging systems and level alarms?

Tanks should be manually sounded at least once per week and compared to remote reading gauges.

Discrepancies should be recorded and available to the BCO. Ensure that sounding tubes are not blocked and that sounding pipes are marked indicating the tank served and are fitted with a cap.

8.5.15 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.

8.5.16 Are lightweight changes effectively incorporated into stability calculations?

System of cross checking to assure manual inputs. Inspector to verify that inventories of variable weights appear reasonable and accurate.

8.5.17 Are the ballast and bilge systems covered by an FME(C)A?

8.5.18 Is there a system for controlling the override of bilge and ballast system alarms?

To be covered in procedures and documented.

8.5.19 Is access to the ballast control panel restricted?

System to be in place to prevent unauthorised operation of bilge and ballast system.

8.5.20 Is the ballast control position attended continuously during lift operations?

Ballast station to be manned continuously to ensure prompt action can be taken when required.

8.5.21 Are all watertight doors, hatches and other openings on or near submersible decks in good order?

Seals, locking devices and remote indicators should be in good order and fully functional.

8.5.22 Is there a positive feedback/checklist system for ensuring all such openings are secure for appropriate stages of the operation?

Check past records for compliance with procedures and best practice.

8.5.23 Is access to crane controls restricted?

Security system should ensure that unauthorised operation is prevented.

8.5.24 Is the main crane control console continuously attended by a qualified crane operator when lifting?

8.5.25 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.

8.5.26 Are crane alarm systems all operational and in good order?

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.

8.5.28 Are pumproom emergency bilge suction valves clearly marked, fitted with a position indicator and capable of remote operation?

8.5.29 Is the emergency bilge suction and pump tested and are records maintained?

Record method and date of last test.
