Building resilient jetty structures for oil & gas and maritime operations with precision engineering and regulatory compliance.
The Role of Jetty Infrastructure
Jetties are critical pieces of maritime infrastructure, providing the physical interface between sea-based vessels and land-based operations. In the oil & gas and petrochemical sectors, jetties must support product loading and offloading arms, mooring systems, fire protection infrastructure, emergency systems, and in many cases, live process piping — all while withstanding the continuous forces of tidal currents, wave action, and vessel mooring loads.
The engineering of a jetty is therefore a multi-disciplinary challenge spanning structural, civil, marine, mechanical, and process engineering.
Key Engineering Considerations
Foundation Design
Jetty foundations in marine environments must address varying seabed conditions, scour potential, and long-term settlement. Driven steel piles, bored concrete piles, or composite solutions are selected based on geotechnical survey data and loading requirements.
Structural Integrity in Corrosive Environments
Marine structures face aggressive corrosion from seawater, salt spray, and biological fouling. Material selection (high-specification steel grades, stainless, or GRP), protective coatings, cathodic protection systems, and regular inspection regimes are essential to achieve design service life.
Berthing and Mooring Loads
The structure must absorb the kinetic energy of vessels during approach berthing, as well as sustained mooring loads from environmental forces. Fendering systems, mooring hardware, and bollard calculations are critical design inputs.
Construction Execution
Jetty construction in the maritime environment introduces execution complexity not present in onshore work:
- Pile installation and concrete works are subject to tidal windows and weather holds
- Marine plant (jack-up barges, crane vessels) must be coordinated with vessel traffic management
- Intertidal and submerged work requires marine construction specialists and diving crews
- Safety management for simultaneous marine and structural construction activities requires detailed SIMOPS planning
Regulatory and Environmental Compliance
Jetty projects require engagement with multiple regulators including port authorities, maritime authorities, and environmental agencies. Environmental impact assessments, dredging permits, and marine disposal approvals are standard requirements. BIWERG's construction team manages the full permitting and compliance process as part of our project delivery scope.
Our objective on every jetty project is the same: a structurally sound, safely built, fully compliant maritime asset delivered on programme and within budget — ready to serve its operational purpose for decades.
