2. Amended conditions for berthing seagoing tankers at non-tanker berths
Seagoing Tankers, and specifically chemical tankers, regularly need layby berths in our port, to wait between operations, to prepare tanks or to receive essential services such as bunkering, stores and spares. The number of tanker berths is limited and busy, which means that they can only be used to a limited extent as a layby berth for these ships.
In order to expand the range of layby berths for tankers, the conditions in the Port Instructions for mooring and carrying out specific activities of tankers at non-tanker berths have been further amended in Article 126.96.36.199. This concerns the conditions for the following activities, up to a maximum residence time of 72 hours:
- controlled degassing
- delivery of residual washwaters and slops
What is changing?
Since the tankers have already reached a certain safety state before berthing, the safety zone condition that had to be delimited and controlled has been removed from the conditions.
For planned controlled degassing, a tanker may shift to the non-tanker berth provided that the operation starts within 12 hours of arrival at the layby berth, whereby a safety zone with a safety watch must be established until the degassing operation has been completed.
What won't change?
The condition of the tanker must be verified at the start of the berth stay and, for liquids with a flash point less than or equal to 60°C, monitored every 24 hours by a recognized gas expert, with all tanks within the cargo area (cargo tanks, slop tanks, ROT ,…) must meet one of the following conditions:
- LEL < 10%
- Inert (O2 < 8 vol%)
All other handling of goods on board tankers remains prohibited at non-tanker berths.
All waterborne concessions determine themselves whether their activities allow these stays and activities of tankers. The agents of the seagoing vessels involved must in turn obtain the concessionaire's agreement for the taking up of these berths by a tanker.
