Oil & Product Carriers
Proven Tank Protection Systems for Crude and Refined Product Tankers
Oil and product carriers operate under strict safety, environmental and operational requirements. Cargo volatility, loading rates, inert gas management and vapour emission control all place high demands on the vessel’s tank protection system.
At Pres-Vac Engineering, we deliver certified pressure/vacuum valves and venting systems specifically engineered for crude oil tankers and product carriers. Our solutions ensure regulatory compliance, minimise cargo loss and enhance crew safety – while maintaining stable tank pressure throughout loading, voyage and discharge
Designed for Demanding Tanker Operations
Crude oil and refined products generate significant vapour volumes during loading and transport. Approx. 0.2% of cargo may be lost through vapour emissions if systems are not optimised, with a substantial share occurring during voyage.
Maintaining constant tank pressure is therefore critical.
Our high velocity pressure vacuum valves are designed to:
- Maintain precise pressure control within defined limits
- Reduce blowdown pressure compared to conventional weight-loaded valves
- Minimise unnecessary vapour release
- Prevent risk of tank deformation due to overpressure or vacuum
- Operate reliably without oscillation or hammering
The result is a safer vessel, reduced emissions, and improved cargo retention.
Additional Tanker Components
Depending on vessel design and operational profile, Pres-Vac also supplies:
- DH150 high-capacity venting solutions
- Specialised vent covers and protection systems
- Integrated solutions adapted to inert gas systems (IG)
All systems are engineered in close dialogue with shipyards, owners and classification societies. vapours.
Compliance with IMO and Industry Standards
Oil and product carriers must comply with stringent international regulations. Our pressure vacuum safety valves and tank protection systems are:
- Approved by all major classification societies
- Compliant with IMO and EU-MED requirements
- Tested according to ISO 15364 and ISO 16852
- Designed to meet API 2000 operational criteria
We actively participate in regulatory development, ensuring the highest safety for vessel and crew and ensuring that our solutions not only meet but often exceed current and known forthcoming standards.
