In my previous post, we have discussed about pre-bunkering preparation and bunkering operation in particular and the described procedure applies in every port where the vessel intend to bunker. However, there are some specific requirements with regard to oil transfer onboard vessels and US authorities issue a set of rules that must be followed if the vessel intends to bunker in any of US ports.

Bunker barge alongside vessel
The Master of the vessel must notify the port authority of the intention to bunker well in advance, stating the location, type of bunker, oil to be transshipped, and the expected time of bunkering.
C/E will hold a meeting with all ship’s staff who will be involved with or responsible during bunkering on a bunkering plan at least 24 hours prior to bunkering operations, where the following will be discussed and agreed upon:
-
- Roles and responsibilities specific to assigned task of each individual
- Tanks that will be made available for bunkering
- Plan on extent of filling of each tanks
- Valves to be lined up for the operations
- Closing of scuppers on deck
- Communications between supply vessel and receiving vessel
- Flow rate
- Frequency of checking tank soundings
- Spill response

Pre-bunker meeting held onboard vessel
The above is intended as a guide and does not exclude any other possible scenarios that the C/E and his engine room staff would like to implement.
Pre-bunkering Check list is to be filled in for compliance. All check lists are to be maintained on board at least for a minimum period of two years from date of bunkering or as per company management system instructions.

Example of pre-bunker checklist
As mentioned in my previous post (which can be found in here) before bunkering begins, the Chief Engineer must double-check all details on the delivery papers as presented by the barge supplier’s representative to ensure that the bunkers delivered match the quantity and specifications stated in the prior Bunker Confirmation message.
Chief engineer and his / her designated engineers shall verify that the following is also complied with prior to commencement of bunkering.
- All self closing devices on sounding pipes operate correctly and easily, and closed after use.
- Prior to bunkering air pipes from all tanks are in order. This includes checking that the safety gauze is not blocked with paint thus reducing the air flow. Where Press/Vac valves are fitted, they shall be checked for free movement.
- Heavy fuel oil vapours are measured for Hydrogen Sulphide (H2S), preferably on board the barge. The acceptance level of H2S in the tank atmosphere is up to 200 ppm. If H2S in the tank
atmosphere is found in excess of 200 PPM, the fuel should be rejected and the parties in barge of vessel’s bunker supply notified accordingly. About H2S will discuss on a later post.
Apart from above, below there is a summary description of the USCG requirements pertaining oil transfer operations.

Code of Federal Regulations 33
For whoever is interested the code can be found in here.
As per USCG 33 CFR 156.120 Requirements for transfer a transfer is considered to begin when the person in charge on the transferring vessel or facility and the person in charge on the receiving facility or vessel first meet to begin completing the declaration of inspection, as required by §156.150 of this part. Therefore, no person shall conduct an oil or hazardous material transfer operation unless:
- The vessel’s moorings are strong enough to hold during all expected conditions of surge, current, and weather and are long enough to allow adjustment for changes in
draft, drift, and tide during the transfer operation; - Transfer hoses and loading arms are long enough to allow the vessel to move to the limits of its moorings without placing strain on the hose, loading arm, or transfer piping
system; - Each hose is supported to prevent kinking or other damage to the hose and strain on its coupling.
- Each part of the transfer system is aligned to allow the flow of oil or hazardous material;
- Each part of the transfer system not necessary for the transfer operation is securely blanked or shut off;
- The end of each hose and loading arm that is not connected for the transfer of oil or hazardous material is blanked off using the closure devices required by §§154.520 and

- Each transfer hose has no unrepaired loose covers, kinks, bulges, soft spots, or any other defect which would permit the discharge of oil or hazardous material through the
hose material and no gouges, cuts, or slashes that penetrate the first layer of hose reinforcement (“reinforcement” means the strength members of the hose, consisting of
fabric, cord and/or metal); - Each hose or loading arm in use meets §§154.500 and 154.510 of this chapter, respectively;

exceed the capacity of the discharge containment provided during the transfer operation; - The communications required by §§154.560 and 155.785 of this chapter are operable for the transfer operation;
- The emergency means of shutdown required by §§154.550 and 155.780 of this chapter, as applicable, is in position and operable;

As per USCG 33 CFR – 156.125 Discharge cleanups the following should be taken into account:
- Each person conducting the transfer operation shall stop the transfer operation whenever oil or hazardous material from any source is discharged:
(a) In the transfer operation work area; or
(b) Into the water or upon the adjoining shoreline in the transfer area. - Except as permitted under paragraph (c) of this section, no person may resume the transfer operation after it has been stopped under paragraph (a) of this section, unless:

USCG 33 CFR – 156.130 Connections
- Each person who makes a connection for transfer operations shall:
(a) Use suitable material in joints and couplings to ensure a leak-free seal;
(b) Use a bolt in at least every other hole, and in no case less than four bolts, in each temporary bolted connection that uses a flange that meets American National Standards

In addition, for vessels entering the North American ECA, should notify all relevant authorities in cases of fuels that does not reach the sulphur requirements of the ECA. This should be done in any of the following cases:
- BDN is non-compliant
- BDN is compliant, but post-test analysis is non-compliant
- Compliant fuel is not available.
