Safety Regulations and Inspections

Part 3 - Terminal Safety Regulations

3.0 Safety Regulations
Nothing in these regulations will relieve Masters of their responsibilities in observing the normal safety, fire prevention and security precautions. Chevron Mooring Masters are authorised to advise and request Master to take additional measures to ensure safe operations should circumstances so require. Chevron Mooring Masters are also authorised to suspend oil transfer operations in the event of an infringement of safety regulations or if any other hazardous situation is encountered.


3.1 Safety Requirements
Masters will be given the Chevron Safety Requirement Letter by the Chevron Mooring Master prior to commencement of berthing operations, and a signed acknowledgement will be required.


3.2 Safety Checklist
On completion of berthing and prior to the commencement of deballasting or cargo loading, the Muanda Terminal Safety Checklist will be completed following a joint inspection by the Chevron Mooring Master and a responsible export tanker's officer. The Chevron Safety Checklist is based on the recommendations of the "International Safety Guide for Oil Tankers and Terminals" (ISGOTT).


3.3 Inert Gas System
All the tankers calling at Muanda Terminal should arrive with the cargo tanks inerted to 8 percent dioxine
or less by volume and pressurized as required by the SOLAS Convention. All the vessels will be checked prior to berthing and rejected if found not in compliance with the above requirement.

(a) Tank Inspection, Gauging, Sampling, Water Dips and Temperatures
Should it be necessary for tanks to be inspected, then it should only be done on a tank-by-tank basis. The system shall be maintained at about 200 mm water gauge except for the individual tank to be opened which, if possible, is to be isolated from the system and the sighting port opened with care. On completion of inspection the tank shall be secured and re-pressurized. The next tank is not to be isolated and opened until the preceding tank is secured and open to the IGS system.


All gauging, sampling, water dips and temperatures will be taken either through special fittings provided; or if it is necessary to open up tanks for this purpose, then this will be done one (1) tank at a time as described above.

(b) Failures of IGS
If at any time the IGS is not maintaining the prescribed conditions, the Chevron Mooring Master shall
order a suspension of transfer operations. The cost of any delays will be for the export vessel's account.


3.4 Ship/Ship Communication
Communication between the two (2) vessels will be by portable VHF radios provided, if necessary, by Chevron. They shall be tested and found satisfactory before transfer operations commence. The export tanker's responsible officer, the Chevron Mooring Master and the "Chevron Zenith" shall confirm with each other that the communication system and signals for the controlling the operations are understood by all personnel involved prior to the commencement of deballasting or cargo loading.


3.5 Emergency Procedures
As required by the Muanda Terminal Safety Checklist, the Master of the export Vessel and the Chevron Mooring Master should discuss and agree upon the action to be taken in the event of an emergency or a fire on board either the export tanker or the "Chevron Zenith". This should include means of communication and emergency procedures. The Master of the export tanker shall provide the Chevron Mooring Master with a copy of the export tanker's Emergency Organisation and Contingency Plan.


3.6 Operating Procedures
Procedures for cargo and ballast operations shall be agreed in writing between the Chevron Mooring Master and the export tanker's Master and Chief Officer.


3.7 Fire Precautions
The export vessel's fire fighting appliances, including main and emergency fire pumps, shall be kept ready for immediate use, and pressure shall be maintained at all times on the fire main while in berth. Before operations commence, at least two (2) fire hoses with jet/fog nozzles shall be laid out on the tank deck, connected to the fire main and tested as required by the Chevron Mooring Master. The two (2) fire monitors immediately adjacent to the manifold should be elevated and made ready for immediate use. A fire pump shall maintain pressure on the fire main and be ready for immediate use. Two (2) portable fire extinguishers, preferably of the dry chemical type, shall be available in the proximity of the manifold area.


3.8 Conditions To Be Observed On Board The Export Tanker During Transfer/Deballasting Operations
(a)
A responsible, English speaking ship's officer is required to be on deck or in the control room at all times. A continuous deck watch is to be maintained to ensure moorings are carefully tended and cargo hoses are under observation at all times.


(b) Towing off wires shall be made fast to bit's as far forward and aft as possible on the starboard side. The wires shall be in good condition, at least 1-1/8" (28mm) diameter, and secured with at least five turns or have the eye on the bit's. The outboard eye shall be maintained at a height of between 1 metre and 2 metres above the water at all times using a small diameter heaving line for this purpose.


(c) All doors, portholes and opening leading from or overlooking the main deck to accommodation, machinery spaces (excluding pump room) and forecastle shall be kept closed. Cargo control room doors opening on to or above the main deck may be opened momentarily for access.


(d) All ventilators through which gas can enter accommodation or machinery spaces shall be suitably trimmed. Air conditioning units shall be stopped or operated in a recirculation mode. Window type air conditioning units shall be electrically disconnected.


(e) The venting of the vessel's tanks shall take place only through the vessel's fixed venting system.


(f) Sighting and ullage ports when not in use shall be kept closed. When any are open for operational reasons, the openings shall be protected by approved gauze flame screens. These screens shall be kept clean and in good condition. Portable screens should be a good fit.


(g) If for any reason there is poor dispersion which results in an accumulation of gas on for about the decks of either vessel, loading shall be stopped or the loading rate into a particular tank or tanks reduced at the discretion of either the Chevron Mooring Master or the responsible ship's officer.


3.9 Smoking
Smoking is strictly prohibited while at the berth except in designated areas which have been jointly approved by the Master and by the Chevron Mooring Master.


Smoking notices specifying the designated smoking areas shall be exhibited in conspicuous places on board the vessel. Where smoking is approved on vessels, approval may be withdrawn by the Chevron Mooring Master is circumstances so warrant.


