STATEMENT OF WORK:

1.6 Electrical Safety - Lock-out/Tag-out Procedures

1.6.1 The Contractor shall have an established electrical safety lock-out/tag-out program in place to provide adequate protection against electrical hazards in the accomplishment of the work specified in this work package. A written description of the contractor’s electrical safety lock-out/tag-out procedures shall be provided to the MSCREP, ship’s Master and Chief Engineer upon vessel arrival at the contractor’s facility, along with a discussion on the procedures.

1.6.2 Ship’s force shall maintain their existing lock-out/tag-out procedures, in accordance with reference 2.1 for low voltage applications and reference 2.2 for high voltage applications, in addition to the contractor’s procedures, to provide a redundant safety measure for these systems. The contractor shall co-ordinate electrical safety lock-out/tag-out procedures with the MSCREP and the ship’s Chief Engineer to ensure the plans complement each other and provide maximum electrical safety for ship’s crew and contractor personnel.

1.6.3 Do not accomplish work on any piece of mechanical, electrical or electronic equipment, circuit, or system that has not been isolated from its energy source (electrical, mechanical, hydraulic, pneumatic, chemical, or thermal) and tagged-out in accordance with the shipyard’s electrical safety plan and references 2.1 and 2.2.

1.6.4 Do not attempt to operate any piece of mechanical, electrical or electronic equipment, circuit, or system that is tagged-out by either the contractor, ship or both. Tags must be properly cleared through both the contractor’s procedures and the ship’s procedures before systems and equipment can be safely energized and operated.

1.6.5 All contractor and subcontractor personnel intended to work on electrical circuits and equipment onboard MSC vessels shall provide and utilize proper personnel protective equipment (PPE) and tools in accordance with references 2.3 and 2.4. Contractor and subcontractor personnel will not be permitted to perform electrical systems work onboard if they are found to not possess the proper tools and PPE.

1.7 High Voltage Systems (T-AKE 6600V Systems)

1.7.1 Ensure all Contractor and sub-Contractor personnel comply with the ship’s High Voltage System procedures (T-AKE Vessels) of reference 2.2, in addition to the contractor’s internal procedures.

1.7.2 Obey all High Voltage (HV) signs and verbal directions of the ship’s force “Competent Person In-charge” (CPIC).

1.7.3 Ensure all Contractor personnel possess awareness and exercise vigilance regarding HV safety, watch for all signs indicating HV, and take prudent action to preclude unauthorized entry into HV areas.

1.7.3.1 Provide formal briefing to all Contractor and sub-Contractor personnel of HV concerns.

1.7.3.2 Submit a report to the MSCREP listing all personnel formally briefed on HV safety no less than five (5) days prior to start of the period of performance.

1.7.4 Do not disturb, cut, move or damage HV cables in any fashion.

1.7.5 Do not paint HV cables.

1.7.5.1 Temporarily mask, cover or protect HV cables when painting in spaces that contain HV cables.

1.7.6 Do not work on or test HV equipment:

1.7.6.1 For which Contractor personnel do not possess a ship’s force issued “High Voltage Permit to Work” (HVPTW) or "High Voltage Sanction For Test” (HVSFT) permit.

1.7.7 Ensure only Contractor and sub-Contractor personnel designated as “qualified” work on HV equipment.

1.7.7.1 Prepare a list of all Contractor and sub-Contractor personnel identified as “qualified” to:

a. Work in HV spaces

b. Work on HV equipment.

1.7.7.2 Include on the list the specific type of formal qualification training possessed by each individual.

1.7.7.3 Submit copies of the list to the MSCREP and the ship’s Chief Engineer before any individual commences HV permit request.