3.10 Matches and Lighters
The carrying and use of matches and lighters are prohibited on board the export tanker while at berth except under controlled circumstances in the designated smoking areas.


3.11 Portable R/T Sets, Lamps and Hand Lamps
Portable R/T sets, lamps and hand lamps, or other electrical devices shall not be used unless approved as intrinsically safe. The use of portable electric lamps and equipment on extension cords or wandering leads is prohibited in any cargo or adjacent ballast space, pump room, coffer dam, forecastle, bunker compartment, hold or anywhere over the cargo tanks.


Portable domestic radios, photographic flash equipment, portable electronic calculators, tape recorders and any other battery powered equipment not approved as intrinsically safe must not be used on the tank deck area of either vessel nor in any other place where hazardous vapours may be encountered.


3.12 Movement of Tugs, Work boats and Other Craft
During transfer operations no craft shall be allowed alongside the export vessel unless approval has been given by the Chevron Mooring Master and agreed by the Master of the export tanker.


3.13 Repair Work
A vessel secured to the Export Buoy shall be maintained in a state of readiness for vacating the berth under full engines power at short notice. Therefore, no repairs will be permitted. The testing of any electrical equipment, is prohibited unless the permission of the Chevron Mooring Master has been granted. Tank cleaning and gas freeing shall not be carried out while in berth. Chipping and scraping on the deck or hull will not be permitted.


3.14 Prevention of Sparking and Excessive Smoke
Soot blowing and excessive smoke are prohibited, and immediate steps shall be taken to eliminate any sparking from funnels/stacks. All vessels shall be fitted with stack flame arresters.


3.15 Avoidance of Oil Pollution
During transfer operations all scuppers shall be effectively plugged, fixed or portable manifold oil containment shall be in place, and no leakage or spillage of oil or water which can possibly contain oil shall be allowed to escape overboard. Scupper plugs may be removed to drain off accumulations of water periodically and replaced immediately after the water has been run off. Manifold containment should be drained before transfer operations commence. Any leakage or spillage must be reported immediately to the Chevron Mooring Master.


Should oil spillage occur during deballasting or loading operations, then all such operations shall cease immediately and action taken to control and contain the spillage. Cleaning up operations shall be started immediately, and loading operations will not be resumed until remedial action has been completed to the
satisfaction of the Chevron Mooring Master.


No hazardous material shall be thrown overboard, nor shall any other objectionable material, either solid
or fluid, be thrown overboard from the vessel. This includes plastics, synthetic propers, plastic garbage
bags, paper products, rags, glass, metal, bottles, crockery, dunnage and packing material


3.16 Galley Stove and Other Cooking Equipment
The use of galley stoves and other cooking equipment shall be permitted, provided the Master and chevron Mooring Master agree to their use.


3.17 Transmitting Aerials
When a vessel is on the berth, the main transmitting equipment, including secondary/emergency transmitters, shall only be used with the approval of the Chevron Mooring Master. At all times antennas for such equipment should be grounded. Satellite communications equipment may only be used with the approval of the Chevron Mooring Master.


3.18 Tank Lids
All cargo tank lids, ullage and sighting ports shall be securely closed before berthing or unberthing operations commence. During cargo transfer operations all cargo, ballast and bunker tank lids and tank washing openings shall be securely closed.


3.19 Unused Connections
All unused cargo and bunker connections shall be properly blanked, fitted with a gasket and bolted with at least a bolt in every other hole at the manifold. Stern cargo pipelines (if fitted) shall be isolated forward of the aft accommodation by blanking or by removal of a spool piece.


3.20 Sea and Overboard Discharge Valves
On completion of clean ballast discharge, all sea and overboard valves connected to the cargo or ballast system shall be closed and kept so throughout the stay of the vessel into the berth. The sealing of said valves will be performed by the cargo surveyor if appointed to do so. A careful watch shall also be maintained to ensure that oil does not leak through the sea and overboard valves.


3.21 Breakdown of Communications
In the event of a total breakdown of radio communications on either the storage vessel or export vessel during deballasting or cargo transfer operations, then these operations shall be immediately suspended and not resumed until satisfactory communications are re-established.


3.22 Emergency Escape
Means for emergency escape shall be provided preferably on the starboard side of the export tanker.
For security reasons such means are to be stowed at deck level in such a manner as to be ready for
use in an emergency. Such means shall be of adequate length to reach the water at all times.


3.23 Radar - Satellite Communications Terminals - Closed Circuit Television
The use of this equipment for any purpose is prohibited during the period that the export vessel is in berth, except with the approval of the Chevron Mooring Master (See 3.17)


3.24 Cargo Tank Venting
IGS venting will be permitted during loading operations, and this should be done via the IGS vents. For gauging, sampling, etc., controlled release of inert gas will be permitted if found necessary. (See 3.3)


3.25 Conditions Requiring Immediate Action
Deballasting and cargo transfer operations shall not be started, or if started, shall be discontinued by either the responsible officer of the export vessel or the Chevron Mooring Master when any of the following conditions are noted:


(a) On the approach of and during electrical storms, heavy rainstorms or periods of high winds, all tank
openings and cargo valves shall be closed and vessel is to be inerted with IGS plant on line.


(b) If a fire occurs on the storage vessel, the export vessel or any craft in close proximity.


(c) If there are insufficient competent personnel aboard the export vessel to safely handle the operation in progress, and to handle any emergency situation.


(d) If a spill occurs either aboard the vessel or on the buoy, if cargo hose fails, or serious leaks are encountered at flanges and connections.


(e) If any other emergency situation arises which, in the opinion of the export vessel's responsible officer or the Chevron Mooring Master, constitutes a potential hazard to either of the two ships or facilities.
